Wheels Be Balanced

unduhan-63Smooth driving is a balancing act that requires getting the wheels and tires to rotate at high speeds without vibrations. That’s not a slam dunk; a dirty little secret about wheels and tires is that they usually aren’t perfectly round, even when brand new. What’s more, their weight often isn’t evenly distributed, so they’re heavier in some spots than others.

Either issue can cause annoying vibrations. Out-of-balance tires can also cause rapid tire or suspension wear, so it’s not just about ride comfort.

That is why when new tires are mounted on wheels they’re spin-balanced to detect vibrations. Some vibrations can be eliminated by rotating the tire on the wheel so the heavy or “high” spot is in a different location that better matches up with the wheel. Small weights are attached to the wheels with adhesives or clips to counteract the heavy spots and provide a smooth ride. Over time, though, the weights can fall off. If that happens to a front wheel, you may feel vibrations through the steering wheel that typically become more pronounced as vehicle

Mileage Engines Worth the Extra Cost

unduhan-62Most major oil brands market oil made specifically for engines that have more than 75,000 miles of wear, claiming that additives help reduce engine wear and provide anti-aging benefits. They are often a blend of synthetic and petroleum-based oils, and they typically cost at least a couple of dollars more per quart than conventional oils.

But are they worth the extra dough?

Some oils may be more beneficial than others because they contain conditioners purported to rejuvenate seals to prevent or stop oil leaks, a common ailment in engines with a lot of miles on them.

Internal seals and gaskets become brittle and shrink as they age, allowing oil to seep by. Sometimes this becomes visible as oil stains on a garage floor or as streaks of oil on lower engine parts. When valve-guide seals wear, oil can leak into combustion chambers and the engine will literally start burning oil. With small leaks, blue smoke from burning oil may not be visible from the exhaust, but your oil level will probably drop below the full mark on a

Change Engine Coolant Tips

images-59For some vehicles, you’re advised to change the coolant every 30,000 miles. For others, changing the coolant isn’t even on the maintenance schedule.

For example, Hyundai says the coolant (what many refer to as “antifreeze”) in most of its models should be replaced after the first 60,000 miles, then every 30,000 miles after that. The interval is every 30,000 miles on some Mercedes-Benz models, but on others it’s 120,000 miles or 12 years. On still other Mercedes, it’s 150,000 miles or 15 years.

Some manufacturers recommend changing the coolant more often on vehicles subjected to “severe service,” such as frequent towing. The schedule for many Chevrolets, though, is to change it at 150,000 miles regardless of how the vehicle is driven.

Many service shops, though — including some at dealerships that sell cars with “lifetime” coolant say you should do it more often than the maintenance schedule recommends, such as every 30,000 or 50,000 miles.

Here’s why: Most vehicles use long-life engine coolant (usually a 50/50 mixture of antifreeze and water) that for several years

Car battery in new car

Though battery problems are often associated with cold weather, Consumer Reports magazine says heat is a bigger enemy of car batteries and will take a bigger toll on performance and reserve capacity. The magazine recommends that vehicle owners in hotter parts of the country have their car battery tested after two years of ownership and then every year after. Those who live in colder areas can wait four years to test performance and capacity, and then every year after.

“Heat kills batteries,” according to John Banta, a Consumer Reports project leader and part of the team that tests batteries for the magazine. “Many times in cold climates your battery fails to start your car on a below-freezing day. The reason this happens is that the heat of the past summers has weakened your battery. When you use it in the cold, the starter requires more electrical current to turn over the cold engine with its thickened oil.”

Testing a battery’s performance and reserve (or amp-hour) capacity is not just a matter of seeing whether it will hold a charge (or checking the electric eye found on some batteries to see if it is green), so testing

When Should You Replace It an Air Filter

The cabin air filter, a feature found on most late-model vehicles, cleans the air that comes into the interior through the heating, ventilation and air-conditioning system. It catches dust, pollen and other airborne material that can make riding in a car unpleasant, particularly if you have allergies or other respiratory problems.

Recommendations on when it should be replaced vary by manufacturer — some say every 12,000 or 15,000 miles, others longer — and how often can depend on how much you drive and where. Check the maintenance schedule in your owner’s manual. If you drive in heavy traffic in an urban area that has poor air quality, you could need to replace the filter annually or even more often. However, that also could be true in a desert climate where there is a lot of dust.

Some signs that you need a new cabin air filter are reduced air flow through your climate control system, such as when you crank up the fan too high and get more noise than results. Another is persistent bad odors. Even if you don’t have these warnings, you should have the filter checked at least once a year, and you

Automotive Radical Innovation In Urban Transpor

The Mobilicity system is an automated, driverless system for GRT or Group Rapid Transit. It functions as an advanced bus or taxi substitute in a wide variety of situations. This approach offers significant environmental benefits, allowing its users to address the major problems associated with urban mobility: congestion, air quality, noise and fossil fuel use.

The Driverless Mobilicity

It is cheaper to operate than a conventional bus system and offers unrivalled flexibility in operation. The electric vehicles operate on any graded road surface and require no specific infrastructure; this is a major competitive advantage over its only current competition.

As typical new urban developments commit 30% of the available land to the private car for roads and parking, the application of the Mobilicity approach can reduce this to 8%; a very significant amount of land released for other uses.  Further, it can also bring benefits in sensitive areas such as historic city centres where it can improve the environment without any structural impact.

Mobilicity has no direct competitors. Its closest rival is the PRT or Personal Rapid Transit sector. As an example, the Ultra PRT system, which uses a car-sized vehicle requiring extensive infrastructure,

Applications In Automotives

Power applications in automotives are dynamically experiencing changes and improvements. One of the benefits of slimming down the vehicle body weight is less power energy consumption. Getting more kilometers out of the same amount of energy can be possible by fully exploiting the technology available in the market. A multitude of innovative concepts, technologies and materials are in the market and are used in the vehicles and transport carriers today. The relative high costs associated hindered the development and implementation of advanced materials and production technologies.
Potential novel materials applications have large scope, but the focus on two issues:

  • The development of innovative materials for batteries based on nanotechnology
  • The development of new light weight materials and respective technologies for vehicle applications.

We already discussed reducing structural weight in Automotives Body Weight Reduction that discussed on different materials role in reduction of body weight of automotives. While, innovative automotive electrochemical storage applications based on nanotechnology technical content and scope is:

Ford has come up with volume production plans for large-capacity Li-ion rechargeable batteries that are being made targeting electric vehicles and other applications in automobiles. As per Ford, Li-Ion batteries are the obvious energy storage option

Absorbers In Automotives

A shock absorber is basically an oil pump, a device used to smooth the push or shake that take place abruptly and roughly and distribute it as kinetic energy. Shock absorbers are crucial in all the motorcycle and automobile suspension, where landing gear is a part of the support systems for industrial machines. A shock absorber is usually a cylinder containing a sliding piston which is cushioned by hydraulic fluid or air.

During 1900’s cars use to ride on carriage springs, which are a simple form of spring commonly used for the suspension in wheeled vehicles. With respect to suspension designs, the initial vehicle manufacturers faced early challenges in enhancing driver control and comfort of passenger. These early suspension designs found the front wheels attached to the axle using steering spindles and kingpins, those allowed the wheels to pivot while the axle remained stationary. Other than these, the up and down oscillation of the leaf spring was damped by device called a shock absorber. The initial shock absorbers were simply two arms connected by a bolt with a friction disk between them and were not very durable. Here the resistance was adjusted by tightening or loosening the

Innovative Automotive Solutions

Windows Embedded Automotive has spent more than 15 years enabling vehicle-based infotainment systems that let drivers control their car stereos, mobile phones and other devices with voice commands. Consumers have since come to expect that they can access and share information — even while they’re driving. They have traded the legacy driving aids of the AM radio and road atlas for entertainment, navigation and communication services.

The in-car infotainment systems are now one of the top selling points and are helping the automotive industry create what it calls the “connected car.” Depending on the system they’ve selected, drivers can listen to text messages, connect to social media, receive driving directions and more, all without taking their eyes off the road or their hands off the wheel. The connected car is one more example of what Windows Embedded calls intelligent systems.

Achieving Cleanliness Reliably And Efficiently

Component cleanliness is a quality criterion in the motor vehicle industry. Requirements are becoming stricter and stricter with each vehicle generation – with simultaneously increasing cost pressure. And thus for the automotive industry and its suppliers it’s becoming more and more important to exploit optimisation potential in the area of parts cleaning.

Global emphasis is being placed upon reducing CO2 emissions and fuel consumption, as well as increasing safety and comfort within the vehicle manufacturing industry. Downsized engines are in demand which run more efficiently with high power output, as are components that are capable of withstanding extreme loads and are distinguished by tight tolerances. However, this is only possible with high precision components – and this is associated with increased sensitivity to contamination. If they end up in the wrong place, even particles with sizes down to 500, 200 or even just 100 µm can cause damage and failure in the field. This is why, in the meantime, the automotive industry has started defining particle size distributions for certain parts in functional modules such as the power train, steering and brakes, for example no more than 1,000 particles between 100 and 200 µm, 500 particles between

All About Automotives Body Weight Reduction

The trend of light weight vehicles took peak during the starting of 20th century with 17.4 million unit’s sale in US annually and sustained at 16 million units through 2007. Though the 2008 debt financing affected the motor vehicle bubble, the investments in research & development of automotives didn’t hinder at the same rate. While the annual U.S. light vehicle sales reached their lowest point in 2009 and started increasing since then. The majority value of the global automotive industry is parts sector, but the importance of light weight vehicles globally gave a penetrating angle for the investors to do investments in the new materials and technologies like light weight & bio-based automotive materials in plastics & metals that are almost replacing  the whole body structures in automotive front-end modules at an accelerated rate.
All these industry efforts are to acquire the untapped market in developed and developing counties that is eagerly waiting for the light weight vehicles because of the high emphasis on growing oil prices and greenhouse gasses concerns. So, these light weight vehicles are going to give more mileage with the same amount of energy compared to regular vehicles. However, the challenge

New Era For Automotive Remanufacturing

In conjunction with major organizations representing the international automotive remanufacturing industry, APRA has joined to agree on common and fundamental definitions for essential terms related to remanufacturing, following a meeting in Frankfurt, Germany on September 13th, 2016. Below are the agreed-upon definitions:

REMANUFACTURING PROCESS:

•    Remanufacturing is a standardized industrial process* by which cores are returned to same-as-new, or better, condition and performance. The process is in line with specific technical specifications, including engineering, quality and testing standards. The process yields fully warranted products.
*An industrial process is an established process, which is fully documented, and capable to fulfill the requirements established by the remanufacturer.

CORE:

•    A core is a previously sold, worn or non-functional product or part, intended for the remanufacturing process. During reverse logistics, a core is protected, handled and identified for remanufacturing to avoid damage and to preserve its value. A core is not waste or scrap and is not intended to be reused before remanufacturing.

European associations have further agreed to the following definition:

REMANUFACTURED PART

•    A remanufactured part fulfills a function which is at least equivalent compared to the original part. It is restored

Car Market Brings In Recession Fears

The world is in a pitiful state in the wrap of debts and deflationary forces.

It has been a crucial year for Australia’s once extremely booming car industry. A series of bad news for the Australian car market: last May Ford had announced its decision to shut down all manufacture in Australia, and next in line was General Motors in December to announce the same.

Toyota, will gradually shut down its assembly lines by 2017 emphasizing that the slow death of car manufactures in Australia could be a sign of warning for an impending recession. Toyota revealed that is was heartbroken to initiate a shutdown in the southern state of Victoria while condemning the Australian dollar for its rigidity.

Around 2,500 Toyota workers will lose their jobs. The economic impact however will be much far-fetched than can be imagined at the moment with a huge unemployment rate in the automotive supply sector and even farther than that. This can completely wipe off AU$21bn (US$19bn) from the national economy, leaving as many as 2000,000 jobs at risk: even sectors from transport, logistics and other business services.

How to defuse hackers

Technology can often have its own disadvantages: vulnerability to cyber threats and of course hackers is definitely one of them. This has begun to apply to car technologies as well. Vehicle security is crucial and car companies want to ensure that hackers are kept away from their customers.

Tesla Motors in this respect has begun hiring the best hackers in the industry who will be outperforming ones who are not the best hackers in the respective industry. This means that hackers not related to the automotive industry, will not be able to crack codes easily, anymore. The recent programming conference attended by the company (Def Con security conference) in Las Vegas, Nevada, USA was in line with its hacker recruit. Kristin Page, Tesla’s security expert, recruited the automotive industry’s best talent. He was inclined to employ binary code-adroit tech experts.

There arises a possible question as to why is Tesla losing its sleep over this?

Two incidents sparked off such aggressive hire.

In the first case, a Model S owner was able to crack into his own car’s systems and access a non-standardized web browser on the car’s large, 17 inch display central screen.

Caution Needed Say IDTechEx Analysts

Launches of fuel cell cars are reportedly planned by up to six carmakers from 2015 including Tata Motors of India, owners of Jaguar Land Rover. They are portrayed as pivotal in creating success for pure electric cars but the truth is very different. More is explained in the IDTechEx report Future Technology for Hybrid and Pure Electric Cars 2015-2025.
Toyota has been the first to declare its hand with full details of its contribution the Mirai. People listen to Toyota because it is way ahead as leader in EVs overall with sales about four times those of number two according to analysts IDTechEx. It was right to say that affordable pure-electric cars using batteries were not ready for prime time and right to persevere with hybrids. It knows about pure electric vehicles: it is global leader in pure electric forklifts.
However, Toyota is wrongly reported as “betting the shop” on fuel cell cars. Indeed, a managing director of Toyota Satoshi Ogiso has joked that their Chairman Mr Takeshi Uchiyamada, who was behind the hugely successful Prius hybrid during its ten wilderness years and is behind their fuel cells, is now a Don

Transmission Control Units

Modern day cars are offered with both Automatic and Manual Transmission as per the customer choice. In comparison to manual transmission, automatic transmissions enhance the driving comfort and also fuel efficient as it independently determines the point where engines run most efficiently. There are various aspects to discuss about the Advancement of Technology in Transmission Control Units.

Going High-tech: Modern Transmission Control Units are designed to meet high precision digital intelligence in order to find out engine’s ideal operating point, the control unit posses high-tech computer enabling complex operation of various kinds of automatic transmission systems.  The processing speed of a modern transmission unit is incredibly faster than the computers used in the lunar mission.

Conventional Automatic: A conventional automatic transmission uses various programs stored in the control unit to shift the gears. Most of cars are equipped with a switch strategically placed on the steering helping the drivers to shift gears avoiding errors and adds precision transmission power. Most common conventional transmission is designed with 6 gears though some ultra-efficient versions are designed with 9 gears.

Automated Manual Transmission: An Automated Manual Transmission, abbreviated as AMT, is a combination of manual and automatic transmission.

The Next Thing In Automobile Industry

Google’s self-governing auto program has a tendency to stand out just enough to be noticed when examining the tech monster’s auto activities. Anyway hiding out of sight is a more prompt extend that can possibly at long last “disturb” (as Silicon Valley sorts are so attached to stating) online auto deals.

The last gathering to endeavor such a deed was Truecar, an imaginative and well meaning-organization that eventually ran afoul of merchants, controllers and the Oems. Truecar was compelled to force itself back from the verge and re-concoct itself as a more merchant-accommodating organization.

What Truecar did was mutilate the data asymmetry that auto merchants depend on to profit. Truecar could give information on everything from merchant receipt to transaction costs and permitted merchants to contend with each one in turn for a deal – a significant forbidden in the realm of auto deals.

Presently, Google is taking off an administration, the creatively named Google Cars, past its beginning Bay Area test business sector. Purchasers will have the capacity to log onto Google Cars and utilize the helpful one-stop channel box (as opposed to navigating different menus and sub-menus
