Most of the domestic automobile plant joint venture, with technology from the foreign decision-making power, the use of electronic products to provide more complete by the foreign and domestic self-developed electronic products is difficult to enter their complete system, which seriously affected the domestic automotive electronics industry. China’s opportunities for China’s accession to WTO, will gradually lift the localization of car-assembly requirements, to achieve global procurement of parts cars. In this backdrop, but also for the development of China’s automotive electronics industry has provided new opportunities and challenges. Automotive electronics industry as an emerging industry groups, its market growth potential.

According to the data to forecast that by 2005, China’s automotive electronics industry’s annual output value will reach more than 2000 billion, which is currently the largest increment of the product categories, we can see the development of automotive electronics industry has become essential. Through the research of China’s automotive electronics industry, China Electronic Information Industry Development Research Institute, Tsinghua University and other experts believe that as long as the active tracking of foreign advanced automotive electronic technology, as soon as possible to shorten our country and foreign advanced automotive electronic technology gap, China’s automotive electronics industry is promising. To this end, the experts put forward the development of China’s automotive electronics technology, a few proposals.

The first is to develop the promotion of policies to encourage the development of automotive electronics. Proposed to use discount loans in support of industrial engineering and technological transformation of enterprises; recommended the establishment of Automotive Electronics and Control Engineering Research Center, focusing on the electronic control unit hardware and software research, part of which is the foreign companies will not carry out the transfer of technology; to attract domestic small and medium sized e-business engaged in the business performance of automotive sensors, automotive electronic control actuators of the introduction, development and production. Ic-known to use foreign companies to conduct car business performance CPU’s OEM design and manufacturing; organization or to create automotive electronic control system integration enterprises.

The second is to strengthen macro-control, to avoid the research and the introduction of duplication and waste.

Third, make full use of the introduction of vehicle technology, digesting and absorbing assembly with the vehicle or the introduction of electronic technology. At present, China has introduced a variety of cars and engine technology. They are equipped with varying degrees of advanced electronic products, such as electronic injection devices, anti-lock braking system, etc. There are also a few companies have a separate introduction of this technology; we should lose no time in the Organization’s technical strength of these technologies digest absorption, innovation, and gradually realize localization; the same time to make use of foreign advanced technology, enhanced development capabilities, shorten our application of electronic technology in the automotive process.

The fourth is to develop more stringent, but also for China’s national conditions fuel consumption, emissions and safety standards, and vigorously promote the adoption of legislation on information technology in the automotive applications, there must be corresponding support policies and regulations, such as the development of environmental regulations, safety regulations, and fuel economy regulations.

The fifth is to establish a research and development capability to have independent team and a group of scientific research base, increase investment in research funds; actively track the foreign advanced automotive electronic technology, to shorten the China and foreign advanced automotive electronic technology gap. Sixth state loan deal with automotive electronics projects, products, preferential policies in taxation. Automotive electronics industry will play an important role in people of insight have recognized the development of the automobile industry, there must be the rapid development of auto parts industry, as a support, to promote the rapid development of China’s auto industry, and thus enhance its competitiveness in the international market force.

In the auto parts industry development, the automotive electronics industry will play an important role. This role is mainly reflected in the following aspects: First, for the automotive industry to provide technical support for the upgrade. Now the car has begun to abandon the mechanical concept of the future will be replaced by integrated electronic modules, automotive electronic devices will become. The second is to improve vehicle performance and low cost.

The automobile industry has massively evolved since the invention of the first steam engine in the 1700s. Automobiles have gone a long way in terms of speed, design and function. On top of all that, the car manufacturing industry also ventured into engineering a more safe car design for people.

The call for more sophisticated car designs in terms of safety and security rose when car velocity constantly increased through time. Add to this the disturbing accident rate caused by reckless driving. Currently, though, Ajax car dealers can attest that car safety technology proves to be rapidly improving. In fact, the concept that constitutes car safety has changed fundamentally.

Before, seatbelts defined passive car safety technology, which paved the way for the creation of active safety measures.

Passive technology highlights safety by reacting to the accident, while active measures aim at preventing the accident. Active car safety technology harnesses the power of advanced computer intelligence and the car-based radar system. These components make it possible for most drivers to do quickly decide before the accident happens. Others just cannot care less while some critics argue that the sophisticated car technology makes for more lazy and aggressive drivers. However, such critics will not stop the automobile industry from developing more safety features for drivers.

Subsequently, one of these new car safety technologies includes Electronic Stability Control (ESC). The anti-lock braking systems required in most vehicles now, inspired the creation of ESC.

This interesting new technology ensures the safety of the vehicle with its capacity to sense and reduce slips. Auto Durham specialists can attest that ESC detects loss of steering control and automatically applies the breaks to help steer the car where the driver wants it to go. Breaks are automatically applied to individual wheels: outer front wheels to counter over steering and the inner rear wheels to under steer, whichever is applicable under such circumstances.

Moreover, another sophisticated technology developed is the Distance Control System. This concept borrows from the existing technology of collision warning, but outsmarts it. Unlike its predecessor, it highly works on preventing accidents from taking place. This electronic system helps drivers limit the distance between their car and the object in front. The system intelligently determines the distance of the car in front and computes for the speed of both cars by using a radar sensor attached to the car’s façade.

Lastly, an existing technology uses an integrated system of cameras that guide drivers if their cars are out of lane. It is popularly known as Lane Departure Warning System designed to alert the driver and passengers that the car is moving out of its current lane on the road. This highly sophisticated system, which some Ajax Chrysler models have, aims to reduce accident rate by dealing with the main cause of collisions: human error.

Contemporary large functionality engines necessitate cylinder heads that offer precise operation to keep up the essential operating speeds. The heads cylinder configuration has turn out to be a technological marvel on modern day engines. This is actually a departure in the earliest flat head engines exactly where the head was straightforward piece of flat steel that was bolted on top rated of your cast iron prevent. The earliest heads simply just sealed inside internal transferring elements and helped discover when repairs and routine company had been required. Flat mind engines have been basic and straightforward to function on but a smaller amount efficient to function.

Advances in performance led to such variations as the overhead valve cylinder heads along with the overhead cam heads. They’re however well-known currently and could be identified on nearly every engine. An overhead valve head and cylinder configuration keeps the valves in the mind. The valves are accountable for permitting the fuel mixture to achieve the cylinders and the exhaust gases to be evacuated through the cylinders. The valves will seal shut through operation to let combustion in every cylinder to acquire site. Overhead cam cylinder heads consist of the cam shaft mechanism that operates the valves. With overhead cams you will discover significant components including connecting rods needed. This creates a additional successful engine. Overhead cam engines also let for contemporary advances including cylinder deactivation and shutdown on avoid engines that conserve fuel by only using the motor in the event the automobile is in fact shifting.

As know-how has highly developed the head cylinder configuration continues to be modified several instances. Cylinder heads now include cams that have various profiles and design and style. The heads will handle the operation from the engine through laptop programs that might deactivate cylinders as soon as operating speeds have been reached. The heads cylinder deactivation systems will shut away from two or much more cylinders permitting the motor to function additional efficiently. When higher ability is essential the cyl heads will activate the cylinders by operating the valves that had been disabled. This will likely allow in fuel and discharge exhaust and dissipate warmth.

Since the head functions being a cover to the motor block the seal in between head cylinder has to get restricted and full to do away with leaking. For the reason that head and cylinder have oil and normal water operating through them the seal have to be impenetrable also. Any mixing of coolant and drinking water will probably be extremely damaging for the internal components of an engine. Internal combustion engines have can come a long way considering that they ended up being very first invented inside the late 1800s. Contemporary cylinder heads let motor technological innovation to be much far more sophisticated than was previously believed feasible.

In fact, you really should have a good idea of what is contained under the hood of a car otherwise you won’t have a good idea of whether is an ideal match for you driving needs.

Heat Treatment Technology in Automotive Bearings

Bearing, which is widely used in machinery industries, is an important basis for mechanical connections. It is said that when there is rotation, there is a bearing. At the same time, as a main means of transport, car plays a significant role in our daily life. Thus, the automobile industry also becomes a pillar industry in China where bearings play an important role. Bearing products can be seen in many security devices of cars such as the steering gear, engine and gearbox, etc. As a branch of bearing category, the automotive bearings have many special properties such as high-speed rotation and shock resistance which have great effect on passengers, drivers and safety of the vehicle itself.

Heat treatment is a key process during the manufacturing process of the automotive bearings.

Its processing quality and the quality of raw materials are two important factors that affect the bearing life. The following is a brief introduction of the heat treatment technology on the car bearings. The introduction will lay basis on the automotive bearing materials, heat treatment design, heat treatment equipment, heat treatment technology and the development trends of the heat treatment, etc. Let us see some of them.

The quality of the bearings is the most important factor that determines the service life of the bearing products. The material is the main reason for the gap between China’s automotive bearings and that of foreign countries. Besides, the bearing design, process level and process equipment are other factors. Although China has proposed many useful standards, full implementation is still very difficult because we subject to many elements like domestic steel smelting technology and costs.

With the extensive application of vacuum degassing, the control of the oxygen content of our bearing steels has greatly improved which is close to foreign standards.

However, there is still a large gap in the uniformity of carbide, and carbide network control. All of them lead to the imperfection of domestic automotive bearings. As a result, the service life, reliability, and consistency of bearings are inferior to foreign bearings.

There is also a lack of differential designs. Advanced bearing design should be based on the bearing service environments so as to meet the requirements of the actual condition of bearings. Domestic individual and differential bearing design is still insufficient. In addition, heat treatment of bearing design is also an important factor that affects bearing life. Bearing includes four main pieces. There are outer ring, inner ring, rolling element and cage. Foreign bearing companies have special hardness requirements for the outer race and rolling elements of bearing products. But there is still a restriction on the hardness design of the bearings.
