Memoirs of Lao Xie, the automobile culture of Taiwan Province Province in 1990s when semiconductor technology soared.

Lao Xie used to make an advertisement for his mobile phone. Technology always comes from human nature. Due to the technical breakthrough of semiconductor IC integrated circuits, the electronic industry in Taiwan Province Province has developed rapidly. From all kinds of practical household appliances, audio-visual entertainment equipment to transportation, there has been a wave of industrial revolution, including, of course, the personal computer PC and the Internet, which have had the greatest impact on human life recently.

Since 1990, the lifestyle of Taiwan Province Province has been greatly influenced by the vigorous development of integrated circuits, PC personal computers, Internet and digital information during the 65,438+00 years, including the research and development technology of automobiles. The 1990s can be said to be a crucial period for the development of refitting in Taiwan Province Province, which experienced a revolutionary period of rapid development of automobile technology.

Automotive electronics are becoming more and more mature.

The development of automobile industry is also closely related to the gradual maturity of electronic system technology, from engine supervision system, automatic transmission control system, ABS anti-lock braking, TCS tracking control system, protective airbag to constant temperature air conditioning or seat electronic control, it is inseparable from integrated circuits.

Small IC boards and chips replace the traditional circuit control system, which has the advantages of quick action and diversified functions, and gradually increases the equipment in the car, providing a more convenient and relaxed driving environment.

Similarly, the engine and transmission system have gradually matured due to the technology of electronic control system. Although the working mode of internal combustion engine is almost the same as the design when 100 was first invented more than a year ago, due to the mature technology and accurate electronic fuel supply and ignition system at that time, variable valve timing control and turbocharging control with very high visibility appeared.

The past of engine management

In the early 1990s, most commercial vehicles were single-convex two-valve engines with two throats carburetor, and only a few advanced vehicles had DOHC with mechanical injection. Four-valve engine. However, since 1993, the DOHC design of EFI has suddenly become popular, and the valve part has also been strengthened, adding a three-way catalytic device to correspond to the regulation of adding unleaded gasoline.

However, the early electronic control, probably only EPROM? Type's 8-bit ECU drives the fuel injector and semi-crystal distributor to ignite synchronously, and there are only wing air flow meters or absolute pressure intake sensors around it, and there are throttle valves and oxygen sensors. Fault diagnosis only depends on instrument inspection or flashing light of ECU itself, which sensor is faulty and looks like 286? Consistent with the PC.

By 1996, the engine performance has reached a key point of rapid development. During this period, vehicles began to appear variable intake manifold and variable valve timing as weapons to enhance intake and exhaust efficiency. The computer has also been changed to 16 with faster execution speed and smaller size? Bit? The CPU has a built-in memory integrated circuit chip, which jointly controls the all-crystal ignition drive of two groups of injectors and two cylinders, and cooperates with hot-wire air flowmeter, camshaft or crankshaft angle sensor and knock sensor to form a complete interpretation. There are more and more projects, and they are becoming more and more exquisite.

Since the carburetor has been completely changed into an electronic injection system, the fuel injection and ignition can be adjusted only by using an auxiliary modified computer. Therefore, after refitting the turbine, the oil supply of a large amount of intake air is instantly corrected, which is no longer a headache, the combustion efficiency and stability are greatly improved, and more horsepower can be brought with less fuel consumption.

At that time, the refitted fuel supply computers in Taiwan Province Province were mostly models with independent sensors and additional nozzles, instead of programmable computers that could be connected in series or independently adjusted for fuel supply ignition, but this was a breakthrough for the refitted industry.

Motor racing in Taiwan Province Province at that time.

Although motor racing in Taiwan Province Province had developed for several years at that time, it remained stagnant, and motor racing activities could only be held in redrawn areas and parking lots covered with telephone poles. Until1992 "tis" circuit (Taiwan Province? International? Taiwan Province Province is a semi-legal racecourse.

However, if we look at the quality of TIS track according to FIA regulations, we can only say that it is very bad. Lack of hardware facilities is the most criticized. The smoothness of the pavement and the paving materials are not perfect, but they are still enjoyable in Taiwan Province Province at that time! After all, this is the only place in Taiwan Province province where you can compete legally. ? In this racing desert of Taiwan Province Province, it is not easy to have such a racing track, let alone how to finish it perfectly.

TIS circuit also makes many drivers enjoy it here, not to mention it has trained so many excellent drivers. From the early Sun Xing, Greta, Gao, Gao, Chen Junshan, Che, etc. , to the Mesozoic,, Qiu Chuanfeng, Jane, are still active today, and have sprung up in China in recent years? GT battles, such as Huang Xizhan and Guo, were all honed by TIS.

The sharp bend is the biggest feature of TIS, which is so difficult that even Japanese masters like Kazuo Shimizu can't completely overcome it in a short time. Therefore, this is definitely a decisive beginning in the racing history of Taiwan Province Province.

Southern folk horse racing

However, at that time, the population that actually participated in the TIS race, including the Marlboro RV race, was about 500. Not all car enthusiasts will take part in the race, especially because TIS track is located in the north of Taiwan Province Province, and many fans in the south are too lazy to transport their cars to the north for 4-5 hours, so there is a so-called Kenting racing tide in the south.

Kenting is an important tourist attraction in Taiwan Province Province. Because there are many high-speed bends and few people except the straight road to this place, many racers like to run around here aboveboard, but the pleasure it brings is completely different from that of the racetrack, which is why many people are trapped.

At that time, the grand occasion of racing in Kenting was not lost to the first word D in Japanese comics, and the method was also very similar. From Kaohsiung Xiaogang Airport to Caesar Hotel in Kenting, whoever has the fastest speed is king, which is called Kenting Cup.

However, it gradually disappeared because the underworld participated in gambling and police raids. Due to the popularization of Kenting Cup, the backward refitting level in southern Taiwan Province Province has also been improved. Many fans who participated in the Kenting Cup at that time are now the owners of famous refit shops in the southern region.

South foreign exchange factory

Besides, Taiwan Province Province is a so-called trade paradise, and the south of Taiwan Province Province is the location of Kaohsiung Port, the largest port in Taiwan Province Province. As we all know, most Japanese engines or the highest series models are not exported to other countries for sale, so a new industry, the so-called foreign exchange factory, has emerged in the modification industry in the south of Taiwan Province Province.

These foreign exchange factories specialize in importing all kinds of Japanese engines of the highest series, and then implanting the low-end models of Taiwan Province Province, such as Civic sold in Taiwan Province Province, only SOHC? 16V 130hp engine, as long as the engine of B 16A or even B 18C is directly implanted, the horsepower can be immediately above 170hp. Moreover, because most engines are imported by Japanese automobile dismantling plants in the name of using waste hardware, the taxes and fees are not high, and they are loved by many car fans, which has gradually caused cultural differences between the north and the south of Taiwan Province Province.

SER in the United States was very popular in the 1990 s because it can be implanted into the turbine engine of SR20DET.
