In Japan many years ago, the horsepower of civilian cars was limited to less than 280 horsepower. At the same time, the road conditions in Japan determined that there was no need for such a strong power output. The Japanese used more of their minds to build quiet and comfortable civilian vehicles. Turbocharged technology is more used in sports racing cars. There are not so many supercharged civilian cars. This has caused the illusion that Japanese cars are not turbocharged.
In fact, Japan's modified vehicles are basically turbocharged. Japanese automakers do not lack turbocharger technology. Of course, this is not a Japanese predecessor's prejudice against the Chinese market. Looking at the product lines of several major Japanese brands in the world, whether it is Toyota, or Honda, even the high-end brands they are trying to build, there are also few turbo models.
In addition to the 660cc Turbo mini-car, and the Subaru R2 still sold in Japan, the SUVs such as the Acura RDX, which is equipped with turbocharged engines, are considered heterogeneous. This is in sharp contrast with the European cars that nowadays prefer to make a fuss about the turbo. Contrast.
In fact, as most fans know, there is no shortage of turbocharger technology in Japanese automakers. As early as the 1980s, turbocharged engines have become popular in Japanese cars in the face of fierce market competition at the time. Not only was the 'God of Wars' GTR equipped with the RB26DETT turbocharged engine, but Honda's turbocharged engine was very popular in the F1 field at the time.
Until the 1990s, Toyota's Supra, Mitsubishi's 3000GT and Mazda's RX7 all became the 'boost' star of the time. To this day, not only new generation GTR, Subaru STI, Mitsubishi EVO these load turbines increase the Japanese performance of the engine. The car is praiseworthy. Nowadays, many European cars are equipped with Japanese turbines.
Now you may feel that some auto parts, like spark plugs and the like, are better to use Bosch. Actually, before Bosch there was a brand called DENSO (Nippon Denso), which has wider coverage than Bosch now, and is used by manufacturers all over the world. Earlier 70% of the accessories of many domestic brand cars were provided by Japan, so we also advise everyone that if the situation in Japan is strained on someday, don't go to the road and pick up a Japanese car. Pull off your spark plug first. Look at what brand. (I really think that the quality of domestic cars is so reliable?)
The concept of differential manufacturing determines the positioning of the product. Why domestic turbochargers are not found in Japanese cars? In fact, as long as we look at the valve technology that is continuously promoted by domestic Japanese cars, it is not difficult to see that they prefer to use natural suction and valve technology. The article, as Honda believes, has advanced supercharged engine technology, but Honda is more willing to perfect naturally aspirated engines than consumers who buy Honda cars. Said that Honda's current naturally aspirated engines can meet their demand for power.
Honda’s claim is not surprising. It is also determined by the positioning of Honda’s products. Toyota, which focuses on product quality and cost control, has a similar view to Honda. Toyota believes that turbocharged engines are achieving fuel economy and environmental protection. There are not many advantages, and the production cost and use cost are higher than naturally aspirated engines. Toyota's naturally aspirated engines with VVT-i technology can also meet the needs of most users, and compared to the same displacement. Supercharged engine fuel economy is even better.
Mazda advocating handling performance also believes that the naturally aspirated engine in vehicles other than the RX8 can also have good power performance, and is easier to maintain and maintain. Knowing Japanese car manufacturers' family cars and high-performance cars have a clear concept It is not difficult to see that even Subaru and Mitsubishi, which have mastered turbocharging technology, will only use turbocharged engines on high-performance models to compete with large-displacement natural inhalers.
No matter how Japanese car manufacturers are facing the coldness of today's Chinese automobile market for turbos, the pursuit of high-performance cars by the Chinese people has remained the same and has become increasingly fierce. Turbocharged engines have passed the lukewarm period of 10 years and are hot under the pressure of promoting environmental protection. It's not just in China.
With the continuous development of turbo technology, such as the development of needle roller bearings and new cooling technologies, the high failure rate of turbochargers has ceased to exist and the life span has exceeded 150,000 kilometers. Many cars no longer have to deliberately observe The use of 'turbine cars' is annoying. However, today's turbocharged engines still require special care compared to ordinary naturally aspirated engines, such as higher quality synthetic motor oil, higher grade gasoline such as 97 or 98. # and more stringent maintenance intervals.
However, these are no different from the same high-performance naturally aspirated engines. High-grade fuel and high-quality gasoline are also their necessities. It seems that whether they are naturally aspirated or turbocharged, they must enjoy high performance. Fun, there will be more to pay. Today's turbochargers no longer have a terrible delay, lighter and lower turbocharged turbines, VGT (variable section turbocharger system) turbines, and dual swirl intake technology The appearance of the turbocharged engines will make the turbocharged engines smoother and smoother. Even if you deliberately experience them, it will be difficult to detect their presence.
The Japanese believe that turbocharged engines do not have much advantage in fuel economy and environmental protection, and they are more expensive than naturally aspirated vehicles in terms of auto production development costs and consumer maintenance costs. Data show that naturally aspirated engine service life Can reach 15-20 years. The turbocharged engine is only 10 years -15 years, and the turbocharged system of the car turbine is a fragile part.
Therefore, regardless of the protection of product quality or the environment, the natural use of resources to inhale is more advantageous than turbocharged. Under the temptation of interest, Japanese man-made vehicles can remain calm and restraint, have to admire. Just in China, Japanese cars have found that if they do not keep up with the trend of turbos, they may be eliminated by the market and have to develop their turbocharged models.
If you have been to Japan, you will find that all kinds of K-Cars with a capacity less than 660 cc are visible everywhere in Japan. There are no shortages of all kinds of K-Cars with yellow license plates, small size, and even a variety of 'sprouting' types. Lightweight cars, especially when they are on the streets, you will deeply feel the special love and love of the people of the island nation for the car.
Japan is an island nation. The small size of the property determines the relative lack of a realistic environment for its ecological resources. Second, Japanese society has already passed the era of “showing off the wealth of cars” (Japan experienced the past in the 1970s and 1980s). Today's Japanese, especially the Japanese younger generation, have a poor car buying enthusiasm, and their public transportation system is well developed. Private cars are not a necessity for daily life. The more economical they are, the more practical and better. Therefore, the durability and economy of naturally aspirated engines are irreplaceable. of.
