Japanese cars are very popular in our country, so why don't many Japanese cars use turbo technology? Even if there is, why are they mostly subcompact models?
Actually, many people don't know much about turbocharging. They just say that turbocharged cars are better. Many people have some misunderstanding about this. So what are benefits of turbocharging? Let's compare 1.5L and 1.5T engines. In terms of power, if same model is equipped with two different types of engines, turbocharged engine is stronger than naturally aspirated engine. Turbo power output is about 40%, or even slightly more. In addition, it can improve fuel economy and reduce emissions. It can be said that turbocharging has function of reusing exhaust gases.
A very understanding person asked why Japanese cars rarely use turbocharging? Firstly, service life of a naturally aspirated engine is longer than that of a turbocharged one, generally speaking, in normal operation, life of a self-priming engine is 15-20 years, and a turbocharged engine is 10-20 years. 15 years. Why is it so? Since turbocharging method results in a higher combustion temperature in engine, service life is naturally not as high as that of a naturally aspirated engine. And basically, in many models, spontaneous combustion now occurs, which is also caused by engine overheating.
In addition, maintenance cost of turbocharged engines is slightly higher, which can be seen as a relatively delicate condition. same service life, and direct injection into cylinder forms deposits more easily,
The smoothness of turbocharging is not as smooth as natural suction. Beginner drivers and friends are advised to consider this more when buying a car. , because handling is relatively not as good as natural aspiration, and low-end torque is not strong enough.
Many people think that a 1.5T turbocharger can reduce fuel consumption because it can recycle exhaust gases, but this is not true. A 1.5T engine is equivalent to a 1.8L naturally aspirated engine. It is not very economical when driving at high speed, but stronger in terms of acceleration. How much power is applied and how much food is eaten is a law of physics that cannot be changed. So will it save fuel in traffic jams? In fact, it's all same reason.
For many car owners nowadays, if they drive around city, their personal opinion is that natural drive will bring better economic conditions. If it is mountain climbing and swamp, turbocharging is also a good choice. You still have to choose right engine for you in accordance with your personal conditions.
