n any case, the internal combustion engine is an extremely great invention. It is still the most efficient machine for converting fossil fuels into power demand. Even if the motor has a wider use scene, it does not mean that the internal combustion engine will die. There is also a strong vitality, no longer improving the internal combustion engine technology is very short-sighted.
In recent years, discussions on the ban on the sale of fuel vehicles have been rampant. Although the schedule of most of the current fuel-ban vehicles is in the discussion stage, we have already seen that electrification has become an unstoppable trend in the development of automobiles. Under such circumstances, we are puzzled: Has the internal combustion engine technology we are familiar with has reached the end of life? Will the internal combustion engine disappear completely in the future? From the perspective of some of the internal combustion engine technologies used in production cars in 2018, "traditional internal combustion engine technology is still promising."

Undoubtedly, the degree of electrification of transportation vehicles will be significantly improved in the future, but in the next few decades, most of them will be in the form of hybrid power, that is, a small battery, plus a motor working with a combined internal combustion engine, combined with other Some technologies, such as brake energy recovery, reduce the fuel consumption of automobiles. At the same time, the combination of new combustion technology with more advanced aftertreatment systems and control systems will further increase the efficiency of internal combustion engines and reduce emissions from internal combustion engines. If the electric energy required for electric vehicles comes from fossil fuels, the greenhouse gas effect caused by using pure electric vehicles may also be worse.
In the face of increasingly stringent emission regulations in China, Toyota THS and Honda i-MMD have “mixed” winds and waters, even if the personality such as Mazda also shows the blue sky of Chuangchi, and as one of the three Japanese masters, and "The name of Nissan has made no achievements." As a result, Nissan showed its own killer, VC-Turbo, as the car was switched from a pure engine to a hybrid or new energy source. Nissan understands that if the engine is not taken out again, it will be outdated.
VC-Turbo is a variable compression ratio turbocharged engine. As its name suggests, the core technology is variable compression ratio. In fact, before the Saab, Porsche, and Toyota manufacturers have developed variable compression ratio technology, but due to the low reliability of the technology, high cost and can not mass production, or did not achieve a technical breakthrough, In the end, there was no real success. After more than 20 years of research, Nissan finally successfully launched the first truly mass-produced variable compression ratio turbocharged engine, the 2.0L VC-Turbo engine.
