Diesel engines have significant advantages of high thermal efficiency, and their application range is becoming wider and wider.
As the degree of strengthening increases, the weight per unit power of the diesel engine is also significantly reduced. In order to save energy, countries are focusing on improving the combustion process and studying the use of low-quality fuel oil and non-petroleum products.
In addition, reducing friction loss, widely adopting exhaust gas turbocharging and increasing the degree of supercharging, further lightening, high speed, low fuel consumption, low noise and low pollution are all important development directions for diesel engines.
