Advantages:
the advantages of diesel engine is low fuel consumption, high reliability, long life, high twist. Diesel engines emit much less harmful gases (especially less CO) than petrol engines, so they are environmentally friendly compared to petrol engines.
Disadvantages:
lower speed than gasoline engine (general speed of 1800-3000r /MIN), large quality, high manufacturing and maintenance costs, noise, start difficult, etc. And diesel vehicles often drive on the highway, the vehicle for a long time, the engine temperature and pressure are high, the cylinder produces more soot and carbon deposition, engine oil is easy to oxidize to produce colloid, so the diesel engine oil requirements have good high temperature cleanness.
Resources:
Diesel engine is widely used and is in the relative core position of its industrial chain. In the past ten years of development, the diesel engine production industry has formed a series of supporting enterprises, many diesel engine enterprises more as the general bearing assembly role, and some of the key components of the diesel engine: crank connecting rod, piston, cylinder liner, CAM has been produced by professional companies. The specialized division of labor enables the diesel engine manufacturers to concentrate on their own advantages and focus on the design and manufacture of diesel engines.
Diesel engine is mainly used for final supporting products, such as high-power high-speed diesel engine is mainly used for heavy-duty vehicles, large buses, construction machinery, ships, generator sets, etc. Therefore, the development of the diesel engine industry depends to a large extent on the relevant end product market conditions.
