3.1 Diesel is a relatively high thermal efficiency of power machinery

Diesel fuel injection with high-pressure, high-frequency, pulse and other characteristics. Its injection pressure of up to 200 MPa, for the gasoline engine jet pressure of more than 100 times. High-pressure fuel injection system for the implementation of electronic fuel injection control, much more difficult. Diesel and jet spray is on the high accuracy, compared to only point on the Detroit Diesel the perspective of location accuracy requirements than the gasoline engine, which led to a diesel injection for the implementation of the electronic control much more complex.

3.2 As the diesel injection system in various forms

Inline with the traditional diesel engine pumps, distribution pumps, fuel injection pump, single-cylinder pumps, and other structures completely different system. The implementation of electronic control technology is more complicated the implementation agency, formed a diesel injection system of diversification at the same time the need for diesel fuel, timing, injection pressure, and other parameters of a comprehensive control, the difficulty of its software is also greater than gasoline engines.
