1. Fuel characteristics:
Diesel: high viscosity, poor volatility, good self-ignition
Gasoline: low viscosity, good volatility, higher ignition point than diesel
2. Fuel supply system:
Diesel engine: The traditional one is the fuel injection system, also known as the pump nozzle system.
The structure of the fuel injection system of a diesel engine is more complex than that of a gasoline engine. The high-pressure oil pump requires a set of drive mechanisms to drive it, and it must be equipped with a set of speed regulating mechanisms.
Many modern diesel engines use high-pressure common rail electronic control systems and single pump electronic control systems-Gasoline engines: Gasoline engines mainly use carburetor fuel supply systems; modern gasoline engines draw on the advantages of direct injection diesel engines and use more electronic injection systems (divided into intake port injection and cylinder injection)
3. Air-fuel ratio:
Diesel engine: There is only one situation for the air-fuel ratio of a diesel engine: >1:, diesel engines can achieve high-pressure intercooling technology, and electronic control is easier to achieve than gasoline engines. Therefore, it has significant characteristics and advantages such as high power per liter, strong power, more complete combustion, good economy, and low emissions.
Gasoline engine: There are three states of air-fuel ratio in gasoline engine: 1-. or =1; or <1. Gasoline engine power and economy are relatively low, and the exhaust emission control technology requirements are higher and more difficult.
Gasoline engine has its own characteristics compared with diesel engine; gasoline engine has low speed, low noise, easy starting, and low manufacturing cost; diesel engine has high compression ratio, high thermal efficiency, and better economic performance and emission performance than gasoline engine. These are the significant advantages of diesel engine.
