What is a big pump engine
In the fields of automobiles and construction machinery, large pump engines have attracted much attention due to their excellent power performance and reliability. This article will introduce in detail the definition, working principle, characteristics and application scenarios of large pump engines, and provide you with a comprehensive analysis based on hot topics and hot content in the past 10 days.
1. Definition of large pump engine
Large pump engine, the full name of "large flow fuel injection pump engine", is a diesel engine using high-pressure fuel injection technology. Its core component is a high-pressure fuel pump, which can inject fuel into the cylinder at extremely high pressure, thereby achieving more complete combustion and higher power output.
2. Working principle of large pump engine
The large-pump engine pressurizes the fuel to more than 1000bar through a high-pressure fuel pump, and then atomizes the fuel through the injector and injects it into the cylinder. This high-pressure injection technology can significantly improve fuel combustion efficiency, reduce emissions, and increase engine torque and power.
3. Characteristics of large pump engines
The large pump engine has the following salient features:
| Features | describe |
|---|---|
| High power output | High-pressure injection technology enables more complete fuel combustion and stronger power |
| low emissions | High combustion efficiency and cleaner exhaust emissions |
| High reliability | Simple structure, low failure rate, suitable for harsh working conditions |
| Low maintenance cost | Long service life and low maintenance frequency |
4. Application scenarios of large pump engines
