HOW TO

The hydraulic system is the core component of the excavator, which works to control the transmission shift, fan cooling, boom floating, pilot oil source, and various attachment. The failure of the hydraulic...

2. Common rail technology   In automobile diesel engines, the high-speed operation makes the diesel injection process only a few thousandths of a second. Experiments have shown that the pressure...

Cumbersome, noisy, and spraying black smoke, many people have a bad impression of diesel engines. After years of research and application of new technologies, the status quo of modern diesel...

Pressure loss Due to the viscosity of the liquid and the inevitable frictional force when flowing in the pipeline, the liquid must lose some energy during the flow. This part...

The role of the hydraulic system is to increase the force by changing the pressure. A complete hydraulic system consists of five parts, namely power components, actuators, control components, auxiliary...

PCV is the abbreviation of Positive Crankcase Ventilation (forced crankcase ventilation) in English, which means crankcase (or oil pan) active ventilation control system in Chinese. Positive Crankcase Ventilation valve consists...

Main Function When the engine is working, the high-pressure combustible gas mixture and the burned gas in the combustion chamber will more or less leak into the crankcase through the...

The molecular weight of gasoline is small, so the boiling point is only 20-220 °C, but the flash point is above 400 °C. The molecular weight of diesel is large,...

The gasoline engine generally injects gasoline into the intake pipe and mixes it with the air to form a combustible mixture and then enters the cylinder. People usually call it...

The cooling system consists of a cooling water pump, a radiator, a cooling fan, a thermostat, a water temperature sensor, a compensation water bucket, a water jacket in the engine...

1.Diesel Engines in America Diesel engines are not only far ahead of gasoline engines in terms of CO2 emissions, but in the near future fuel will also contain less sulfur...

A thermostat is a valve that controls the coolant flow path. It is an automatic temperature adjustment device, usually containing a temperature sensing component, which turns on and off the...
