The fuel injection pump (also known as the high-pressure fuel pump) of a bulldozer engine is the core component of the diesel engine's fuel supply system. Its core function can be summarized as: pressurizing fuel to extremely high pressure at precise times and delivering a measured amount to the fuel injectors. The bulldozer engine fuel injection pump is the core component of the fuel system, responsible for precisely injecting pressurized fuel into the cylinders.
High-Pressure Pressurization: Pressurizes low-pressure fuel (from the fuel pump) to 100~250 MPa (approximately 1000~2500 times atmospheric pressure), enabling the fuel to be atomized at high speed and injected into the cylinders.
Precise Timing: Through camshaft linkage, fuel injection begins precisely before the piston's top dead center during compression, ensuring combustion efficiency.
Fuel Quantity Control: Dynamically adjusts the fuel supply according to engine load (such as bulldozing or climbing hills), controlled by the throttle or ECU (electronic control unit).
