1. What is an excavator engine block? The excavator engine block is the skeleton of the engine and serves as the assembly base for the crankshaft, connecting rod mechanism, valve train, and other major components of the engine systems. The diesel engine cylinder block is a crucial component of your excavator engine, often overlooked until…

 (Take an electronically controlled common rail system as an example) High-pressure fuel supply The high-pressure pump pressurizes the fuel and sends it to the common rail pipe. The injector is connected to the common rail through the fuel pipe and remains in a high-pressure state, ready for injection. 2. ECU control signal The ECU calculates…

The Cummins diesel fuel injector is the core component in the diesel engine fuel system, responsible for injecting high-pressure fuel into the combustion chamber in the form of precise timing, amount, and atomization, which directly affects the engine's combustion efficiency, power output, and emission level. What does a diesel fuel injector do? 1. Fuel Atomization…

Its operating principle primarily involves the following key steps: 1. Exhaust gas drives the turbine. The exhaust gases emitted by the engine possess inertial momentum, which propels the turbine to rotate. 2. The turbine drives the impeller. The rotation of the turbine drives the coaxial impeller, which compresses the air supplied through the air filter pipe,…
