Electrical interface : 24V DC start, reserved 150kW PTO expansion interface (marine model).
Products Application
Application scenario parameters Marine adaptation : Working principle and core functions of the engine crank-connecting rod mechanism
Energy conversion mechanism
The crank-connecting rod mechanism drives the piston downward through the expansion pressure of the gas in the combustion chamber, converts thermal energy into mechanical energy, and outputs power in the form of crankshaft torque. This process involves the step-by-step transmission of gas pressure → piston reciprocating force → crankshaft rotational force.
The linear reciprocating motion of the piston is transmitted to the crankshaft through the connecting rod, and is converted into continuous rotational motion through the eccentric structure of the crankshaft, realizing the two-way conversion of linear motion and rotational motion.
Application scenarios
Transportation sector
Automotive power system
Automotive engines are divided into diesel engines, gasoline engines, electric motors and hybrid power according to the power type to meet the needs of different models.
Ship power
Carter large engines and Perkins 1104D series provide ships with high-torque, low-fuel-consumption diesel power to meet the needs of ocean voyages and special operations.
