The genset air-cooled cooling system uses air as the cooling medium. The high-speed moving air generated by the fan directly removes the heat of the high-temperature parts, allowing the diesel engine to operate at the optimum temperature. Heat sinks are arranged on the outer wall of the cylinder and the cylinder head to increase the heat dissipation area, and an air hood and a baffle are arranged to properly distribute the cooling air and improve the air utilization rate, so that the cooling effect is more effective and uniform.
The PT fuel system is a patented product of Cummins Engine Company of the United State. Compared with the fuel system of a typical diesel engine, the PT fuel system has its own unique features in composition, structure and working principle.
When the diesel engine starts, the crankshaft does not turn or rotate slowly when it rotates, so that the diesel engine can not enter the self-operating state. There are generally three reasons. Firstly, the battery is insufficient, the starting resistance is tool large, or the movable contact and the static contact of the electromagnetic switch are burned. Secondly, poor contact. Thirdly, the specific inspection methods are as follow:
The DC motor is the motive force of the output torque, and most of its structures use a four-pole series-excited motor. Such a motor has a large output torque at a low speed and a strong overload capability.
