Basic Concept of Diesel Engine in Cummins Diesel Generator Set

Feb. 21, 2023

The diesel engine in Cummins diesel generator set is a kind of power machinery that converts the heat energy generated by the combustion of diesel in the working cylinder into mechanical energy. It mainly consists of cylinder, cylinder head, cylinder sleeve, piston, connecting rod, brain uranium and flywheel. It is composed of intake valve, exhaust valve and fuel injector.

The effects and interrelationship of the above components are as follows: the intake valve is used to suck in fresh air; The exhaust valve is used to clean up the burned exhaust gas in the cylinder, and the fuel injector is used to inject diesel into the cylinder to burn the cylinder head, piston and cylinder sleeve, which form the incineration air; One end (small end) of the connecting rod is connected with the piston, and the other end (large end) is connected with the crankshaft. When the gas in the incinerator burns and expands, the y5 will flash down and move, push the sleeve through the connecting rod to rotate, and vice versa. The inertia force of the crankshaft and flywheel rolling together can also push the piston up and down through the connecting rod. In this way, the reciprocating movement of piston - k and down constitutes the basic condition for the diesel engine operation cycle in Cummins diesel generator set.


When the diesel engine in Cummins diesel generator set operates, the piston moves to the uppermost position of the cylinder, which is called - L dead center; Move to position 2 at the lowest end of the cylinder, which is called the bottom dead center. The interval between top and bottom dead centers is called piston stroke (also called stroke). One stroke of the piston is equal to 1: twice the rotation radius of the crankshaft. Every time the piston moves one stroke, the bending rivet rotates for half a cycle.


When the piston is at the top dead center, the volume of the cylinder above the piston top is called the volume of the combustion chamber. When the piston reaches the dead center, the cylinder volume above the piston top is called the total cylinder volume. The value obtained by the total volume of the cylinder and the volume of the incinerator is called the compression ratio, which indicates the degree of gas compression in the cylinder. The greater the compression ratio, the more fierce the gas compression in the cylinder.


Starlight Power has advanced testing equipment, modern production technology, professional manufacturing technology, perfect quality management system, and strong technical research and development capabilities. It can provide 3KW~2500KW various specifications of ordinary, automatic, four protection, automatic switching, low noise and mobile generator sets, high quality and low energy consumption to meet the diverse power needs of customers, and can also meet users with different voltages and different frequencies. It is required to create a parallel power supply system for multiple units. If you are interested in our product or any question on generator, welcome to send email to sales@dieselgeneratortech.com.
