Loader accessories mainly produce various specifications of hydraulic transmission Hydraulic torque converter, torque converter accessories and other loader accessories. Now let's introduce the structure of loader engine:
??1. During the intake process, the crankshaft rotates and the piston moves from top to bottom. At this time, the intake valve has been opened. As the piston moves downward, the volume above the piston increases, generating vacuum suction. The fuel and air are atomized and mixed into a combustible mixture through the carburetor and sucked into the cylinder through the inlet valve. After the piston reaches the bottom dead center, the intake valve closes and the intake stroke ends.

??2. Working stroke. When the compression stroke piston approaches the top dead center, an electric spark is generated between the spark plug electrodes to ignite the compressed combustible mixture, and the burning gas expands rapidly, making the instantaneous pressure in the cylinder reach 2940kpa-4410kpa and the temperature reach 1800 ℃ -2000 ℃. Under the action of high-pressure gas, the piston is forced to move from the top dead center to the bottom dead center. The thrust of high-pressure gas is transmitted to the crankshaft through the connecting rod to make it rotate, so as to convert heat energy into mechanical energy.
??3. Exhaust stroke. At the end of the working stroke, when the piston is pushed close to the bottom dead center, the exhaust valve opens and the piston moves upward from the bottom dead center. Driven by the piston, the exhaust gas burned in the cylinder is discharged from the cylinder through the exhaust valve. After the piston reaches the top dead center, the exhaust valve closes and the stroke ends.
