<p>A decompression mechanism for cylinders of motor vehicle comprises a decompression shaft (1), a decompression arm (3) connected with the decompression shaft, and a power supply (13) connected with the decompression arm through a decompression control circuit and a decompression solenoid valve (4). The decompression control circuit comprises an accelerator pedal control circuit and a normally closed switch (15) connected with a brake pedal (9). One end of the normally closed switch is electrically connected with the power supply, and the other end is connected with the decompression solenoid valve through the accelerator pedal control circuit. The decompression mechanism is used sufficiently, which is opened to force the engine to stop running in a specific state. The inertia of motor vehicle in a running state makes the engine idle in a fuel cut-off and flameout state. The mechanism returns to non-decompression state when normal working is needed. At the same time, the feed system returns to normal working, and the engine can be restored to normal working state again under the driving of the inertia force, the process is repeated, so as to achieve the aim of safety and oil saving.</p> |
