Combustion engine hand lever starting counter-rotation proof apparatus

Abstract

The invention relates to the internal combustion engine handle starting non-reverse device, which relates to the technical field of internal combustion engines. It provides a safety device for starting an internal combustion engine handle, which is composed of a generator, a main circuit manual switch, a relay, a control circuit manual switch, a power supply, and a solenoid valve. When the handle starts the internal combustion engine, when the internal combustion engine reaches the normal starting speed, the electrical signal generated by the generator can make the relay and solenoid valve act, and the oil circuit of the internal combustion engine can be turned on. Otherwise, the internal combustion engine cannot reach the normal starting speed, and the oil circuit of the internal combustion engine is blocked. Can't get started. This device fundamentally eliminates the reverse rotation of the internal combustion engine, and prevents personal injury accidents and unsafe operation of the reverse rotation of the internal combustion engine.

Description

technical field [0001] The invention relates to a non-reversing device for starting a handle of an internal combustion engine, which relates to the technical field of internal combustion engines. Background technique [0002] At present, when the known internal combustion engine is started with a handle, due to lack of safety protection measures, the required starting speed is often not reached due to the insufficient power of the hand crank, and the energy accumulated by the flywheel cannot make the crankshaft reach the upper position from the position of the combustion advance angle. The dead center is pushed back by the combustion gas pressure, causing the internal combustion engine to reverse. Internal-combustion engine produces two kinds of harmful consequences after the reverse rotation, and one, crank handle reverses with crankshaft reverse rotation, causes the generation of personal injury accident. 2. The internal combustion engine is revers...

Problems solved by technology

[0002] At present, when the known internal combustion engine is started with a handle, due to the lack of safety protection measures, the required starting speed is often not reached due to insufficient power of the hand crank, and the energy accumulated by the flywheel cannot make the crankshaft reach the upper position from the position of the combustion advance angle. The dead center is pushed back by the combustion gas pressure, causing the internal combustion engine to reverse

Two kinds of harmful consequences are produced after the internal combustion engine reverses. First, the crank handle reverses with the crankshaft reversed, causing personal injury accidents

2. The internal combustion engine is reversed, the intake and exhaust strokes are reversed, the internal combustion engine makes abnormal noises, the oil on the air filter is discharged, the lubricating oil pump is reversed, and the oil cannot be sent to the friction surfaces, the parts are easy to wear, and the reverse time Long-term, "burning tiles" and "shaft holding" mechanical damage accidents
