Combustion engine hand lever starting counter-rotation proof apparatus

Abstract

The internal combustion engine hand shank starting-up reversal proof apparatus in accordance with the present invention relates to the internal combustion engine technology field. The invention provides an internal combustion engine hand shank starting-up safeguard device consisting of an electric generator, a main circuit manual switch, an electric relay, a control circuit manual switch, an electrical source and an electromagnetic valve. When the internal combustion engine is started up by using a hand shank, the electrical signal generated by the electric generator causes the conduction of the electric relay, the electromagnetic valve actuating and the oil channel of the internal combustion engine only when the internal combustion engine achieves its normal starting rotary speed; or else, if the internal combustion engine can't achieve its normal starting rotary speed, the oil channel of the internal combustion engine is obstructed, and the internal combustion engine can not be started. Radically, said apparatus eliminates reversals of an internal combustion engine, and then avoids personal disservice accidents and reverse operative unsafe operation of an 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 reversed, the intake and exhau...

AI Technical Summary

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
