Principle and introduction of timing gear of engine
From the above process, we can see that the engine can only work, and the intake and exhaust valves and oil supply are guaranteed according to the exact opening and closing of the piston position, and the oil supply. This relationship is guaranteed by the timing gear. The assembly relationship between the three gears is to ensure that the normal operation of the anti - motivation. Principle is the ratio of gear to gear.
Four travel motivation anti working principle, refers to the reciprocating piston in the cylinder two, with suction, pressure, explosion, row four basic requirements for the realization of the energy conversion, simply said that when the piston down the inhale, the intake valve must be opened, when the piston compressed gas inlet and exhaust valve must close, timely supply when the compression end (ignition), high-pressure gas explosion pushes the piston down, the piston upward again when the exhaust valve must be opened, exhaust emissions after combustion
There are three key gear, engine timing gear box is connected with the crankshaft gear solid crankshaft; cam shaft gear and cam drive valve; and the driving shaft is connected to the high-pressure pump high pressure pump gear; the three gears are timing gear.
