what is camshaft (camshaft)? how does it work?

The motor that receives its motion from the crankshaft is the auxiliary shaft. When the crankshaft makes two turns in a four-stroke engine, the camshaft makes one round. In two-stroke engines, this is the ratio of the individual. The purpose of the camshaft is to adjust the opening and closing times of the valves. This shaft, which works in proportion to the engine revolution, is positioned on the engine with very fine adjustment for proper operation of the engine. The cam shaft is manufactured from high quality carbon steels usually by casting method. They are usually produced in high quality steel alloys by punching and pouring them in one piece. There are journals, cams and movement gears on the shaft.

The camshaft moves through the crankshaft by means of gears, chains or belts. The name of the belt to be used is the trigger belt which is among the vital parts of the engine. If the distance between the crankshaft and the camshaft is too close, the movement is transmitted by the gear contact. Gear transfer is actually the most efficient and trouble-free system, but this is not possible with engines with cylinders of the same type because the distance between them is too large to be transferred with the gear. In the V type motors shown above, gears can be used. Pitch motors use trigger belts or chains. The triger strap can break or peel, which can cause damage without motordated compensation. In the chain, breakage is less common and even if there is breakage, stopping the vehicle prevents damage to the motor. However, since the motion continues when the belt is strained, the valve timing changes, which can cause the crankshaft to break due to misaligned misregistration, and therefore, misfiring pistons.


The main task of the cam shaft is to open and close the valves as stated. In top-excited engines the camshaft cams and the bulbs are in direct contact. The camshaft moves the claw, the kickers open the valves. In side excursion engines, the cam of the cam shaft moves to push the valve. The valve pushes the movement of the cigarette and the kickers open the valve.

The auxiliary functions of the camshaft are to move the oil pump to and from the fuel dispenser and distributor if it is outside the pump. Wear often occurs at the tip of the cam and on the cheeks. At the end the overflow valve is opened to a lesser extent; the flap on the side causes the valves to operate audibly and to open and close early. The speed and duration of wear depends on the hardness of the cam surface, the valve clearance, the valve spring hardness and the duration of the change. The slightest change in the timing of the opening and closing of the valves results in poor burning, thus causing the engine to drop off.
