Why Do Engines Need "sharper" Camshafts At Low Revs And "rounder" Camshafts At High Revs?
2022-02-14
.jpg)
At low revs, the reciprocating motion of the engine pistons is slower, and the suction force to draw the mixture into the cylinders is reduced. At this time, the intake valve needs to be opened for as long as possible, and when the piston runs to the bottom dead center and enters the compression stroke, the intake valve is closed instantly to prevent the mixed gas from flowing out. Whereas a camshaft with a "sharper" cross-section closes the intake valve more quickly, a "rounder" camshaft takes longer to close. So, at low rpm the engine needs a "sharper" camshaft.
At high revs, the piston of the engine reciprocates faster, and the suction force to draw the mixture into the cylinder is stronger. Even when the piston runs to the bottom dead center and is about to enter the compression stroke, the mixed gas will swarm into the cylinder at this time and cannot be interrupted. Of course this is what we want, because if more of the mixture can be drawn into the cylinder, then the engine can get more power. At this time, we need to keep the intake valve open when the piston rises, and do not close it for the time being. The "rounder" camshaft is now on the scene!
The shape of the engine cam section is closely related to the engine speed. To put it simply, at low revs we need a "sharper" camshaft; at high revs we need a "rounder" camshaft.Copyright © Changsha Haochang Machinery Equipment Co., Ltd Site Index Product Index Technical Support :coverweb
