What is the function of an engine front end?
The primary purpose of an engine front end is to drive the camshaft or camshafts. In a four-stroke cycle piston engine the cam must turn at one half crankshaft speed. This will make the valves open up the right times during the four-stroke cycle. The front and often drives the engine oil pump.
Is an engine front cover the same as a timing belt cover?
It is also called the timing cover. A seal press fitted into engine front cover that prevents oil leakage between a crankshaft and engine front cover. … It blocks dirt and debris while preventing oil leakage.
What can happen if a harmonic vibration is not controlled in an automotive engine?
Although the harmonic balancer may seem simple enough, if it fails, it can cause major problems. Without the balancer dampening unwanted crankshaft vibrations, engine failures, such as worn rod bearings and a broken crankshaft, may result. A faulty balancer can damage the belt and engine-driven accessories as well.
What transfers power from the crankshaft sprocket to the camshaft sprocket?
There are three basic types of camshaft drives: gear drive, chain drive, and belt drive. Gear drive: Timing gears are two helical gears on the front of engine that operate the engine camshaft. Timing chain and two sprockets: the timing chain transfers power from the crank sprockets to the cam sprockets.

What keeps the crankshaft in place?
In a piston engine, the main bearings are the bearings which hold the crankshaft in place and allow it to rotate within the engine block. Main bearings are usually plain bearings or journal bearings, held in place by the engine block and bearing caps.
What’s the difference between camshaft and crankshaft position sensor?
The crankshaft position sensor monitors as a multifunctional sensor used to set ignition timing, detect engine RPM and relative engine speed. … The camshaft position sensor is used to determine which cylinder is firing to synchronize the fuel injector and coil firing sequence.
