Valve timing is a mechanism using valves to control the flow of working gases (air, fuel, exhaust gases) through a piston combustion engine. This is the most common type of mechanical distribution, used mainly in four-stroke internal combustion engines.

The opening of the valves is controlled by the respective cam of the camshaft, which is driven by the crankshaft. In four-stroke engines, the camshaft rotates 2x slower than the crankshaft, because one working cycle of the engine takes two revolutions of the crankshaft.

Timing belts play a key role in internal combustion engines. They synchronize the crankshaft and camshaft rotation to ensure proper valve timing, allowing for efficient engine performance.

In this article, we will shed light on the function of timing belts, what they are made of, and when to change them.

The torsional vibration damper is used to dampen crankshaft vibrations that occur during the combustion process.

These dampers are located at the end of the crankshaft and the pulley.

Connecting rod is a mechanical part that connects the piston to the crankshaft and ensures the transmission of forces between the pistons and the crankshaft. One part of the connecting rod is attached to the piston, while the other is attached to the crankshaft.

This article will shed light on the connecting rod's function and possible faults. In addition, we will briefly discuss its construction and mention the most common issues with connecting rods and their solutions.

The crankshaft is the mechanical part of a reciprocating internal combustion engine that converts the rectilinear reciprocating motion of the pistons into rotary motion. It is the basic part of the piston combustion engine.

In this article, we will shed light on the function of the crankshaft, what it is made of, and what it must bear.
