What is a camshaft?
A camshaft is a part of a car engine that is responsible for controlling the opening and closing times of the air and exhaust valves. This part has protrusions called cams that open and close the valves at the right time by rotating the camshaft. The movement of the camshaft is usually taken from the crankshaft by a timing belt or timing chain. Its precise coordination with other engine components is essential for optimal performance.
Camshaft Position Sensor
The camshaft position sensor is an electronic component in a car engine that detects the exact position of the camshaft. This information is sent to the engine control unit (ECU) to adjust the appropriate timing of fuel injection and ignition. The correct functioning of this sensor is vital for the smooth and optimal operation of the engine. Its failure can cause poor starting, reduced engine power, or sudden shutdown.

The use of camshafts in a car engine includes the following:
1. Opening and closing the valves at the exact time for air to enter and smoke to exit.
2. Adjusting the valve timing according to engine speed and operating conditions.
3. Controlling the combustion cycle in coordination with the crankshaft and timing system.
4. In some engines, the activation of the fuel pump or delco is also done with the help of the camshaft.
Camshaft Features:
1. Has protrusions called cams to open and close the valves.
2. Made of durable steel or cast iron to resist wear and heat.
3. Has a precise design to coordinate with the crankshaft via a timing belt or chain.
4. May be located in the cylinder head (in DOHC or SOHC engines) or inside the cylinder block.

How the camshaft works:
The camshaft is driven by the crankshaft (usually at half the speed of the crankshaft).
The cams open the valve by pressing on the valve stem, rocker arm, or directly on the valve.
After the cam rotates, the valve spring causes the valve to close.
This process is precisely coordinated with the ignition timing and engine performance.
The camshaft in mining machinery, like in light vehicles, is responsible for controlling the timing of the opening and closing of the air and exhaust valves, but it comes with more specific features and conditions:

Features of camshafts in mining machinery:
1. High resistance to pressure and heat due to working in harsh conditions and heavy loads.
2. Longer life using resistant alloys and special heat treatment.
3. Custom-designed and reinforced for heavy-duty diesel engines.
4. Accurate and error-free operation to maintain engine power and efficiency in dusty and high-temperature environments.
