The camshaft, or camshaft, is an important element of the gas distribution mechanism of an internal combustion engine. Many drivers are interested in where the camshaft is located in a car, especially when they encounter engine repair or diagnostics. Let's figure out where it is located, what it looks like, and what it is for.
Where is the camshaft located in a car
The camshaft is located in the cylinder head (cylinder head) - this is the upper part of the engine. Depending on the engine design, the camshaft can be located both at the top (in overhead valve engines like OHC or DOHC) and in the lower part of the block (in old pushrod engines OHV). In modern cars with overhead valves, the camshaft is located directly above the valves, ensuring their opening and closing with high precision. To be more precise, it is installed in the cylinder head parallel to the crankshaft and rotates synchronously with it thanks to a drive belt or chain.
What is the camshaft for
The camshaft is responsible for the timely opening and closing of the intake and exhaust valves of the engine. Its design includes cams that press on the valves, regulating the supply of the fuel mixture and the exit of exhaust gases. Without a working camshaft, the engine simply cannot operate efficiently.
Where is the camshaft located: one or two?
Depending on the engine design, there can be one camshaft (SOHC - Single Overhead Camshaft) or two (DOHC - Dual Overhead Camshaft). In the case of two camshafts, one is responsible for intake, the second for exhaust. If you want to understand where the camshaft is located in a car, open the hood and find the cylinder head cover. Under it is the shaft. In some cars, the cover even says: "DOHC" or "16V", which means the presence of two camshafts.
How to determine a camshaft malfunction
If the camshaft is damaged or worn, this can be noticed by a number of symptoms:
- unstable engine operation;
- loss of power;
- extraneous knocks in the engine;
- difficulty starting.
In some cases, the "Check Engine" light comes on on the dashboard. Although this can signal other malfunctions, the camshaft is also worth checking.So, now you know where the camshaft is located in a car: in the cylinder head, above the valves. It plays a key role in engine operation, ensuring precise synchronization of the valves. If the engine starts to run unstable or an error appears, perhaps the problem is in this element. Diagnose problems in a timely manner and trust repairs to professionals.
