Home | What is a timing chain and what does it do in your car’s engine An engine’s timing chain keeps the movement of the components in the top half of an engine in synchronisation with those in the bottom half. In the top part of the engine, the timing chain is attached to the end of the camshaft, which has numerous lobes along its length.
What happens when you adjust the timing on a diesel engine?
When you adjust the timing, you can alter when the engine injects the fuel, therefore changing when combustion occurs. An injection pump is often driven indirectly from the crankshaft by chains, gears or a timing belt that also moves the camshaft.
What happens if your timing chain breaks while driving?
A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves. The valves themselves will bend and potentially ruin the engine.
