What Is The Role Of Timing Belt?

So that the timing of valves is always right, allowing them to intake air and exhaust stroke at the same time.

Essentially, it keeps the top half of the engine (cylinder head, valves) in sync with the bottom half (crankcase, pistons).

Timing belt is a ribbed belt made of rubber. Timing chain or timing belt serves the same purpose.

Most automotive manufacturers prefer timing chain in their cars due its longer durability.

Some people get confused in Timing and drive belt as well as Timing and Serpentine Belt. The first are the same but second are different.

There are some common warning signs of broken timing belt

1) Engine jolts or stops

Teeth on the engine belt grip gears and drive each accessory of the engine. When these teeth worn out, the timing belt starts to slip away from the gears and engine will stop running or form a thrust in the engine.

2) Misfire situation of the Engine

A worn out timing belt might have detrimental effect on engine’s fire rate. The reason is broken cog of the belt. In this way, the timing belt loses its grip and fall on the camshaft. This will cause one cylinder to open and close soon as compare to other. This situation is known as misfire situation and indicating a strong need of replacement of drive belt otherwise result can be disastrous.

3) Smoke from the Engine

The timing belt connects camshaft to the crankshaft, controls the opening and closing of the valves in the combustion engine. When timing belt is worn out, synchronization of the crankshaft and camshaft is jeopardized. This means exhaust of air and inhale of air through valves is on inappropriate times. The result will be lots of smoke from engine exhaust system.

This collision between piston and valves due to timing belt malfunctioning may result into major car repairs.

4) Low Oil Pressure or leakage of oil

As belt worn out, its pieces may break off into the oil pan of the vehicle. This will cause a catastrophic drop in the pressure of engine. This will cause engine failure. The only solution of ceased engine is to reconstruct the whole motor.

5) Ticking Sound from the Engine

The toothed belt is connected and surrounded by the various parts of the engine. Once the timing belt starts to worn out, it becomes loose, resulting in the generation of ticking sound. It will increase as the drive belt condition get worse n worse until it breaks down.

What Happens If It Breaks?

If your timing belt broke in interference engine of car drive belt connects crankshaft and camshaft and turns them together. This Results into smooth running of engine. So the essential role of timing belt is to keeps them smashing into each other. When timing belt breaks down, one has to tow ones car to the workshop. Because it will not start until the engine is re-timed.

When timing belt snaps, the valves stop moving. At the same time piston, unaware of the position of valve, comes up and smashes into valves. This result into bent valves, cylinder head or camshaft damaged.
