8/18/2023 0 Comments Timing belt failure symptoms![]() Now that you know how important the functioning of the inlet and exhaust valve is, let’s take a look at how the timing belt manages to keep the function in perfect harmony. For that, the exhaust valve has to open at the precise moment or the pressure level inside the combustion engine might increase above the design limit. At this point, the exhaust valve opens and the residue gas is pushed out. This chemical reaction leaves a combination of carbon and other gases that should be removed from the engine. Once the air-fuel mixture is compressed, the spark plug generates a spark which results in a controlled explosion of the mixture, creating excessive pressure and pushing the piston downwards. At this moment, both of the valves must be closed to avoid loss of pressure. After that, the piston is pushed upwards to compress the mixture and decrease its ignition point as low as the temperature of a spark. For that, the inlet valve must open at the exact moment when the piston has reached its lowest position. When the engine is activated, it pulls the piston downwards creating a vacuum in the combustion chamber which is then filled with a mixture of air and fuel. As you may already know, the crankshaft and valves are the components that must always be synchronized with precise delay in rotation to achieve perfect inlet and exhaust in the engine. As for the construction, the belt is quite simple as it is made up of rubber with an internal teeth-like structure that locks onto the teeth of a gear. The belt controls both, the piston as well as the valve to ensure proper working of the engine at all times. The timing belt, as the name suggests, is a simple belt drive that transfers the motion of the crankshaft to the valves to adjust the timing of their rotation. When Should You Replace The Timing Belt?.How Much Does Replacing a Timing Belt Costs?.If you want to know more about the timing belt, stick until the end of our guide where we will talk about the symptoms of a bad timing belt and how you can replace it yourself.īefore we dive deep into the topic, let’s get familiar with the timing belt itself and see how it works inside an engine. Today, we are going to understand the timing belt and how it functions inside a standard internal combustion engine. Even a slight delay in the opening or closing of either of these valves can result in failure of the engine, if not worse. One of the most important components out of these is the timing belt which connects the crankshaft and camshafts in your engine.Īs you can imagine, the timing of the inlet and exhaust valve has to be very accurate and precise for proper functioning of the engine. Even though your car operates on a number of large components, there are a number of subsidiary parts in your cars such as chain drive, operating fluid, and timing belt which maintains a uniform transfer of power through these components.
