The use of a Timing Chain or Timing Belt largely depends on the country and the regulations adopted by each automaker in different regions.Īlfa Romeo Spider Type 916 and 939 Audi Audi models with timing chain List of Audi models that are equipped with Timing Chain Model:īMW BMW models with timing chain List of BMW models that are equipped with Timing Chain Model: Why Use Timing Chain Brands of cars with timing chain. Manufacturers such as BMW, Opel, Volkswagen, Ford, Peugot, Mercedes and many others equip many of their models with timing chains, and the main reason for doing so is that the chains are much more reliable, the risk of wear or breakage is minimal and they can withstand much higher load than timing belts. Why? The truth is that major car manufacturers prefer to rely on timing chains, especially on turbocharged cars or cars in the higher price range. Since the timing chain consists of metal links, it must be constantly lubricated engine oil.Ī large number of manufacturers and owners continue to prefer timing chains.The price of a timing chain is much higher than that of a timing belt.A running timing chain makes much more noise than a timing belt.In addition, the extra weight affects the performance of the engine. This results in increased fuel consumption (higher environmental pollution). A timing chain weighs more than a toothed belt.The rotation of the chain is less smooth compared to a toothed belt, which dampens vibrations. Unlike the rubber that makes up the timing belt, the metal of the timing chain is as resistant to temperature extremes as possible.The timing chain does not require maintenance, except for a check at a mileage of 200 kilometers.The timing chain will last as long as your engine. Due to its reliability and wear resistance, the timing chain does not require replacement. Timing chain durability is its biggest advantage.High resistance to engine speedįeatures of the timing chain and belt ✔️ Timing Chain Advantages The service life is equal to the service life of the engine. Simply put, the function that both the timing chain and the belt in the car perform is absolutely identical and includes the synchronization of the pistons and cylinders in the engine so that it can operate smoothly and efficiently. For the engine to work properly, the movement of the pistons and cylinders must work synchronously, and it is during this time that the timing chains or timing belts are responsible. The relationship between the rotation of the camshaft and the crankshaft is called “mechanical synchronization”. During the process, the camshaft rotates once, and the crankshaft rotates twice. Timing chain or belt - similarities and differencesĪutomotive internal combustion engines use four clock cycles to complete the combustion process (shock, compression, fuel and exhaust). Timing belt - Like the timing chain, it is a component of an automobile engine that acts as a transmission to drive the camshaft at half speed and in sync with the crankshaft. The timing chain may be single, double or triple depending on what model of car you are talking about. The design of the timing chain allows it to be connected to various gears and wheels. The timing chain transmits the movement crankshaft distributive rampart and consists of many metal links like a bicycle chain. Valve train chain is to do the engine of the car, which is in engine car and synchronizes its various parts so that they can work in sync. What is a timing chain and what is a timing belt?
