How long does the car engine belt change? What is the effect of the engine belt
Timing, is through the engine timing, just do: let every cylinder piston up just to top dead center, the valve is closed, the spark plug ignition. Belongs to consumable parts, timing belt and timing belt once fracture, camshaft timing, of course not, according to at this time is likely to lead to valve and piston impact caused serious damage, so the timing belt must be replaced for mileage or time according to the original factory. Automobile engine working process, the air intake, compression, constantly taking place within the cylinder explosion, four process exhaust, and the timing of each step should be to match the piston motion and position, make the air intake and exhaust and piston lift mutual coordinate, timing belt inside the engine play a "bridge" role, in leads to the crankshaft strength is passed to the corresponding parts. There are a number of premium cars to keep the system stable and use metal chains instead of belts. Due to the damage of the internal valve of the engine due to the failure of the belt fracture of the vehicle, the general manufacturer has a replacement cycle for the timing belt.
Timing belt, Timing belt) is an important part of engine distribution system, through the connection with the crankshaft and comply with a certain ratio to guarantee the accuracy of the inlet and exhaust time. Using a belt rather than a gear is driven by low noise, accurate transmission, small variation and easy to compensate. Obviously, the belt must be shorter than a metal gear, so be sure to change your belt regularly. The role of the timing belt is when the engine is running, the piston stroke (up and down movement) of valve open and close (time) order of ignition (time), in the "timing" connection, the moment to keep "synchronous" operation
Belt belong to rubber parts, and we all know, the rubber will be aging, auto timing belt usually lasts for two years, because the engine at high temperature, in the operation of car stalled after cooling, oily impurity and matching and installation of timing belt up incorrect practices timing belt can lead to shorten the service life. So this again raise the question of another mileage, a new timing belt run between 8-100000 - km (except some cars such as the nanjing iveco, chery automobile's banner, because of engine problems generally 2-30000 - km must be replaced timing belt), after you change the timing belt, because the depreciation of the car, use, installation, and other issues, so the service life of the timing belt will reduce accordingly, so a lot of repair, 4 s shop will give travel 60000 km, the best timing belt replacement. So, in order to ensure that the service life of your engine, for your love car to more reliable and timely maintenance, advice to you is: average family car, timing belt for a year and a half to two years must be replaced, or change the timing belt should pay attention to travel 60000 km!
