What are the functions and functions of the car timing belt
The main function of the automotive timing belt is to drive the valve mechanism of the engine, to ensure that the opening and closing time of the intake and exhaust valves is accurate, so as to ensure the normal operation of the engine . The timing belt is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the inlet and exhaust time, so that the stroke of the piston, the opening and closing of the valve and the ignition time keep synchronized .
How the timing belt works
timing belt (timing belt), also known as the timing belt, it runs according to the rule of time, connecting the crankshaft belt wheel and camshaft belt wheel. The power provided by the crankshaft belt wheel drives the valve controlled by the camshaft to open and close regularly to complete the process of intake - compression - explosion - exhaust of each cylinder of the engine, so that the engine generates power .
Other features of the timing belt
ensure power output and acceleration : timing belt is rubber products, low cost, small transmission resistance, to ensure the normal power output and acceleration performance of the engine, at the same time, the noise is also small .
reduce transmission energy : compared with the timing chain, timing belt has the advantages of less transmission energy consumption, fuel saving, not easy to stretch, silent .
consumable : because the timing belt is rubber products, relatively short service life, high failure rate, long-term use is easy to aging and fracture, so it is necessary to replace regularly.
Replacement interval and maintenance suggestions
replacement cycle : It is generally recommended to replace the vehicle according to the mileage recommended in the maintenance manual of the purchased model. Usually, the timing belt is recommended to be replaced once for 80,000 kilometers. Considering the design defects of some models or the aging of parts and other factors, it is recommended to inspect 50,000 to 60,000 kilometers .
replacement suggestions : when replacing the timing belt, it is best to replace the timing tightening wheel/transmission wheel together to prevent engine failure due to sudden death of the old wheel train/structural design/installation problems .
