1 Answers
The timing belt of the 2012 New Focus is generally recommended to be replaced at around 120,000 to 130,000 kilometers. Timing Belt: The timing belt is a crucial component of the engine's valve system. It connects to the crankshaft and operates at a specific gear ratio to ensure the precise timing of intake and exhaust. The use of a belt instead of gears for transmission is due to its quieter operation, minimal variation, and ease of compensation. Function of the Timing Belt: The timing belt serves as a link between the upper and lower parts of the engine. The upper part connects to the timing pulley on the engine cylinder head, while the lower part connects to the crankshaft timing pulley. The timing pulley is connected to the camshaft, which has cams that interact with small rocker arms. The rocker arms generate pressure through the power transmitted by the timing belt, lifting the valves. Lifting the intake valve allows atomized gasoline to enter the cylinder, while lifting the exhaust valve allows exhaust gases to exit the cylinder. When the recessed part of the camshaft simultaneously contacts the rocker arms, both the intake and exhaust valves close, creating compression. The distributor then sparks, initiating combustion and generating power.
