How to Distinguish Between Intake and Exhaust Camshaft Letters?
1 Answers
Distinguishing between intake and exhaust camshaft letters: Observe the differences in screw positions and belt locations on the camshafts. The camshaft is installed at the top of the cylinder head and functions to drive the intake and exhaust valves to open and close. Both intake and exhaust camshafts are equipped with a drive wheel, which is directly rotated by a chain or belt. Some engines use chain drive to rotate the camshaft, aiming to reduce the valve angle. The principle is: one camshaft is driven by chain transmission, and then the gear installed on this camshaft drives the other camshaft via chain.
