Air leakage between throttle and intake valve

The function is completely different. Throttle, also known as throttle, controls air intake and is controlled by accelerator pedal, and is generally installed on the intake manifold. The intake valve is a piston controlled by the camshaft of the engine. When the intake valve is opened, air can flow into the cylinder. Exhaust valve is the place where exhaust gas is discharged after engine combustion.
