X6 105B Is the intake valve in front or behind?

X6 105B Intake valve is at the back. When you find the engine air filter, you will basically find the throttle. The position of each car will be different, and the throttle of some models will be covered by the hood. Opening the lid will be more intuitive. When the hood is open, the position of the throttle can be clearly seen. To remove the throttle valve, you must first remove the hose connecting the air cleaner and the throttle valve.

Definition of valve

Valve refers to the intake valve and exhaust valve of the cylinder. The intake valve is directly connected with the intake manifold, which is the inlet for the engine to inhale the mixed gas, while the exhaust valve is connected with the exhaust manifold, which is the outlet for the engine to discharge the combustion exhaust gas.

The efficiency of intake and exhaust is an important factor to determine the engine performance. When the engine is running normally, the reciprocating speed of the piston is very fast. At 3000 revolutions per minute, the engine takes only 0.04 seconds to complete each intake or exhaust stroke. In order to inhale or exhaust more gas in such a short time, it is necessary to increase the effective area of intake and exhaust.
