Why does inlet valve opens before the beginning of suction stroke?
for completely entering of fresh charge the inlet valve opens before suction stroke
Why we open the inlet valve on the exhaust stroke and the exhaust valve on power stroke?
While there may be some overlap of valve opening timing, generally speaking, the exhaust valve opens after the power stroke, and the intake valve opens after the exhaust stroke. Recap... We start the combustion cycle of a standard 4-stroke engine with the intake stroke, the intake valve is open and the vacuum created by the downward movement of the piston draws in the air/fuel mixture from the intake manifold. The intake valve closes as the piston rounds bottom dead center and the compression stroke begins on the upward movement of the piston. At or near the top of the compression stroke, the spark plug fires (both valves are closed at this point) and begins the downward power stroke. As the piston rounds bottom dead center again, the exhaust valve opens to allow the piston to push out the exhaust gasses during the upward exhaust stroke. As the piston gets to the top, the exhaust valve closes and the intake valve opens to start the process over again.
Describe the position of the intake valve and the exhaust valve during each stroke of a four stroke engine?
In a four-stroke engine, the intake valve opens in the intake stroke, allowing air-fuel mixture to enter, while the exhaust valve remains closed. During the compression stroke, both valves stay closed to build pressure. In the power stroke, the fuel ignites, pushing the piston down, with both valves still closed to retain pressure. Finally, in the exhaust stroke, the exhaust valve opens, allowing gases to escape, while the intake valve stays shut. This cycle repeats continuously, ensuring efficient engine operation.
What is the function of an exhaust valve?
It relieves the cylinder of exhaust on the 4th stroke of a 4 stroke engine.
Name the two engine valves on a four-stroke engine?
Intake valve and exhaust valve.
What is valve lapping?
Is the time when intake and exhaust valve remain oper during the exhaust stroke.
How can you differentiate 2 stroke and 4 stroke vehicle by appearance only?
The most obvious difference is that a two stroke has no valves and valve gear.
What is valve over lap?
Is the time when intake and exhaust valve remain oper during the exhaust stroke.
What is the purpose of the butterfly valve inside the induction airbox of a piston engine?
The purpose of butter fly valve is to maintain one way opening during induction stroke and exhaust stroke.
