The engine component that opens and closes the valves is the camshaft. It is driven by the crankshaft and uses lobes to push against the valve lifters, which in turn actuate the valves. The timing of the camshaft ensures that the valves open and close at the correct intervals during the engine cycle, allowing for proper air and fuel intake and exhaust expulsion.
What else can I help you with?
The component that opens the valve in a four stroke engine?
On an overhead cam engine, the lobes on the cam push the rocker arms which push the valves open.
What opens the valves?
the valves are connected with the cams on the engine , the cams are rotated during the power stroke .
What is a cam ON A CAR?
The cam is in the engine and it is what opens and closes the intake and exaust valves
What is the valve size in your set of heads?
Depends on the heads. The size is different for the exhaust valve and the intake valve, and different engines have different size valves. The valves are mechanical devices in the engine heads that open and close. The intake valve opens to let the air/gas mixture into the combustion chamber,. Both valves close the combustion chamber during the compression stroke, and the exhaust valve opens to let the burnt gas out during the exhaust stroke.
Do heart valves require energy to open and close?
no... the force of the blood opens them and they naturally want to stay closed.
What the function of valves?
Valves prevent blood from going backward.Valves in general open to allow or close to prevent liquid flow. Heart valves opens to let blood into the heart then close to keep it there so that when the heart muscle contracts and squeezes the blood it is then forced out into the arteries of the body.
What part of the heart opens to allow blood in?
The heart valves open when blood is flowing through. They close to prevent backflow.
What is cams on a car?
Camshaft opens and closes the valves The CAMSHAFT is connected to the CRANKSHAFT with gears so that the valves (intake and exhaust valves) are opened and closed at the proper time for each cylinder, and fully sychronized for with the movement of all of the other parts of the engine.
What is the function of the valves?
Valves prevent blood from going backward.Valves in general open to allow or close to prevent liquid flow. Heart valves opens to let blood into the heart then close to keep it there so that when the heart muscle contracts and squeezes the blood it is then forced out into the arteries of the body.
What do Both valves on a four stroke reciprocating engine open the?
In a four-stroke reciprocating engine, both valves—the intake valve and the exhaust valve—open to facilitate the engine's four distinct strokes: intake, compression, power, and exhaust. The intake valve opens to allow the air-fuel mixture into the combustion chamber during the intake stroke, while the exhaust valve opens to release exhaust gases after combustion during the exhaust stroke. This coordinated opening and closing of the valves ensure efficient engine operation and optimal performance.
What component opens the flapper to allow air in for air fuel mixture on a fuel injected engine?
The idle air control (IAC) does this, not the "flapper".
Can side cam engine be installed in 4 stroke or 2 stroke engine?
sidecam engine cannot be installed in 2 stroke engine because in 2 stroke engine we have inlet & exhaust ports not valves... so when piston moves up and down it automatically opens the inlet and exhaust ports so it does not require any camshaft for opening of valves as it is required in 4 stroke engine
