How does the intake valve work?
The intake valve opens as the piston is going down. It lets in an air fuel mixture. The valve then shuts as the piston reaches the bottom.
What do piston do in a car?
A piston draws air into the cylinder through an intake port. The intake valve closes and the air/fuel mixture compresses as the piston moves back up. Once the mixture is fully compressed, it is ignited and explodes forcing the piston down (this is known as the power stroke). An exhaust valve opens and the burned gases are expelled out of the cylinder as the piston moves back up to complete its cycle. This is different from a heart valve. A heart valve would be similar to a bicycle tire pump though. As the piston draws air into the air chamber,the valve opens to allow the air to fill the chamber. the piston then, changes direction and pushes that valve closed and opens another valve to allow the air to be pushed out the air line. The difference is in the valves. a bicycle pump uses check valves. Check valves allow flow in one direction.
Why is your carburetor blowing air?
If the carb is blowing air OUT instead of sucking air in then you possibly have a bad intake valve. As the piston comes up then the air is forced out the intake valve and back thru the carb. Another possibility is that the timing chain or timing belt is broken and then the piston again is pushing the air out the intake valve. The definitive test would be to run a compression test.

How is the suction valve unloading piston on a standard type positive displacement air compressor operated?
air operated- spring return
How does a reciprocating air compressor work?
Both valves are closed when the piston is at top dead center ( TDC ) As the piston moves down, creates vacuum. The athmospheric pressure opens the intake valve allowing the cylinder to be filled with air. The intake valve will close at the point when the piston reaches the bottom dead center. ( BDC ) The piston start moving up compressing the air above. As the pressure increases, the outlet valve opens and the piston pushes the pressurized air to leave the cylinder. The pressurized air moves to the air tank. The oulet valve closes at ( TDC ) During compressor operation, the above process is repeated. Both valves are being operated by the pressure differences against springs. Reciprocating compressors do not have camshafts like the internal combustion engines. John
What do valves?
Valves regulate the flow of fluids in any system. In the human body, specifically, they keep blood from going to the improper places.If you are asking about cylinder head valves there are two types. Intake valves allow fuel and air into the cylinder and exhaust valves allow the smoke to leave the cylinder. The piston moves down sucking in the fuel/air mixture with the intake valve open (intake stroke). The Intake valve closes at the bottom of the piston stroke then the piston moves up compressing the air and fuel (compression stroke). The spark plug ignites the fuel and air when the cylinder is back at the top causing an explosion that forces the piston back down ( power stroke ). The exaust valve then opens and the piston moves back up forcing out the exhaust (exhaust stroke). The exhaust valve closes and the intake valve opens and the cycle starts over.
Where is the Air Intake Valve in Honda Civic 1998?
The only item that I can think of which could be classed as an air intake valve would be located in the cylinder head above the piston. It sits next to the exhaust valve. It opens in order for the fue / air charge to enter the cylinder.
What do the four strokes in an internal combustion engine do?
piston falls =vacuum = draw in fuel/air through intake valve piston rises compressing fuel / air mix, ignited at top,heat and pressure rise piston falls driven by pressure over piston area creating force, turning crank piston rises driving out exhaust gases through exhaust valve More commonly known as. Induction. Compression. Power Exhaust strokes. The humorous way to remember Suck Squeeze Bang Blow.
What is the mode of operation of a four stroke petrol engine?
Not sure what you are asking here... But here goes: Stroke 1: Intake stroke. The intake valve is open, and fuel air mixture is sucked into the cylinder as the piston moves down. Stroke 2: The intake valve is closed, and the fuel air mixture is compressed as the piston moves up. Stroke 3: The power stroke. The compressed fuel air mixture is ignited by the spark plug. The resulting explosion forces the piston down, providing power. Stroke 4: The exhaust valve is opened, and the spent fuel air mixture (now exhaust) is pushed out of the cylinder by the rising piston. Repeat indefinitely...
When do the intake valves of an engine open?
A intake valve open when the piston reaches the top of the cylinder and just after the exhaust valve closes. It allow fuel and air to enter the engine cylinder.
How does a four stroke engine work?
A four stroke engine has four cycles. Intake cycle, compression cycle, power cycle, and exhaust cycle. Each corresponds to one full stroke of the piston; therefore, the complete cycle requires two revolutions of the crankshaft to complete.Here is a brief explanation on how it works.Intake cycleThe intake valve opens, the piston moves downward and fuel and air is sucked into the cylinderCompression cycleThe Intake valve closes and the piston moves upward, compressing the fuel and air mixture.Power cycleA spark plug ignites the fuel/air mixture and the piston is forced downwards.Exhaust cycleThe piston moves upward and the exhaust valve opens, letting the fumes out of the cylinder.
