The camshaft opens the valve via its Lobes, against the valve spring, to open. The valve springs closes the valve back.

What is the difference between a camshaft and a crankshaft?
The connecting rods and pistons are connected to the crankshaft. Ignition of the air/fuel mixture in the combustion chamber pushes the pistons down which rotates the crankshaft which generates the engines torque/power. The camshaft controls the opening and closing of the valves which allows the air/fuel mixture to flow in and out of the engine. The camshaft is driven by the crankshaft and is kept in proper sequence by a timing belt/chain or gears.
What controls the opening of engines valves?
The camshaft.
Why does a cam shaft run at half the speed of the crankshaft?
The four strokes of a four-stroke engine are intake, compression, power and exhaust. The crankshaft controls the upward and downward motion of the pistons. The camshaft controls the opening and closing of the intake and exhaust valves. Intake stroke- the intake valve is open and the exhaust valve is closed. The piston moves downward, decreasing the pressure in the cylinder, which draws the fuel-air mixture in through the intake valve. Compression stroke- both the intake valve and the exhaust valve are closed. The piston moves upward, compressing the fuel-air mixture. When the piston nears TDC (top dead center), the fuel-air mixture is ignited by the spark plug. Power stroke- both the intake valve and the exhaust valve are closed. The explosion caused by the ignition of the fuel-air mixture (combustion) forces the piston downward. Exhaust stroke- the intake valve is closed and the exhaust valve is open. The piston moves upward, forcing the gases produced by combustion out of the cylinder through the exhaust valve. So, for each firing of a given cylinder, the intake valve opens once and the exhaust valve opens once. But, for each firing of a given cylinder, the piston must travel downward and then upward twice (in each direction.). Therefore, the crankshaft must rotate twice per given cylinder firing, while the camshaft rotates only once per given cylinder firing.
What does a crankshaft sensor do on a Chevy 5.7?
Controls the ignition timing.
What controls the opening and closing of the valves in an engine?
push rods connected to the camshaft
Is there an adapter for electric dryer to hookup to gas line?
No. An electric dryer has no burner or combustion controls.
What are the function of a crankshaft?
the function of the crankshaft in relation to an engine is to turn up and down motion to round and round motion.
What has the author Paul G Burman written?
Paul G. Burman has written: 'Fuel injection and controls for internal combustion engines' -- subject(s): Internal combustion engines
Has a motor got a cam in it?
yes but only if it is a 4 stroke the cam or camshaft controls the fuel intake and exhaust valves
Which of the following is NOT a control for the experiment described in the question below?
Which of the following is not true about controls in an experiment
Which of the following components controls the opening and closing of the valves in a engine?
Rocker arms, in conjunction with the camshafts, do so. The camshaft has an egg pattern on it, and this pushes the rocker arms up and down. The rocker arms are connected to the valves, and this puts the fuel/air mixture into the engine, then takes it out again
Nitrogen is used for?
- Controls combustion-Dilutes activity of oxygen in the air -Essential for growth of plants and animals- constituent for proteins
