Which stroke is occurring when the engine draws in fuel and air?
The intake stroke, number one in a 4 cycle engine.
How does internal combustion engin work?
A 4 stroke gasoline internal combustion engine operates on a 4 stroke cycle, hence the name, "4 stroke engine". The first stroke is the intake stroke, the piston moves down the cylinder, which creates a vaccume, which draws in fuel and air from the induction system. The second stroke is the compression stroke. The piston starts at the bottom of the cylinder and begins to move up, compressing the air and fuel mixture. Just before the piston is at the top of the cylinder (top dead center), the spark plug fires, igniting the compressed air and fuel mixture. The resulting explosion causes the 3rd stroke, the power stroke. The force of the explosion pushes the piston back down the cylinder, turning the crankshaft. The 4th and final stroke is the exhaust stroke. After the power stroke, there is exhaust gas left in the cylinder. The piston moves back up as the exhaust valve opens, pushing the gases up the cylinder and out the exhaust. This cycle continues thousands of time per minute as the engine is running.

How does a 4 stroke engine work?
As the name states there are 4 strokes in a 4 stroke engine. Intake, when the piston draws in air/Fuel mixture. Compression, when the intake valve closes and the piston moves to the top off the stroke. Power stroke, when the compressed mixture is ignited, forcing the piston down. Last the exhaust stroke when the piston starts moving up and expells the burnt gases.
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.
Fuel is combusted in the stroke of a four-stroke engine.?
In the power stroke:Intake stroke --- draws the fuel mixture into the cylinderCompression stroke --- pressurizes the fuel mixturePower stroke --- ignites the fuel and causes the product gases to push against the pistonsExhaust stroke --- expels waste gases from the cylinder* PIE C is a good way to remember it. Or C PIE. *

What is a 318 ci motor?
The ci stands for Cubic Inch. This refers to the displacement of the engine. So, it is most likely saying that the motor is a 318 cubic inch motor. What that means is, the cylinders of the motor each have an amount of fuel air mixture that they can suck in as each cylinder draws in the fuel air mixture on the intake stroke. If the engine is a V8, meaning it has 8 cylinders configured in the shape of a V, you could find the displacement of each cylinder by diving 318 by 8.
Do diesels have vacuum?
Yes, any piston engine draws air in when the piston move downward on the intake stroke, and as a result does create a lower pressure with respect to the atmospheric pressure around the engine.
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.
What part does an intake manifold play in an engine?
the intake manifold is what draws in the air,separates and funnels it to the individual cylinders.
