How fuel works in cars engine?
All gasoline engines are four-stroke designs. An engine has an intake stroke where the intake valve is open and the piston is moving downward, creating a vacuum that sucks the fuel into the cylinder. The next stroke is the compression stroke. The intake valve closes, and the piston begins to move upward and compresses the fuel in preparation for ignition. The third stroke is the power stroke. The piston is approaches the top of the cylinder in the compression stroke. Just before it gets to top dead center, the spark plug fires and ignites the fuel. The fuel rapidly expands and pushes the piston down with great force. The last stroke is the exhaust stroke. In this stroke, the piston completes the power stroke and begins to rise again. At this point the exhaust valve opens, and the piston forces the exhaust out of the cylinder in preparation for the intake stroke.
How many intake events are there in one revolution of a four cylinder engine?
There is only one intake stroke in a four-stroke engine. The other three strokes are compression, power, and exhaust. The intake stroke is a down stroke of the piston in which fuel is drawn into the cylinder while the fuel intake valve is open. The next stroke is the compression stroke in which the valves are closed and the fuel is compressed for combustion. The following stroke is the power stroke - a downward stroke of the piston after fuel combustion that drives the crankshaft. The final stroke is the exhaust stroke, an upward stroke of the piston as the exhaust valve opens to relieve the exhaust fuel fumes.
What are the steps to how a 4-stroke engine works?
Suction stroke - Air and vaporized fuel are drawn in.Compression stroke - fuel vapor and air are compressed and ignited.Power stroke - fuel combusts and the piston is pushed downwards.Exhaust stroke - Exhaust is driven out.
Diffenerence between 2 stroke and 4 stroke?
The difference is in the amount of stokes the piston makes in one cycle. A four stroke will explode on one stroke turning the engine over. Then on the up stroke it pushes the exhaust out. The next down stroke fills the cylinder with fuel. On the final stroke the piston compresses the fuel and the cycle repeats. This results in four strokes of the piston. A two stroke has two strokes of the piston before it repeats the cycle. The first stroke is the explosion. The piston is pushed down. on the down stroke the piston reveals a port that exhausts, and then another port is revealed that fills the cylinder with fuel. the up stroke compresses the fuel and then the cycle repeats. The logical difference is the 2 stroke will accelerate faster
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.
How does a two stroke engine sucks up fuel?
The suction created by the descending piston sucks the fuel/air mix through the carburettor.
What is cc of 4-stroke engine?
the term 'cc' means cubic centimetre which gives the stroke volume of an engine. basically it is the volume of cylinder in which fuel burns to give movement to piston.
Why does your car knock when you push the gas?
That is a lower grade of fuel then your engine was designed to burn. That is called detonation of fuel which means the fuel is burn before the piston is in the right position to be pushed down in the power stroke, Adjusting the timing is required if the fuel grade is correct. The sound itself is the piston about to go into power stroke is pushing slightly against the rest of the engine.
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...
How does an internal combustion engine 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. If anyone was wondering, a 14 year old wrote this explanation.
Why in two stroke engine at the place of valve there is valve?
In a typical two stroke (petrol) engine, the valves are replaced by ports in the cylinder wall, and closed / unclosed by the motion of the piston. Piston rising, vacuum under draws (fuel) mix into the crankcase through the carburettor. Piston falling, inlet port closes, pressure forces mix up through transfer ports into combustion chamber. Rises and fires at TDC, then falls to uncover exhaust port.
Why fuel consumption is less in 4 stroke engine then in 2 stroke engine?
