Car Engine Working Video
A car engine is a complex machine that converts the energy stored in gasoline into motion. The engine is made up of many different parts, all of which work together to create power. In this video, we’ll take a closer look at how a car engine works.
The Four Strokes of the Engine
The engine cycle is a series of four strokes that occur in each cylinder. The four strokes are:
- Intake stroke
- Compression stroke
- Power stroke
- Exhaust stroke
The intake stroke begins when the intake valve opens and the piston moves down the cylinder. This creates a vacuum that draws air and fuel into the cylinder. The intake valve then closes and the piston moves back up the cylinder, compressing the air and fuel mixture. This compression increases the temperature and pressure of the mixture, making it more combustible.
The power stroke begins when the spark plug ignites the air and fuel mixture. This causes the mixture to expand rapidly, driving the piston down the cylinder. The exhaust valve then opens and the piston moves back up the cylinder, pushing the exhaust gases out of the cylinder. The exhaust valve then closes and the cycle repeats.
The Parts of the Engine
The engine is made up of many different parts, including:
- Pistons
- Cylinder head
- Valves
- Camshaft
- Crankshaft
- Oil pump
- Water pump
- Fuel injector
- Spark plug
The pistons are located inside the cylinders and move up and down to create the power strokes. The cylinder head is located on top of the cylinders and contains the valves. The valves open and close to allow air, fuel, and exhaust gases to enter and exit the cylinders. The camshaft is located above the valves and controls their opening and closing. The crankshaft is located at the bottom of the engine and converts the up-and-down motion of the pistons into rotary motion. The oil pump circulates oil through the engine to lubricate the moving parts. The water pump circulates water through the engine to keep it cool. The fuel injector sprays fuel into the cylinders. The spark plug ignites the air and fuel mixture in the cylinders.
How the Engine Works
The engine works by converting the energy stored in gasoline into motion. The gasoline is mixed with air and injected into the cylinders. The spark plug ignites the air and fuel mixture, causing it to expand rapidly. This expansion drives the pistons down the cylinders, which in turn rotates the crankshaft. The crankshaft then converts the rotary motion into linear motion, which is used to drive the wheels.
Conclusion
The car engine is a complex machine, but it is also a very efficient one. Engines convert the energy stored in gasoline into motion, which is used to drive the wheels. This allows us to travel long distances in our cars.
