This is how a gasoline engine works
Gasoline engines are also called petrol engines in many parts of the world. British people use the word “petrol” to describe a gasoline engine.
Gasoline engines are the most common type of engine found in vehicles that people drive every day. They use the internal combustion process, which mixes gasoline and air in the cylinder chamber and ignites them to produce heat energy. This is the type of energy that allows a vehicle to accelerate according to the driver’s demand. Here we look at how an engine works and its history.
The four-stroke cycle of a gasoline engine
Stroke #1
The first cycle of the engine is to draw in outside air. The engine needs this air as part of the mixture.
First, the intake valve opens and air enters. The piston at the top of the cylinder moves down. This creates a force that draws air into the cylinder.
Stroke #2
The second measure is mixture compression. When air enters the cylinder and mixes with fuel, the force of the moving piston compresses the mixture.
Meanwhile, the exhaust and intake valves remain closed. It’s important that they remain sealed, otherwise valuable gases and liquids could leak out and ruin the entire combustion process.
Stroke #3
The third cycle is the actual combustion, also known as the duty cycle. This is when the mixture is actually ignited by the spark produced by the spark plug.
If ignition is successful, the explosion pushes the piston down, causing the crankshaft to rotate.
Stroke #4
The fourth stroke is concerned with exhaust. As fuel burns in the combustion chamber, it creates a mist of particles known as exhaust gases. The piston pushes these emissions out of the combustion chamber through the exhaust valve opening. History of the Gasoline Engine
Nikolaus Otto invented the gasoline engine and this four-stroke process. He was a German engineer who patented the invention and called it the Otto cycle. This allows for better and more accurate calculations of the fuel flow rate into the combustion chamber.
