An internal combustion #engine is a #thermal engine that converts the chemical #energy inherent in fuel ( gasoline or #diesel ) into useful kinetic energy (torque)
internal combustion engine types: piston , turbine , rocket … etc
The #piston internal combustion engine works through oxidation of fuel and the production of heat and pressure that moves the piston
The engine cycle is divided into strokes and the engine is classified accordingly into a two-stroke and four-stroke engine
In the four-stroke engine, the engine cylinder is filled with air and fuel in the gasoline engine through the intake stroke and the piston moves downwards.then the intake
valve is closed and the piston is turned up so the mixture is compressed and the compression stroke completed
The #spark plug ignites the start of the combustion of the mixture so we get high pressure and temperature inside the combustion chamber – see the ignition system in petrol engine
The mixture of hot combustion gases is expanded by applying pressure to the piston and causing the piston to move downward during the work stroke,
The working stroke ends with the piston reaching the lower dead point
The exhaust stroke begins with the piston movement up, the exhaust valve opening and the release of the combustion gases until the piston reaches the upper dead
point
Petrol engines work on #Otto cycle and diesel engines work on #diesel cycle – See the thermodynamic cycles
The engine consists of one cylinder or several cylinders whose ignition is arranged so that regular torque and capacity can be obtained and the vibration reduced as
much as possible
