The process of converting fuel energy into mechanical energy in an engine begins when gasoline is combined with air in a device known as a carburettor, resulting in a highly combustible combination. Induction stroke: The piston is depressing as it descends, the inlet valve is fully open, and the exhaust valve is completely closed.
During the intake phase of a spark-ignition engine, the fuel and air are mixed together and then introduced into the cylinder by the spark. Following compression of the fuel-air combination by the piston, the spark ignites the mixture, resulting in combustion. During the power stroke, the piston is propelled forward by the expansion of the combustion gases.
How does a car start?
When a car is first started, the battery provides all of the energy (electrical) required.When the engine is turned on, the alternator begins to generate enough electricity to operate the engine and begin charging the battery at the same time.You will observe that the charge meter (if you have one) will display a significant amount of positive charge immediately after starting the engine.This is normal.
How does the electrical system of a car work?
The electrical system is made up of two components: a battery and an alternator. Through a belt, the alternator is connected to the engine and creates power that is used to replenish the battery.
