Q
how a engine starts
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Starting an engine involves a series of steps that require several key components:
1. Battery & Ignition: When you turn the car key or press the start button, the car's battery sends power to the spark plugs in the ignition system.
2. Fuel Injection: The fuel system also becomes active and fuel is injected into the car’s engine.
3. Spark Plugs: The spark plugs utilize the power from the battery to create a spark which ignites the fuel-air mixture that has been injected into the cylinders.
4. Combustion Process: This ignition causes a small explosion in the engine's cylinders, forcing the pistons down. This is also known as the combustion process.
5. Crankshaft Rotation: The downward motion of the pistons turns the crankshaft, which then turns the wheels.
6. Starting the Engine: The whole process takes a matter of seconds. Once started, the engine continues to run, powered by the combustion of fuel until it's either turned off or runs out of fuel.
7. Cooling System: Meanwhile, to prevent overheating, a cooling system (usually a water/coolant mix) circulates around the engine, absorbing excess heat, which is then released via the radiator.
Engines use what is known as a 4-stroke combustion cycle: Intake, Compression, Combustion and Exhaust. This cycle is repeated continuously to keep the engine running once started. The above points are a simplified version of what happens, as engines can be extremely complex machines with many parts all working together.
