A car operates through a complex system of mechanical and electrical components that work together to provide locomotion.the car's electrical components. The battery provides the initial electricity needed to start the car and power systems like lights and the radio when the engine is off. The alternator generates electricity as the engine runs, charging the battery and powering the car's electrical systems during operation. This system is essential for starting the car, operating the headlights, dashboard instruments, and other electronics.

Exactly! Gasoline cars rely on spark-ignited internal combustion engines, distinct from the compression-ignited systems found in diesel vehicles. With spark ignition, fuel is injected into the combustion chamber, where it mixes with air. The crucial moment happens when a spark from the spark plug ignites this air/fuel mixture, initiating the combustion process.
