- Pistons: There are typically four pistons in a 1-litre engine, each moving up and down within its own cylinder.
- Piston rings: Each piston has multiple piston rings that help seal the combustion chamber and control oil consumption.
- Connecting rods: The connecting rods connect the pistons to the crankshaft, converting the reciprocating motion of the pistons into rotational motion.
- Crankshaft: The crankshaft is the main rotating part of the engine and converts the reciprocating motion of the pistons into rotational motion that is transmitted to the wheels.
- Camshaft: The camshaft controls the timing of the valves in the engine, opening and closing them at the appropriate times.
- Valves: There are typically four valves per cylinder (two intake valves and two exhaust valves), which control the flow of air and fuel into and out of the combustion chamber.
- Spark plugs: There is typically one spark plug per cylinder, which provides the spark to ignite the air/fuel mixture in the combustion chamber.
In addition to these main components, there are numerous other parts and systems involved in the operation of a 1-litre engine, including the fuel injection system, cooling system, lubrication system, and various sensors and electronic control modules. The exact number and configuration of these components can vary depending on the specific engine design.
