A 4-stroke petrol engine is a type of internal combustion engine that uses a combination of air, fuel, and spark to generate power. The engine operates on four distinct strokes: intake, compression, power, and exhaust. During the intake stroke, air and fuel are drawn into the cylinder through the intake valves. The air-fuel mixture is then compressed by the piston during the compression stroke, preparing it for ignition. The power stroke occurs when the spark plug ignites the compressed air-fuel mixture, causing the piston to move downward and rotate the crankshaft. Finally, during the exhaust stroke, the piston moves upward again, pushing the exhaust gases out of the cylinder through the exhaust valves. The crankshaft converts the up-and-down motion of the pistons into rotary motion, which is then transferred to the wheels of a vehicle or other machinery.

A 2-stroke petrol engine is a type of internal combustion engine that completes a power cycle in two strokes of the piston: up and down. In a 2-stroke engine, the intake and exhaust processes occur simultaneously, and the engine does not have valves like a 4-stroke engine. Instead, the intake and exhaust ports are integrated into the cylinder walls. Here's how it works: during the upstroke, the piston compresses the air-fuel mixture in the cylinder, and the spark plug ignites it, producing power. At the same time, the exhaust port is uncovered, allowing the exhaust gases to escape. During the downstroke, the intake port is uncovered, allowing a new air-fuel mixture to enter the cylinder, and the process repeats. This process allows a 2-stroke engine to complete a power cycle in just two strokes, making it more compact and lighter than a 4-stroke engine.

A 2-stroke diesel engine is a type of internal combustion engine that completes a power cycle in two strokes of the piston: up and down. Unlike a 2-stroke petrol engine, a 2-stroke diesel engine does not use a spark plug to ignite the fuel. Instead, it relies on the heat generated by compressing the air in the cylinder to ignite the fuel. Here's how it works: during the upstroke, the piston compresses the air in the cylinder to a very high pressure, generating a significant amount of heat. At the top of the stroke, fuel is injected into the cylinder through a fuel injector, and the heat generated by the compressed air ignites the fuel, producing power. During the downstroke, the exhaust ports are uncovered, allowing the exhaust gases to escape, and the process repeats.
