Combustion Engines

A cross-section of an internal combustion engine reveals its key components, including the cylinder, piston, crankshaft, and valves. During the engine cycle, air and fuel mix enters the cylinder, where the piston compresses it before a spark ignites the mixture, causing an explosion that drives the piston down. This linear motion is converted into rotational motion by the crankshaft, powering the vehicle. The engine also features intake and exhaust valves, which regulate the flow of air-fuel mixture in and exhaust gases out during different phases of the cycle.

In a petrol engine, air and fuel are mixed in the intake system before entering the combustion chamber, allowing for a homogeneous mixture that ignites with a spark plug. In contrast, a diesel engine draws in air alone during the intake stroke, compresses it to a high pressure and temperature, and then injects fuel directly into the combustion chamber, where it ignites due to the heat of the compressed air. This difference in mixing and ignition methods contributes to variations in efficiency, power output, and emissions between the two engine types.

Internal combustion engines (ICEs) continue to be used primarily due to their established infrastructure, affordability, and convenience. They offer a wide range of vehicles with varying performance options and are often more accessible to consumers in terms of purchase price and refueling availability.
