Internal Combustion Engines
Internal combustion engines are the most common type of engines used in vehicles. They work on the principle of combustion of fuel inside a combustion chamber to generate power. There are two main types of internal combustion engines: four-stroke engines and two-stroke engines.
Four-stroke engines go through four stages – intake, compression, combustion, and exhaust – to complete one cycle. In the intake stage, the fuel-air mixture enters the combustion chamber. During the compression stage, the mixture is compressed, increasing its temperature and pressure. Next, in the combustion stage, a spark ignites the mixture, causing it to burn and release energy. Finally, in the exhaust stage, the burned gases are expelled through the exhaust valve.
On the other hand, two-stroke engines go through two stages – compression and combustion – per cycle. In the compression stage, the fuel-air mixture is compressed, similar to the four-stroke engine. However, in the combustion stage, the mixture is ignited as it enters the combustion chamber, eliminating the need for separate intake and exhaust strokes. This design allows for a simpler construction and higher power output.
“Four-stroke engines offer better fuel efficiency, lower emissions, and smoother operation compared to two-stroke engines, but they are also more complex and tend to be larger in size.”
Both four-stroke engines and two-stroke engines have their own advantages and disadvantages. Four-stroke engines offer better fuel efficiency, lower emissions, and smoother operation compared to two-stroke engines, but they are also more complex and tend to be larger in size. Two-stroke engines, on the other hand, are simpler, smaller, and provide higher power-to-weight ratios. However, they tend to produce more emissions and have higher fuel consumption.

|---|---|---|
| Four-Stroke Engines | Better fuel efficiency | Complex construction |
| Two-Stroke Engines | Higher power-to-weight ratio | Higher emissions and fuel consumption |
Hybrid Engines
In the world of automotive technology, hybrid engines have gained significant popularity due to their ability to combine the power of an internal combustion engine with the efficiency of an electric motor. These engines offer a range of benefits, including improved fuel economy, reduced emissions, and enhanced overall performance.
There are different types of hybrid engines available, each with its own unique characteristics. One type of hybrid engine combines an internal combustion engine with an electric motor, where the internal combustion engine serves as the primary power source and the electric motor provides additional support. This configuration allows the engine to optimize power delivery and maximize efficiency.
Another type of hybrid engine is the plug-in hybrid engine, which can be charged from an external power source. With these engines, the electric motor can operate solely on electric power, offering zero-emission driving for shorter distances. When the battery charge runs low, the internal combustion engine takes over, ensuring a seamless transition and extended range.
Types of Hybrid Engines:
