suresh When diving into the Automobile Engineering domain, it's crucial to understand the fundamental dissimilarities between a four-stroke engine and a two-stroke engine.
### Four-Stroke Engine:
In a four-stroke engine, the combustion process occurs over four distinct strokes of the piston: intake, compression, power, and exhaust. This design provides better fuel efficiency and power output compared to its two-stroke counterpart. Additionally, four-stroke engines produce lower emissions, making them environmentally friendly.
### Two-Stroke Engine:
Contrarily, a two-stroke engine completes the combustion process in just two strokes of the piston: compression and power. While simpler in design and typically lighter, two-stroke engines tend to deliver higher power-to-weight ratios. However, they are less fuel-efficient, produce more emissions, and require a mixture of oil and fuel for lubrication.
Overall, the difference lies in the number of strokes required to complete the combustion cycle, affecting performance, efficiency, emissions, and maintenance requirements of the engine.
