1) Gasoline engines:
- Fuel: Gasoline
- Spark Ignition: Gasoline engines use spark plugs to ignite the fuel-air mixture.
- Compression Ratio: Gasoline engines have relatively lower compression ratios compared to diesel engines.
- Efficiency: Gasoline engines are generally less efficient than diesel engines due to lower compression ratios.
- Emissions: Gasoline engines typically produce more emissions, including hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx), compared to diesel engines.
2) Diesel engines:
- Fuel: Diesel
- Compression Ignition: Diesel engines rely on high compression to ignite the fuel-air mixture.
- Compression Ratio: Diesel engines have higher compression ratios than gasoline engines, resulting in better fuel efficiency.
- Efficiency: Diesel engines are more efficient than gasoline engines due to higher compression ratios and complete combustion.
- Emissions: Diesel engines produce fewer HC and CO emissions compared to gasoline engines but may emit more particulate matter (PM) and NOx.
The primary differences between gasoline and diesel engines lie in the type of fuel used, the ignition method, compression ratios, efficiency, and emissions characteristics.
