Differences: first, the fuel used is different. Diesel engines use diesel as fuel, gasoline engines use gasoline as fuel; Second, ignition methods are different. The ignition mode of diesel engine is compression ignition and that of gasoline engine is ignition. Third, cylinder diameter size is different. Diesel engine cylinder diameter is larger, generally 65300 mm, gasoline engine cylinder diameter is smaller, generally 32101 mm; Fourth, different speed. Diesel engine speed is low, generally 15002400 RPM, gasoline engine speed is high, generally 3000_6000 RPM.
Their advantages and disadvantages: diesel engine reliable work, can work continuously for a long time, long life, fuel consumption rate is low, the use of good economy, there is a certain power reserve can adapt to short-term overload work, but the general weight is large, noise is also large. Gasoline engines have low weight, low noise and low vibration, but poor fuel consumption and economy.
Scope of application: Diesel engines are generally used in tractors, agricultural transport vehicles, drainage and irrigation and agricultural and sideline products processing machinery, trucks, construction machinery, combine harvesters, etc. The gasoline engine is mainly used in automobile engine, motorcycle engine, tractor starter, small generator set, plant protection machinery, tea picking machine and so on.
