Difference between petrol engine and diesel engine:
In this article we will discuss about the difference between petrol engine and diesel engine. The detailed explanation about petrol engine and diesel engine is as follows.
Petrol engine:
- Petrol engine is a internal combustion engine.
- Petrol engine ignites the fuel with the help of a spark plug.
- It has less compression ratio than a diesel engine.
- Torque produced at lower speeds is less than diesel engines.
- In these engines, there is a chance for pre-ignition.
- Due to less torque produces at low gears these engines are not useful to carry heavy loads.
- Overall power developed is less.
- This engines has higher acceleration.
- Maintenance of petrol engine vehicles is lower than diesel engines.
- There is a chance in damaging of the lubrication system.
- Engine temperature increases to high temperature than diesel engines.
- This engines produce less noise.
- The efficiency of the fuel is less comparatively.
- Life of petrol engine is less than diesel.
- Manufacturing of petrol engine is complex due to an additional spark plug is required.
- This type of engine has less weight than diesel.
- Vibrations developed is less in these engines.
- Petrol engine gives less millage.
Diesel Engine:
- Diesel engine is also an internal combustion engine.
- Diesel engine ignites the fuel with high compression only.
- It has a high compression ratio than a petrol engine.
- It develops high torque at lower speeds.
- In this type of engines, there is no chance for pre-ignition.
- Diesel engines are mostly used for carrying heavy loads due to high torque produced.
- Overall power developed is high.
- This type of engine has a lower acceleration.
- Maintenance of diesel engines is more than petrol engine.
- There is no chance in damaging of the lubrication system.
- Diesel Engine temperature is maintained low than petrol engines.
- This engines develops more noise.
- Efficiency of fuel is more.
- Diesel engine has longer life than petrol engine.
- Manufacturing of diesel engines is not as complex as petrol but they should be stronger than petrol engines.
- Due to the diesel engines are strongly built they have more weight.
- Vibrations developed is more due to high compression.
- Millage given by this type of engines is more.
