Difference Between Petrol Engine and Diesel Engine ?

Hello friends, today I am going to tell you Difference between petrol engine and diesel engine: If you also want to know, then keep reading this article completely.

Knowing the Difference between petrol engine and diesel engine is very important because with this you can buy a vehicle according to your need, before we understand what is a petrol engine? And what is a diesel engine? know about.

What is Diesel Engine?

Fuel is required to run the engine and the engine in which diesel is used as fuel to run that engine is called diesel engine.

What is a petrol engine?

The engine in which petrol is used as fuel is called petrol engine.

Difference Between Petrol Engine and Diesel Engine

We have come to understand what is petrol engine and what is diesel engine. Now we will know the difference between Diesel Engine and Petrol Engine –

No. Petrol Engine Diesel Engine
1. These engines work on auto cycle. These engines work on diesel cycle.
2. In these there is suction of mixture of air and petrol. There is only air suction in it.
3. A carburetor is needed to send the mixture of air and petrol to the cylinder. Injector is used to send fuel to the cylinder.
4. Sparking plug is required for combustion of fuel. The combustion of fuel occurs due to the high temperature of the air produced due to compression.
5. Compression ratio is low (from 5 to 8). Compression ratio is high (from 12 to 20).
6. For more power and higher efficiency, the mixture cannot be pressurized to high pressure as there is a risk of ignition before both air and fuel are present. There is no fear of pre-ignition because only air is present in the compression stroke. Therefore, more power and efficiency can be obtained by compressing the air to a higher pressure.
7. It is difficult to send the correct amount of fuel to the engine cylinder. Due to the fuel pump, only the right amount of fuel reaches the cylinder.
8. Due to less pressure difference in the cylinders, these engines reduce noise. Due to the high pressure difference in the cylinders, these engines make more noise.
9. These engines are light due to low compression ratio. These engines are stronger and heavier due to higher compression ratio.
10. Only two valves are used in these. Three valves are used in these. The third valve is in the form of an injector.
11. The starting cost of the engine is low. The initial cost of the engine is high.
12. Since petrol is more expensive, their operating cost is high. Diesel, being cheaper than petrol, has lower operating cost.
13. The speed of these engines is high. (from 2000 to 5000r.p.m.) The speed of these engines is less. (from 400 to 1500r.p.m.)
14. The temperature of engine cylinders remains low. The temperature of the cylinders remains high.
15. The engine can be started quickly when it is cold or even in winter. When the engine is cold, it runs late in winter.
16. In these, the spark plug gets damaged very quickly.  In these, the injector is rarely damaged.
17. Engine repair has to be done quickly. Engine repairs have to be done after a long time.
18. Due to the high torque, the transmission has to be made stronger.  Due to the low torque, the grinding does not have to be made very strong.
19. Fuel consumption is high. Fuel consumption is less.
20. These engines are used in light vehicles like scooters, motorcycles, cars, jeeps etc. These engines are used in heavy vehicles. Like Bus Tuck, Tractor etc.

FAQ’s
