What is the difference between the petrol engine and diesel engine?
The primary difference (as most of you already know), is that petrol engines use spark plugs to ignite the air-fuel mixture, while diesel engines rely on heavily compressed air without any spark plugs.
Which is better between petrol and diesel engine?
When it comes to efficiency, diesel engines provide more efficiency by using 15-20% less fuel compared to petrol engines. The low-end torque of diesel engines provide a much better highway driving experience. However, the price of this efficiency is a higher premium compared to the petrol variant of the same car.
How can you tell the difference between petrol and diesel?
Diesel or petrol car: How can I tell?
- Look for a sticker. Rental companies often put stickers in different places around the car to tell you which fuel to use.
- Check the model name. There might be a clue on the back of the car itself.
- See if the fuel pump will fit.
Which part is not common between petrol and diesel engine?
Detailed Solution
| Petrol engine | Diesel engine |
|---|---|
| Less vibration, and hence, smooth running. | More vibration, and hence, rough running and noisier. |
| Engine weight is less. | Engine weight is more. |
| It emits carbon monoxide. (CO) | It emits carbon dioxide. (CO2) |
Which is more costly diesel or petrol?
When it comes to cost while buying the car, a diesel variant is relatively more expensive than the petrol variant consisting of the same specifications. The cost difference can range from 50,000 to 1 lakh.
Why is diesel cheaper than petrol?
Even in India, the base price of diesel has been higher than petrol. However, diesel has always been cheaper because it is used by farmers along with truck and bus fleets. Thus, to reduce the burden on farmers and transport fleet operators, diesel is priced lower than petrol in India.
What colour is diesel fuel?
Gasoline is naturally clear, white, or slightly amber. Diesel comes out clear or yellow. But fuels in Canada and around the world is dyed various colours to clearly distinguish it for special purposes.
Which is a common component between Petrol and diesel engine?
Exhaust silencer battery and fuel injector are parts of both Petrol and Diesel engines.
Which cycle is more efficient?
Otto cycle
Explanation: Otto cycle is more efficient than Diesel cycle for a given compression ratio. 6. For constant maximum pressure and heat input, the air standard efficiency of the gas power cycle is in the order.
What are the benefits of diesel over petrol?
Diesels are more fuel efficient than petrol engines and emit less CO2, which makes them better for the environment. Diesels produce considerably more torque (pulling power) than their petrol counterparts, which makes them good engines for towing or carrying heavy loads – ie: seven occupants – on a regular basis.
