What is better petrol or diesel?
Financial: diesel engines are more efficient and use 15−20% less fuel meaning cheaper running costs. ... For newer diesel cars though, tax is typically higher than for petrol. Driving experience: diesel cars offer more low-speed torque which means they have better overtaking power and towing ability.
What is the difference diesel and petrol?
| Difference Between Petrol and Diesel Engine | |
|---|---|
| Diesel Engine | Petrol Engine |
| The fuel is mixed with air inside the cylinder | Air and the fuel are mixed in a carburettor |
| Ignition is achieved with the help of the hot, compressed air. | Fuel is ignited with an electric spark |
| High compression ratio | Relatively low compression ratio |
Which is more dangerous petrol or diesel?
So, while diesel fuel contains slightly more carbon (2.68kg CO₂/litre) than petrol (2.31kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower. ... The fine particulate matter (PM) that diesel engines produce also causes cancer and can have acute respiratory effects.
Why petrol is not used in diesel engines?
We know that, petrol is ignited by spark and diesel is ignited by compression ignition, the volatility of the petrol is greater than diesel. The spark plug produces the spark only at some places, not at all the point of air-fuel mixture. ... This is the reason for Why diesel cannot be used in petrol engine?.
What is the disadvantage of diesel cars?
Cons of diesel cars

Why petrol cars are cheaper than diesel?
New diesel cars cost more by way of tax and depreciation is now slightly higher. On the flip side then, Petrol vehicles are slightly cheaper to buy and service. They have higher CO2 emissions than diesel but produce less of some other emissions. They are quieter but also less efficient and use more fuel than diesels.
Do diesels last longer than petrol?
Diesel engines do last longer than petrol ones. ... While diesel engines typically last longer they are more costly to repair.

Which is faster diesel or petrol?
In petrol engines, on the other hand, the power builds in relation to the revs. ... Though the diesel variant has a higher torque than the petrol, it does so on a lower rpm due to which shifting is necessary sooner than that on the petrol. Thus the petrol produces more power and accelerates from 0 to 100 quicker.
Is petrol cleaner than diesel?
Overall, diesel cars emit less hydrocarbons, carbon monoxide and lead pollution than petrol cars, but produce more noxious gases and significantly more particulates. Despite much debate over which car, petrol or diesel, is cleaner, weighing up the advantages and disadvantages is not easy.
Is petrol a clean fuel?
