What is the difference between petrol and diesel engines?
diesel engines doesn't use spark plug but uses heater plug.petrol engines produces more torque than petrol engines but petrol engines produces more acceleration than diesel engines.petrol engine is faster to be heated than diesel engine.
Which is more powerful petrol or diesel engine?
Normally Diesel engines produce more torque than gasoline engines but less horsepower. Gasoline engines rev up quicker and produce higher horsepower at higher rpms. Diesel engines develop their higher torque at lower rpms which allows a diesel to carry a heavier load.
Why diesel engines are preferred over petrol engines in agricultural fields?
More torque, less maintenance, longer engine life, and uses less fuel.
Which is rated better diesel or petrol engine?
Each engine is rated better for different things. A petrol engine generally has a higher horsepower than a diesel engine, so acceleration and speed is often better on a petrol engine. Diesel engines tend to rate better with torque, so they are better at pulling heavy loads, which is why diesel engines are used in trucks and locomotives.
Does a diesel have more power than a gas motor?
A diesel has more power and torque at lower revs. Petrol engines need higher speed to develop power.
Why do many cars have diesel engines when petrol gives a better performance?
Some cars have diesel engines because diesel engines give more mileage and diesel is cheaper than gasoline in some countries. In the UK diesel fuel costs more than gas but, because diesel engines give much better mileage (miles per gallon), people are still happy to pay more for the diesel fuel if they run diesel vehicles. Diesel engines last much longer and have much better torque at low revs than a petrol engine.
What is the difference in bhp between petrol and diesel engines?
Both our internal combustion engines but the main difference is that a petrol engine uses spark plugs to ignite the fuel but a diesel engine has no spark plugs but instead uses compression to ignite the fuel. A diesel engine is also built much stronger than a gasoline/petrol engine. Diesel engines get better fuel mileage, last longer, and have much more torque or pulling power than a petrol engine. The only disadvantage to a diesel is the fact that it is more costly to build than a gasoline engine.
What is difference between a diesel and petrol engine?
Basically diesel engines are much higher compression giving them more torque also the fuel is ignited by compression not a spark like in a gas engine
Why is petrol rate costlier than diesel?
Diesel and petrol engines work differently. Diesel engines use compression to ignite the air/fuel mixture, and have a much higher compression ratio than petrol engines, which use spark ignition. The conditions for ignition are not met when petrol is put into a diesel engine, and will stall.
Does a double decker bus use petrol or diesel?
Well this all depends on what type of engines are supplied in these buses. Usually buses use diesel due to the high weight load that that are put on the engines. Diesel engines have better compression and can usually provide more torque to do work with all those people on board. Here is a good read on Diesel engines....(link)
Why petrol engines are faster than diesel engines?
Petrol engines are widely considered to be the most efficient of engines, because they are more refined than diesel. Since diesel is not completely refined, it cannot completely combust and so does not (in theory) produce as much energy per litre of fuel as a petrol engine. However, some diesel engines can be made to be much more efficient than petrol engines because they have a different type of fuel, and burn it in a different way.

Is diesel or petrol more efficient?
Diesel engines are more efficient. They get better mileage, produce more torque, and last much longer than a gasoline engine. They are also more expensive to build.
