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.
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.
No, diesel engines cost more to build than petrol engines. They are built much heavier.
Diesel engines have much more torque at low rpm.
Diesel engines normally get better fuel economy than gasoline engines.
Batteries are basically the same for petrol or deisel engines, but diesel engines require more cranking force and demand a bigger battery. So a battery from a diesel engine is ok for petrol, providing it fits.
sic difference between Petrol and Diesel engines that the difference of fuel and their mixture..in diesel we only compresses the Air and sprays Diesel but in Petrol Engines we compresses both the air and Petrol together and gets burnt with the the help of spark given by the Spark plug. I must add this, also the thermodynamic cycle is so different in diesel engines rather than petroleum engines. You can fined more in Reed's series volume 12
Diesel engines are more efficient and do use less fuel, but they do not cost less than a petrol engine, they cost more. Diesel fuel also costs more. A diesel engine will however last longer.
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.

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.
the engine will not run because of three reasons. 1. Diesel uses more compression than the petrol engine does 2. the diesel engines fuel to air mixture is 1:1 and petrol isn't 3. diesel engines use straight compression or glow plugs instead of spark plugs
Diesel fuel is designed for diesel engines, which have a different combustion process than petrol engines. Using diesel fuel in a petrol car can damage the engine components, as diesel fuel may not burn efficiently in a petrol engine, leading to poor performance and potential engine damage. Additionally, modern petrol cars are equipped with fuel systems designed specifically for petrol fuel, not diesel.
