Overall each piece is bigger and heavier.
Due to the increase in the compression ratio of a diesel which fires on compression rather than spark, the engine is built much stronger than a petrol engine. It therefore just costs more to manufacture.
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
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.
No, diesel engines cost more to build than petrol engines. They are built much heavier.
Yes
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.
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.
first of all its engine. ADVANTAGES - petrol is cheaper than diesel so cheaper to run. petrol cars generally cost less than diesel (a few 1000). petrol engines are usually faster than diesel off the line and have a higher top speed than a diesel car with the same sized engine. DISADVANTAGES - petrol is less economical than diesel and also diesel cars are much better for over taking than petrol as it has more torque (pulling power)
for same power diesel engine produces more torque @ less rpm whereas petrol engine produces less torque @more rpm this difference is due to different combustion processes of diesel and petrol
Diesel engines fire on compression rather than spark. This requires that a diesel engine be made much stronger than a petrol engine. All internal components are made to much stronger specifications. A petrol engine could not handle the higher compression and would self destruct.
No, diesel does not mix with petrol. Diesel is a heavier fuel with a different chemical composition than petrol (gasoline), which can lead to engine damage if mixed. Using diesel in a petrol engine can cause serious performance issues and potential engine failure. It's important to use the correct fuel type for your vehicle.
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.
