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
What else can I help you with?
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.
Why is petrol not used in diesel engines or diesel in petrol engines?
Because the engines will not run with the wrong fuel to to their design. Although both diesel and petrol engines are internal combustion engines, they have differences that enable them to use these different fuels. A petrol engine ignites the fuel/air mixture by using a spark plug. A diesel engine in contrast has no spark but compresses air during the compression cycle. When air is compressed it heats up. Diesel is then injected into the cylinder and it ignites.
Which part not common between petrol and diesel engines?
spark plug dude
What are the defferences between dessel and petrol engine?
Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.
Is the petrol engine is costly thab diesel engine?
No, diesel engines cost more to build than petrol engines. They are built much heavier.
What is the difference between petrol and diesel car engines?
there are lots of differences. one no spark plugs. diesel fires by compression and heat gas or petrol requires a spark. the fuel delivery is diffrent to diesel is usally injected under a higher psi to areosol the fuel better. but diesel is more like fuel injection because the valves are diffrent
What is the major difference between a petrol car and a diesel one?
The primary difference between a petrol car and diesel car is the consumption rate - diesel and petrol are refined from mineral oil using differing methods. The result is diesel engines having a lower fuel consumption rate than their petrol counterparts when installed in a vehicle of similar mass. CO2 emissions are also lower in a diesel engine than they are in a petrol engine.
Does diesel have larger molecules than petrol?
Yes, diesel generally has larger molecules than petrol. This difference in molecular size is one of the factors that contribute to the differences in properties between diesel and petrol, such as their boiling points and combustion characteristics.
Which one having high torque petrol or diesel engines?
Diesel engines have much more torque at low rpm.
Which gives more mileage petrol or diesel?
Diesel engines normally get better fuel economy than gasoline engines.
Can you use a diesel battery in place of a petrol battery?
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.
Why Rover 75 starts then wont start?
There are a number of reasons for this, but varies between petrol and diesel. Diesels dont like the cold. The diesel engines in the 75 are BMW common rail engines.
