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.

∙ 12y agobecause high higher compression ratios used in the diesel engines their thermal efficiency is higher than the petrol engines and therefore their running cost is lower.

Why is diesel environmentally friendly?
Diesel is not entirely envionmentally friendly. It is just more friendly than petrol as it requires less refining and, due to advancements in technology, can burn cleaner than petrol in engines.
Why is petrol more efficient than ethanol?
Petrol is more efficient as a fuel than ethanol, because the energy generated by burning a fuel is primarily released by formation of bonds between oxygen and carbon or hydrogen. One such bond already exists in an ethanol molecule, whereas in petrol few or no such bonds exist.
What temperature does petrol freeze at?
Petrol is not a single chemical compound so it doesn't have a sharp freezing point.
What is the amount Difference between high sulfur and low sulfur diesel?
There is not a clear cutoff point between "high and Low sulfur diesel". Ultra low sulfur diesel ULSD is what is currently required for on road use. ULSD can contain no more than 15 ppm sulfur (15 micrograms sulfur per gram of fuel or 0.0015 wt.%). Low sulfur diesel would contain more sulfur than ULSD and high sulfur diesel more than low sulfur diesel.
What is the cleanest burning fuel?
(Although biofuel is Earth-friendly and easy to use . . . ) The most efficient fuel, in terms of the amount of energy per unit volume, is diesel, followed by jet fuel (kerosene). Biodiesel follows, then gasoline. Ethanol (as corn-based alcohol) is much farther down the list. Fuels rated by weight, however, are on a different efficiency scale. Liquid hydrogen contains far and away the most energy per kilogram. Then come jet fuel, gasoline, and ethanol. A table of fuel efficiencies can be found at the Related Link.
Why diesel engine is costlier than petrol engine?
Overall each piece is bigger and heavier.
Why diesel engine car is costlier than petrol engine car?
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.
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.
Why diesel cheaper than petrol?
In the United States diesel is not cheaper than petrol or gasoline, it is higher.
Is petrol heavier than diesel?
No, diesel is heavier.
How do you tell petrol from diesel in a can?
Petrol is and bit more vicous and that diesel is a lot darker than petrol. Petrol burns quicker when set alight, however diesel burns more brightly!
What is the different between petrol and diesel?
The difference is that diesel is more oily than petrol, and is cheaper to produce.
Why do petrol cars steam more then diesel cars?
because petrol is easer to burn than diesel
Are diesel and petrol shocks the same?
Depends on the car, if a car has petrol and diesel version than yes
What is the adventages and disadvantages of petrol engion?
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)
Does petrol or diesel cost more?
diesel is usually more expensive but diesel cars usually have more mpg than petrol cars
How can oil company solve the problem of the demand of diesel and petrol?
Produce more petrol than diesel. :P
