Actually diesel fuel has a slightly lower amount of energy per weight than gasoline (45.3 vs. 47.2 MJ/kg). Cylinder pressure is what gives diesel engines their power, that is why diesel engines parts are so much stronger/heavier than gas similar sized gas engines.

What has more fuel energy petrol or diesel?
Gasoline has more energy per lb than Diesel.
Why diesel gives more milage than petrol and petrol car costly than diesel?
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.
Why cant you use diesel in a petrol car?
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.
Is a diesel vehicle more economical than petrol vehicle?
Yes, they will use less fuel but the fuel they use is more costly. A diesel vehicle also costs more than the same vehicle equipped with a petrol engine.
What would happen if we ran out of fuels such as petrol and diesel?
Without petrol (gasoline) and diesel fuel, we would be forced to use other forms of energy. We would rely more on solar energy, wind, human energy, geothermal energy, and nuclear energy. If we were in close danger of running out of fossil fuels, we could transition to using other forms of energy.
Which gives more mileage petrol or diesel?
Diesel engines normally get better fuel economy than gasoline engines.
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.

Why does a petrol engine have more power than a diesel engine?
A petrol engine revs higher, which allows it to burn more fuel and output more power.
Which is the engine that gives max mileage either diesel or petrol engine?
Diesel will always give you better fuel mileage as diesel fuel itself contains more BTU (the measure of thermal energy) in a given quantity than compared to gas.So therefore a diesel engine can extract more mileage out of a gallon of diesel fuel as there is more energy to extract out of that gallon as compared to a gallon of gas.Considering this, this is why diesel fuel prices would have to rise considerably over gas before the two would be equal on a cost per mile basis.
Which is best engine a petrol or a diesel?
They each have their pros and cons. The Diesel will last longer, use less fuel, and has more pulling power or torque. The petrol is cheaper to build, fuel cost less, and is cheaper to repair.
What is more combustible diesel or petrol?
Petrol is far more comustile compared to Diesel
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.
