Higher compression ratio, therefore it develops far more torque which equates to pulling power.

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.


How does a diesel locomotive develop power?

A diesel locomotive is actually a hybrid engine. The diesel engine generates electricity, which is transferred from a motor to the wheels.


Why is petrol engine RPM is greater than diesel engine?

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


When petrol is mixed with a diesel engine?

When petrol is mixed with diesel engine the engine will not start due to the following reasons;Fuel in diesel must be compressed at 400o and above to approach compression power while petrol start at 150oPetrol have lower density than that used in diesel enginePetrol use spark ignition lather pressure ignitionPetrol have different octane number than that used in diesel enginePetrol fuel cannot produce much power as that produced in diesel engine with real diesel fuel.Will not accomplish diesel engine phases

What is diesel and petrol used for?

diesel and petrol are source which is used to generate power.


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.


Why diesel engine has more efficiency than petrol engine?

Diesel is a more combustible fuel than petrol, therefore less fuel is required to generate the same power as petrol. This also means that spark plugs aren't required, like in a petrol engine, since the diesel will ignite off engine compression alone. This also makes the engine arguably more reliable since there are less parts, and less things to go wrong.


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)


Is there more power in petrol engine than diesel engine?

There is more energy in one gallon of diesel than one gallon of gasoline. To elaborate, the word "petrol" is defined in different ways in different places..... but if you have two internal combustion engines of the same displacement the diesel will produce more power than the gasoline engine, especially in 'torque' measurement


What is a diesel electric loco?

A diesel-electric loco - is basically a train engine. The diesel engine turns an alternator, which generates electricity to power the motors which drive the wheels.... WHY was this posted in the Cakes, Chips and Sandwiches sections !


Who is better gasoline engine or diesel engine?

diesel. Diesel engines tend to have better efficiency especially at less than full load. Gasoline/Petrol and LPG engines tend to have better power weight ratios.
