They put out more torque per cubic inch, and certain ones can get better miles per gallon, but the fuel is also more expensive.

Modern diesel engines are more efficient than their gasoline counterparts.

Which engine is more efficient diesel engine or gasoline engine?

Diesel engines are more efficient than gasoline engines.


Which is more powerful petrol or diesel engine?

Normally Diesel engines produce more torque than gasoline engines but less horsepower. Gasoline engines rev up quicker and produce higher horsepower at higher rpms. Diesel engines develop their higher torque at lower rpms which allows a diesel to carry a heavier load.


What is the difference between diesel and gasoline engines?

Diesel engines ignite fuel through compression, while gasoline engines use spark plugs. Diesel engines are more fuel-efficient and have higher torque, but gasoline engines are typically quieter and have faster acceleration.


Are diesel engines more reliable than gasoline engines?

Yes, diesel engine will last much longer than gasoline engines. They are built much stronger but are also more expensive to build.


What is the difference between gasoline and diesel fuel?

Gasoline and diesel fuel are both types of fossil fuels used to power vehicles, but they have different chemical compositions and properties. Gasoline is lighter and more volatile, igniting easily in spark-ignition engines. Diesel fuel is heavier and less volatile, requiring higher compression in diesel engines to ignite. Diesel engines are more fuel-efficient but produce more pollutants than gasoline engines.


Which gives more mileage petrol or diesel?

Diesel engines normally get better fuel economy than gasoline engines.


Is diesel gasoline a mixture?

No, diesel fuel is not a mixture of gasoline. Diesel fuel is a specific type of fuel that is heavier and less volatile than gasoline, and is used primarily in diesel engines. Gasoline, on the other hand, is a lighter and more volatile fuel that is used in spark-ignition engines.


What is the difference in how a normal car engine and a diesel car engine in how they work?

diesel engines compress the fuel mixture much more than gasoline engines, diesel engines are always fuel injected while gasoline engines have the option of being carbureted, diesel engines usually cost more, diesels produce more power than a comparable gasoline engine, diesel engines have no distributor or spark system, and instead use glow plugs to ignite fuel, and diesel engines can be converted to run on vegetable oil with few modifications.


Why do diesel engines have more torque than gas engines?

Engines with longer piston stroke, higher turbo boost pressures, and diesel fuel has more energy in it than gasoline.


Why are diesel engines loud?

Diesel engines detonate. Diesel has more potential energy than gasoline, instead of burning evenly, diesel explodes creating a knock or rattle noise.


What are the key differences between unleaded and diesel fuel, and how do these differences impact vehicle performance and efficiency?

Unleaded fuel is used in gasoline engines, while diesel fuel is used in diesel engines. The main difference is in their ignition process: gasoline engines use spark plugs to ignite the fuel, while diesel engines rely on compression to ignite the fuel. This difference affects performance and efficiency, as diesel engines typically have higher torque and better fuel efficiency compared to gasoline engines. Diesel fuel also has a higher energy density, which can result in better mileage for diesel vehicles. However, diesel engines tend to produce more emissions than gasoline engines.


What are some of the advantages of having a diesel truck?

Diesel trucks can pull heavy loads because of the all the torque generated. Diesel is also more efficient than gasoline. Diesel engines are durable and last longer than gasoline engines. Diesel gas is also cheaper to refine.
