By a generous estimate, they can be about 30% more efficient than a gasoline engine.
I assume you mean "are turbines more efficient than piston engines".
Depends on the running conditions. At full load, steady running conditions, turbines are better than piston Engines. At varying loads, turbines often do quite poorly.
Diesel engines are more efficient than 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.
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.
Diesel engines are more efficient. They get better mileage, produce more torque, and last much longer than a gasoline engine. They are also more expensive to build.
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.
Diesel engines are more efficient than gasoline because chambers are different. A diesel engine has better gas mileage.
Because different engines have different advantages. Steam engines can be run from anything that burns, but are big and heavy. 2-stroke (gasoline) engines has great power-to-weight ratio, but tend to use a lot of fuel and create a lot of emissions. 4-stroke Diesel engines tend to run rougher and don't rev as high as gasoline engines but are more fuel efficient and often have more torque.
Diesels are more efficient than gasoline engines because of the way engine speed is controlled (diesels control speed with the amount of fuel injected, whereas gasoline engines control speed by how much air gets in), and because diesel fuel contains more chemical energy than gasoline.
Yes, diesel engine will last much longer than gasoline engines. They are built much stronger but are also more expensive to build.
Electric cars do not have a traditional internal combustion engine like gasoline cars. Instead, they have an electric motor powered by a battery. This motor converts electrical energy into mechanical energy to drive the car, making it more efficient and environmentally friendly compared to gasoline engines.
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.
The diesel is more efficient but more expensive to build.
