What is more efficient the gasoline engine or diesel engine?
The diesel is more efficient but more expensive to build.
Why a dieel engine is more efficient than a gasolene engine?
Diesel engines are more efficient than gasoline because chambers are different. A diesel engine has better gas mileage.
Is diesel or petrol more efficient?
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.
Do diesel cars generally cost more than gasoline engine cars?
Diesel cars do tend to cost more in general than gasoline engine cars. The claim on this is that it is more expensive to create and manufacture these vehicles, and due the fact that diesel vehicles are more fuel efficient.
Are diesel cars more efficient than normal cars?
Because of a diesel engines high compression ratio, it will always be more efficient than an equivalent gasoline engine. However, this higher compression ratio requires a heavier, more expensive engine which isn't able to reach as high an RPM as a gasoline engine. It is for these reasons that despite their higher efficiencies, diesel engines are less popular than their lighter, less expensive gasoline equivalents. Diesel cars will provide you with a higher MPG rating compared to a similar gasoline powered engine. The price for diesel fuel is generally higher than the cost of unleaded gasoline.
Which is more efficient otto engine or diesel engine?
diesel cycle
What is the advantage of diesel engine to gas engine?
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.
Why do large vehicles use diesel?
Because it is more efficient than a gasoline engine considering its output torque and power per weight.
How does a diesel engine differ from a gasoline engine?
A diesel engine fires from compression and not from a spark. A diesel engine is also built much stronger than a gasoline engine. Diesel engines normally have less horsepower than a gasoline engine but have much more torc, or pulling power.
Which is more efficient a petrol engine or a diesel engine?
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
Does diesel get better gas mileage than regular gasoline?
In general, yes. The diesel engine cycle utilizes much higher compression than a gas engine. And the higher the compression, the more "efficient" the engine- everything else being equal. Also, diesel has more energy (btu) per gallon that gasoline, so you win on two fronts.
Why does a diesel engine develop more torque than a gasoline engine of equivalent displacement?
Diesel engine runs at a higher compression ratio than a gasoline engine. A typical diesel engine may also use a longer stroke and smaller bore than a gasoline engine. Diesel fuel has a higher energy density than gasoline.
