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.
Does a plane consume more or less fuel with a headwind?
It would consume more fuel - as it would need to expend more energy to fight against the headwind.
What mixture is air?
All combustion engines, require an air/fuel ratio, 14.3 air to 1 part air is the most fuel effiecent for gas engines. Diesels can run more lean, A higher air /fuel under light load. Getting better fuel economy.

Is it true that big car engines waste fuel as compared to small engines what is th e significance of sfc?
Yes. Bigger engines waste more fuel because it take more fuel to make them run.
What does a big engine do for a car?
Generally speaking bigger engines have more power (BHP) than smaller ones. This doesn't mean the car will be faster than a car with a smaller engine however as many other factors come into play. Bigger engines are also more likely to consume more fuel.
Why does a small lightweight car generally have better fuel economy than a big heavy car?
Smaller cars generally weigh less and have smaller more fuel efficient motors where as larger cars generally have larger motors and weigh substantially more. More weight equals poorer gas mileage and larger engines consume more fuel.
Do vehicles consume more fuel in summer than winter?
both
Are diesel engines more polluted than steam engines?
Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient. However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.
How are cars made more fuel efficient?
Lighter weight, more aerodynamic, and more fuel efficient engines, transmissions, and tires.
Why thus the compression ignition engines produce fewer emissions?
Compression ignition engines can easier be made to run lean, meaning they'll havemore air than what's actually needed for the amount of fuel that's present. With excess air,(and higher temperature) it's easier to get more of the fuel burnt. With more of the fuel burnt, there's less unburnt fuel being vented as exhaust, meaning fewer emissions.
What engine fuel is used in airplanes?
Airplane engines use jet fuel. Read more, below.
