Diesel engines produce high torque than gasoline engines.
Answer to Problem 9.1E
Diesel engines produce more torque as a result of a higher compression ratio (longer stroke and turbocharger), which results in greater acceleration off the line. This acceleration, though, is only fleeting because the torque in diesel cars is dispersed over a much smaller region and their power band is considerably smaller.
Explanation of Solution
Torque:-
The force that can cause an object to rotate along an axis is measured as torque.
Diesel-Engine:-
Diesel engines work by compressing and heating air to a high pressure and temperature before injecting a little amount of fuel into it.
Gasoline- Engine:-
A gasoline engine creates combustion by injecting a mixture of air and fuel into the cylinders.
Reason:-
- The diesel engine's longer strokes enable the piston to be moved farther, generating more force.
- The amount of torque generated by the wheels increases as cylinder pressure increases.
- High Compression Ratio, which is just the ratio between the cylinder's highest and minimum volumes.
- Compared to comparable gasoline engines, turbo-diesels typically operate at greater turbocharger boost settings.
- The amount of torque acting through the crankshaft increases as more energy is transmitted through to pressure on the piston with each combustion of diesel.

- A comparison between the actual gasoline engine and actual diesel engine is to be made. Assume the heat added is the same. Check all that apply. Group of answer choices Because the diesel engine has a lower compression ratio the thermal efficiency will be higher because less work is required to compress the air. Because the diesel engine can run a higher compression ratio the thermal efficiency will be higher. Because the diesel engine has a higher efficiency, it reponds quickly to rapid accelerations and in-city driving conditions compared to a gasoline engine. The diesel engine compresses only air on the compression stroke and is not knock limited so the compression ratio can be much higher The gasoline engine is knock limited and the compression ratio will be lower than the diesel engine The gasoline engine compresses only air on the compression stroke and is not knock limited so the compression ratio can be much higherarrow_forward1.)
