piston engines have more torque than jet engines..
Diesel engines have much more torque at low rpm.
that isn't always true. however, smaller engines are made towards higher rpm's. and also rev up faster. larger engines are more for torque, and smaller engines are more compact and for lighter cars.
Horsepower is calculated from RPM and torque. The higher the RPM you can sustain an engines torque at, the higher the Horsepower. Horsepower and Torque are always the same amount at 5250 RPM with all but diesel powered engines. Also the more rotational mass you can spin at a higher rpm, the more energy it poseses.
Torque backup is generally applicable to low speed diesel engines which are primarily used for high torque applications like tractors and off highway vehicles. Generally torque backup is expressed in percentage Torque backup = (max Torque - rated speed torque)/rated speed torque in % This generally means how much the engine can be loaded when its rpm drops to max torque rpm. Usually all OEM try to give maximum backup torque from their engines. But it is limited by volumetric efficiency at lower rpm for NA engines and for TC engines it can be more.
generally , two strokes are smaller capacity , shorter stroke, higher revs. for given engine capacity , long stroke /small bore = high torque / low revs short stroke/big bore = low torque / high revs
The issue is that diesel engines, while they produce a whole lot of torque, cannot rev nearly as high as comparable gasoline engines. And since:horsepower = (torque*engine speed) / 5252If your engine won't rev past 3000 rpm, you'll always have less peak horsepower than torque. As for why they can't rev higher, they're limited by either the burn rate of the fuel per ignition stroke, the mechanical limitations due to the longer piston rods/crank lobes, or both.

Depends on the engine.
in steam engines, the steam has to be compressed, which needs less torque than the internal combustion engine, where fuel air mixture is compressed Hence, the case!
18 ft/lbs. Which is typical for Cummins engines. To be honest, I've always just gone "tight is tight" for all of them - Cat, Volvo, PACCAR, Detroit, Cummins - and never measured torque.
Torque sensors are used in vehicles and aircraft. They are used on engines, gearboxes, crankshafts and transmissions to measure the amount of torque being generated.
