Hi. Torque is a force, the tendency of rotation of an object or element, is applied daily in our actions, when turning a key, opening a door, turning a tool at work. An engine will have more force in relation to its maximum torque. To measure a dynamometric bench is used, of course in this sense there are differences from a gasoline to a diesel. The power is the speed at which the engine can be driven, being the maximum of the first in relation to the torque obtained on the generated rotation speed. Cv, power, torque, speed, fuel economy and cash relations, complex formulas in search of a very difficult balance to establish, some of them will have to be set aside if you are looking for more performance in an engine, including the fuel consumption. Salu2.
