Torque is the twisting force that causes rotation. To have this youll need either torque sensors on the crankshaft or pressure sensors in the engine cylinder(s). torque = (350 5,252) 5,000 torque = 1,838,200 5,000 torque = 367.64 ft-lb, Convert lb/hr to cc/min & cc/min to lb/hr. As an example, if a gasoline engine has 350 horsepower, the torque of an engine will be 367, as multiply multiply by 5,252 (between foot-pounds and horsepower), divided by the speed of the engine. One of the main instruments or devices that are used in measuring torque is given below. For example, if an engine develops 1,000 pound-feet of torque at rated power, and 1,400 pound-feet at torque peak, it has a torque rise of 40 per cent. The formula for calculating the power of an engine is as follows:Ne = Vh * Pe * n / 120 (kW), where: Vh engine volume, cm. In the case of a translation of a propelling van, one can consider the measure of drag to measure the force. The torque which is available in the engine control system is mapped from dyno tests, it is not instantaneous engine torque.
