Actually I have 2 questions. 1-) How do we calculate the torque that the engine generates? t=F.d so F= The force piston exerts on crank arm. and d= length of crank arm. Can we calculate like this or is it completely different? 2-)Torque values of a car in the technical information is the torque engine generates or the wheels exerts on ground? or these two are the same? In otherwords, is the torque of the engine directly transfered to the wheels?
