Primary purpose of an IC Engine is to give TORQUE. All IC Engines produce torque in SINE WAVE. Co sine components of forces acting on piston are wasted as heat, noise & vibrations. This is so right since IC Engine invention. No one else has so far EVEN POINTED IT OUT. I have done extensive research on this aspect & have invented TEJJ Constant Torque IC Engine which eliminates all co sine component losses. It is Patent pending in India.
