Abstract
An innovative connecting rod and drive shaft mechanism has been proposed which will serve to improve the Diesel Engine efficiency by significantly reducing the frictional losses. The new mechanism will have a reduced connecting rod oscillation angle; thereby reducing cylinder rubbing forces. Mechanical efficiency is also high as it employs a favorable transmission angle between the connecting rod and drive shaft gears. Theoretical calculations show that about 10% fuel economy is achievable by adopting this New Concept, which extracts maximum energy from combustion gasses. This mechanism generates Trapezoidal Piston Velocity Profile instead of Sinusoidal one which is in current usage. This concept is not yet tried anywhere so far.
