I.C. Engine with oscillating shaft is an innovative new internal combustion engine technology claiming high performance, typically minimizing internal resistance. It claims higher efficiency, higher power, lighter weight, least starting effort, fuel saving in idle running, and miniature starting power source. These conditions lead to most essential requirements of an ideal internal combustion engine and special demands that cannot meet with a conventional power generator. This engine is focused on solving the real problem of fuel saving.

This new internal combustion engine generates 1.55 times higher power. The same static pressure arrangement is applicable for a variety of liquid and gaseous fuel. This engine is ideal to install as the power generator for the hybrid vehicles.

The latest development meets with engine manufacturers’ requirement of straight cylinder and piston. Oscillator internal combustion engine mechanism eliminates the problems associated with crank gear, It can claim higher efficiency, higher power, lighter weight, least starting effort, fuel saving in idle running, and miniature starting power source. These are the most essential requirements of an ideal internal combustion engine and special demands that cannot met with a conventional power generator. This arrangement is applicable as four stroke engine and two stoke engine as well.

A typical construction of this internal combustion engine development consist two banks of cylinders arranged side by side. The pistons are connected with straight piston rods, having a pin on its' stem to engage inside a groove provided at mechanical linkage. The mechanical linkage is a rigid rod in which the central point is fixed to oscillating shaft. The drive force of the piston is transmitted from piston rod to oscillating shaft through mechanical linkage.

IC Engine with Oscillating shaft incorporates an oscillations generator and an oscillations converter coupled by the Oscillating shaft.

This engine is having is straight cylinders or semicircular chambers as working vessel internal combustion engine Straight cylinder version

It is found in operation the amplitude of these oscillations should be controlled to get the required performance. Therefore the pinion, fitted at the end of oscillating shaft is engaging with a rack of gears attached to a connecting rod. The connecting rod is coupled to a freely driven crank gear, permitting the pinion and the shaft to oscillate within defined amplitude.
