ROTARY INTERNAL COMBUSTION ENGINE

摘要

The present invention comprises a novel rotary internal combustion engine comprising Primary object of the present invention is to provide an internal combustion engine which is free of the shortcoming of the existing reciprocating IC engine by its unique feature of rotary motion to minimize wear, tear vibration and noise, free of unbalance and stresses incurred in reciprocating IC engine. Providing axially moving vanes instead of radial vanes to minimize the effect of centrifugal force particularly under high speed operation by further providing novel mechanism to nullify centrifugal forces acting there upon to minimizing excessive friction, rubbing, warping, bending of vanes. It is having sinusoidal profile of housing grooves so that axial vanes movement is in simple harmonic motion which is scientifically most desirable and further the volume displacement in charge cavity varying sinusoidally. It provides plurality of vanes forming multiple of charge cavities thus providing multiple thermodynamic cycles per rotation thus increasing the power of the said engine many fold thus increasing the power to weight ratio many times. It provides double acting vanes to operate in both the housings thereby doubling the output of the said engine and further balancing the axial forces due to fuel ignition means power stroke forces on the housings and rotor. It provides, inlet and exhaust port and dispenses with complex inlet valve, exhaust valves and associated valve operating mechanism. It provides direct transmission of the generated torque to the shaft. It has grooves in the housings on either sides of the rotating part to counter combustion forces or pressure thereby minimizing stresses. It works equally efficiently with SI as well as CI system. It provides simple arrangement for cooling and lubricating arrangement with ease for providing inbuilt lubricating pump without change in the basic construction of the engine. It provides high power to weight ratio, reliable, efficient, low in maintenance, requiring minimum number components and is easy to manufacture.
