APPLICATION OF HELMHOLTZ CONCEPT ON FOUR STROKES THREE CYLINDER ENGINE

This Paper aims on problem of to the lower torque of the engines at low engine speeds. To prevent engine stall the vehicle needs to be revved high. This increases the running cost of the vehicle. The main objective of the paper is to reduce the fuel consumption of engine by increasing the torque at low engine speeds by achieving a ram air effect. Helmholtzresonance chamber uses the concept of Helmholtz resonance to achieve a ram effect in the intake manifold this effect causes a return of air fuel charge into the manifold at lower engine speeds thereby achieving a higher volumetric efficiency.
