NEGATIVE SUPERCHARGING

[attachment=17012]
INTRODUCTION

WHAT IS MEAN BY SUPERCHARGING ?

IN THE NEGATIVE SUPERCHARGING PROCESS, POSITIVE EXHAUST PRESSURE CONVERTED INTO NEGATIVE BOOST TO PULL MORE AIR INTO THE ENGINE.

OPPOSITE TO CONVENTIONAL SUPERCHARGING.


COMBUSTION STROKE


EXHASUT VALVE OPENS
VELOCITY INCREASES IN TRI-Y HEADER(TWICE)


EXHAUST STROKE

.EXHAUST VALVE CLOSES EARLY.
.REDUCED OVERLAP DURATION
.LESS EXHAUST VALVE LIFT


COMPRESSION STROKE


INTAKE VALVE CLOSES EARLIER TO PREVENT THE AIR FROM BEING FORCED BACK INTO INTAKE MANIFOLD.


APPLICATIONS

.IN ALL CONVENTIONAL VEHICLES (4- STROKE)
.CARS, TRUCKS, BUSES, BOATS, TRACTORS ETC.


CONCLUSION


NEGATIVE SUPERCHARGING IS MORE EFFICICENT PROCESS THAN CONVENTIONAL SUPERCHARGING, WHICH INCREASES THE PEFORMANCE OF AN ENINGE WITH LESS COST AS THE COMPONENTS REQUIRES ARE LESS.
