BASIC CONCEPT
The conventional 4 cycle engine repeats the 1) intake stroke, 2) compression
stroke,3) power stroke, and 4) exhaust stroke thousands times in a minute to
produce power.
When the piston is pushed down from the dead center in the power stroke, small blow-by gas goes to the crank case through the piston rings, which produces a positive pressure and causes a drag to the piston movement.
The blow-by gas is extracted through the breather pipe but the positive pressure in the crank case tends to remain with the air back-fowed when the piston moves upward or when the throttle is closed (acceleration is off).
The T-REV® SYSTEM, by controlling this back flow in the breather system, optimizes the pressure in the crank case and creates the ultra-smooth piston movement.
