Blow-by Control T-REV

This device changes the pressure inside the engine crankcase from positive to negative.
The negative pressure reduces the force pushing the pistons back due to pressure and reduces air resistance, making it easier for the pistons to move.
To prevent the negative pressure from exceeding the specified limit, the α system’s valve control draws in atmospheric air from the air filter to regulate the pressure .

The benefits are:
Improved engine pickup.
Better response when pressing the accelerator pedal from a standstill.
Smoother gear shifts.
