The T-REVmini cannot be seen when normally installed, but it can be seen from the side, improving customization and maintainability! *Note* This is exclusively for the T-REVmini. This installation method is not possible with STD T-REV. We call a part with this structure a "blow-by gas management valve", which reduces rotational friction by reducing the pressure inside the crankcase. The structure and installation are very simple, just insert the "T-REV" into the blow-by line! The structure is a one-way valve that prevents the backflow of outside air and utilizes the pulsation of the vertical movement of the piston to create negative pressure inside the crankcase, similar to a "vacuum pump", thereby reducing piston resistance and stirring resistance (during crank rotation). Stirring This results in less engine braking, less engine vibration, and an engine feeling that feels like it has been highly tuned to remove internal engine friction. Naturally, this also leads to improved fuel efficiency. So why is this effect achieved?Reciprocating engines involve a reciprocating slider movement of the piston, so in a single cylinder engine, for example, when the piston is at its highest position and when it is at its lowest position, the volume inside the crankcase increases or decreases by the amount of displacement. It will be. In addition, in reciprocating engines, blow-by gas flows in from the gap between the piston and cylinder, so modern engines are always equipped with a blow-by line as standard to release these volume changes. The air inside the crankcase is moved in conjunction with the up and down movement of the piston. In other words, air is discharged from the blow-by line when the piston descends, and air is sucked in from the blow-by line when the piston rises, creating a pulsating phenomenon at the tip of the blow-by line while the engine is running. T-REV interrupts the blow-by line where this pulsation occurs to prevent backflow of air when the piston rises and change to a negative pressure state. Negative pressure means that the air density remaining inside the crankcase is reduced. Lowering the air density in the crankcase reduces the weight of air that moves violently within the crankcase during engine operation, and reduces the air agitation resistance that occurs as the engine rotates. In other words, lowering the internal pressure of the crankcase = lowering the air density inside the crankcase = the weight of the air is lighter, making it easier to move = reducing the resistance when the engine rotates.
