Team Orion have shown this unique and rather innovative constant pressure device (CPD) on their stand at this weeks show in Germany. Created to solve engine tuning problems that arise when you switch from full throttle to low speed, high pressure generated from running at full throttle is still present and it is pushing fuel to the carburettor inlet even though the carburettor is closed. Because of this the mixture will become too rich, causing slower acceleration and wasting fuel. This device solves that.
The CRF CPD acting as a pressure valve system, effectively resolves this problem by regulating the amount of pressure going to the fuel tank. The valve allows a constant amount of pressure to be sent to the fuel tank, by opening or closing itself depending on the engine’s rotation speed.
The eagled eyed amongst you would have noticed this device on Adrien Bertins Kyosho from our photos yesterday.
