INPULSE is an anti-detonant injection (ADI) system controlled by sensors that actively monitor manifold pressure and cylinder head temperatures. The water-methanol injection nozzles, located in the intake manifold, are activated when when the manifold pressure is above 25 inches of mercury or the cylinder head temperature is above 400°F. During cruise flight conditions the system is turned off maximizing savings.
INPULSE is a simple technology that allows operators to safely use unleaded fuel in high-compression engines.
ADI uses a mixture of 60% methanol, 39% demineralized water and 1% soluble oil.
