TRIFECTA's Active Rail Pressure Management   Introduction – Direct Injection   Over the last 10 years, General Motors (GM) has been converting all of their engines to use what they call SIDI (Spark Ignited Direct Injection), oft referred to as just DI (Direct Injection). DI promises improved fuel economy, improved engine power and lower vehicle emissions versus the traditional MPFI (Multi Point Fuel Injection) that has been in use since the late 1980s on General Motors vehicles.   However, DI eq

TRIFECTA: Active Rail Pressure Management

 

TRIFECTA has taken an innovative approach to dealing with potential fuel system capacity constraints. We recognize that the majority of people wishing to turn the boost (and, hence, power) up on their turbocharged DI engines wish also to have non-invasive and reversible modifications to their vehicles. As such, we have developed a software-based solution which resides in the ECM, as part of some of our recalibration products, which actively and dynamically manages the fuel demand vs the fuel system capacity.
