...From numerous engineering innovations (direct injection petrol engines, engine balance shafts, Super-All Wheel Control...) to endless demonstrations of ability & reliability through racing at the highest level with Pajero and Lancer Evolution;
WGP has historically determined that the peak-firing pressure (PFP) method provides the best measure of engine balance. There are two basic requirements for proper peak-firing pressure balance: accurate peak-firing pressure and control of fuel delivery system to each cylinder.
Since accurate peak-firing pressure available from the Windrock continuous pressure monitoring system would satisfy the first requirement of this method of engine balance, the two companies agreed to participate in a developmental project which involved power cylinder autobalancing of a legacy two-cycle engine.
* Refinement was a centerpiece of the Sentra's design, as shown by the cradle type engine subframe, liquid-filled engine mounts, engine balance shaft, and equal-length intake runners.
