Single-cylinder testing of an Electronic Pilot Fuel Injection (EPFI) system indicated that a 45 percent reduction in NO{sub x} emissions could be obtained with a 3 percent improvement in fuel consumption by replacing the mechanical system, delivering 6 percent pilot, with the EPFI at 2.9 percent delivery. Further optimization testing of this system at pilot levels down to 0.7 percent over a wide range of timings and air/fuel ratios resulted in even further reductions in NO{sub x} emissions without fuel penalty. The EPFI system can yield NO{sub x} emissions levels significantly below 2 g/BHP-h with an improvement in fuel consumption of at least 3--4 percent, and probably yield emissions level as low as 0.5 g/BHP-h without substantial penalties in efficiency or operability.
