The Digest’s 2025 Multi-Slide Guide to High Pressure DI for Propane-DME Light-Duty Engines

Technological advances include a 1500-bar High Pressure Fuel Pump (HPFP) with 50% efficiency gain and high-flow injectors reducing hydraulic delay by over 50%. Partners are WM International Engineering (PI), IIT, ANL, and Diversified CPC International. All BP2 milestones were met, including successful 200-hour durability testing, system integration onto a Hyundai engine, and attaining the interim CO2 emission target of 150 gCO2/km.
