ROUSH CleanTech began production of its Gen 5 propane autogas fuel system in Sept. 2020. The company’s innovative propane autogas technology integrates Ford’s new 7.3L V8 engine in Class 3-7 chassis.
Ford’s new 7.3L engine is compact, durable, and easy to maintain. It is narrower than the previous 6.8L, allowing it to fit into multiple vehicle chassis and be serviced with similar automotive parts across each chassis. Innovations for the Gen 5 propane fuel system include stronger and lighter forged fuel rails and a support bracket that keeps the engine fuel distribution well organized.
The engine is designed to meet current and future emissions requirements. ROUSH CleanTech’s Gen 5 is certified to California Air Resources Board’s optional low nitrogen oxide emissions standard of 0.05 grams per brake horsepower-hour (g/bhp-hr). The Gen 5 system reduces greenhouse gas emissions, which helps optimize fuel efficiency, and can operate on renewable propane, which further reduces emissions and carbon intensity values.
