Development of natural gas rotary engines. Final report, June 1986-June 1991
Development of natural gas-fueled rotary engines was pursued on the parallel paths of converted Mazda automotive engines and of establishing technology and demonstration of a test model of a larger John Deere Technologies rotary engine with power capability of 250 HP per power section for future production of multi-rotor engines with power ratings of 250, 500, 1000 HP and upward. Mazda engines were converted to natural gas and were characterized by laboratory test which was followed by nearly 12,000 hours of testing in three different field installations. To develop technology for the larger JDTI engine, laboratory and engine materials testing was accomplished. Extensive combustion analysis computer codes were modified, verified, and utilized to predict engine performance, to guide parameters for actual engine design, and to identify further improvements. A single rotor test engine of 5.8 liter displacement was designed for natural gas operation based on the JDTI 580 engine series. This engine was built and tested. It ran well and essentially achieved predicted performance. Lean combustion and low NOX emission were demonstrated.
