A New Source of Lightweight, Compact Multifuel Power for Vehicular, Light Aircraft and Auxiliary Applications: The Joint Deere Score™ Engines

Deere & Co. has actively pursued development of the multifuel Wankel-type stratified charge engine since February 1984. During this period, a new R&D facility has been established where development is in progress for three new engine families having basic displacements of .66, 1.72 and 5.8 liters/rotor, for a 1 to 8 rotor engine output range from 37 to 2250kW (50 to 3000HP). The initial SCORE™ (“Stratified Charge Omniverous Rotary Engines”) production engines will be placed into service next year. This series of three engine families offers the size, weight and low vibration characteristics of small gas turbines and the fuel efficiency and initial cost characteristics of diesel engines.This paper describes the combustion concept, relates relevant history and gives the current development status for all three basic sizes.Copyright
