UPS MULTIFUEL STRATIFIED CHARGE ENGINE DEVELOPMENT--PROGRESS REPORT

Initial development of the United Parcel Service stratified charge engine (UPS 292 SC) began in 1978, and by the fall of 1980 the first full track test of the engine was completed with an installation in a UPS delivery van. The engine now is in production for the purpose of a 500-vehicle, nationwide test of the engine under actual package delivery operating conditions. Vehicles powered by the UPS 292 SC will be based for test purposes in locations offering varied conditions of temperature and terrain to determine whether any defects in design or components remain to be corrected. At present some 125 of the engines are being run in UPS operations, and some 175 of the engines are in transit or awaiting installation around the country. An engine development program is an unusual venture for a transportation company that lacks experienced personnel facilities for such a project. This report will note, particularly, the exceptional cooperation of American automotive component suppliers, without whose contributions this work could not have been completed. This report will trace the genesis of the engine and focus in detail on the engineering problems encountered and the solutions that evolved. In addition to engineering detail, a cursory assessment of the engine in the context of national petroleum supplies will be offered as well as some insights into potential improvements that may add to the value of this promising development.
