United Parcel Service Applies Texaco Stratified Charge Engine Technology to Power Parcel Delivery Vans-Progress Report

The UPS 292 SC program to apply the Texaco Controlled-Combustion System (TCCS) to package delivery van service was initiated in April 1978. This included engine evaluations to determine conversion feasibility. The GM 292 in³ six cylinder gasoline engine was found to be as compatible with the TCCS. Design of the conversion was accomplished by Ricardo Consulting Engineers Ltd., while performance confirmation on a laboratory single cylinder engine was carried out in Texaco's Beacon Research Laboratories.

Four multi-cylinder engines were fabricated by Ricardo. One has been dynamometer tested and installed in a UPS Package Delivery Van. Performance comparison with a standard GM 292 will be presented. The test program has included side-by-side vehicle operation in simulated parcel delivery service. Future plans will be discussed.
