A Stratified Charge Multifuel Military Engine-A Progress Report

This paper is a progress report on the conversion of the military L-141 gasoline engine to the Texaco Controlled-Combustion System and the evaluation of naturally aspirated and turbocharged installations in an M-151 vehicle. Relative to the standard gasoline vehicle, significant improvement in fuel economy with low exhaust emission levels were demonstrated as were the multifuel capabilities and excellent cold starting facility of the combustion concept. Possibilities for further improvement in TCCS exhaust quality through adjustment of operating parameters and add-on devices are also presented. This work was done under contract to the U.S. Army Tank-Automotive Command.
