AVCR 1360-2 High Specific Output-Variable Compression Ratio Diesel Engine

This paper addresses the development of the Teledyne Continental Motors' (TCM) AVCR 1360-2 variable compression ratio (VCR) diesel engine. This is the culmination of fifteen years of VCR piston and high specific output research. The unique configuration and resulting performance of this 335 BMEP engine are presented.

The special features of the engine design which were refined during the AVCR 1360-2 development phase are discussed. Those features accentuated are the VCR piston system, the X-pump fuel injection system and the high pressure ratio induction system.

Programs for development of satisfactory steady state and transient performance and the design modifications necessary to reduce the peak transient smoke burst to acceptable levels are described.
