ABSTRACT:
An exhaust control system for a two-cycle, crankcase compression, direct injection engine wherein an exhaust control valve modifies the effective cross-sectional area of the exhaust system in response to engine speed and operator demand to provide optimum charging and scavenging conditions. The exhaust control system is modified in response to other than normal steady state operating conditions such as during starting, warm up, and during rapid changes in engine speed and/or load and/or operator demand so as to improve performance during these conditions.
