ABSTRACT:
A two-cycle crankcase compression diesel engine having a scavenge control system for controlling the amount of scavenging flow and an exhaust control system for controlling the effective compression ratio and the effective flow area of the exhaust system. These controls are operated during normal engine running conditions at most speed ranges from a three dimensional map. However, special control routines and valve operating arrangements are provided for pre-starting, starting, idle, engine braking or deceleration and rapid acceleration so as to improve the running under these transient or non-normal conditions.
