Abstract
A two-cycle diesel engine and means for operating it to improve the performance by increasing the compression ratio by the closing of a supplemental exhaust port under light loads and low speeds. In order to reduce combustion chamber temperature and reduce nitrous oxide emissions, the injection timing is advanced an additional increment during the closing of the supplemental exhaust port. Various control strategies are described which involve either quickly raising the compression ratio and retarding the injection timing.
