摘要： A method of operating a two-cycle internal combustion engine under low load conditions. A throttle is placed at the intake air system to reduce air intake into the engine cylinders. A pump is placed in the exhaust system, such that it creates reduced pressure downstream of the exhaust valves. In this manner, when the air intake ports close, the exhaust is evacuated and the air trapped in the cylinder is reduced. This permits fuel to be reduced so that the engine may operate in a low load state without losing combustion.

摘要： A method of stoichiometrically operating an internal combustion engine. The engine is equipped with a pre-engine catalyst, which produces syngas from natural gas and air. The engine receives the syngas, as well as natural gas, and recirculated exhaust gas. The amount of syngas and the amount of recirculated exhaust gas are maximized for a desired engine efficiency and NO.sub.x emissions level.
