TVAATAKTS FOERBRAENNINGSMOTOR MED OEVERLADDNINGSAGGREGAT

摘要

The invention relates to a more complex but considerably more emission-poor two-stroke engine than the conventional one. The HC-emissions become zero when completely burned. CO is controlled by the mixture ratio and NOx becomes very low owing to the built-in EGR. A super charger (20) presses air through the cylinder after the power stroke and dilutes the exhaust gases. A carburettor unit (21) is fed by the super charger and presses an overrich gas mixture into the cylinder at the beginning of the compression stroke. A slide gate (22) controls the connection between the carburettor unit and the cylinder.
