COMPRESSION IGNITION ENGINE OPERATION METHOD AND SYSTEM

摘要

FIELD: engines and pumps.SUBSTANCE: invention can be used in internal combustion engines. The method of operation of the compression ignition engine fuelled by ether-containing fuel obtained from alcohol-based primary fuel is offered which comprises the following stages: 1 - continuous consumption of primary fuel from the fuel tank (2) and compression of fuel in a liquid state up to the final injection pressure; 2 - continuous injection of the compressed primary fuel into the fuel plenum chamber (6); 3 - continuous distribution of the compressed primary fuel into the tubes (9a-9d) connecting the plenum chamber (6) with the fuel nozzles (11a-11d) of the engine; 4 - before supply into the fuel nozzles, continuous conversion of the compressed primary fuel into the ether-containing fuel by the contact with the alcohol dehydration catalyst (10a-10d) located in each tube upstream the fuel nozzles; 5 - continuous injection of ether-containing fuel by the pressure of injection in the engine; 6 - continuous consumption of a part of primary fuel from the plenum chamber and recirculating of the consumed primary fuel into the fuel tank. The fuel system for implementation of the named method is also offered.EFFECT: optimisation of the fuel treatment and storage system in vehicles.11 cl, 1 dwg
