REDUCER-EVAPORATOR FOR LIQUEFIED HYDROCARBON GAS Russian patent published in 2014 - IPC F02M21/06 F02M31/16 

FIELD: engines and pumps.

SUBSTANCE: source of heat for a gas reducer is made in the form of a p-channel fixed to the outer surface of the first MOSFET-transistor reducer evaporator cavity, and this p-channel is within the composition of the evaporator cavity body electronic heater circuit. The full circuit of the electronic heater comprises the second transistor of n-p-n type, the third MOSFET-transistor of the p-channel, two operational amplifiers, nine resistors and a fuse.

EFFECT: simplified design of an evaporator reducer due to elimination of liquid cooling, its assembly, guaranteed start-up of a cold ICE on gas fuel under negative temperatures, increased accuracy of gas temperature maintenance at the inlet to ICE and increased speed of correction of gas temperature by reducer-evaporator at sharp changes of ICE operation modes.
