AUTOMOTIVE FUEL SYSTEM DEVICE DRIVEN BY INTERNAL COMBUSTION ENGINE Russian patent published in 2011 - IPC F02D41/00 F02D43/00 F02D19/08 G01M15/10 

FIELD: engines and pumps.

SUBSTANCE: proposed device comprises control unit connected to feed pipeline between duel tank and ICE, fuel consumption metre, data accumulator, fuel sampler and fuel analyser. Fuel analyser allows continuous analysis. Additionally, said analyser incorporates a number of fuel parametres, and/or assemblage of data on emission quota related to climatic and/or geographic conditions. Assemblage of data on emission quota comprises the data on one or larger amount of gases CO₂, NO_x, and CO, as well as emission of solid particles. Proposed method of controlling fuel feed into ICE comprises the following stages: connecting control unit to feed pipeline between fuel tank and ICE; recording current fuel consumption at any time interval; determining fuel characteristics related with combustion products emission by continuous or periodical analysis; comparing current emission of combustion products with tolerances. In case the latter are exceeded, correcting fuel feed into ICE. Said correction comprises limiting or terminating fuel feed, adjusting ICE power output, limiting ICE running time and/or running distance.

EFFECT: higher accuracy of analysis.
