Abstract

Official abstract text for this publication.

A fuel supply system for an internal combustion engine includes a heat exchanger that has a heat exchanging wall between a liquefied fuel passage and an engine coolant passage. Heated and vaporized fuel flowing out from the liquefied fuel passage of the heat exchanger is supplied to the internal combustion engine. A flow rate of liquefied fuel supplied to the liquefied fuel passage of the heat exchanger is set. A flow rate of engine coolant supplied to the engine coolant passage of the heat exchanger is determined on the basis of a temperature of the engine coolant supplied to the engine coolant passage of the heat exchanger such that nucleate boiling or transition boiling of the liquefied fuel in the set flow rate occurs near a boundary between nucleate boiling and transition boiling in the liquefied fuel passage.

First claim

Opening claim text (preview).

The invention claimed is: 1. A fuel supply method for an internal combustion engine, which supplies heated and vaporized fuel to the internal combustion engine, comprising: providing a heat exchanger that has a heat exchanging wall between a liquefied fuel passage and an engine coolant passage, wherein the heated and vaporized fuel flows out from the liquefied fuel passage of the heat exchanger; setting a flow rate of liquefied fuel supplied to the liquefied fuel passage of the heat exchanger, and determining a flow rate of engine coolant supplied to the engine coolant passage of the heat exchanger on the basis of a temperature of the engine coolant supplied to the engine coolant passage of the heat exchanger such that nucleate boiling or transition boiling of the liquefied fuel in a set flow rate occurs near a boundary between nucleate boiling and transition boiling in the liquefied fuel passage.
