US 2013/0340502 A1 · FUEL PHYSICAL PROPERTY DETERMINATION METHOD AND FUEL PHYSICAL PROPERTY DETERMINATION DEVICE

Abstract

The fuel physical property determination method relating to the first aspect of the present invention includes: a test fuel flame-imaging step of obtaining imaging data by imaging flames formed by supplying a pre-mixed gas containing a test fuel and an oxidant agent, to a test tube in which an internal flow path thereof has a diameter set smaller than a flame-quenching distance at normal temperature; and a physical property determination step of determining a physical property of the test fuel by comparing the imaging data obtained in the test fuel flame-imaging step and imaging data obtained by imaging flames ignited by supplying a pre-mixed gas containing a standard-mixed fuel and an oxidant agent, to the test tube, the standard-mixed fuel having a known physical property.

A fuel physical property determination method to determine a physical property of a test fuel, the method comprising:

a test fuel flame-imaging step of obtaining imaging data by imaging flames formed by supplying a pre-mixed gas containing the test fuel and an oxidant agent, to a test tube which includes an internal flow path and in which a temperature distribution is formed;
and
a physical property determination step of determining the physical property of the test fuel by comparing the imaging data obtained in the test fuel flame-imaging step and imaging data obtained by imaging flames ignited by supplying a pro-mixed gas containing a standard-mixed fuel and an oxidant agent, to the test tube, the standard-mixed fuel having a known physical property.

A fuel physical property determination device to determine a physical property of a test fuel, the device comprising:

a test tube including an internal flow path;
a temperature distribution-forming device to form a temperature distribution in the test tube;
a supply device to supply a first pre-mixed gas containing the test fuel and an oxidant agent, to the test tube;
an imaging device to obtain first-imaging data by imaging flames formed by supplying the first pre-mixed gas to the test tube;
a processing storage device to determine the physical property of the test fuel by comparing the first-imaging data obtained by the imaging device and second-imaging data obtained by imaging flames formed by supplying a second pro-mixed gas containing a standard-mixed fuel and an oxidant agent, to the test tube, the standard-mixed fuel having a known physical property.
