Abstract

Abstract An internal combustion engine includes: a combustion chamber with a suction opening; an inlet valve for closing the suction opening; a fluid supply line with an open end; and a gaseous medium supply line with an open end. The open end of the fluid supply line is in close proximity to the suction opening. The gaseous medium supply line surrounds a portion of the fluid supply line in the vicinity of the open end of the fluid supply line. The open end of the gaseous medium supply line is in close proximity to the open end of the fluid supply line. And the open end of the gaseous medium supply line is directed toward the suction opening of the combustion chamber. In operation, fluid is supplied through the fluid supply line in such small quantities that the fluid is in an almost pressure-free condition at the open end of the fluid supply line. The fluid is atomized by supplying a gaseous medium through the gaseous medium supply line and past the open end of the fluid supply line at a pressure which is different than the pressure prevailing outside of the open end of the gaseous medium supply line.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 206 words
An internal combustion engine, comprising: a combustion chamber with a suction opening; an inlet valve for closing the suction opening; a fluid supply line with an open end, the open end of the fluid supply line being in close proximity to the suction opening of the combustion chamber; a gaseous medium supply line with an open end, the gaseous medium supply line surrounding a portion of the fluid supply line in the vicinity of the open end of the fluid supply line, the open end of the gaseous medium supply line being in close proximity to the open end of the fluid supply line, the open end of the gaseous medium supply line being directed toward the suction opening of the combustion chamber; means for supplying a fluid through the fluid supply line in such small quantities that the fluid is in an almost pressure-free condition at the open end of the fluid supply line; and gaseous medium supplying means for atomizing the fluid by supplying a gaseous medium through the gaseous medium supply line and past the open end of the fluid supply line at a pressure which is different than the pressure prevailing outside of the open end of the gaseous medium supply line.
Claim 2
Dependent Claim 206 words
An internal combustion engine, comprising: a combustion chamber with a suction opening; an inlet valve for closing the suction opening; a fluid supply line with an open end, the open end of the fluid supply line being in close proximity to the suction opening of the combustion chamber; a gaseous medium supply line with an open end, the gaseous medium supply line surrounding a portion of the fluid supply line in the vicinity of the open end of the fluid supply line, the open end of the gaseous medium supply line being in close proximity to the open end of the fluid supply line, the open end of the gaseous medium supply line being directed toward the suction opening of the combustion chamber; means for supplying a fluid through the fluid supply line in such small quantities that the fluid is in an almost pressure-free condition at the open end of the fluid supply line; and gaseous medium supplying means for atomizing the fluid by supplying a gaseous medium through the gaseous medium supply line and past the open end of the fluid supply line at a pressure which is different than the pressure prevailing outside of the open end of the gaseous medium supply line.
Claim 3
Dependent Claim 23 words
The engine of claim 1, wherein the gaseous medium supplying means includes means for communicating the gaseous medium supply line with atmospheric air.
Claim 4
Dependent Claim 27 words
The engine of claim 1, wherein the gaseous medium supplying means includes an engine exhaust port, the gaseous medium supply line being connected to the exhaust port.
Claim 5
Dependent Claim 24 words
The engine of claim 1, wherein the gaseous medium supplying means includes a compressor, the gaseous medium supply line being connected to the compressor.
Claim 6
Dependent Claim 26 words
The engine of claim 1, wherein the open end of the gaseous medium supply line is smaller than the open end of the fluid supply line.
Claim 7
Dependent Claim 27 words
The engine of claim 1, wherein the open end of the fluid supply line is axially offset from the open end of the gaseous medium supply line.
Claim 8
Dependent Claim 66 words
The engine of claim 1, further comprising a second fluid supply line with an open end, the gaseous medium supply line surrounding a portion of the second fluid supply line in the vicinity of the open end of the second fluid supply line, the open end of the gaseous medium supply line being in close proximity to the open end of the second fluid supply line.
