Abstract
Abstract A device for improving combustion efficiency of an internal combustion engine includes an elongated flexible sheet, a flexible metallic reflector attached to the flexible sheet for reflecting the extreme infra-red radiation, a ceramic radiation source attached to the reflector and a fastener for attaching the flexible sheet to an air intake duct of the engine with the radiation source facing toward the duct. The extreme infra-red radiation having a wavelength of from 8 μm to 10 μm irradiates the air incoming through the duct before combustion within the engine combustion chamber, whereby the combustion efficiency of the internal combustion engine is improved.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
A process for improving combustion efficiency of a combustion machine having a duct for introducing air into a combustion chamber, comprising the steps of: preparing a source of extreme infra-red radiation having a wavelength of from 8 μm to 10 μm; and placing said source of extreme infra-red radiation in the vicinity of said duct so that the air incoming through said duct is irradiated by said extreme infra-red radiation before combustion within the combustion chamber whereby the combustion efficiency of the combustion engine is improved.
Claim 2
Dependent Claim
86 words
A process for improving combustion efficiency of a combustion machine having a duct for introducing air into a combustion chamber, comprising the steps of: preparing a source of extreme infra-red radiation having a wavelength of from 8 μm to 10 μm; and placing said source of extreme infra-red radiation in the vicinity of said duct so that the air incoming through said duct is irradiated by said extreme infra-red radiation before combustion within the combustion chamber whereby the combustion efficiency of the combustion engine is improved.
Claim 3
Independent Claim
84 words
A device for improving combustion efficiency of a combustion machine having a duct for introducing air into a combustion chamber, comprising: a source of extreme infra-red radiation having a wavelength of from 8 μm to 10 μm; and means for attaching said source of extreme infra-red radiation in the vicinity of said duct so that the air incoming through said duct is irradiated by said extreme infrared radiation before combustion within the combustion chamber whereby the combustion efficiency of the combustion engine is improved.
Claim 4
Independent Claim
84 words
A device for improving combustion efficiency of a combustion machine having a duct for introducing air into a combustion chamber, comprising: a source of extreme infra-red radiation having a wavelength of from 8 μm to 10 μm; and means for attaching said source of extreme infra-red radiation in the vicinity of said duct so that the air incoming through said duct is irradiated by said extreme infrared radiation before combustion within the combustion chamber whereby the combustion efficiency of the combustion engine is improved.
