An Investigation of the Addition of Hydrogen to Methanol on the Operation of an Unthrottled Otto Engine

Previous investigations concerning the addition of hydrogen to the air-gasoline mixture have shown the advantages of this operation in the OTTO- ENGINE. Due to the lean flammability limits of hydrogen and the chemical quality of methanol in reference to gasoline higher efficiencies and a reduction in exhaust emissions could be demonstrated.

Another advantage is that these fuels -hydrogen and methanol- are not be based on petrol and can be produced synthetically.

Furthermore the positive influence of addition of hydrogen on such parameters as burning velocity, combustion duration, burned fraction etc. can be demonstrated.
