IC engine uses hydrogen generated electrolytically in operating space - to increase efficiency and reduce waste and emission

摘要

In driving an engine by combustion of H2, the novelty is that the H2 and O2 for combustion are produced in the operating space of the engine of electrolytic dissociation of water. Pref. dissociation is accelerated by adding an alkali cpd.. The engine is a piston engine and the electrolyser is placed in the walls of the combustion chamber. In particular, an 8-stroke engine is used. At the start of the stroke, water, opt. with catalyst, is sucked in or injected. Strokes 2,4 and 6 comprise compression, strokes 3, 5 and 7 expansion to convert the combustion to mechanical work and stroke 8 exhaustion of the combustion gases. Electrolysis starts immediately after intake or injection of water at the start of stroke 1 and continues up to the start of stroke 7. Combustion may be triggered by external ignition or autoignition. USE/ADVANTAGE - The technique reduces waste and is efficient since it eliminates the need to remove the combustion prods. after each combustion, which wastes hot and partly oxidised prods.. It can be used in 2- or 4-stroke or rotary engines or even cycles with more than one working stroke, e.g. an 8-stroke cycle with 3 working strokes or a 16-stroke cycle with 7 working strokes. Emissions are very slight, with only small amts. of NOx. CO and CO2 are emitted only to the extent that they are present in the air used for combustion.
