Methanol recombination device started by waste heat of engine

Abstract

The invention relates to a methanol recombination device started by waste heat of an engine. The methanol recombination device can absorb the waste heat of the engine rapidly to prepare hydrogen; and the prepared hydrogen can be sent to the engine for combustion, so as to achieve an object of reducing pollution and saving oil. The methanol recombination device comprises a heat receiver, a heat conductor and a catalyst bed, wherein the heat receiver has perforations one-to-one correspondingly to discharge outlets of the waste gas of the engine, the heat receiver can be disposed between the engine and an exhaust pipe to make one end surface of the heat receiver applied to the engine and the opposite end surface of the heat receiver connected with the exhaust pipe, each perforation of the heat receiver aligns to the discharge outlet of the waste gas of the engine, so that the heat in the waste gas and the heat of the engine can be absorbed; and the heat conductor is connected with the heat receiver, so that the heat of the heat receiver can be absorbed; the catalyst bed is connected with the heat conductor, so that the heat of the heat conductor can be absorbed to be used as heat source needed by performing a chemical reaction on a methanol water solution, so as to produce hydrogen.

Description

technical field [0001] The invention relates to a methanol recombiner that uses engine waste heat to start, which can mainly improve the efficiency of absorbing engine waste heat, shorten the time required for starting the methanol recombiner, and send hydrogen into the engine to make the fuel in the engine burn completely. , to achieve the purpose of saving fuel and reducing pollution. Background technique [0002] Since the use of vehicles is not only an important source of greenhouse gas emissions, but also a sector that is highly dependent on petroleum, energy conservation and carbon reduction for vehicles is an important policy direction. [0003] In order to achieve good ignition and combustion efficiency for general vehicle internal combustion engines, the car factory internally sets its optimum air-fuel ratio A value (the mixing ratio of air and fuel, usually 14.5-15.0). To maximize the combustion efficiency. When producing fuel-efficient vehicles, world-renowned a...

[0009] 2) The electricity required for water electrolysis (4-5 degrees per cubic meter of hydrogen) comes indirectly from the fuel produced by the operation of the engine. If the amount of hydrogen is high, it will cause waste of fuel and offset the benefits of hydrogen combustion. If the amount of hydrogen injected is low , the benefit will not be obvious

The Hydrogen-Boosted GasolineEngine, developed by researchers at the Massachusetts Institute of Technology and improved by ArvinMeritor and IAV, a German automotive engineering company, relies on the on-board hydrogen production equipment to add 15-30% hydrogen to the existing car engine to achieve Improve energy efficiency by 30% to reduce fuel costs, and because of the help of hydrogen, the fuel can be burned more completely, reducing exhaust emissions, and more effectively reducing NOx emissions to almost nothing. The equipment for this method is complex, expensive, and its hydrogen concentration is very high Low, about 12-18%, limited benefit

As a result, there is so far a lack of commercial products
