Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The device is divided into four parts: a. Exhaust gas treatment module: including engine 1, reformer 2, and three-way catalytic converter 3. Wherein the exhaust pipe of the engine 1 is connected to the reformer 2 that recovers the waste heat of the engine exhaust, and the reformer 2 is connected to the three-way catalytic converter 3 that processes the engine exhaust; b. reforming fuel supply module: including reforming fuel tank 6, Reforming fuel pump 7 , reforming fuel nozzle 8 . The reformed fuel pump 7 is connected to the reformed fuel tank 6 to pump fuel out, and the reformed fuel nozzle 8 that injects fuel into the reformer 2 is connected to the reformed fuel pump 7; c. reformed gas storage and supply module : Including a reformed gas pump 9 , a reformed gas storage tank 10 , an intake pipe nozzle 11 and an exhaust pipe nozzle 12 . Among ...

Abstract

The invention relates to an engine combustion optimization and exhaust purification device and method based on reformed gases, in particular to the fields of recycling and utilization of waste heat in engine exhaust, hydrogen production technology based on fuel reforming, mixed combustion of reformed gases of an engine, exhaust treatment and the like. The device is divided into four parts: a, an exhaust treatment module; b, a reformed fuel supply module; c, a reformed gas storage and supply module; and d, an electronic control module; and the reformed gases including H2 and CO can be preparedvia reforming reaction of reforming fuels in the presence of a catalyst and at a certain temperature. The reformed gases and gasoline can be filled into an engine cylinder for mixed combustion. The composition of fuels of an internal combustion engine can be improved in an early period, the combustion in the cylinder can be optimized, the engine exhaust can be treated in a late period, and the purpose of exhaust purification can be achieved.

Description

technical field [0001] The invention provides a device and method for engine combustion optimization and exhaust purification based on reformed gas, which mainly uses automobile exhaust to provide a heat source for a reforming reactor, and the reforming fuel undergoes a reforming reaction under a catalyst and a certain temperature condition Production of reformed gas. The reformed gas can not only be mixed with fuel and burned in the engine cylinder, but also can react with NOx in the exhaust gas, so as to achieve the purpose of exhaust purification. Engine mixed reforming gas combustion and exhaust gas treatment and other related fields. Background technique [0002] The continuous consumption of fossil fuels and environmental pollution have aroused widespread concern in the society as problems restricting my country's economic development. At the same time, with the continuous development and growth of the automobile industry, the number of automobiles in my country has b...
