Embodiment Construction

[0028] Such as figure 1 As shown, the light hydrocarbon fuel reforming system of the present invention includes a light hydrocarbon fuel supply device, a diesel fuel supply device, a reforming reaction device 6 and a gas mixer 2 . The gas mixer 2 is arranged after the light hydrocarbon fuel supply device, the reforming reaction device 6 is arranged after the gas mixer 2, the diesel fuel supply device is arranged in the diesel engine 15, and the exhaust gas 1 of the diesel engine is discharged into the exhaust gas from the exhaust valve 21. The pipe 9 is heated by the reforming reaction device 6 and discharged into the atmosphere. The temperature of the engine exhaust gas will be different under different working conditions. Therefore, a temperature compensator 30 is installed inside the reforming reaction device 6 to meet the reaction conditions temperature, so that the reforming reaction occurs normally.

Abstract

The invention discloses a light hydrocarbon / diesel fuel reforming system and a reforming method. The reforming system comprises a light hydrocarbon fuel supply device, a diesel supply device, a reforming reaction device and a gas mixer. The gas mixer is provided with a carrier gas inlet pipe and a water vapor gas inlet pipe, the light hydrocarbon fuel supply device is used for supplying atomized light hydrocarbon fuel, and the diesel supply device is used for supplying atomized diesel. The atomized light hydrocarbon fuel and diesel enter the gas mixer through a pipeline to form mixture gas with carrier gas and water vapor, the mixed gas enters the reforming reaction device for reforming reaction, and reforming gas generated in the reforming reaction device is sent into a combustion chamberof an engine gas cylinder to participate in combustion through the pipeline. The reforming reaction device is arranged in a tail gas exhaust pipe of the gas cylinder. According to the light hydrocarbon / diesel fuel reforming system and the reforming method, the reforming reaction device is directly heated by using the high temperature waste heat of engine tail gas as a heat source, the energy is saved, after the reforming of the diesel and light hydrocarbon, the combustion efficiency of the diesel is greatly improved, and engine knocking and the emission of nitrogen oxide are suppressed.

Description

technical field [0001] The invention belongs to the technical field of engines, and relates to a raw material supply technology for engines, in particular to a light hydrocarbon / diesel fuel reforming system and a reforming method. Background technique [0002] Under the dual effects of energy crisis and environmental protection, finding alternative energy sources and reducing pollutant emissions has become a hot topic in the field of internal combustion engine research. Although the economy of a pure diesel engine is much better than that of a gasoline engine, the waste of the diesel engine itself is also very serious. The incomplete combustion of diesel is not only a waste of energy, but also a threat to the environment. For natural gas engines, low temperature lean burn technology is often used to suppress knock and nitrogen oxide (NOx) emissions. However, an air-fuel ratio that is too high can lead to engine misfire and increased unburned hydrocarbon (HC) and carbon mono...
