Cylinder is connected, and flow divider transports pipeline and is connected with reforming reactor by second, and air inlet pipe is connected with cylinder, and reforming reactor passes through
Reformate transports pipeline and is connected with air inlet pipe.
The beneficial effects of the invention are as follows：1st, the present invention reduces Diesel NOx discharge using EGR Technology；2nd, fuel
Micro-molecular gas are generated after generation reforming reaction, can improve burning, reduce the discharge of pollutant especially solid particulate matter,
The thermal efficiency of diesel engine can be improved simultaneously；3rd, the present invention extraneous need not provide water, it is not required that heating water forms steam
Firing equipment, it is contemplated that contain water vapour in high-temperature tail gas, the present invention proposes and tail gas directly is passed through into reforming reactor, makes it
The method that hybrid concurrency gives birth to reforming reaction is contacted in reforming reactor with fuel；4th, using fuel there is reforming reaction in the present invention
The method of tail gas heat quantity is absorbed to recycle the energy contained in tail gas；5th, structural modification of the present invention to diesel engine
It is very smaller, it is easy to utilize.One remarkable advantage of technology proposed by the present invention is extraneous need not to provide water, Yi Jijia
Hot water forms the firing equipment of steam.
