The low-emission diesel engine system can lower the requirements on supercharging intercooling, EGR intercooling of the diesel engine, can reduce the oil consumption of the engine, can reduce the emission, and solves the problems that the existing system for reducing the emission of the diesel engine has high requirements on the supercharger intercooling and the EGR intercooling, and the preparation is difficult.
Description
Technical field
The utility model relates to a kind of diesel engine system of low emission.
Background technique
In the existing technology, diesel engine often can not well be taken into account and fall oil consumption and settling-discharging.The emphasis of Exhaust Control for Diesel Engine and difficult point are NOx and the particle concentrations of coordinating in the waste gas.Existing method reduces the particle generation as improve burning through the matched with pressurization device, reduces the generation of NOx etc. through exhaust gas recirculation (EGR) technology.But the existing system that reduces diesel emission is to requirement height cold among the cold-peace EGR in the pressurized machine, and the preparation difficulty is big, if reduce cold requirement among the cold-peace EGR in the pressurized machine, the emission effect that reduces NOx and particle concentration is poor.
Chinese patent notification number CN101509440A; August 19 2009 day for announcing; Disclose a kind of low discharging system of diesel engine used not on road, comprised the diesel engine main frame that pump in upright arrangement is installed, said diesel engine main frame is provided with the exhaust passageway that is used for the discharge of burning chamber waste gas; Also comprise gas recirculation system, be used for carrying waste gas, be more suitable for the applying working condition of diesel engine used not on road to the firing chamber.But this low discharging system of diesel engine used not on road is high to requirement cold among the cold-peace EGR in the pressurized machine, and the preparation difficulty is big, if reduce cold requirement among the cold-peace EGR in the pressurized machine, the emission effect that reduces NOx and particle concentration is poor.
The model utility content
The purpose of the utility model is to provide a kind of diesel engine system of low emission, and the system that has solved existing reduction diesel emission is high to requirement cold among the cold-peace EGR in the pressurized machine, the big problem of preparation difficulty.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of low-emission diesel system comprises diesel engine, suction tude and outlet pipe; Suction tude is provided with by exhaust-driven pressurized machine in the outlet pipe, also is provided with intercooler on the suction tude, interconnects through the EGR valve between suction tude and outlet pipe; Said diesel engine is provided with water tank; Water tank connects water pump through pipeline, and the water pump external pipe is provided with nozzle, and nozzle inserts suction tude.Hydraulic spray nozzle is positioned at the suction tude at pressurized machine and EGR valve rear portion, and the water in the water tank sprays into suction tude after the water pump pressurization, and water smoke can effectively reduce intake temperature; Increase air inflow; Improve engine power, the evaporation of water smoke in suction tude can reduce the requirement of gas handling system to intercooler; Water smoke evaporates in the firing chamber, has increased the total thermal capacity of gas, reduces FT, has reduced the generation of NOx.
As preferably, the lubricating oil path of said diesel engine and water pump is interconnected.Be interconnected through lubricating oil path, can make things convenient for feed water pump to provide and use lubricant oil, need not to increase the lubricating oil path pipeline.
As preferably, said water pump connects controller.The spraying moment and spray amount are determined that by diesel engine condition through controller, the intelligent control of whole system need not manual operation.
As preferably, said controller connects data/address bus.Parameters such as the needed engine speed of controller, torque, engine water temperature, EGR state can be obtained by the data/address bus of car load and motor, have reduced the use of sensor, have reduced system cost.
The beneficial effect of the utility model is: (1), hydraulic spray nozzle are arranged in intake duct, and the water smoke evaporation heat absorption that sprays into has reduced intake temperature.A small amount of water smoke that does not evaporate fully then can be participated in burning, has the effect that reduces oil consumption and discharging.Be different from the firing chamber and directly spray water or use the diesel oil emulsification for preparing in advance, the intake duct spray technique had both kept fuel-economizing, had reduced the advantage of discharging, and it is lubricated can not destroy the firing chamber simultaneously, does not use emulsifier, has reduced cost; (2), the spraying moment and spray amount are determined that by diesel engine condition the intelligent control of whole system need not manual operation; (3), the required input of controller obtained by data/address bus, reduced the use of sensor, reduced system cost.
