Abstract
The utility model relates to a secondary combustion gas intake system for diesel engine waste gas, in particular to a device for collecting waste gas from a diesel engine and capable of secondary gas intake. The device comprises a cylinder assembly, a gas inlet pipe and an exhaust pipe, wherein the gas inlet pipe is connected to one end of the cylinder assembly and the exhaust pipe is connected to the other end of the cylinder assembly. A circular pipe is arranged between the gas inlet pipe and the exhaust pipe; a threaded guide groove is arranged in the circular pipe; one end of the circular pipe is connected onto the gas inlet pipe; the other end of the circular pipe is connected onto the exhaust pipe; and the two ends of the circular pipe are communicated with the gas inlet pipe and the exhaust pipe. By the aid of the device, diesel consumption of a diesel engine can be decreased by 14%, and smoke emission is not more than 261g/km.
Description
Technical field
The utility model relates to a kind of air inlet system, but particularly a kind of device that is used for collecting on the diesel engine waste gas and secondary air inlet.
Background technique
Common agricultural diesel oil motor great majority are by pressurized air fuel high pressure to be sprayed in the high temperature cylinder, make the burning of fuel spontaneous ignition, because fuel is by the direct injection inlet casing, so occur high density area and low density area in the cylinder easily, be easy to generate particulate matter at high density area, in addition, because the temperature of exhausting air is lower, catalyst converter is difficult to bring into play effect, cause in the exhaust emissions harmful matter oxynitrides content higher, the mankind's living environment, self health etc. are caused great harm.
The model utility content
In order to solve existing common agricultural equipment Diesel engine incomplete combustion, contain the high problem of oxynitrides in the tail gas, the utility model provides a kind of diesel exhaust secondary combustion gas handling system.
The utility model comprises cylinder assembly, suction tude, outlet pipe, described suction tude is connected an end of described cylinder assembly, described outlet pipe is connected the other end of described cylinder assembly, between described suction tude and outlet pipe, pipe is set, in described pipe, thread guide groove is set, one end of described pipe is connected on the suction tude, and the other end of described pipe is connected on the described outlet pipe, is communicated with between the two ends of described pipe and suction tude, the outlet pipe.
Usually the black smoke of single cylinder diesel directly is discharged into, but connection one is provided with the pipe of helical guide groove between suction tude and outlet pipe, pipe is passed black smoke back suction tude again, carries out the burning of secondary tar, exhaust cigarette temperature height, with its resorption and cool air mixing once more, play diesel spray fuel oil preignition, it is powerful to do work, and uses this device, can make the diesel engine fuel consumption reduce 14%, smoke emission is not more than 261g/km.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1, cylinder assembly, 2, suction tude, 3, outlet pipe, 4, pipe, 5, thread guide groove.
Embodiment
As shown in Figure 1, this diesel exhaust secondary combustion gas handling system, comprise cylinder assembly 1, suction tude 2, outlet pipe 3, suction tude 2 is connected an end of cylinder assembly 1, and outlet pipe 2 is connected the other end of cylinder assembly 1, between suction tude 2 and outlet pipe 3 pipe 4 is set, thread guide groove 5 is set in pipe 4, one end of pipe 4 is connected on the suction tude 2, and the other end of pipe 4 is connected on the outlet pipe 3, is communicated with between the two ends of pipe 4 and suction tude 2, the outlet pipe 3.
Claims (1)
