Background technique
People's Transportation Press's vehicle energy saving and the one book introduction of environmental protection practical technique, the HC compound is relevant with compression temperature with black smoke, intake temperature is high more, air density is big more, compression temperature is high more, and the combustion-supporting speed of compression ignite is fast more thorough more, and it is few more that HC compound, black smoke produce.
Fig. 1 is Chinese patent specification CN 1424497A, disclosed a kind of heat-flash wind air intake pressurized energy-saving environmental protection device schematic representation that draws, drawing heat-flash wind air intake pressurized energy-saving environmental protection device is installed between water tank 101 and the motor 106, direction-changing type fan 102 is installed on the water pump spindle of motor 106, this fan can become axial wind the footpath aweather, said direction-changing type fan is the V-type fans, the two sides air draught of V-type fans energy, collect two sides wind in the centre, also but flabellum and substrate are one, the exhaust port place of said direction-changing type fan and a vortex type air inducing circle 103 combinations, the hot air inlet place of this vortex type air inducing circle connects the toroidal blower cover, be provided with guide plate in the vortex cavity of air inducing circle, it between the guide plate independent vortex type air inlet duct, the hot-air outlet of said air inducing circle connects induced air pipe 104, the air-strainer 105 of this induced air pipe sending and receiving motivation 106.
Because this kind device is introduced hot air and is come from the heat that water tank distributes and form, generally air temperature is lower than 100 ℃, the air temperature that enters cylinder again behind induced air pipe, air-strainer has descended many, can not form the combustion-supporting gas of higher temperature, do not reach combustion-supporting effect, the thermal efficiency of insufficient diesel engine still of causing burning is not high, and the reliability of actual motion is not high.
The model utility content
The technical problem that solves: the technical problems to be solved in the utility model provides a kind of heat exchange device for air of diesel engine, it can provide temperature more than 100 ℃ even the combustion-supporting air of higher temperature, make the oil inflame of diesel engine more abundant, improve utilization efficiency, save oil consumption, reduce discharge of harmful gases effectively, reduce the pollution that atmosphere is caused, and reduce the noise of diesel engine.
Technological scheme: for solving the problems of the technologies described above, technological scheme that the utility model adopts is conceived substantially: the heat-exchange device that increases a kind of air in diesel engine confession, vent systems, cool air is after heat-exchange device carries out heat exchange, become the high temperature combustion-supporting air, directly enter cylinder, make cylinder intermediate fuel oil energy sufficient combustion.
The heat exchange device for air of diesel engine of the present utility model is characterized in that it is made up of air-strainer 1, suction tude 5, outlet pipe 4 and heat exchanger 7; Described heat exchanger 7 comprises radiator tube group 3 and heat exchanger housing 2, described heat exchanger housing 2 seals, respectively there is the space of a sealing at its two ends, the radiator tube group of forming with a plurality of radiators 3 is communicated with therebetween, heat exchanger housing 2 wraps in radiator tube group 3 wherein, and forms interlayer with radiator tube group 3; The space of the sealing at described two ends is communicated with air-strainer 1, suction tude 5 respectively, and the middle part of described heat exchanger housing 2 is communicated with outlet pipe 4 and exhaust outlet 6 respectively.
The heat exchange device for air of above-mentioned diesel engine, its suction tude 5 links to each other with cylinder with outlet pipe 4, and the cool air that sucks from air-strainer 1 enters radiator tube group 3; The high-temperature tail gas of discharging from cylinder 8 is entered the heat exchanger housing by outlet pipe 4, after cool air in the radiator tube group 3 and high-temperature tail gas carry out heat exchange, becomes the high temperature combustion-supporting air and sucks in the cylinder 8 through suction tude 5.High-temperature tail gas after the heat exchange is discharged through exhaust outlet 6.
The beneficial effects of the utility model are: adopt heat exchange device for air of the present utility model, because the high-temperature tail gas in the engine cylinder is directly entered in the heat-exchange device by outlet pipe, temperature losses is very little, combustion air temperature is also very high after heat exchange like this, and the high temperature combustion-supporting air does not need through links such as air-strainer, directly keep entering the cylinder of diesel engine through suction tude, the combustion air temperature that enters cylinder is unrestricted, fuel oil can be burnt in cylinder more fully, save oil consumption, reduce discharge of harmful gases effectively, reduce the pollution that atmosphere is caused, improve the moving rate of use of diesel engine, and reduced the noise of diesel engine.
