Background technique:
In order to save the energy, improve the fuel economy of motor, supercharging is to improve one of main effective way of engine efficiency.The single cylinder diesel supercharging is because single cylinder diesel waste gas deficiency adopts exhaust gas turbocharge infeasible substantially, if adopt engine driven supercharging also will consider the design and the lubrication problem of the high rotating speed underdrive of pressurized machine chain.With the single cylinder diesel flywheel as rotor banding movable vane wheel compression air, effectively supercharging, and boundary dimension compactness, the pressurized machine working stability is reliability and durability.Though patent 200620157534.6 also proposes flywheel and drives gas compressor, diesel engine speed is not high general about 3000 rev/mins, and near the supercharging level that the gas compressor of its design obtains this rotating speed is very low, does not reach the supercharging requirement.
The model utility content:
The purpose of this utility model provides a kind of diesel engine air pump supercharging device, it carries out too for a short time improvement of supercharging level that the approach of supercharging brings to single cylinder diesel by pto such as flywheel, propose to carry out flywheel design, thereby solve the problem of single cylinder diesel supercharging with vortex air pump structure.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is made up of engine crankshaft 1, air pump supercharging device 2, air filter 3, intake duct 4, air outlet flue 5, air pump protecgulum 6, pump housing main body 7, diesel-engine body shell 8, diesel engine flywheel 9, air pump impeller 10, nut 11, air pump inlet 12, dividing plate 13, air pump outlet 14; Intake duct 4 and air outlet flue 5 are arranged on the top of diesel engine air pump supercharging device, intake duct 4 is arranged on the right side of air outlet flue 5, air pump protecgulum 6 is connected with air pump main body 7 by bolt, air pump main body 7 is by being bolted to above the diesel-engine body shell 8, diesel engine flywheel 9 ends are set to air pump impeller 10 outward or air pump impeller 10 are installed, air pump impeller 10 can design single-stage or two-stage form, air pump impeller 10 appearances are provided with static air pump runner, the air pump 12 gentle pump discharges 14 that enter the mouth are arranged on circumferentially, dividing plate 13 is arranged on air pump and enters the mouth between the 12 gentle pump discharges 14, avoid the gas short circuit, gap between dividing plate 13 and the air pump impeller 10 is 0.18-0.75mm, air pump inlet 12 is installed air filters 3, and air pump outlet 14 is connected to engine inlets 4 by pipeline.
The utility model mainly drives air pump by engine crankshaft 1 gas in the intake duct is carried out multistage compression, finally increases motor intake air density, makes the interior gas pressure of intake duct can reach tens kPas, thus effectively supercharging.
The utlity model has following beneficial effect: simple in structure, reliable operation, supercharging level height, especially be fit to the supercharging of single cylinder diesel, engine power is improved, reduce oil consumption, and reduce the generation of harmful emission of diesel engine thing.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2-Fig. 3 is the sectional view of air pump supercharging device 2;
Fig. 4 is the main sectional view of air pump supercharging device 2.
Embodiment:
Embodiment one: referring to Fig. 1-3, this embodiment by the following technical solutions: it is made up of engine crankshaft 1, air pump supercharging device 2, air filter 3, intake duct 4, air outlet flue 5, air pump protecgulum 6, pump housing main body 7, diesel-engine body shell 8, diesel engine flywheel 9, air pump impeller 10, nut 11, air pump inlet 12, dividing plate 13, air pump outlet 14; Intake duct 4 and air outlet flue 5 are arranged on the top of diesel engine air pump supercharging device, intake duct 4 is arranged on the right side of air outlet flue 5, air pump protecgulum 6 is connected with air pump main body 7 by bolt, air pump main body 7 is by being bolted to above the diesel-engine body shell 8, diesel engine flywheel 9 ends are set to air pump impeller 10 outward, air pump impeller 10 can design single-stage or two-stage form, air pump impeller 10 appearances are provided with static air pump runner, the air pump 12 gentle pump discharges 14 that enter the mouth are arranged on circumferentially, dividing plate 13 is arranged on air pump and enters the mouth between the 12 gentle pump discharges 14, avoid the gas short circuit, gap between dividing plate 13 and the air pump impeller 10 is 0.18-0.75mm, air pump inlet 12 is installed air filters 3, and air pump outlet 14 is connected to engine inlets 4 by pipeline.
Workflow: gas enters air pump by air filter 3, because flowing out, centrifugal force collides pump case again after being rotated the impeller suction, bounce-back enters impeller once more, exchange through multiple energy, thereby obtaining pressurized gas flows out from the air pump outlet, enter engine inlets by pipeline, finally realize engine booster.
The utility model mainly drives air pump by engine crankshaft 1 gas in the intake duct is carried out multistage compression, finally increases motor intake air density, makes the interior gas pressure of intake duct can reach tens kPas, thus effectively supercharging.
