Description
Technical field
The utility model relates to a kind of device for carrying out humid control to air inlet adjusting system of engine, particularly discloses a kind of engine charge humidity conditioner, belongs to automated test device technical field, is suitable for the control of various engine charge humidity.
Background technique
At present, motor carries out getting more and more in performance and emission testing having adopted air inlet adjusting system of engine, namely controls engine aspirating system air inlet at the standard conditions, comprises and controls suction pressure, intake temperature, ambient humidity under standard conditions.Effect ensures under same external condition, and whether the performances such as the Economy of measurement and fair evaluation motor and discharge, to determine whether motor reaches the standard-required index of the performances such as discharge, can provide production licence.There is the NBS about performance tests such as motor discharges at present, the more harsh standard of Ye You different company.In standard, no matter major requirement tests local atmospheric pressure, which kind of state temperature, humidity be in, and needs to control suction pressure a fixing value or there is certain change setting range; Control intake temperature a fixing value or there is certain change setting range; Control ambient humidity a fixing value or there is certain change setting range.Wherein because ambient humidity is very large on engine discharging amount impact, so particularly important to the control of humidity.In order to reach the control objectives to ambient humidity, main employing two kinds of schemes in the past, a kind of is adopt the scheme revising atmospheric conditions, this scheme does not control inlet air conditions, only revises test result, mainly empirical correlation correction, this method really cannot know the measured result under standard inlet air conditions, very large deviation may be caused, be a kind of expedient scheme, can only general test be carried out; Another kind in air inlet, adds full mode of closing steam by air inlet to control ambient humidity; This scheme needs strict employing isothermal humidification process, adopt humidity transducer feedback control humidity, due to difficulties such as on-the-spot steam generating devices, the full situation of closing or satiating the generation of conjunction steam may be had, cause humid control difficulty, particularly humidity sensor measurement precision is not high, so control procedure is complicated, cost is high, and control accuracy is not easy to ensure.
Summary of the invention
The purpose of this utility model solves engine charge humid control scheme in prior art to adopt the mode of steam humidification and humidity transducer feedback control, make control procedure complicated, control accuracy is low, the problem of poor reliability, design a kind of engine charge humidity conditioner, adopt the method controlled humidity controlling dew point temperature in engine charge, and then the mode being heated to the intake temperature required controls ambient humidity, by the controlled humidity process of complexity, resolve into two temperature controlled processes, control procedure is simple, control range is wide, and control accuracy is high.
The utility model is achieved in that a kind of engine charge humidity conditioner, comprise engine charge air channel, the air inlet adjustment valve at suction port place, air channel and the blower fan of air channel back segment, it is characterized in that: described air channel is provided with engine charge humidity conditioner, described engine charge humidity conditioner comprises the electric heater being in suction port place, air channel, be in wet-membrane humidifier engine charge being carried out to equal-enthalpy humidifying in the middle part of air channel, control air-cooler and the air heater of engine charge dew point temperature, air channel end after blower fan is also provided with pressure transducer, temperature and humidity sensor and thermal gas flowmeter.The temperature transducer of the dew point temperature of display engine charge is also set in described engine charge air channel.Also air-strainer is provided with in front end, described engine charge air channel.
The utility model has the following advantages compared with prior art:
1, go for simulated engine and carry out humidity and humid test, create the inlet air conditions of standard;
2, adopt dew point control methods to control humidity, substantially increase control accuracy;
3, humid control and temperature separate, substantially increase repeatability.
