Convenience is created for use of transportation and construction equipment in the western plateau area in China, meanwhile, pollutant emission is reduced and economy is improved to some extent.
Description
Technical field
The utility model relates to power engine technical field, specifically a kind of plateau type power engine that adopts intake oxygen enrichment form.
Background technique
At present, known power engine, uses well in Plain operating mode (below 3000M), but while using in plateau section, because plateau atmospheric pressure is low, incomplete combustion, cause the equipment dynamic that plateau is used to decline and oil consumption increase, and exhaust emission is serious.The plateau type power engine of now knowing, solves the problems referred to above by increase gas compressor, minimizing fuel delivery, but when this equipment is applied to Plain operating mode, there will be again fuel feeding and the phenomenon that supplies unsaturated vapor.This contradiction causes cannot general operating mode for the power engine of Plain operating condition design and power engine for plateau operating condition design, during use, to user, brings great inconvenience.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of intake oxygen enrichment formula plateau type power engine, makes it in the situation that not changing Plain performance of operating condition, still can be applicable to plateau operating mode.
For achieving the above object, the utility model comprises power engine cylinder body, it is characterized in that: in the intake duct of power engine cylinder body, oxygen jet is installed, oxygen jet is connected with oxygen cylinder through jet pipe, and the flow control Proportional valve of being controlled by flow PID controller and the electromagnetic switch valve of being controlled by magnetic switch PID controller are installed in series on jet pipe.
The air inlet pressure sensor of installing on described intake duct is connected with flow PID controller by pressure signal line, and flow PID controller is connected with flow control Proportional valve by guide line one.
The speed probe of installing on described power engine cylinder body is connected with magnetic switch PID controller by tach signal line, and magnetic switch PID controller is connected with electromagnetic switch valve by guide line two.
The utility model increases an oxygen jet on the intake duct of existing power engine cylinder body, by the oxygen cylinder installed on equipment to power engine intake duct delivering oxygen, increase the oxygen purity of power engine air inlet, to guarantee sufficient combustion, overcome under altitude environment because oxygen feeding amount is not enough, cause power engine cylinder combustion surge pressure to decline, and then make situation about being short of power.
The utility model is subject to PID(proportional-integral-differential by installing on the pipeline of delivering oxygen) electromagnetic switch valve and the flow control Proportional valve controlled, control oxygen supply time and oxygen flow.Power engine is in the work of plateau operating mode, and in the time of need to increasing oxygen, solenoid valve is opened delivering oxygen pipeline, and flow control Proportional valve is controlled oxygen supply flow according to air pressure.When power engine is during in idling, shutdown or Plain operating mode, oxygen therapy pipeline is closed.
The utility model compared with prior art, can be so that power engine all can compatiblely use under Plain, the various operating modes in plateau, conversion arbitrarily.For the use of China's western plateau section transportation and construction equipment, create convenience, reduced disposal of pollutants simultaneously, improved to a certain extent Economy.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model is provided with oxygen jet 14 in the intake duct 2 of power engine cylinder body 1, and oxygen jet 14 is connected with oxygen cylinder 8 by jet pipe 15.On jet pipe 15, be installed in series flow control Proportional valve 7 and electromagnetic switch valve 9, to control oxygen supply time and oxygen-supplying amount.The air inlet pressure sensor 3 being arranged on intake duct 2 is connected with flow PID controller 5 by pressure signal line 4, and flow PID controller 5 is connected with flow control Proportional valve 7 by guide line 1.The speed probe 13 being arranged on power engine cylinder body 1 is connected with magnetic switch PID controller 11 by tach signal line 12, and magnetic switch PID controller 11 is connected with electromagnetic switch valve 9 by guide line 2 10.Described flow PID controller 5 is flow PID(proportional-integral-differential) controller, magnetic switch PID controller 11 is magnetic switch PID(proportional-integral-differential) controller.
The utility model is after power engine energising start, magnetic switch PID controller 11 detects the rotating speed of power engine by speed probe 13, when power engine rotating speed surpasses setting value (being generally 1000rpm), control electromagnetic switch valve 9 and open, start to power engine oxygen supply.
Power engine enters after the operating mode of plateau, the suction pressure that flow PID controller 5 detects in intake duct 2 by air inlet pressure sensor 3 reduces, during lower than setting value (being generally normal pressure value under the operating mode of Plain), flow control Proportional valve 7 is opened a certain amount of oxygen to power engine is provided.Its proportional quantities is associated with actual measurement suction pressure value, and observed pressure value is lower, and air demand is larger.Observed pressure value is higher, and air demand is less, when observed pressure value is greater than setting value, that is to say when power engine 1 has entered Plain operating mode by plateau,, flow control Proportional valve 7 is in closed condition, and air demand is zero.
Power engine is finished the work and is reverted to when idle, is also power engine rotating speed while being less than 1000rpm, and magnetic switch PID controller 11 detects power engine rotating speed lower than setting value, controls electromagnetic switch valve 9 and closes, oxygen feeding stop.
When power engine power-off is shut down, electromagnetic switch valve 9 and flow control Proportional valve 7 are all in closed condition.
The utility model is by the power engine in Plain performance, oxygen system being installed, and controls oxygen supply time and flow by PID controller, makes power engine can meet the performance requirement of Plain operating mode, can meet again the usage requirement of plateau operating mode.
