Abstract
The invention relates to an aerator for a plateau ship diesel, which comprises: a compressor in transmission connected with the diesel and a first intake filter arranged on an air inlet of the compressor, wherein an air outlet of the compressor is connected with a first air inlet of a one-way intake valve, and an air outlet of the one-way intake valve is connected with an air inlet of a turbocharger in the diesel. According to the aerator of the invention, the compressor is used for increasing the intake pressure and amount of the diesel in a low rotating speed area. During operation, the diesel starts up and drives the compressor to operate so as to generate intake pressure, and the air is sucked in by the first intake filter. When the rotating speed of the diesel reaches 200 r/min, the suction amount generated by the turbocharger of the diesel is larger than the intake amount provided by the compressor, therefore, a second air inlet of the one-way valve is opened owing to the action of backpressure, and simultaneously, the first air inlet is closed off and the diesel realizes the intake from the second intake filter. The device of the invention settles the defect of insufficient air supply of the turbocharger in the low rotating speed area.
Description
Technical field
The present invention relates to the technical field of use for diesel engine oxygen-increasing device, specifically is a kind of plateau diesel engine for ship oxygen-increasing device.
Background technique
Turbosupercharger is to utilize diesel exhaust gas energy drives turbine, drives the device that gas compressor improves diesel engine intake pressure.
Turbosupercharger is actually a kind of air compressor, increases air inflow by pressurized air.It is that the waste gas inertia impulsive force that utilizes motor to discharge promotes the interior turbine of turbine chamber, and turbine drives coaxial impeller again, and the air that the impeller force feed is sent here by the air-strainer pipeline makes it supercharging and enters cylinder.When engine speed speeds, the waste gas velocity of discharge and secondary speed also speed synchronously, impeller just compresses more air and enters cylinder, the pressure of air and density increase the more fuel that can burn, the rotating speed of corresponding increase fuel quantity and adjustment motor just can increase the output power of motor.
The plateau atmospheric pressure has reduced 40-42% than zero height above sea level standard atmospheric pressure, so air density is thin, and the per unit volume oxygen content descends significantly, causes power because of anoxic during engine operation and moment of torsion descends automatically.
According to " the turbo-charged diesel high altitude low air pressure performance test research " that the military traffic Liu Ruilin of institute in Tianjin teaches and the Qin De researcher of Tianjin Inst. of IC Engine is done, show that change of elevation is less and bigger to the influence of low velocity zone power character to the power character influence of diesel engine high velocity, the rotating speed of peak torque correspondence moves to high velocity gradually along with height above sea level raises.
The diesel engine peak work capacity seriously descends in low velocity zone, especially in the time of diesel engine speed 1400-1600 rev/min, ships and light boats overcome ships and light boats and play sliding necessary power and moment of torsion because of diesel engine can not provide, thereby cause ships and light boats can not normally play cunning at this speed stage, therefore how in the time of diesel engine speed 1400-1600 rev/min power and the moment of torsion that is lost being remedied, is the technical problem that related domain will solve.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of simple in structure, be suitable for increasing diesel engine in the suction pressure and the air inflow of low rotation speed area and guarantee that finally diesel engine has the plateau diesel engine for ship oxygen-increasing device of enough power and moment of torsion in low rotation speed area.
In order to solve the problems of the technologies described above, the invention provides a kind of plateau diesel engine for ship oxygen-increasing device, it comprises: with first air intake filter on diesel engine compressor that is in transmission connection and the suction port of being located at compressor, the air outlet of compressor is connected with first suction port of a breather cheek valve through tracheae, second suction port of this breather cheek valve is provided with second air intake filter, and the air intlet of the turbosupercharger in the air outlet of this breather cheek valve and the diesel engine is connected.
Technique scheme of the present invention has the following advantages compared to existing technology: in the diesel engine for ship oxygen-increasing device of plateau of the present invention, compressor is attached on the suction port of the turbosupercharger in the diesel engine, increases suction pressure and the air inflow of diesel engine in low rotation speed area.Its working principle is as follows: diesel engine starting also makes compressor starts work, produces suction pressure, and air is sucked by first air intake filter.Under the effect of the suction pressure that compressor produces, first air inlet open of one-way valve, second inlet close, air only suck from first suction port of one-way valve.When diesel engine speed arrives 2000 rev/mins, the gettering quantity that the turbosupercharger of diesel engine begins to produce is greater than air inflow that compressor provided, therefore second suction port of one-way valve is opened because of the back pressure effect, closes first suction port simultaneously, and diesel engine is from the second air intake filter air inlet.This programme has remedied turbosupercharger low rotation speed area air feed defect of insufficient.
Description of drawings
For the easier quilt of content of the present invention is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the present invention is further detailed explanation, wherein
