Embodiment
Please consult Fig. 4, and Fig. 5 simultaneously, it is respectively this schematic representation of creating a preferred embodiment and choke valve block thereof the illustrative view when closing.Present embodiment is a kind of air inlet system of locomotive engine, includes: a cylinder head 10, a variable intake manifold 20, an insulator 50, an and control unit 60.
As shown in the figure, cylinder head 10 separates out two intake ducts 11 by a partition wall 13 in it.Variable intake manifold 20 includes an intake manifold 30, reaches a variable air intake device 40, and intake manifold 30 is communicated with two intake ducts 11 of cylinder head 10, is installed with an oil supply unit 21 on the intake manifold 30.Variable air intake device 40 includes one, and to be mounted on choke valve block 41 in the intake manifold 30, rotating disk that an actuator 45, is subjected to actuator 45 rotary driving 43, one affixed and be subjected to running shaft 42 that rotating disk 43 drives, an operating stem 44, an and stop block 35 that is fixedly arranged on the intake manifold 30 with choke valve block 41, and two ends of operating stem 44 connect actuator 45 and running shaft 42 respectively.
The principle of controlling of variable air intake device 40 is to control the start of actuators 45 by control unit 60, the 44 front and back slippages of actuator 45 controllable operation bars, and then be converted to control running shaft 42 left rotation and right rotation, again so control choke valve block 41 rotations one angle with two intake ducts, 11 one of latch-release cylinder head 10.As for the function of stop block 35 is can be in order to the angle of swing of restriction rotating disk 43, and then reaches the function of the angle of swing of restriction choke valve block 41.Choke valve block 41 positions shown in Figure 5 are two intake ducts, 11 one of closing cylinder head 10, and this moment, locomotive engine was in low speed state, only need less air inlet sectional area, and mixed oil and gas only enters the one of two intake ducts 11 by this, and preferable vortex effect is also arranged.
In the present embodiment, control unit 60 can be integrated in the electronic control unit (ECU) of locomotive, can reach the effect of simplifying number of parts.And stop block 35 is an integral structure with intake manifold 30.
As shown in Figure 4, insulator 50 is fixedly arranged between cylinder head 10 and the variable intake manifold 20, and it is mat two bolts 22 with variable intake manifold 20, insulator 50, and cylinder head 10 lockings.In the present embodiment, insulator 50 is the insulator 50 of bakelite material, can block the heat that is transmitted by cylinder head 10, avoids variable air intake device 40 stuck because of being heated, and can't operate.And insulator 50 has a projection 51, and projection 51 and variable air intake device 40 corresponding formation make the air inlet path section of not having poor, can increase the separation effect of high low speed gas flow.
Present embodiment intake manifold 30 is a modular integral structure with variable air intake device 40, thereby can omit known seal ring, and can the reduction group found man-hour and error, and then reduces whole cost.
Please consult Fig. 4, and Fig. 6 more simultaneously, it is respectively the schematic representation of the utility model one preferred embodiment and choke valve block thereof the illustrative view when opening.When locomotive engine during in high rotating speed, control unit 60 controlled actuator 45 starts this moment, and then control choke valve block 41 rotations one angle, choke valve block 41 positions shown in Figure 6 are that two intake ducts 11 of cylinder head 10 are all unlatching, and bigger air inlet sectional area is arranged.
From the above, the big I of the utility model air inlet sectional area cooperates the rotating speed height of locomotive engine and adjusts.When locomotive engine was in fast state, two intake ducts were all opened, and can obtain bigger air inlet sectional area; When locomotive engine is in lower-speed state, two intake duct one are closed, then can obtain less air inlet sectional area, and preferable vortex effect is arranged, consumption improvement is respond well, so under the universe rotating speed of locomotive engine, all can take into account the requirement of its intake efficiency, and the effective intake efficiency of elevator car engine.
The foregoing description only is to give an example for convenience of description, and the interest field that this creation is advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
