Description
Technical field
The utility model relates to a kind of fuel limit device, relates in particular to a kind of fuel limit device that is applied on the automotive Diesel engine.
Background technique
Rock gas is as a kind of very promising alternative fuel, and the application on diesel engine is to alleviating the petroleum resources shortage, and it is significant to reduce the discharging aspect.On the mixed combustion vehicle, the application of rock gas on diesel engine relates to the problems such as the structure of former diesel oil fuel limit device and layout.Diesel engine of the prior art, for example EGR state three diesel engine limit oil machine structure is at the limit oil axle of oil pump for engine an oily handle of limit to be installed, when this diesel engine is limit oil, need manually pull handle, inconvenient operation is pulled angular displacement owing to can't accurately controlling in addition, and it is excessive to pull angle, so that diesel engine is directly flame-out, not only can't reaches the purpose of limit oil but also can bring potential safety hazard.
The model utility content
For deficiency of the prior art, the utility model aims to provide a kind of diesel engine fuel limit device that adopts automation control, and this fuel limit device can be accurate, controls reliably the limit oil of diesel engine.
In order to address the above problem, diesel engine fuel limit device of the present utility model is characterized in that comprising: Z-type is limit oily handle, stepper motor and support, and this Z-type limits oily handle to comprise the one handle bar, one end of this handlebar is provided with first-hand shaft arm, and the other end is provided with second-hand's shaft arm;
Z-type limits oily handle to be connected with the oily axle of the limit in the diesel engine oil pump by first-hand shaft arm; Described stepper motor is fixed on the diesel engine by support, and the motor head of this stepper motor and described Z-type are limit second-hand's shaft arm butt of oily handle;
Motor head on the vehicle body ECU control step motor promotes second-hand's shaft arm, thereby the limit oil axle in the control diesel engine oil pump rotates.
Preferably, described Z-type limits second-hand's shaft arm of oily handle to be provided with bearing, the motor head on the described stepper motor and the outer circumferential face butt of bearing.
Preferably, described Z-type limits the first-hand shaft arm of oily handle to be provided with handle head, and first-hand shaft arm is connected with the oily axle of the limit in the diesel engine oil pump by this handle head.
Motor head on the vehicle body ECU control step motor promotes second-hand's shaft arm reciprocally swinging, thereby the limit oil axle in the control diesel engine oil pump rotates, and plays the effect of limit oil.Because the exactly displacement of the motor head of control step motor of vehicle body ECU is limit oily handle by Z-type, can indirectly control the angular displacement size of the limit oil axle in the diesel engine oil pump, thereby accurately, control reliably the limit oil of diesel engine.
Description of drawings
Fig. 1 is the structural representation of the diesel engine fuel limit device in the utility model;
Fig. 2 is the schematic side view of Fig. 1;
Fig. 3 is the structural representation that the Z-type in the utility model is limit oily handle.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
In conjunction with Fig. 1 to Fig. 3, a kind of diesel engine fuel limit device of the present utility model, this device is at original automotive Diesel engine, a kind of mechanism of for example installing additional on EGR state three diesel engine is to reach the purpose of limit oil.This device comprises that a Z-type limits oily handle 1, stepper motor 2 and support 3, and wherein to limit the middle part of oily handle 1 be a handlebar 13 to this Z-type, and an end of this handlebar 13 is provided with first-hand shaft arm 12, and the other end is provided with second-hand's shaft arm 14.Z-type limits oily handle 1 to be connected with the oily axle 41 of the limit in the diesel engine oil pump by first-hand shaft arm 12, this is limit on the oily axle 41 and also is provided with woodruff key and spring, can be so that limit oily axle 41 to rotate rear self-return, wherein the limit oil machine structure in the oil pump for engine is the common practise of related domain, no longer is described in detail here.Support 3 is installed on the oil pump 4, fixes by the bolt on the former car, and described stepper motor 2 is fixed on by support 3 on the oil pump 4 of diesel engine, and the motor head of this stepper motor 2 limits second-hand's shaft arm 14 of oily handle 1 to contact or butt with described Z-type.Motor head on the vehicle body ECU control step motor 2 promotes second-hand's shaft arm 14, second-hand's shaft arm 14 reciprocally swingings, thus the limit oil axle 41 in the control diesel engine oil pump rotates, and plays the effect of limit oil.Because the exactly displacement of the motor head of control step motor of vehicle body ECU is limit oily handle by Z-type, can indirectly control the angular displacement size of the limit oil axle 41 in the diesel engine oil pump, thereby accurately, control reliably the limit oil of diesel engine.
Preferably, described Z-type limits second-hand's shaft arm 14 of oily handle 1 to be provided with bearing 141, the motor head on the described stepper motor 2 and the outer circumferential face butt of bearing 141.Because this bearing 141 can rotate around second-hand's shaft arm 14, when the motor head of stepper motor promotes second-hand's shaft arm 14, can reduce friction, raises the efficiency.In addition, described Z-type limits the first-hand shaft arm 12 of oily handle 1 to be provided with handle head 121, and first-hand shaft arm 12 is connected with the oily axle of the limit in the diesel engine oil pump by this handle head 121, so that Z-type limits oily handle to be connected more firm with the oily axle of limit.
