Abstract
The utility model discloses a cylinder pressure sensor connecting device which consists of a spark plug type cylinder pressure sensor, a high-voltage wire and a plug; wherein, the spark plug type cylinder pressure sensor is arranged on the cylinder cover of an engine. The utility model is characterized in that the spark plug connection head of the spark plug type cylinder pressure sensor is communicated with a connection rod, and the connection rod connects with the high-voltage wire and the plug. Since the connection rod is slimmer and led outside the cylinder cover, a big gap is left between the connection rod and the cylinder pressure sensor signal line which is positioned in a spark plug installation hole, so as to protect the signal line of the cylinder pressure sensor from fragile fracture. The utility model is the cylinder pressure sensor connecting device with simplicity and practicality.
Description
Technical field
The utility model relates to a kind of cylinder pressure sensors coupling arrangement, especially relates to the installation of spark plug formula cylinder pressure sensors in the engine test and the device that spark plug is connected with cylinder separating line.
Background technology
The engine research and development constantly propose harsh demand from dynamic property, economy and discharging, and performance history is also just more and more paid attention to the control of burning.The cylinder pressure of monitoring is an engine thermal mechanics exploitation necessary parameter in the engine development test.For the measurement of spark-ignition engine cylinder pressure, use spark plug formula cylinder pressure sensors more convenient.But sensor signal lines is drawn from the spark plug next door, because the spark plug mounting hole that engine cylinder covers is very narrow and small again, use the general automobiles cylinder separating line directly to connect, sensor signal lines is ruptured because of pushing with cylinder cap at root and spark plug mounting hole oral area two places.Spark plug formula cylinder pressure sensors price is expensive especially, presses for reliable, safe installing and connecting apparatus at present.
Summary of the invention
The technical problems to be solved in the utility model is, in order to remedy the weak point that is connected between existing cylinder pressure sensors and the cylinder separating line, and provides a kind of safe and reliable, simple and practical cylinder pressure sensors coupling arrangement.
The utility model is to solve the problems of the technologies described above to adopt following technical scheme: a kind of cylinder pressure sensors coupling arrangement, comprise spark plug formula cylinder pressure sensors, hi-line and joint, cover at engine cylinder spark plug formula cylinder pressure sensors is installed.It is characterized in that: the spark plug connector of spark plug formula cylinder pressure sensors is electrically connected connecting link, and connecting link connects hi-line and joint.
For better protection cylinder pressure sensors signal wire, adopt one section thinner connecting link of diameter to be connected on the spark plug formula cylinder pressure sensors, and connect hi-line and joint beyond drawing cylinder cap.Can also finish the normal ignition of engine.
Good effect of the present utility model is, because connecting link is thin and draw beyond the cylinder cap, between cylinder pressure sensors signal wire in the spark plug mounting hole and the connecting link bigger space is arranged, the cylinder pressure sensors signal wire is easy fracture not, is a kind of simple and practical cylinder pressure sensors coupling arrangement.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is a cylinder pressure sensors coupling arrangement organigram.
Among the figure: 1. engine cylinder cover, 2. spark plug formula cylinder pressure sensors, 3. spark plug connector, 4. spark plug mounting hole, 5. connecting link, 6. hi-line, 7. joint, 8. signal wire, 9. the spark plug mounting hole oral area on the signal wire, 10. connecting link end.11. signal wire root.
Embodiment
Embodiment as shown in Figure 1, a kind of cylinder pressure sensors coupling arrangement comprises spark plug formula cylinder pressure sensors 2, hi-line 6 and joint 7, on engine cylinder cover 1 spark plug mounting hole 4 spark plug formula cylinder pressure sensors 2 is installed.The spark plug connector 3 of spark plug formula cylinder pressure sensors 2 is electrically connected connecting link 5, and connecting link 5 connects hi-line 6 and joint 7.
For better protection cylinder pressure sensors signal wire 8, adopt one section thinner connecting link 5 of diameter to be connected on the spark plug formula cylinder pressure sensors 2, and (the spark plug mounting hole oral area 9 on the signal wire is outer) connect hi-line 6 and joint 7 beyond drawing cylinder cap.The overcoat of connecting link 5 adopts elastomeric material, and the inner good copper sheet of conduction that adopts is made joint.Hi-line 6 adopts the general automobiles cylinder separating line, and joint 7 adopts the sparking-plug electrode of common form to get final product.
In order not allow the end 10 of connecting link 5 break signal wire root 11 places, cause damage, so reduce the length of connecting link 5 ends 10, further abdicate installing space for signal wire.
Claims (2)
1. a cylinder pressure sensors coupling arrangement comprises spark plug formula cylinder pressure sensors, hi-line and joint, covers at engine cylinder spark plug formula cylinder pressure sensors is installed; It is characterized in that: the spark plug connector of spark plug formula cylinder pressure sensors is electrically connected connecting link, and connecting link connects hi-line and joint.
2. cylinder pressure sensors coupling arrangement according to claim 1 is characterized in that: described connecting link is connected on the spark plug formula cylinder pressure sensors, and connects hi-line and joint beyond drawing cylinder cap.
