One light source provides shooting needed photometric brightness in engine cylinder;
One image receiving and displaying device, receive and show by the wireless pinhole cameras of multi-angle take, image in the engine cylinder that wireless signal transmits.
The structural feature of the utility model carbon on engine observation device also is:
Described sampling mechanism is set to tubular shell, integrated being arranged in the tubular shell of the wireless pinhole cameras of described light source and multi-angle.
In described tubular shell, setting can be along the axially movable rod member of housing, and the afterbody of described rod member extends in outside, and the front end of rod member is used to be provided with light source and the wireless pinhole cameras of multi-angle.
The described rod member front end that is used to be provided with light source is two bar heads of " V " font for supportting to rise, and light source is two point source of light, and two point source of light are fixedly installed on two bar heads.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model can be observed in the engine cylinder and the carbon distribution situation of valve position simply and effectively, and it is simple in structure, with low cost, easy to use.

Below by embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1 and Fig. 4, present embodiment is to be exploration hole, wireless pinhole cameras 1 of light source 7, multi-angle and the wireless signal transmitter installation 2 can be inserted in the exploration hole be set with engine spark plug hole 10, with light source 7 in engine cylinder and the valve position the required photometric brightness of shooting is provided, be the transmission signal of wireless signal transmitter installation 2 with the photographic images of the wireless pinhole cameras 1 of multi-angle.
Referring to Fig. 3,, need supporting setting to be respectively applied for picture receiver 14 and the display device 15 that receives and show photographic images in order to obtain image.
In concrete the enforcement, as shown in Figure 1, setting can be inserted in the tubular shell 6 in the engine spark plug hole 10, and light source 7, multi-angle is wireless pinhole cameras 1 are together with wireless signal transmitter installation 2 integrated being arranged in the tubular shell 6.
As Fig. 1, Fig. 2, in tubular shell 6, light source 7 is two light sources, but being two light sources, two light sources are separately positioned on the front end that " V " shape bar 8 is controlled in opening and closing, " V " shape bar 8 is fixedly installed on the annular base 4, support to keep dehiscing aperture with spring 9 between two bars, " V " shape bar 8 is connected along the front end of the control push rod 5 of the axial setting of tubular shell 6, the afterbody of control push rod 5 extends in the outside of tubular shell 6, can control two folding angles between the point source of light by spring 9 and moving of control push rod 5, with better raising shooting clearness, two bars with " V " type bar 8 when merging combine, with the diameter of control tubular shell 6, make it possible to more convenient stretching into and observe carbon distribution in the firing chamber.Annular base 4 and tubular shell 6 closely cooperate, and base movement rod 3 and base 4 are fixed together, and by moving of base movement rod 3, promote wireless pinhole cameras 1 and light source 7 moving in tubular shell, the suitable distance that control is taken.
