Abstract
The utility model relates to the field of engine technology, a engine cylinder monitoring devices is disclosed, include: microprocessor (1), camshaft position sensor (2), bent axle position sensor (3), engine temperature sensor (4), wireless communication module (5), pilot lamp (6), memory (7), wherein, microprocessor with camshaft position sensor (2), bent axle position sensor (3), engine temperature sensor (4), wireless communication module (5), pilot lamp (6), memory (7) are connected, camshaft position sensor (2) set up the end at the car camshaft, crankshaft position sensor (3) set up in the car distributor. The utility model discloses can judge accurately whether every cylinder in the engine breaks down, and monitoring results is accurate, use extensively, it is with low costs.
Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of cylinder monitoring device.
Background technique
At present, by detecting cylinder Key Performance Indicator (as cylinder pressure, speed of crankshaft, wear intensity etc.), automobile engine cylinder monitoring device mainly judges whether cylinder breaks down.But motor car engine has multiple cylinder, this kind of cylinder monitoring device need be installed same sensor and could monitor each cylinder in each cylinder, adds cost undoubtedly.Meanwhile, automobile engine cylinder Key Performance Indicator can not reflect the service behaviour of cylinder comprehensively, cannot detect whether automobile engine cylinder breaks down completely.
Model utility content
The utility model provides a kind of cylinder monitoring device, and need install same sensor in solution prior art in each cylinder could monitor each cylinder, adds the technical problem of cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cylinder monitoring device, comprise: microprocessor 1, CMPS Camshaft Position Sensor 2, crankshaft position sensor 3, engine temperature sensing unit 4, wireless communication module 5, tutorial light 6, storage 7, wherein, described microprocessor is connected with described CMPS Camshaft Position Sensor 2, crankshaft position sensor 3, engine temperature sensing unit 4, wireless communication module 5, tutorial light 6, storage 7, described CMPS Camshaft Position Sensor 2 is arranged on vehicle cam the tip of the axis, described crankshaft position sensor 3 be arranged on automobile distributor controlled in
The beneficial effects of the utility model are:
Which cylinder spark acting is determined according to the camshaft-position signal that CMPS Camshaft Position Sensor 2 detects, engine speed when this cylinder does work is calculated according to the crankshaft-position signal of crankshaft position sensor 3 detection, by microprocessor 1 analyze the amplitude of the engine speed change when the acting of work cycle intrinsic motivation each cylinder whether consistent or judge present engine rotating speed whether with the difference of historical data that stores in storage, thus judge whether in-engine each cylinder breaks down exactly, monitoring result is accurate, be widely used, cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, also can obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, for a kind of cylinder monitoring device, comprise: microprocessor 1, CMPS Camshaft Position Sensor 2, crankshaft position sensor 3, engine temperature sensing unit 4, wireless communication module 5, tutorial light 6, storage 7, wherein, described microprocessor is connected with described CMPS Camshaft Position Sensor 2, crankshaft position sensor 3, engine temperature sensing unit 4, wireless communication module 5, tutorial light 6, storage 7, described CMPS Camshaft Position Sensor 2 is arranged on vehicle cam the tip of the axis, described crankshaft position sensor 3 be arranged on automobile distributor controlled in.
Wherein, can also comprise liquid crystal display panel, described liquid crystal display panel is located on vehicle console.
Whether the amplitude that microprocessor 1 compares the engine speed change when work cycle intrinsic motivation each cylinder acting is consistent.If the amplitude that when amplitude of engine speed change during some cylinder actings in a work cycle and other cylinder do work, engine speed changes is inconsistent or differ greatly, then microprocessor 1 judges that this cylinder exists fault, and sends a signal to remote control center by wireless communication module 5 or send to the liquid crystal display panel on vehicle console.
In addition, historical data can also be preserved by the utility model, in follow-up judgement, engine speed during each cylinder acting and its account of the history can be compared, accelerate the judgement speed of malfunction monitoring.Meanwhile, also download monitoring facilities and data by wireless communication module 5 from remote control center, to change mode or the flow process of cylinder monitoring flexibly.
The beneficial effects of the utility model are:
Which cylinder spark acting is determined according to the camshaft-position signal that CMPS Camshaft Position Sensor 2 detects, engine speed when this cylinder does work is calculated according to the crankshaft-position signal of crankshaft position sensor 3 detection, by microprocessor 1 analyze the amplitude of the engine speed change when the acting of work cycle intrinsic motivation each cylinder whether consistent or judge present engine rotating speed whether with the difference of historical data that stores in storage, thus judge whether in-engine each cylinder breaks down exactly, monitoring result is accurate, be widely used, cost is low.
Be understandable that, the system architecture shown in figure does not form the restriction to system, can comprise the equipment more more or less than diagram, or combine some equipment, or different deployed with devices.
Above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
