A signal sensor is arranged at any output terminal of the gasoline engine with a pulse electric signal, the signal sensor is connected with a rotating speed display instrument by a signal conductor. The utility model can perform real-time online display about the current rotating speed and the change of the engine, the user and servicing personnel can adjust correctly and duly the rotating speed and load of the engine according to the dynamic data displayed by the rotating speed display instrument and the technical parameters specified on the gasoline engine. The utility model also facilitates to help the user and servicing personnel to examine and eliminate the malfunction, and then to adjust correctly the idle speed and the highest no-load speed of the engine so as to reduce the oil consumption of the gasoline engine to prolong the period of usage of the gasoline engine.
Description
Technical field
The utility model relates to petrolic improvement technology, particularly relates to a kind of Small Universal petrol engine with the engine speed Presentation Function.
Background technique
In the prior art, professional tachometer can carry out the rotating speed adjustment to motor, but because cost is higher, is difficult to use on common Small Universal petrol engine.And in use do not have the following disadvantages: 1) be not easy to the current rotating speed of motor and rotation speed change and adjust accordingly with the general-purpose petrol engine of rotating speed Presentation Function; 2) can not the intuitive judgment engine operating condition whether normal; 3) be not easy to assisted diagnosis and get rid of engine failure; Correct idling and the maximum no-load speed of adjusting motor when 4) being not easy to O﹠M.The user is when using petrol engine, if can not correctly petrol engine be adjusted to suitable rotating speed state, will cause the higher or rotating speed of petrol engine oil consumption to fail to be in the scope that technical parameter sets, thereby make motor when idling, not reach specified value during flame-out or load speed and the machine breakdown that causes.
Summary of the invention
At the deficiency that prior art exists, a kind of Small Universal petrol engine that the purpose of this utility model provides with the engine speed Presentation Function.
The purpose of this utility model is achieved in that the Small Universal petrol engine of band engine speed Presentation Function, signalization pick-up transducers on the arbitrary device that can produce pulse electrical signal of petrol engine, the signals collecting sensor connects the rotating speed Displaying Meter by signal conductor.
The generation device of described petrol engine pulse electrical signal can be spark coil, lighting loop, spark plug, flywheel or charge coil; These devices produce the variation of certain magnetoelectricity when petrol engine is worked, thus the variation of display frequency.
When external force makes engine running, the flywheel rotation, the mixed gas that Carburetor produced enters that cylinder head promotes piston through the spark ignitor mixture combustion, connecting rod is reciprocating and promotes crankshaft rotating, gas of combustion is discharged through silencing apparatus, the sampled signal of spark coil output is delivered to signal emitter, through signal conductor signal is delivered to the dynamic change that the rotating speed Displaying Meter shows petrol engine rotating speed and rotating speed again.
Compared to existing technology, the utlity model has following advantage:
1, can show current rotating speed and the rotation speed change of petrol engine by real-time online;
2, user and maintenance man can in conjunction with the technical parameter that petrol engine is demarcated, can correctly, in time adjust petrolic rotating speed, load according to the dynamic data of rotating speed Displaying Meter demonstration;
3, help helping user and maintenance man diagnosis, eliminating engine failure, correctly adjust the idling and the maximum no-load speed of motor, reduce the petrol engine oil consumption, prolong petrolic working life.
4, the signal emitter that the utility model adopted, rotating speed Displaying Meter, advantage such as have that volume is little, cost is low, signals collecting mode flexibility and reliability, complete machine versatility and interchangeability are strong, and do not influence the complete machine appearance and the general assembly condition of former small utility gasoline engine.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The Small Universal petrol engine of the band engine speed Presentation Function that the utility model provides, on the basis that does not change existing general-purpose petrol engine structure, utilize general-purpose petrol engine self can produce the position of electrical pulsing signal, there are arbitrary parts of pulse electrical signal to obtain signal from petrolic spark coil, lighting loop, spark plug, flywheel or charge coil etc., realize that the real-time online of petrol engine rotating speed shows; Need not increase other wiring circle and can gather electrical pulsing signal.
Embodiment 1: referring to Fig. 1～Fig. 5, the small-sized single cylinder general-purpose petrol engine of band engine speed Presentation Function, it comprises casing 1, bent axle 2, connecting rod 3, piston 4, cylinder head 5, empty filter 6, flywheel 11, Carburetor 12, spark plug 13, silencing apparatus 14, spark coil 10, pulse electrical signal end signalization sensor 9 at ignition coil for gasoline engine 10, the pulse electrical signal entering signal sensor 9 of output, the signal conductor 8 that signal emitter 9 is drawn directly links to each other with rotating speed Displaying Meter 7.Sensor 9 is fixed on by bolt 15 on arbitrary parts of general-purpose petrol engine, and Displaying Meter 7 is fixed on arbitrary parts of general-purpose petrol engine by dunnage 16, bolt 15.Displaying Meter adopts prior art to get final product.
Its working principle is: when external force makes engine running, flywheel 11 rotations of band magnet steel, the mixed gas that Carburetor 12 produced enters cylinder head 5 and lights mixture combustion and promote piston 4, connecting rod 3 reciprocating and promotion crankshaft rotating through spark plug 13, gas of combustion is discharged through silencing apparatus 14, the sampled signal of spark coil 10 outputs is delivered to signal emitter 9, signal emitter 9 is transferred to the dynamic change that rotating speed Displaying Meter 7 shows petrol engine rotating speed and rotating speed with signal by signal conductor 8 after circuit shaping, digital translation.When the petrol engine rotating speed changed, the rotating speed of flywheel 11 changed, and then the pulse electrical signal that produced of spark coil 10 changes, and Displaying Meter 7 shows the corresponding dynamic rotating speed immediately.
The utility model is particularly suited for single cylinder Small Universal petrol engine, also can be applicable to other universal motor.From lighting loop, spark plug, flywheel or charge coil acquisition pulse electrical signal, the structural principle that the real-time online of realization petrol engine rotating speed shows is identical with embodiment 1, does not enumerate one by one at this.
