Abstract
The utility model relates to an operation control manner of an air cooling generator set and particularly discloses a changeable ignition device of the air cooling generator set. The changeable ignition device of the air cooling generator set comprises a correct timing sensor and a sparking plug, wherein the correct timing sensor is opposite to an outer circle face of a flywheel of the air cooling generator set and used for detecting the gap on the flywheel to form pulse signals, and the sparking plug is capable of controlling an engine to ignite. The correct timing sensor is in electric connection with the sparking plug through an electronic control unit. Correct timing pulses are formed through monitoring of rotating speeds of the air cooling generator set by the correct timing sensor and sent to the electronic control unit to be processed. The sparking plug is controlled to ignite according to timing advance output signals of ignition correct timing. Different ignition angles are formed under different rotating speeds, and smooth starting of early-stage power and the maximum operating power of back-stage power are finally achieved.
Description
Technical field
The utility model relates to the operation control method of air-cooled generator set, is specifically related to a kind of variable ignition mechanism of air-cooled generator set.
Background technique
Air-cooled generator set in the market all is to adopt the fixed ignition angle, and in order to satisfy pneumatic and peak output, the angle of igniting is when starting and between after starting, the angle of artificial selection one relative equilibrium is with startup and the power that guarantees generator set as far as possible.
Yet, air-cooled generator set in real work, when it starts with start after optimum ignition angle different, if all adopt identical fixed ignition angle, can not control the maximum running power after this generator set starts effectively.
Summary of the invention
At above-mentioned deficiency of the prior art, the utility model aims to provide a kind of variable ignition mechanism of air-cooled generator set, under the prerequisite that convenient air-cooled generator set power starts smoothly, the maximum that can control effectively after this air-cooled generator set starts operates power.
To achieve these goals, the technical solution of the utility model: a kind of variable ignition mechanism of air-cooled generator set, it comprise the flywheel periphery that is right against air-cooled generator set and for detection of the breach on this flywheel to form the timing sensor of pulse signal, and the spark plug of control engine ignition, described timing sensor is electrically connected with described spark plug control by an ECU (Electrical Control Unit).
Further concrete, described ECU (Electrical Control Unit) is ECU; Have USB interface or RS232/485 interface on the described ECU (Electrical Control Unit), described timing sensor communicates to connect by this interface and ECU (Electrical Control Unit); Described ECU (Electrical Control Unit) is electrically connected by a spark coil and spark plug; Described timing sensor is Hall transducer.
Generator set rotating speed when starting is low excessively, and timing sensor is transferred to ECU (Electrical Control Unit) with pulse signal after detecting ignition timing immediately, and the rotating speed that ECU (Electrical Control Unit) is current according to the frequency computation part of current demand signal, and the signal time by receiving are lighted a fire.When just beginning to start, rotating speed is low excessively, and per minute has only 50-200 to change, and ECU does not postpone plug ignition, and after startup was finished, generating unit speed was brought up to 3000 rev/mins, and igniting need shift to an earlier date certain angle.After ECU (Electrical Control Unit) is calculated rotating speed by the frequency meter of current pulse signal, and according to the advancement amount of ignition timing, output signal to the spark coil energy, spark coil is transferred to spark plug by lead and lights a fire.
The beneficial effects of the utility model: by the rotation speed monitoring formation timing pulse of timing sensor to air-cooled generator set, and reach ECU (Electrical Control Unit) and handle, advancement amount output signal control spark plug according to ignition timing is lighted a fire, form different ignition angles at different rotating speeds, the final smooth startup of power in early stage and the maximum running power of later stage power realized.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
