Description

Portable gasoline instrument

Technical field

This utility model relates to a kind of portable gasoline instrument.

Background technology

Portable gasoline instrument is usually used in afforestation industry, its electronic ignition system is one of them critical system, electronic ignition system mainly includes flywheel, ignition coil, spark plug, Main Function is that the spark plug generation spark driven by high-tension coil by the burning mixture sucked in combustor lights burning mixture, it is allowed to blast release energy, and electronic ignition system is at most suitable ignition angle, send enough ignition energies, the gasoline engine that can allow portable gasoline instrument operates steadily, and improves efficiency.The electronic ignition system commonly used at present includes magneto, lighter, the induction coil being arranged on cylinder, and the permanent magnet being arranged on flywheel, permanent magnet is along with flywheel turns is when each circle meets with the induction coil being fixed on cylinder, the faradic current that will produce faradic current (principle is just as electromotor) and the highest generation of Speed of Reaction Wheels in induction coil is the biggest, the lowest faradic current of rotating speed is the least, make be attached thereto to be placed in the plug ignition that petrol engine combustion is indoor the voltage that this coil-induced Current amplifier becomes several ten thousand volts by circuit.But this electronic ignition system has the disadvantage in that its voltage is directly proportional to rotating speed, when rotating ratio is relatively low, the faradic current of generation is little, and the energy of igniting also ratio is relatively low, wherein time of ignition, and the relation of ignition energy and rotating speed is as shown in Figure 1.And in start-up phase, rotating speed is relatively low, ignition energy can not produce the big spark now needed, and is unfavorable for igniting, causes gasoline engine to be difficult to start, affects user and use.
