Description
Technical field
The present invention relates to digital igniter technical field more particularly to a kind of digital points for mini four-stroke engine
The working method of firearm.
Background technique
Lubricating oil can play the effects of lubrication, cleaning, cooling, sealing, anti-attrition, antirust, corrosion protection, engine work to engine
When making, if some friction parts cannot get lubrication appropriate, dry friction, the heat that dry friction generates in a short time will be generated
Amount is enough to make metal molten, causes parts damage even stuck, it is therefore necessary to give good profit to the friction part of engine
It is sliding.On the one hand heat that fuel generates after burning in engine is completed by cooling system, on the other hand by lubricating oil from cylinder,
The surfaces such as piston, crankshaft distribute after siphoning away heat into oil sump.Engine can generate many dirts during the work time, lubrication
Oil can complete dirt cleaning work in cyclic process, and avoiding dirt from being bonded in surface of the work causes engine that cannot normally transport
Turn.Lubricating oil forms oil film in the gap of each parts, ensure that the leakproofness of cylinder.In engine working process, fuel combustion
Sour gas can be generated after burning, lubricating oil can directly connect in the oil film that surface of the work is formed to avoid parts and water, sour gas
Touching is prevented to corrode and be corroded.In addition, lubricating oil can also eliminate the shock loading that each parts are subject to, keep engine steady
Work, prevents metal from directly contacting, and reduces abrasion.
It how to be the key that on schedule that can engine work normally to mini four-stroke engine addition lubricating oil, it is some
The manufacturer of engine can indicate machine operation on product description and add up after reaching total time n hours to add lubrication to machine
The operating instruction of oil, but how user remembers that the accumulative total time of machine operation is a problem.Particularly with applying in Gardener
For mini four-stroke engine on the small domestic appliances such as tool, generator, water pump, engine is generally spaced operation, and every
The length of time of secondary operation is different, in this way, user unlikely clearly remembers the accumulative total time of machine operation.
Some manufacturers edges show the traditional technology of transparency window with oiling position is opened up on crankcase, but can be because inevitable
Pollution effect observing effect, requirement cannot be met well.Furthermore by mini four-stroke engine volume and shape
Limitation, some mini four-stroke engines are not suitable for adding that lubricant level shows transparency window or to add position undesirable.Therefore,
How to remind in a well defined manner user to mini four-stroke engine addition lubricating oil be the industry important technology project it
One.
Summary of the invention
In order to solve above-mentioned shortcoming and defect existing in the prior art, the present invention provides it is a kind of can be in use
