Description
Technical field
The utility model relates to a kind of multi-cylinder two stroke engine.
Background technique
Available engine has two stroke engine and four stroke engine, two stroke engine structure is simple, light, complete once acting only need rotate a circle, but each operation parts insufficient lubrication in crankcase, air inlet, exhaust are disturbed mutually, mutual stirring, the unburned fresh inflammable gas of part emits together along with the waste gas after burning, causes waste; Gas for burning is the mixed gas of machine oil and gasoline, and burning is not thorough, and the exhaust emission pollution of discharge is serious.
Four stroke engine lubrication system is comparatively good, and sustainable service time is longer, and running resistance is less, but completes a power cycle bent axle and need rotate two weeks.
A kind of two-stroke engine with double cylinders disclosed in CN102588100, comprise master cylinder and secondary cylinder, wherein master cylinder has been responsible for detonation and exhaust, secondary cylinder has been responsible for air inlet and compression, secondary cylinder camshaft installs the 3rd gear, master cylinder by time rule chains provide power for secondary cylinder, because this power is through being positioned at the amplification of the second gear on master cylinder to the 3rd gear be positioned on secondary cylinder, therefore the increase corresponding to power of its outputting power; Master cylinder and secondary cylinder synchronization motion, namely crankshaft rotating 360 completes a work cycle.Do not meet two stroke engine working principle.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, and aiming to provide one can separate air inlet and exhaust, and air inlet, exhaust non-interference, do not stir mutually, and thoroughly, energy saving, can reduce toxic emission, significantly improves the multi-cylinder two stroke engine of power in burning.
The implementation of the utility model object is, multi-cylinder two stroke engine, and on crankcase, dress is for cylinder, working cylinder, combuster on working cylinder, and top of combustion chamber has spark plug, valve; Two crank throw one of bent axle connects the air feed piston supplying cylinder by air feed connecting rod, one connects the working piston of working cylinder by work connecting rod, for cylinder head having mixed gas intake duct, suction valve, gas outlet valve; Store gas transmission road to be connected with the valve on working cylinder cylinder cap and for the gas outlet valve in cylinder head, there is exhaust vent working cylinder middle and lower part, and exhaust vent is connected with outlet pipe.
Adopt the utility model, without crankcase air inlet, without the mixed gas of oil gas and machine oil as combustion gas, by for cylinder air feed, make to enter mixed gas mixing in working cylinder fully, burn more thorough; Waste gas is pressed to exhaust vent and discharges by the mixed gas through delivering to working cylinder for cylinder, and inlet and outlet separately, are not stirred mutually, and can significantly reduce unblended mixture and discharge with waste gas; Effect, energy-conservation, reduction of discharging can be significantly improved.

Embodiment
With reference to the accompanying drawings in detail the utility model is described in detail.
On crankcase 20, dress is for cylinder 4, working cylinder 13, and combuster 12 on working cylinder, top of combustion chamber has spark plug 15.Two crank throw one of bent axle 5 connects the working piston 14 supplying 2, one, the air feed piston of cylinder by work connecting rod 18 even working cylinder by air feed connecting rod 3, for cylinder head 10 having mixed gas intake duct 11, gas outlet valve 16; Store gas transmission road 17 to be connected with the valve 8 on working cylinder cylinder cap 9 and gas outlet valve 16, there is exhaust vent 19 working cylinder middle and lower part, and exhaust vent is connected with outlet pipe.
Mixed gas intake duct 11 has mixed gas suction valve 1, mixed gas stores on gas transmission road 17 mixed gas gas outlet valve 16.
The utility model intake process (see Fig. 1), last time, the exploding gas of power cycle pushed the work forward descent of piston to exhaust vent upper end, valve 8 is opened, bent axle drives air feed piston stroking upward, working cylinder 13 is entered by storing gas transmission road for the mixed gas 7 of preparing for working cylinder air inlet in cylinder by mixed gas, working piston 14 in working cylinder comes downwards to lower dead center, valve-closing, and working cylinder intake process terminates.
Compression process (see Fig. 2), working piston 14 in working cylinder is up, mixed gas 7 in working cylinder is compressed into firing chamber, bent axle drives air feed piston 2 descending simultaneously, mixed gas suction valve 1 on mixed gas intake duct is opened, and mixed gas is sucked for cylinder by mixed gas intake duct 11, and air feed descent of piston is to lower dead center, working piston goes upward to top dead center, and working cylinder compression process terminates.
Acting process (see Fig. 3), the plug ignition of top of combustion chamber, compress into the mixed gas detonation of firing chamber, exploding gas pushes the work forward descent of piston acting, and simultaneously bent axle drives air feed piston stroking upward, and gas outlet valve 16 is opened, mixed gas press-in is stored in gas transmission road 17 and stores, for working cylinder air inlet next time is prepared, working piston comes downwards to exhaust vent 19, and working cylinder acting process terminates.
Exhaust process (see Fig. 4), working piston comes downwards to exhaust vent 19, gas of combustion 6 by exhaust vent through emission by exhaust pipe.For the air feed piston stroking upward in cylinder, working piston comes downwards to lower dead center, and exhaust process terminates.
Crankshaft rotating one week, completes a power cycle.
When bent axle 5 has three to turn, middle turns dress for cylinder 4, and turning of both sides fills working cylinder 13, like this, can give the working cylinder air feed of two synchronization igniting for one for cylinder.When bent axle 5 having the turning with the turning of other direction an of direction more, a direction turn dress for cylinder 4, turning of other direction fills multiple working cylinder 13 more, like this, can give the working cylinder air feed of multiple synchronization igniting for one for cylinder.
