Abstract

The invention relates to a two-stroke single-combustion multi-piston internal combustion engine, namely an internal combustion engine with a combustion chamber having a plurality of pistons working simultaneously to output power, which comprises a valve mechanism, an air inlet pipe and an exhaust pipe, and is characterized in that: one end of the air inlet and outlet pipe is arranged on the cylinder wall near the lower dead point of the piston cylinder; the piston moves in the cylinder to open and close the air passage. The internal combustion engine has the advantages of low manufacturing cost, small pollution discharge, low oil consumption and the like.

Description

A kind of two-stroke single combustion multi-piston type internal-combustion engine

The present invention relates to a kind of two-stroke single combustion multi-piston type internal-combustion engine, be applicable in the dynamical systems such as motorcycle, automobile.

There is the internal-combustion engine of a plurality of pistons work done simultaneously outputting power a firing chamber of research and design at present, there is the multi-cylinder of patent No. ZL9920633.9 design to fill in the co-combustion split shaft internal-combustion engine altogether, a kind of multiple-piston internal combustion engine of the patent No. 2101247817.2 designs, a kind of single combustion multi-piston internal-combustion engine of number of patent application 031287441 design, this internal-combustion engine is manufactured experimently out the single combustion multi-piston type internal-combustion engine that can work on September 24th, 2004 by the inventor in Yibin, Sichuan at present.More than the distribution device of three kinds of internal-combustion engines, all be to adopt air gate distribution device, the inlet and outlet door is arranged on the central authorities of firing chamber, between each lively atmosphere cylinder top dead center.

The objective of the invention is, by above I. C engine distribution mechanism is improved, it is simple to design a kind of manufacturing, and cost is low, and oil consumption is low, and pollutant emission is little, two kinds of journey internal-combustion engines that the body stationarity is good.

The objective of the invention is,, set up near each piston-cylinder lower dead center that intake and exhaust port realizes by cancellation single combustion multi-piston type internal-combustion engine valve distribution mechanism.

A kind of two-stroke single combustion multi-piston type internal-combustion engine comprises distribution device, and suction tude, outlet pipe are arranged, and is characterised in that: gas port one end of air inlet and exhaust piper is near the cylinder wall the piston-cylinder lower dead center, and piston moves up and down in cylinder, the open and close gas port.

Aforesaid internal-combustion engine is characterised in that: suction tude and crankcase UNICOM, crankcase and crankcase have tracheae UNICOM.

Described internal-combustion engine is characterised in that: the suction tude front end has gas pressurized device.

Aforesaid internal-combustion engine is characterised in that: have many exhaust fork tracheaes to be connected in parallel, have many suction tude to be connected in parallel, every intake and exhaust fork tracheae and a firing chamber cylinder body UNICOM.

The beneficial effect of comparing with background technique:

One, solved IC engine gas distribution device technical barrier has been set, made internal-combustion engine have applicability.

Two, reduce complicated air gate distribution device, cut down the consumption of energy and manufacture cost.

Three, intake and exhaust port helps intake and exhaust not at same position and keep at a certain distance away, and reduces fuel emission.

Four, make part waste gas, do not needing to set up exhaust gas circulating device, participate in secondary combustion, reduce pollutant emission.

Be described further below in conjunction with accompanying drawing:

Accompanying drawing 1: a kind of structural representation of two-stroke one cylinder double stopper type internal-combustion engine;

Fig. 2: a kind of intake duct and crankcase UNICOM, the Structure of Internal-Combustion Engine schematic representation of crankcase and crankcase UNICOM;

Fig. 3: a cylinder double stopper type Structure of Internal-Combustion Engine schematic representation of a plurality of firing chambers.

Among the figure: 1, air flue; 2, gas port; 3, tracheae; 4, piston-cylinder; 5, spark plug formula oil sprayer; 6, piston; 7, UNICOM's tracheae; 8, gear drive; 9, firing chamber

Embodiment 1 Fig. 1, a kind of two-stroke one cylinder double stopper type internal-combustion engine

Among the figure, intake duct 1, air outlet flue 1 is separately positioned on cylinder 4 two ends, and gas port is positioned near the casing wall of piston lower dead center.Spark plug formula oil sprayer is arranged between the two-piston top dead center.

Working principle: piston A, B, to top dead center, porting is under the sealing of piston from lower dead center, begin to close, when two gas ports were closed fully, A, B piston began pressurized gas, when A, B piston reach top dead center a flash, compressing ignition engine internal-combustion engine in this way, if the oil sprayer commencement of fuel injection is ignition internal combustion engine, spark plug begins igniting, fuel combustion promotes piston and moves to lower dead center, and internal combustion enters the work done stage; When exhaust pition reaches relief opening, air outlet flue is opened, and fuel combustion finishes, and waste gas is discharged by tracheae from air flue; The A piston motion is to suction port, and intake duct is opened, and the gas of high pressure enters in the cylinder from suction tude, and A, B piston reach lower dead center, and internal-combustion engine continues inlet and outlet, and piston to top dead center, continues the above motion of circulation by lower dead center.

If the intake duct of internal-combustion engine is connected with crankcase, rely on crankcase to produce air pressure input gas, can not set up gas pressurized device at the air inlet pipe end; If intake duct is not communicated with crankcase, just must set up gas pressurized device, in order to air inlet at the air inlet pipe end; The supercharging device purpose is to produce certain pressure gas, is not described further here; If a cylinder that relies on crankcase to produce air pressure is filled in internal-combustion engine more, have only a suction port, a pipeline can be set, two crankcase UNICOMs.

Other firing chamber has three, and its distribution principle is identical with the two plugs of a cylinder with the upper piston internal-combustion engines of work done outputting power simultaneously, the inlet and outlet road, be provided with on each piston-cylinder, by piston in cylinder, move unlatching, close air flue, just be not described further here.
