Description
Technical field
The present invention relates to a kind of improvement of motor, specifically a kind of piston tubular actuated by cams formula five two-stroke engine that axially liquidates.
Background technique
Motor (Engine) is a kind of the machine that can be converted into mechanical energy of other form, can comprising as internal-combustion engine (petrol engine etc.), external-combustion engine (Stirling engine, steamer etc.) etc.The main structure form of current internal-combustion engine is conventional engine, comprises four-stroke and two-stroke, makes the transform linear motion of piston be rotary motion by connecting rod; Its body is cuboid, and cylinder becomes determinant to arrange, and upper end is provided with cylinder cap, is provided with inlet hole and exhaust port in cylinder cap.Although this motor is widely used, being in operation, it is following not enough also to find: one is that efficiency is low, and petrol engine efficiency is generally 25% ~ 35%, and Efficiency of Diesel Engine is generally 35% ~ 45%; Two is be all reciprocating piston connecting rod, and machine vibration is large, needs balanced controls, and four stroke engine all establishes complicated distribution device, and it is residual that two stroke engine shortcoming is that exhaust has, excessive fuel consumption; No matter three is that four-stroke or two-stroke delivery temperature are all higher, engine power loss about 35% is taken away by the waste gas of discharging, internal-combustion engine is motor most effective in heat engine, but the heat produced after entering the fuel combustion of motor, only have sub-fraction to become useful work, all the other major parts lost due to a variety of causes; Four is four stroke cycle, only has a piston in cylinder, and namely descending air-breathing, up compression, igniting outburst make descent of piston acting, up exhaust, and such four strokes want crankshaft rotating two to enclose, and only do work once; Brace and connecting rod framework, the stroke of each stroke is consistent, changeless, and at expansion stroke end, waste gas starts to discharge, and discharge temperature is high, takes away most heat, accounts for 35% of fuel combustion total amount of heat; Five is that four stroke engine has complicated distribution device.
In order to improve the deficiency existing for current motor, known by retrieving, existing multiple report, two rotary cylinders, first piston and the second piston is comprised as Chinese patent 201310068195.9 discloses " a kind of opposed piston engine ", two rotary cylinders are oppositely installed, and first piston and the second piston are located in two rotary cylinders respectively, and direction is contrary, piston rod stretches out to both sides, is realized the to-and-fro motion of first piston and the second piston by the bent axle drivening rod at two ends; Chinese patent 201220201255.0 discloses " a kind of five stroke three connecting rod variable compression ratio contraposition engines ", adopts single cylinder, three connecting rods, crank mechanism, and bent axle has often circled compression, exhaust, scavenging, air-breathing and compression five strokes; Chinese patent 02828207.8 discloses one and " uses the internal-combustion engine of opposed pistons ", comprises cylindrical shell body, circumferentially arranges column cylinder, two pistons are set in cylinder, and connect power cam outputting power, power cam is double layer construction, improvement be two-stroke structure internal-combustion engine; The deficiency of this " using the internal-combustion engine of opposed pistons " is: because internal-combustion engine is two-stroke structure, piston assembly separately range of movement is fixed, piston can not cross top dead center, acting tail end venting, plenum chamber gas by inlet charge, and scans out cylinder pressing chamber waste gas, newly entering air and waste gas has mixed, there is exhaust residual, fuel efficiency is low, and this is two stroke engine common fault; And power cam used and supporting component double leval jib device, piston rod, piston linkage structure complicated, be not easy to implement; The air-bearing principle that piston adopts reduces friction, and piston end motive bearing and reset bearing mounting structure are cantilever structure, and especially motive bearing needs powerful active force when bearing cylinder fuel outburst, is unfavorable for obtaining beneficial effect; Each cylinder is divided into three chambers by inlet piston, exhaust pition, two ends end cover, three exhaust passages, place's gas-entered passageway one place, seal structure complex, less reliable.
These improve above, although have certain effect in raising engine power, and unreasonable because of structure, and make complex structure, be difficult to obtain and effectively carry high-power ideal effect.At present, there is not yet cylinder for cylindric and circumferentially arrange, opposed pistons is respectively by tubular cam Direct driver, by piston itself control inlet and outlet mouths different time opening and closing, and the report of motor containing backhaul, air-breathing, compression, acting, exhaust five strokes.
