The node part of the v line-changing connecting rod is connected with an auxiliary device which performs a supporting function and guides the line-changing connecting rod to move. A vertical center line of a cylinder is deviated from the circle center of a crankshaft and passes through any position point in front of the circumferential tangential point of 0 to 60 DEG. Under the condition of not changing the continuous circumferential operation of the crankshaft, the internal combustion engine can realize the tangential point explosion on the circumference of the crank, greatly enhance the heat efficiency of the internal combustion engine, and strengthen the power performance. The present invention has obvious fuel saving effect, is suitable for the fields of the existing internal combustion engines, and can use natural gas, alcohol, etc. as fuels.
Description
The invention belongs to the power category technical field of internal combustion engines, specifically a kind of piston type contact-point explosion internal-combustion engine.
At present, in the existing at home internal-combustion piston engine technical field (mainly referring to petrol engine, diesel engine), piston in the cylinder of internal combustion engine is to be linked by a rigid connecting rod and crank, its bursting point is that crank is when running to formed circular arc summit, cylinder firings outburst (actual have advance angle), so power loss is big, the thermal efficiency is low, is about 36% as the petrol engine thermal efficiency, diesel engine is about 48%.
The object of the present invention is to provide and a kind ofly can increase substantially internal combustion engine thermal efficiency, improve power performance, the significant contact-point explosion type internal combustion engine of oil-saving effect.
For achieving the above object, the technological scheme that the present invention takes is: this contact-point explosion type internal combustion engine comprises cylinder, piston, crank, crankshaft, connecting rod, porthole, cooling system, lubrication system and ignition system, it is characterized in that this connecting rod is the modified line connecting rod, it divides connecting rod to link from beginning to end by two joints, combine by pivot pin, one end of this modified line connecting rod is connected with wrist pin, the other end links to each other with crank, the node place of modified line connecting rod and a support, guide the auxiliary device of its motion to link to each other, dividing the joints of connecting rods at two joints is that the node place is provided with the confined planes that two fens connecting rods can be rotated mutually in 0-180 degree scope, the cylinder vertical center line departs from the crankshaft center of circle, and by arbitrary location point of 0-60 degree before the circumference point of contact, promptly breaking out advance angle is the 0-60 degree; The auxiliary device of above-mentioned supporting guide modified line link motion is made up of guide rod, chute, positioning wheel, one end of guide rod links to each other with the node of modified line connecting rod, slide block in the other end and the chute is connected, and chute branch bilateral symmetry is arranged, and the horizontal sextant angle of chute is the 0-35 degree; There are different cambered surfaces, curved surface in the positioning wheel surface, and the length of cambered surface, curved surface is corresponding in proportion with the position of crank circle respective angles, and guide rod remains with the positioning wheel surface by roll sleeve or roller bearing and contacts; Positioning wheel links to each other with crankshaft by axle, gear train.
When crank is made circular movement, the crow flight distance at above-mentioned connecting rod integral two ends is cyclically-varying, the modified line connecting rod is under the effect of auxiliary device, contiguous circumferential running with crank drives steam-cylinder piston and pumps, at cylinder compresses, exhaust phase, modified line connecting rod two ends crow flight distance shortens, promptly be the modified line state, make crank cross the circumference dot location smoothly, guarantee the piston arrives top dead center; In cylinder suction, outburst stage, when crank runs to the position of 0-60 degree before the circumference point of contact, promptly breaking out advance angle is the 0-60 degree, modified line connecting rod linear state, both guaranteed the efficient transfer of cylinder power, also make simultaneously the modified line connecting rod when outburst, be in stable linear state, with the efficient transfer of realizable force.
By the contact-point explosion type internal combustion engine that such scheme provides, the unique design of its modified line connecting rod and auxiliary device thereof makes crank cross the circumference dot location smoothly at cylinder compression, exhaust phase, guarantees the piston arrives top dead center; In cylinder suction, outburst stage, accurately break out when making crank run to before the circumference point of contact 0-60 degree (promptly breaking out advance angle) position, realize the efficient transfer of cylinder power, just cylinder explosive force is fully utilized at this place, also makes the modified line connecting rod be in stable linear state when cylinder breaks out simultaneously.In addition, the setting of outburst advance angle can make the corresponding increase of piston stroke of cylinder, and the design of the minimum cylinder volume of this countercylinder is favourable.Just be based on the rationality of above-mentioned design, internal combustion engine thermal efficiency is greatly enhanced, power performance improves, and reaches that power is big, power is strong and the low purpose of oil consumption.Because thermal efficiency height so can use natural gas, alcohol etc. to do fuel, has enlarged the accommodation of internal-combustion engine to fuel.
