Abstract
A novel four-stroke energy-saving engine with an elongated connecting rod is provided, wherein a crankshaft connecting rod mechanism is composed of an engine cylinder, a piston, a connecting rod, a crankshaft eccentric center pitch and a crankshaft, the connecting rods with same size and type are lengthened according to the size of engines, and the lengthened size is within 0.5cm-2cm. The crankshaft can be arranged on the left side or the right side, which is deviated from the center line of the cylinder, and the eccentric distance is appropriately arranged according to different types. Compared with a four-stroke engine with same discharge capability, the novel four-stroke energy-saving engine saves 15-18% fuel, and has the advantages of high work efficiency and large output power.
Description
Technical field
The utility model belongs to technical field of engines, relates in particular to a kind of novel four-journey energy-saving engine of connecting rod lengthening.
Background technique
Present four-stroke engine of the prior art, the position of the rotation centerline of its bent axle, it is the compression stroke of firing time, this makes the initial point of the top dead center of its compression stroke for the outburst stroke, at this moment because of the outburst of the fuel combustion in the cylinder, its thermal expansion force is a peak, but engine piston at this moment, connecting rod, the crank of bent axle and the rotating center of bent axle are all on same vertical line, though the highest swelling pressure are arranged, but because of piston, connecting rod, the crank of bent axle and crankshaft rotating center are all on same vertical line and can not form moment to the rotating center of bent axle, therefore the highest formed swelling pressure can not work done or work done seldom, besides the friction load that when moving up and down, produces of piston and have a kind of bent axle partially after the not high situation of compression ratio that causes, because this structural imperfection of above four-stroke engine, make its efficient lower, and wasted some capacity for works.Therefore the mechanical efficiency of existing four-stroke engine also is not too desirable.
The model utility content
The purpose of this utility model is the deficiency that overcomes existing four-stroke engine, provides that a kind of efficient is higher, fuel-economizing, output power is big and the novel four-journey energy-saving engine of the connecting rod lengthening of bent axle biasing.
The novel four-journey energy-saving engine of connecting rod lengthening described in the utility model, its structure are to improve to form on the basis of existing four-stroke engine, mainly comprise cylinder, piston, connecting rod, bent axle.Compressing inflammable in the cylinder is burnt the gaseous combustion outburst, produce power, promote piston and produce oscillating rectilinear motion, change the mechanism that rotatablely moves into by connecting bar and crankshaft, it is that the size of lengthening is by each the numerical value length between the 0.5cm to 2cm with connecting rod large, medium and small connecting rod lengthening corresponding size according to motor on original basis.Simultaneously the position of bent axle is provided with the left side or the right side of departing from cylinder centerline, offset or dish is 1-50cm, and the position of bent axle is arranged on the distance that departs from the cylinder centerline biasing size according to motor, and miniature motor offset or dish is from 1cm to 9cm.The offset or dish of medium duty engine is from each the numerical value length between the 11cm to 20cm.The offset or dish of big-block engine is from each the numerical value length between the 21cm to 50cm.
Adopt the effect of the technical program to be: can improve engine operation efficient and increase output power, with the fuel-economizing of similar discharge capacity type.
Description of drawings
Fig. 1 is the novel four-journey energy-saving engine structural representation of connecting rod lengthening;
Among the figure: 1-cylinder, 2-piston, 3-connecting rod, 4-bent axle Off center distance, 5-bent axle.
Embodiment
The novel four-journey energy-saving engine of connecting rod lengthening described in the utility model, the contrast accompanying drawing elaborates to specific embodiment: its structure is to improve to form on the basis of existing four-stroke engine, comprise cylinder 1, piston 2, connecting rod 3, bent axle 5, bent axle 5, connecting rod 3, the improved structure of piston 2 mechanisms are: press the large, medium and small of motor, at the connecting rod 3 sizes lengthening of the similar type of identical size, the size of lengthening is by each the numerical value length between the 0.5cm to 2cm; With the position of bent axle 5, be arranged on the left side or the right side of departing from cylinder centerline simultaneously, bent axle 5 departs from the bent axle Off center apart from 4, and according to the size of motor, the bent axle 5 of tiny engine departs from that the offset or dish of bent axle Off center apart from 4 is 1,3,4cm; The bent axle 5 of mini engine depart from the bent axle Off center apart from be 6,7,8cm, the bent axle 5 of medium duty engine departs from that the offset or dish of bent axle Off center apart from 4 is 11,12,13,14,15,16,17,18,19, each numerical value length of 20cm, the bent axle 5 of big-block engine departs from that the offset or dish of bent axle Off center apart from 4 is 21,22,24,26,28,30,32,34,36,38,40,42,44,46,48, each the numerical value length between the 50cm, and the corresponding lengthening of length of connecting rod (3) adapts with it.
Because adopting technique scheme improves the structure of motor, make the rotation centerline and the cylinder center of engine crankshaft 5 depart from a left side or right certain distance setting, thereby changed the friction angle of engine piston when moving up and down, reduced load, connecting rod 3 lengthenings, changed the firing time of motor, make it postpone outburst, break out moment, piston, connecting rod, the rotating center of active force on the crankshaft crank and bent axle 5 is not on same vertical line, the swelling pressure that just produced during the burning outburst can form certain moment to the rotating center of bent axle, add that minimum cylinder volume changes in the firing chamber, thereby improved the efficient of motor, increased capacity for work, in addition than carrying out proper functioning under the high contractive condition of the compression ratio of available engine, compare with the four-stroke engine of same displacement, has the fuel oil of saving 15-18%, high working efficiency, the advantage that output power is big.
