Abstract
The utility model relates to a master part structure for a reciprocating internal combustion engine, and solves the problems of the master part structure of the existing reciprocating internal combustion engine. The problems is that the moment of work doing is small; effective power is low, and only is 23% to 25%; fuel is wasted. A valve mechanism, a cylinder and a speed change mechanism are matched and fixed by being connected through bolts. After a plunger, a connecting rod and a crankshaft are connected by being matched, included angles of 5DGR to 20DGR are formed between the center lines of the plunger and the connecting rod, and between the center lines of the plunger and the crankshaft when the plunger lies in an initial position on the upper part of the cylinder. The descent velocity of the plunger can be decreased; the moment of work doing can be enlarged; work angle can be enlarged; effective power can be increased to 38% to 40%.
Description
The utility model belongs to a kind of mechanical structure of reciprocal internal-combustion engine, particularly a kind of main part structure of reciprocating internal combustion engine.
The main part structure of existing reciprocating internal combustion engine is connected by piston, connecting rod and bent axle and forms; Piston is when initial position, and all on same axis, the acting moment is little for the center line of piston, the center line of connecting rod and the center line of bent axle, and useful horsepower is low, only is 23～25%, waste fuel.
The purpose of this utility model is to solve existing existing problem, and the main part structure of the high reciprocating internal combustion engine of a kind of useful horsepower is provided.
The utility model is to realize like this
By bolt, with distribution device, cylinder and gear are fixedly connected; After piston, connecting rod, bent axle are connected, make its piston when the initial position of cylinder upper end, the center line of the center line of piston and connecting rod, bent axle forms the angle of 5 °～20 ° of degree.
Advantage of the present utility model is, because piston is when the initial position of cylinder upper end, the center line of the center line of piston and connecting rod, bent axle forms the angle of 5 °～20 ° of degree, can reduce the rate of descent of piston, the work done moment strengthens, and increases the work done angle, and useful horsepower increases, can reach 38～40%, thereby fuel saving.
Fig. 1 is a structural representation of the present utility model;
Describe in detail below in conjunction with accompanying drawing:
As shown in the figure, by bolt, with distribution device 1, cylinder 3 and gear 6 are fixedly connected, piston 2 is installed in cylinder 3, piston 2 is by an end of bearing pin installing connecting rods 4, and the other end of connecting rod is installed on the coupling shaft of bent axle 5, makes its piston 2 when the initial position of cylinder 3 upper ends, the center line B of the center line A-A of piston and connecting rod, bent axle-B forms the angle of 5 °～20 ° of degree, its best angle is 12 ° 30 °, increases the acting angle, improves the useful horsepower of internal-combustion engine.
