Abstract
The utility model relates to an internal-combustion engine connecting bar mechanism, which is characterized in that the whole connecting mechanism comprises a main connecting bar, an elbow connecting bar, a swing support and a driving bar. The P end of the main connecting bar is connected with a piston assembly and the D end thereof is connected with the elbow connecting bar. The L end of the elbow connecting bar is connected with the driving bar. The swing support is fixed on an air cylinder body. The R end of the driving bar is connected with a winch. The O end of the winch is the rotating center of the winch. The utility model improves the effective thermal efficiency of a diesel engine by more than 60 percent and improves the effective thermal efficiency of a gasoline engine by more than 50 percent by optimizing a plurality of structural parameters and maintaining other input conditions.
Description
Technical field
The utility model relates to a kind of internal-combustion engine, particularly relates to the linkage mechanism of internal-combustion engine.
Background technique
The linkage mechanism that Modern Internal-Combustion Engine extensively adopts all is the lineal shape connecting rod, the deadly defect of lineal shape connecting rod is: when cylinder pressure reaches peak phase, because of angle intrinsic between crank and its connecting rod relation, cause connecting rod to act on the crank tangential component driving efficient very little, thermal power very low; And when the angle between crank and connecting rod relation when helping direction that thermal power drives efficiengy-increasing and change, cylinder pressure begun to be exponential relationship and descended rapidly, seemed that reserve strength is weak.
The model utility content
The utility model has designed a kind of linkage mechanism of internal-combustion engine, and the problem of its solution is exactly the deadly defect that will as far as possible overcome conventional linkage mechanism, the obstacle of removing the lifting of obstruction internal combustion engine thermal efficiency.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of linkage mechanism of internal-combustion engine is characterized in that: whole linkage mechanism comprises master connecting rod, elbow connecting rod, gantry pillars and driveshaft, and the P end of described master connecting rod is connected with piston set, and the D end of described master connecting rod joins with the elbow connecting rod; The R end of described driveshaft joins with crank.
The linkage mechanism of this internal-combustion engine has following beneficial effect: preferred by to several structural parameters, under the situation that other initial conditions remains unchanged, can make the effective thermal efficiency of diesel engine reach more than 60%, the effective thermal efficiency of petrol engine reaches more than 50%.
Description of drawings
Fig. 1 is the structural representation of the linkage mechanism of the utility model internal-combustion engine.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further:
A kind of linkage mechanism of internal-combustion engine, whole linkage mechanism is made of master connecting rod 2, elbow connecting rod 3 and gantry pillars 4 thereof and driveshaft 5, and the P end of master connecting rod 2 joins with piston set 1, the D end joins with elbow connecting rod 3; The L end of elbow connecting rod 3 joins with driveshaft 5, and gantry pillars 4 is fixed on the cylinder block 7; The R end of driveshaft 5 joins with crank 6, and the O end of crank 6 is the rotating center of crank.
Gantry pillars 4 is positioned at the plane of movement of crank-link mechanism, and is positioned at along the crank sense of rotation, departs from the coordinate points of cylinder centerline certain distance.
The gantry pillars Q of elbow connecting rod DL is positioned at the plane of movement of crank-link mechanism, and is positioned at along the crank sense of rotation, departs from the coordinate points of cylinder centerline certain distance.
