Description
Technical field
The utility model relates to piston internal-combustion machine technology, is specifically related to a kind of motor with offset crankshaft.
Background technique
Motor is the important component part of orthodox car, and internal-combustion piston engine is a kind of common motor car engine.Motor generally includes cylinder body, and is arranged on piston, connecting rod and the bent axle in cylinder body.Also be provided with firing chamber in cylinder body, fuel, in firing chamber combustion, promotes piston thus and moves back and forth.The two ends of connecting rod connect piston and bent axle respectively, and connecting rod and bent axle form connecting rod, for the to-and-fro motion of piston being transformed into the rotary motion of bent axle.
Part motor adopts offset crankshaft, the lateral force of piston is acted on when effectively can reduce expansion stroke, and then reduce piston to the lateral pressure of cylinder side wall, thus the energy consumed because of friction between piston to cylinder side wall also can correspondingly be reduced, not only increase the thermal efficiency of motor, the working life of cylinder body and piston can also be extended; Meanwhile, due to the biased setting of bent axle, cause piston stroke to strengthen, piston working application time extends, and is conducive to the Thorough combustion of fuel, can obtains more useful work under same combustion condition, thus improves fuel availability.
Offset crankshaft is generally arranged in cylinder body by bearing support, bearing support is made up of HT250 type cast iron, and the castiron part surface of HT250 type is coarse, needs the attachment face contacted with cylinder body of bearing support to cut into plane, due to needs cutting operation, so the cost of bearing support is high.Secondly, the excessive backward stroke of the piston resistance that easily causes of the offset of offset crankshaft is excessive, and the too small then fuel availability of offset is low.
Model utility content
The utility model solves the existing technical problem that motor cost is high, fuel availability is low with offset crankshaft.
For solving the problems of the technologies described above, the utility model provides following technological scheme:
A kind of motor with offset crankshaft, comprise the cylinder body with multiple cylindrical cylinder holes and the piston, connecting rod and the offset crankshaft that are arranged in cylinder body, wherein, piston is connected by connecting rod with offset crankshaft, offset crankshaft is arranged in cylinder body by bearing support, in multiple cylindrical cylinder holes, the center line of each cylindrical cylinder holes is parallel to each other, center line parallel to each other forms the first plane, the axis being parallel of offset crankshaft is in the first plane, and the axis of offset crankshaft is 13mm to 15mm to the distance of the first plane; Bearing support is made up of F0202J sintered copper steel.
Preferably, the axis of offset crankshaft is 14mm to the distance of the first plane.
The utility model belongs to the object utilizing offset crankshaft to reach reduction friction, reduction fuel consume.And when offset is more than 15mm or lower than 13mm, crankshaft eccentric structure does not have a significant effect for the reduction of piston skirt and cylinder side wall middle pressure, therefore offset is set to 13mm to 15mm.Such offset crankshaft structure is more conducive to strengthening intake stroke and working stroke, makes air inlet more abundant, and expand more thorough, fuel availability is high; Make compression stroke shorten simultaneously, be more conducive to the insulation effect of compression process.The bearing support be made up of F0202J sintered copper steel does not need to cut attachment face before use, decreases processing cost.Therefore, the existing technical problem that motor cost is high, fuel availability is low with offset crankshaft is solved.
