Abstract

The utility model relates to a cylinder with six scavenge trunks for a motorcycle engine. The utility model is composed of a main scavenge trunk, an auxiliary scavenge trunk, a main flow guiding rib, an exhaust passage, a guiding section, an upper flange disc, a lower flange disc, a heat sink, a bolt hole, an auxiliary guiding rib and a cylinder bore. The utility model is characterized in that the utility model is additionally provided with an auxiliary guiding rib in an auxiliary scavenge trunk of a cylinder of the prior art. One original auxiliary scavenge trunk is changed into two auxiliary scavenge trunks, so the cylinder is provided with six scavenge trunks. Therefore, fresh gas is distributed uniformly, the power and the torsion of an engine is obviously enhanced, and the specific fuel consumption is reduced. The utility model is a latest generation of cylinder for two-stroke engine of a motorcycle.

Description

The six scavenging air belt cylinder block that motorcycle engine is used
The utility model relates to the six scavenging air belt cylinder block that motorcycle engine is used.
In the prior art, the cylinder block that motorcycle engine is used is three, four or five scavenging air belts, and its shortcoming is the skewness of gas in cylinder block, has exhaust zone, thereby causes power, torque and the specific fuel consumption of motor all undesirable.
The purpose of this utility model is to provide a kind of cylinder block of six scavenging air belts, and its advantage is that gas is very even in the inner distribution of cylinder block, thereby improves power, torque and the reduction specific fuel consumption of motorcycle engine.
Embodiment of the present utility model is as follows: it is made of main scavenging air belt, secondary scavenging air belt, major flow muscle, secondary guide rib, air outlet flue, guide section, upper flange plate, lower flange, radiating fin, bolt hole and cylinder diameter.Described main scavenging air belt has 4, is distributed in the both sides up and down of cylinder diameter in the lower flange, is separated by upper and lower major flow muscle; Secondary scavenging air belt has 2, is distributed in the left side of cylinder diameter in the lower flange, is separated by secondary guide rib; Main scavenging air belt, secondary scavenging air belt all communicate with guide section, cylinder diameter; Air outlet flue is on the right side of cylinder diameter; Radiating fin is distributed in the left and right and upper and lower sides of cylinder diameter; Bolt hole has four, is evenly distributed on upper flange plate and the lower flange.
The utility model has the advantages that the distribution of gas in the cylinder block is even, dwindle exhaust zone, thereby obviously improve the power and the torque of motor, reduced advantages such as specific fuel consumption, be applicable to the two-stroke motorcycle motor.
Following preference is described in detail the utility model in conjunction with the accompanying drawings:
Fig. 1 is the diagrammatic top view of the six scavenging air belt cylinder block used of the utility model motorcycle engine
Fig. 2 is that the master of Fig. 1 looks sketch
As Fig. 1 and Fig. 2 as can be known, main scavenging air belt 1, secondary scavenging air belt 2, major flow muscle 3, air outlet flue 4, guide section 5, upper flange plate 6, lower flange 7, radiating fin 8, bolt hole 9 is all identical with the cylinder block that existing motorcycle engine is used with cylinder hydrocarbon 11, all belong to prior art, feature of the present utility model is to increase a secondary guide rib 10 in secondary scavenging air belt 2, secondary scavenging air belt 2 separated becomes up and down two secondary scavenging air belts, gas distributes very even in cylinder like this, dwindled exhaust zone, thereby improved the power and the moment of torsion of motor widely, and reduced oil consumption widely.
