Description
Technical field
The utility model relates to a kind of internal-combustion engine, specifically is a kind of duct formula straight-shaft internal-combustion engine.
Background technique
Stroke piston combustion engine is present widely used internal-combustion engine, be that piston is done straight reciprocating motion in cylinder, by connecting rod the to-and-fro motion of piston is become then and rotatablely move, and via pto output, but its complex structure, volume is bigger, and in the acting process, the connecting rod big energy-consuming makes the useful horsepower of internal-combustion engine not high, causes fuel availability low.
Summary of the invention
The utility model provides a kind of duct formula straight-shaft internal-combustion engine in order to solve the existing problem that stroke piston combustion engine useful horsepower is not high, fuel availability is low.
The utility model is to adopt following technological scheme to realize: a kind of duct formula straight-shaft internal-combustion engine, comprise housing, by the pto of spring bearing support fixation in housing, housing is made of the cylinder cap that is used to contain the oil sump of lubricant oil and is fixed in the oil sump top; Have at least one group of circular arc duct on the described cylinder cap, every group comprises at least one circular arc duct, and circular arc duct top is provided with the spark plug fixed hole, and cylinder cap has the intake and exhaust pipeline that communicates with the circular arc duct; Be fixed with at least one on the pto and which is provided with the piston wheel that forms the airtight circular-arc fin of some inclinations that cooperates of rotation with inboard wall of cylinder cover, the number of piston wheel is identical with the group number of circular arc duct, and the circular-arc fin of inclination on the piston wheel cooperates the airtight firing chamber of formation with the circular arc duct.
During use, deflagrating mixture enters circular-arc fin via the intake and exhaust pipeline and cooperates in the airtight firing chamber that forms with the circular arc duct, through plug ignition, the circular-arc flap surface of inclination of the direct impact piston wheel of expansive force that deflagrating mixture burning back produces, promoting the piston wheel rotates, thereby driving pto rotates, output power, finish chemical energy is converted into the mechanokinetic process, when the piston wheel rotates, the waste gas that deflagrating mixture burning back produces is under the promotion of the fin of piston wheel, via the circular arc duct, the intake and exhaust pipeline is discharged, as has only a circular arc duct, then advance, exhaust all is that the intake and exhaust pipeline through this circular arc duct carries out, air inlet, igniting, exhaust is carried out successively, and the time staggers mutually, and promptly the working procedure of this internal-combustion engine has comprised air inlet, acting (igniting), three processes of exhaust.Wherein, the effect that contains the lubricant oil in oil sump is except lubricated, also play the effect of sealing, guarantee that promptly the circular-arc fin of inclination on the piston wheel cooperates the seal of the firing chamber that forms with the circular arc duct, with the expansive force (or explosive power) that reaches deflagrating mixture burning back generation the best promotion effect to fin.
Compared with prior art, the utility model is offered the circular arc duct on cylinder cap, and on pto, be provided with some can with inboard wall of cylinder cover form to rotate airtight that cooperate, cooperates the piston of the circular-arc fin of inclination of formation inflammable gas combustion space to take turns with the circular arc duct, the kinetic force that inflammable gas burning back is produced is directly exported by pto via the piston wheel, loaded down with trivial details medium tache be needn't pass through during this time, thereby useful horsepower and fuel availability improved.
The utility model is rational in infrastructure, and using effect is good, the useful horsepower height, and the fuel availability height has high promotional value.
