Description
Technical field
The present invention relates to reciprocating engine, a kind of more precisely to-and-fro motion with piston changes into the motor combined type motion that rotatablely moves of pto, belongs to technical field of engines.
Background technique
At present, the motion of reciprocating engine major part is a connecting rod, and its effect is the to-and-fro motion with piston, by connecting rod, changes into rotatablely moving of crankshaft.Its working principle is, fuel burns in cylinder combustion and produces heat energy during engine operation, and when gases are heated, they expand promotes piston and move, and is delivered to bent axle and makes its rotation acting through connecting rod.In the course of the work, heat energy will be realized many times continuous transformation to mechanical energy through associating, a work cycle is all experienced in each transformation, piston moves from top to bottom or from top to bottom and once is called a stroke, general conventional engine is finished a work cycle needs 4 strokes, i.e. suction stroke, compression stroke, acting (outburst) stroke and exhaust stroke.A work cycle, piston up and down reciprocatingly 4 times.Crankshaft rotating two circles.In a work cycle, has only working stroke, it is active stroke by piston throw crank linkage mechanism, the power of its excess-three stroke, for single-cylinder engine, being drive crank and connecting rod movement by the inertial force of accumulated energy flywheel, for multicylinder engine, then is the cylinder operation that is driven other non-working stroke by the piston that carries out working stroke.
At working stroke, when piston during at top dead center position, fuel is sprayed into by in the air of Piston Compression, the fuel combustion blast, and gas expands and promotes piston and move downward acting, the stressed maximum of piston of this moment.Characteristic by connecting rod has determined, this moment, crank and connecting rod were in line, the moment radius that piston action power is equivalent to crankshaft center is very little, to bent axle produce moment of torsion equal amassing of power and moment radius, therefore less by the moment of torsion of the outside output of bent axle, and, with moving downward of piston, bent axle also rotates simultaneously, and the moment radius that acts on crankshaft center increases thereupon, but owing to the volume of cylinder enlarges simultaneously, gas reduces rapidly the pressure of piston, therefore, the output of the moment of torsion of bent axle does not reach best condition yet, fails to give full play to the best efficiency that the fuel combustion blast is produced.In the movement process of piston, the variation of active force and moment radius is also bigger, caused the unstability of bent axle moment of torsion output, can not give full play to piston when top dead center, the effect that fuel combustion produces to the piston maximum thrust, directly influence the performance of engine efficiency level, cause the huge waste of the energy.
At the problems referred to above, a large amount of experts and scholars are devoted to solve the problem of this respect always both at home and abroad, (as described in following technical documentation) appears in existing many patents as new work engine principle aspects such as rotary engines, but because its complex structure, control system is difficult to technical problems such as realization, and fails to widely apply on producing.Its motions of internal-combustion engine such as the diesel engine of using, petrol engine remain brace and connecting rod framework now.
