Abstract
A double-crankshaft four-stroke engine comprises an air cylinder provided with an air inlet and an air outlet. A piston is arranged in the air cylinder. The bottom of the piston is connected with a first crankshaft. The first crankshaft is connected with an output gear through a second crankshaft. When the engine operates, the air inlet stroke and the compression stroke of the engine are different from the acting stroke and the exhaust stroke of the engine. Compared with a traditional engine, the double-crankshaft four-stroke engine has the advantages that under the condition that the air inlet stroke and the compression stroke are the same, the acting stroke of the piston of the engine is larger than that of a piston of the traditional engine, and energy in the air cylinder is fully utilized at the moment.

Goal of the invention:
The invention provides a kind of double-crankshaft four-stroke engine, its objective is the problem that solution is in the past existing.
Technological scheme:
A kind of double-crankshaft four-stroke engine, comprise the cylinder with suction port and air outlet, be provided with piston in cylinder, the bottom of piston is connected with the first bent axle, and the first bent axle is connected with output gear by the second bent axle;
First bent axle comprises bent axle forearm and bent axle postbrachium, and the front end of bent axle postbrachium connects the rear end of bent axle forearm by front rotary shaft, the front end of bent axle forearm is connected with piston base, and bent axle postbrachium is arranged in rear rotating shaft;
Second bent axle is man type bent axle, and this bent axle comprises bent axle principal arm, first time bent axle support arm and second time bent axle support arm, and upper bent axle principal arm, first time bent axle support arm and second time bent axle support arm are flexibly connected by common central rotating shaft and form herringbone structure; Upper bent axle principal arm is connected to the medium position of bent axle postbrachium, and this medium position is arranged between front rotary shaft and rear rotating shaft;
First time bent axle support arm is connected by rotating shaft and first handle that links, and the first interlock handle is connected to the rotatingshaft of the first actuation gear and drives the first actuation gear to rotate;
Second time bent axle support arm is connected by rotating shaft and second handle that links, and the second interlock handle is connected to the rotatingshaft of the second actuation gear and drives the second actuation gear to rotate;
First actuation gear engages with the second actuation gear.
Cylinder is bottle shape, and piston is arranged on bottleneck, and does in bottleneck and move around, and the first actuation gear and the second actuation gear are arranged in the body in cylinder.
Suction port and air outlet place are provided with open and close valve.
Advantage and effect
The present invention is a kind of double-crankshaft four-stroke engine, when motor operationally, its (air inlet, compression) stroke is unequal with (workmanship, exhaust) stroke, its advantage is compared with conventional engines machine, under the condition that (air inlet, compression) stroke is identical, the expansion space stroke of this engine piston is greater than the expansion space stroke of conventional engines piston, and the energy at this moment in cylinder is just utilized fully, and this is one.
Second:
Rotate because this motor is double-crankshaft synchronous interaction, so this motor of the every rotating 360 degrees of bent axle just have a work cycle (conventional engines need 720 degree just have a work cycle) thus when this engine speed, with conventional engines when rotating speed is identical, this motor will be more than conventional engines work times one times, and this can increase substantially engine operating efficiency.
3rd: from the structural feature of new work engine, in the condition of air displacement identical with conventional engines, new work engine can design more large-diameter, stroke ratio.And conventional engines cannot accomplish this at all
Point.And larger cylinder diameter, stroke are compared to and improve air inlet, improving the thermal efficiency has decisive role, and this point is easy to prove from mathematics, fluid mechanics and calorifics theory.See that the efficiency of new work engine has raising by a relatively large margin than the efficiency of conventional engines by above feature.(30-35) % can be reached from theory and practice (prototype experiment) fuel-economizing
4th: due to the lengthening of new work engine piston expansion space stroke, make the burning of fuel more abundant, this not only increases the utilization ratio of fuel, more means that the pollution of exhaust emissions is lower, exhaust noise is less.
