Abstract

The utility model relates to a fuel and gas engine, which is characterized in that two sets of crank link mechanisms composed of pistons, connecting rods, and crankshafts are arranged in an engine body; the tops of the two pistons are opposite; gas inlet and outlet devices and a fuel injection ignition device are arranged on the cylinder wall between the tops of the two pistons; a gear is used for connecting the output ends of the two crankshafts. The utility model improves output power through increasing the stress area of the pistons in a cylinder, and can replace the existing various fuel and gas engines.

Description

Two-way fuel-firing gas-firing motor

The utility model is the improvement to the engine main body technology.

No matter existing motor is single cylinder, or multi-cylinder, and a piston is housed in each cylinder block, and the pressure that inflammable gas produces acts on the piston head surface, promotes piston and moves along cylinder body, and through connecting rod power is passed to bent axle, makes the crankshaft rotating acting.In order to improve power, people had many inventions to engine body structure, and the utility model also is a kind of new improvement that the motor said structure is proposed.

The purpose of this utility model is: a kind of two-way fuel-firing gas-firing motor is provided, and the lifting surface area in cylinder block improves power thereby it can increase piston.

The technical solution of the utility model is: a kind of two-way fuel-firing gas-firing motor, has body, it is characterized in that: this body is made of a cylinder and two crankcases, two pistons that the top is relative are arranged in the cylinder, bent axle is housed respectively in two crankcases, and two pistons are hinged intake and exhaust device successively with two connecting rods and two bent axles respectively, ignition mechanism is located at respectively on the cylinder wall between the two-piston top, and the output terminal of two bent axles is connected by gear.

The present technique motor is compared with available engine has increased connecting rod and corresponding body part thereof that a cover is connected and composed by piston, connecting rod, bent axle, two cover mechanism structure are identical, orientation is opposite, the other parts and the annexation thereof that constitute motor are prior art, can be identical with two strokes or four-stroke engine.During work, the pressure that the inflammable gas in the cylinder produces acts on two piston faces simultaneously, and separate the stressed back of two-piston, and the other end to the place cylinder body moves respectively, promotes two crankshaft rotating by the connecting rod that links to each other separately.The process that it is air-breathing, a work cycle is finished in compression, outburst, exhaust is same as the prior art.Connect by gear at output terminal, two power are combined into the output of making a concerted effort.

Have only a piston in the cylinder of prior art, and present technique is established two pistons in cylinder,, make piston promote bent axle rotation output power and double so the lifting surface area of piston doubled than originally.If the distance that two-piston is moved jointly equates with the distance that an original piston moves.Just do its time of identical merit and save half.Therefore, speed doubled than originally.Equal conditions uses down, and fuel saving reduces discharge amount of exhaust gas.Big because initial velocity is fast, power is used in the big rotation that produces of making a concerted effort again, it can overcome because increase resistance or the part resistance that mechanical part increases to motor.

Further specify the utility model technology below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the utility model fuel-firing gas-firing engine main body.

Fig. 2 is the sectional drawing of the utility model Fig. 1.

Among the figure, the body of motor (5) comprises a cylinder (7) and two crankcases (2) (10).Two pistons (4) (8) that the top is relative are housed in the cylinder (7), bent axle (1) (11) is housed respectively in the crankcase (2) (10), bent axle (1) is hinged by connecting rod (3) with piston (4), and bent axle (11) is hinged by connecting rod (9) with piston (8).Intake and exhaust device (6) and spark plug or oil nozzle (12) are located at respectively on cylinder (7) wall between the two-piston top.Two crankshaft end are equipped with gear (13) (15) respectively, and two gears (13) (15) are meshing with each other with gear (14) and are connected, and form the output of making a concerted effort.Other structure of present technique motor, distribution device for example, fuel delivery mechanism, lubricated, cooling, sealing etc. all can be selected two strokes or four-stroke engine prior art structure for use, so detailed description no longer.
