Description
Technical field
The present invention relates to field of power machinery, specifically a kind of structure of explosive motor.
Background technology
Current single crankshaft internal combustion engine, by the fuel such as vapour, the diesel oil acting output power that burns, while operating a part of kinetic energy is also consumes, and makes the power utilization rate of reality output low.
The content of the invention
The present invention is to solve explosive motor, the low problem of the power utilization rate of reality output, there is provided a kind of that the engine that two pistons make move toward one another is installed in a cylinder.
The technical scheme is that, a kind of many crank-axle engines, including cylinder block, piston, connecting rod, bent axle, flywheel, casing, it is characterized in that, two opposite pistons are housed in a cylinder block in casing, combustion chamber is left between two pistons, the outside of piston is equipped with external connecting rod, the outer end of connecting rod is equipped with bent axle, and synchronous flywheel is housed on bent axle；Air inlet is left on the upper side wall of cylinder block middle part, the inlet valve equipped with radial direction on air inlet is furnished with inlet-valve spring on inlet valve, the outer end of inlet valve is equipped with vertical inlet valve rocker, and the other end of inlet valve rocker is fitted with inlet camshaft；Exhaust outlet is left in the lower wall of cylinder block middle part, the exhaust valve equipped with radial direction on exhaust outlet is equipped with exhaust valve spring on exhaust valve, the outer end of exhaust valve is equipped with vertical exhaust valve rocker, and the other end of exhaust valve rocker is fitted with exhaust camshaft.
During work, two crankshaft-synchronous are rotated by synchronous flywheel, two pistons are synchronously pulled to by outer dead point by inner dead point by connecting rod, bent axle drives inlet camshaft by transmission device simultaneously, inlet camshaft stirs inlet valve rocker compression inlet-valve spring and opens inlet valve, combustion chamber of the air from air inlet inspiration cylinder body, while fuel oil is atomized or direct-injection enters burning interior.
The IC Intake Valve Closes when piston reaches outer dead point, synchronous bent axle continues rotation forces piston to inner dead point motion compresses air and fuel oil.
Igniter starts igniting or HTHP lights atomized fuel after being compressed to up to inner dead point, and the gas of expansion pushes piston to outer dead point.
When piston reaches outer dead point, synchronous bent axle drives exhaust camshaft by transmission device, stirs exhaust valve rocker compression exhaust door spring and opens exhaust valve, and high-temp waste gas are excluded by exhaust outlet.
The present invention can as needed design two or more synchronization bent axle, under the drive of synchronous flywheel or alternate manner, make two bent axles or the piston on multiple bent axles, drive the single piston on each two bent axle to do move toward one another work in same combustion chamber by connecting rod.
The solution have the advantages that, using above-mentioned technical scheme, it is possible to achieve one kind effectively improves engine torque power increases power output, reduce many crank-axle engines of abrasion and oil consumption.
Description of the drawings
Fig. 1 is the structural front view of the present invention, and the accompanying drawing that makes an abstract.
In figure, 1 casing, 2 connecting rods, 3 exhaust camshafts, 4 exhaust valve rockers, 5 exhaust valve springs, 6 exhaust valves, 7 exhaust outlets, 8 synchronous flywheels, 9 combustion chambers, 10 cylinder blocks, 11 air inlets, 12 inlet valves, 13 inlet-valve springs, 14 inlet camshafts, 15 inlet valve rockers, 16 pistons, 17 bent axles.
Specific embodiment
Embodiment below in conjunction with the accompanying drawings, the present invention is further described.
As illustrated, being equipped with two relative pistons 16 in the cylinder block 10 in casing 1, combustion chamber 9 is left between two pistons 16, the outside of piston 16 is equipped with external connecting rod 2, and the outer end of connecting rod 2 is equipped with bent axle 17, and synchronous flywheel 8 is housed on bent axle 17；Air inlet 11 is left on the middle part upper side wall of cylinder block 10, inlet valve 12 equipped with radial direction on air inlet 11, it is furnished with inlet-valve spring 13 on inlet valve 12, the outer end of inlet valve 12 is equipped with vertical inlet valve rocker 15, and the other end of inlet valve rocker 15 is fitted with inlet camshaft 14；Exhaust outlet 7 is left in the middle part lower wall of cylinder block 10, the exhaust valve 6 equipped with radial direction on exhaust outlet 7 is equipped with exhaust valve spring 5 on exhaust valve 6, the outer end of exhaust valve 6 is equipped with vertical exhaust valve rocker 4, and the other end of exhaust valve rocker 4 is fitted with exhaust camshaft 3.
During work, by synchronous flywheel 8 by two synchronous rotaries of bent axle 17, two pistons 16 are synchronously pulled to by outer dead point by inner dead point by connecting rod 2, bent axle 17 drives inlet camshaft 14 by transmission device simultaneously, inlet camshaft 14 stirs the compression inlet-valve spring 13 of inlet valve rocker 15 and opens inlet valve 12, combustion chamber 9 of the air from air inlet inspiration cylinder block 10, while fuel oil is atomized or direct-injection is entered in combustion chamber 9.
When piston 16 reaches outer dead point, inlet valve 12 is closed, and synchronous bent axle 17 continues rotation forces piston 16 to inner dead point motion compresses air and fuel oil.
Igniter starts igniting or HTHP lights atomized fuel after piston 16 is compressed to up to inner dead point, and the gas of expansion pushes piston 16 to outer dead point.
When piston 16 reaches outer dead point, synchronous bent axle 17 leads to transmission device and drives exhaust camshaft 3, stirs 4 compression exhaust door spring of exhaust valve rocker 5 and opens exhaust valve 6, and high-temp waste gas are discharged to outside casing 1 by exhaust outlet 7.
