Description
Technical field
The present invention relates to field of power machinery, specifically a kind of structure of internal combustion engine.
Background technique
Current single crankshaft internal combustion engine, through the fuel acting output power such as burning vapour, diesel oil, while operating
A part of kinetic energy is also consumed, keeps the power utilization rate of reality output relatively low.
Summary of the invention
The present invention is to solve internal combustion engine, and the relatively low problem of the power utilization rate of reality output provides one kind at one
Two pistons of installation make the engine moved toward one another in cylinder.
The technical scheme is that a kind of more crank-axle engines, including cylinder block, piston, connecting rod, crankshaft, flywheel, machine
Shell is characterized in that, dress is there are two opposite piston in casing a cylinder block, and there are burnings between two pistons
Room, the outside of piston are equipped with external connecting rod, and the outer end of connecting rod is equipped with crankshaft, synchronous flywheel is housed on crankshaft；In the middle part of cylinder block
There are air inlet on upper side wall, equipped with radial inlet valve on air inlet, be furnished with inlet-valve spring on inlet valve, inlet valve it is outer
End is equipped with vertical inlet valve rocker, and the other end of inlet valve rocker is fitted with inlet camshaft；Lower wall in the middle part of cylinder block
On there are exhaust outlet, equipped with radial exhaust valve on exhaust outlet, exhaust valve spring is housed on exhaust valve, the outer end of exhaust valve is equipped with
The other end of vertical exhaust valve rocker, exhaust valve rocker is fitted with exhaust camshaft.
When work, two crankshaft-synchronous are rotated by synchronous flywheel, are drawn two pistons by inner dead point is synchronous by connecting rod
To outer dead point, crankshaft drives inlet camshaft by transmission device simultaneously, and inlet camshaft stirs inlet valve rocker compression
Inlet-valve spring opens inlet valve, air from the intracorporal combustion chamber of air inlet inspiration cylinder, while fuel oil be atomized or direct-injection into
In combustion chamber.
The IC Intake Valve Closes when piston reaches outer dead point, synchronous crankshaft continue rotation forces piston to inner dead point motion compresses
Air and fuel oil.
Igniter starts igniting after compression reaches inner dead point or high temperature and pressure lights atomized fuel, and the gas of expansion will
Piston pushes outer dead point to.
When piston reaches outer dead point, synchronous crankshaft drives exhaust camshaft by transmission device, stirs exhaust valve and shakes
Arm compression exhaust door spring opens exhaust valve, and high-temp waste gas is excluded by exhaust outlet.
The present invention can design more than two synchronous crankshafts as needed to be made under the drive of synchronous flywheel or other means
Piston on two crankshafts or multiple crankshafts drives the single piston on every two crankshaft to do in the same combustion chamber by connecting rod
Move toward one another work.
The solution have the advantages that one kind may be implemented and effectively improve engine torque using above-mentioned technical solution
Power increases power output, reduces more crank-axle engines of abrasion and oil consumption.
Detailed description of the invention
Fig. 1 is structural front view of the invention, and the attached drawing that makes an abstract.
1 casing, 2 connecting rods, 3 exhaust camshafts, 4 exhaust valve rockers, 5 exhaust valve springs, 6 exhaust valves, 7 rows in the figure
Port, 8 synchronous flywheels, 9 combustion chambers, 10 cylinder blocks, 11 air inlets, 12 inlet valves, 13 inlet-valve springs, 14 inlet valve cams
Axis, 15 inlet valve rockers, 16 pistons, 17 crankshafts.
Specific embodiment
Embodiment with reference to the accompanying drawing, the present invention is further described.
As shown, in the cylinder block 10 in casing 1 dress there are two opposite piston 16, between two pistons 16 there are
Combustion chamber 9, the outside of piston 16 are equipped with external connecting rod 2, and the outer end of connecting rod 2 is equipped with crankshaft 17, winged equipped with synchronizing on crankshaft 17
Wheel 8；There are air inlet 11 on 10 middle part upper side wall of cylinder block, equipped with radial inlet valve 12 on air inlet 11, on inlet valve 12
Equipped with inlet-valve spring 13, 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 matched
Equipped with inlet camshaft 14；There are exhaust outlet 7 in 10 middle part lower wall of cylinder block, equipped with radial exhaust valve on exhaust outlet 7
6, exhaust valve spring 5 is housed on exhaust valve 6, the outer end of exhaust valve 6 is equipped with vertical exhaust valve rocker 4, exhaust valve rocker 4 it is another
One end is fitted with exhaust camshaft 3.
When work, by synchronous flywheel 8 by two 17 synchronous rotaries of crankshaft, by connecting rod 2 by two pistons 16 by inner dead point
Synchronize and be pulled to outer dead point, crankshaft 17 simultaneously by transmission device drive inlet camshaft 14, inlet camshaft 14 stir into
Valve rocker 15 compresses inlet-valve spring 13 and opens inlet valve 12, and air is from the combustion chamber 9 in air inlet inspiration cylinder block 10, together
When fuel oil be atomized or direct-injection is into combustion chamber 9.
When piston 16 reaches outer dead point, inlet valve 12 is closed, and synchronous crankshaft 17 continues rotation forces piston 16 to inner dead point
Motion compresses air and fuel oil.
Igniter starts igniting after piston 16, which compresses, reaches inner dead point or high temperature and pressure lights atomized fuel, expansion
Gas pushes piston 16 to outer dead point.
When piston 16 reaches outer dead point, synchronous crankshaft 17 leads to transmission device and drives exhaust camshaft 3, stirs exhaust valve
Rocker arm 4 compression exhaust door spring 5 opens exhaust valve 6, and high-temp waste gas is discharged to outside casing 1 by exhaust outlet 7.
