Working principle of the present invention is as follows:
A flywheel in α flywheel, the β flywheel is between left tooth bar and the right tooth bar, and this flywheel intermeshes with left tooth bar and right tooth bar respectively, and another flywheel and left tooth bar are meshed with a tooth bar in the right tooth bar.
In left tooth bar left side, the β flywheel is an example between the right tooth bar of left tooth bar with the α flywheel:
The cylinder in left side, top is an expansion stroke, the fuel oil blast produces thrust down, the promotion piston moves downward, external gear in left side tooth bar effect and the β flywheel, external gear effect of β flywheel and right tooth bar make it to move upward, and the cylinder in left side, below is a compression stroke simultaneously, the cylinder on right side, below is a suction stroke, and the cylinder on right side, top is an exhaust stroke; Then plug ignition acting in the cylinder in left side, below, the fuel oil blast produces goes up thrust, left side tooth bar effect and β flywheel external gear, external gear effect of β flywheel and right tooth bar, make it to move downward, the cylinder in left side, top is finished exhaust, the cylinder compression oil gas on right side, below, and the cylinder on right side, top is in suction stroke; The cylinder on right side, below is in expansion stroke, the oil gas blast produces and goes up thrust in the right cylinder of below, right tooth bar effect and β flywheel external gear, external gear effect of β flywheel and left tooth bar, make it to move downward, the cylinder compression on right side, top, the cylinder in left side, top is a suction stroke, the cylinder in left side, below is an exhaust stroke; The cylinder acting on right side, top, top right cylinder intermediate fuel oil blast produces thrust down, the promotion piston moves downward, right tooth bar effect and β flywheel external gear, external gear effect of β flywheel and left tooth bar, make it to move upward, the cylinder on right side, below is finished exhaust stroke, and the cylinder in left side, top is a compression stroke, and the cylinder in left side, below is a suction stroke, and then the cylinder in left side, top begins acting, finishes the one-period circulation.
Piston moves down in the cylinder in left side, top, piston also moves down in the cylinder in left side, below simultaneously, left tooth bar between the cylinder in the cylinder in left side, top and left side, below moves down, external gear in the rack drives α flywheel of a left side clockwise rotates, the α flywheel shaft also clockwise rotates, and the A gear also clockwise rotates, and the external gear that drives in the γ flywheel rotates counterclockwise, drive the γ flywheel shaft and rotate counterclockwise, the γ flywheel shaft rotates and exports as power.
Piston moves up simultaneously in the cylinder in the cylinder in left side, top on the left of piston and the below, in the cylinder on right side, top in the cylinder on piston and right side, below piston move down simultaneously, left side tooth bar moves up, right tooth bar moves down, external gear in the rack drives α flywheel of a left side rotates counterclockwise, α flywheel shaft inertia rotates, simultaneously, right tooth bar moves down, and the external gear in the right rack drives β flywheel clockwise rotates, and the β flywheel shaft also clockwise rotates, the B gear also clockwise rotates, the external gear that drives in the γ flywheel rotates counterclockwise, and drives the γ flywheel shaft and rotates counterclockwise, and the γ flywheel shaft rotates and exports as power.
Piston moves downward in the cylinder in the cylinder in left side, top on the left of piston and the below, piston drives the anti-valve tooth bar of positive valve tooth bar and moves down, the positive cam flywheel of positive valve rack drives rotates counterclockwise side-looking and drives positive cam flywheel shaft and rotate counterclockwise, the inverse cam flywheel clockwise rotates, because flywheel structure, the inverse cam flywheel shaft rotates counterclockwise with it and is independent of each other, and this process camshaft rotated for 1/4th weeks.
Valve tooth bar pressure pin can be installed on the left tooth bar, piston moves upward in the cylinder in the cylinder in left side, top on the left of piston and the below, valve tooth bar pressure pin on this piston-rack drives the positive valve tooth bar, anti-valve tooth bar moves up, the positive cam flywheel of positive valve rack drives clockwise rotates side-looking, the inverse cam flywheel rotates counterclockwise, and drives the inverse cam flywheel shaft and rotates counterclockwise.Because flywheel structure, positive cam flywheel shaft rotate counterclockwise with positive cam flywheel rotation and be independent of each other, this process camshaft rotated for 1/4th weeks.Valve tooth bar pressure pin also can be installed on the right tooth bar.
An acting circulation, camshaft rotates a week, controls each air chamber intake valve, exhaust valve.
Air chamber can be fixed with hydraulic pressure installation, only must the regulator solution pressing system when regulating discharge capacity.
When regulating discharge capacity, air chamber, positive valve tooth bar, anti-valve tooth bar be cylinder slip relatively all, but because the positive valve tooth bar, that anti-valve tooth bar stretches into cylinder interior length is constant, so the camshaft rotation period is also consistent with the adjustable displacement engine for rack driving cycle after the change discharge capacity.
Camshaft can be the same with the pto installation method.
