Embodiment
A kind of twin shaft intake and exhaust bavin petrol engine
Illustrate (for the first cylinder) with four of four-cylinder diesel engine work strokes below:
One, intake stroke
Rotated by bent axle 21, by time rule belt or time rule chain-driving Intake shaft 9, exhaust shaft 10 rotate, exhaust shaft 10, by the closed condition at the end of opening state during exhaust stroke to exhaust stroke, is closed during intake stroke always.Intake shaft 9 is by the rotation of the closed condition at the end of exhaust stroke to opening state, and be communicated with cylinder cap suction port 15, piston 19 is descending by top dead center, and it is inner that air enters Intake shaft 9 by intake manifold, to suction port 1, then to cylinder cap suction port 15, enters firing chamber.Bent axle 21 revolves turnback, and piston 19 comes downwards to lower dead center by top dead center, and relief opening 5 is closed always, Intake shaft 9 90-degree rotation, and suction port 1 is closed by being closed to unlatching again, and intake stroke terminates.
2, compression stroke
Bent axle 21 revolves turnback, and piston 19 walks to top dead center by lower dead center, and Intake shaft 9, exhaust shaft 10 90-degree rotation, suction port 1, relief opening 5 are closed always, and air is compressed, and compression stroke terminates.
3, working stroke
Piston 19 to atdc, air is compressed into Pressure maximum value, oil nozzle 25 oil spout, diesel combustion, produce pressure, promote piston 19 descending, bent axle 21 revolves turnback, piston 19 comes downwards to lower dead center by top dead center, and suction port 1, relief opening 5 are closed always, and working stroke terminates.
4, exhaust stroke
Bent axle 21 rotates, piston 19 is up by lower dead center, exhaust shaft 10 rotates, relief opening 5 is opened, Intake shaft 9 rotates but suction port 1 is closed always, and waste gas is squeezed to head exhaust mouth 16 by pressure itself and the up thrust of piston 19, then to exhaust shaft relief opening 5, by exhaust shaft 10 inside to gas exhaust manifold 23, discharge motor.Bent axle 21 revolves turnback, and piston 19 goes upward to top dead center by lower dead center, exhaust shaft 10 90-degree rotation, and relief opening 5 axle closes to unlatching and closes, Intake shaft 9 90-degree rotation, but suction port 1 is closed always, and exhaust stroke terminates.
So move in circles, drive engine operation.
