The working principle of the working principle of six-stroke motor and two stroke engine and four stroke engine is basic identical, nothing but six strokes, be intake stroke, supercharging stroke, secondary air inlet stroke, compression stroke, expansion space stroke and exhaust stroke, bent axle rotated for three weeks in the work cycle.Its six-stroke is as follows with regard to same cylinder:
1) intake stroke
In the intake stroke, intake valve is opened, exhaust valve and supercharging valve-closing, the bent axle that rotates drives piston and do retarded motion when top dead center moves to the back half trip, inertial force is downward, the ejection-spring that be installed on the ejector-seat at engine body piston lower dead center place this moment contacts with piston pin boss, absorb the downward inertial force of piston until the piston lower dead center, ejection piston moves to top dead center again, periodic additional load and bearing wear that part in the minimizing connecting rod and all axle journals bear, the vibration that also alleviates motor.(the secondary air inlet stroke, the piston action rule of expansion space stroke is the same with this trip.)
2) increase the gas stroke
In this trip, inlet and outlet Men Jun closes, and bent axle promotes piston and moved to top dead center by lower dead center, when in-cylinder pressure rise to the pressure inlet internal pressure near the time open the supercharging valve, piston pushes the supercharging tracheae with air in the cylinder.Because this moment, compression ratio is less than the normal compression ratio of work done in the cylinder, the piston head pressure ratio is less, in the piston arrives budc, because the up inertial force of piston and the tension force of connecting rod shank middle springs, make connecting rod shank elongate, allow the lift of piston reach fully can inswept firing chamber to be advanced into the supercharging tracheae more and close the supercharging valve again until air.(in addition, other cylinder is opened the supercharging valve when compression stroke begins, and the high-pressure air of supercharging tracheae enters in a short period of time closes the supercharging valve again behind the cylinder and begin to compress work done.)
3) secondary air inlet stroke
In this trip, intake valve is opened once more, and supercharging valve and exhaust valve are all closed, and the bent axle of rotation drives piston and moves to lower dead center from top dead center, air is sucked cylinder from atmosphere, after the piston arrives during half trip launch rule and intake stroke is the same for the first time.When the piston arrives lower dead center, close intake valve.
4) compression stroke
At the secondary air inlet stroke at the end, open the supercharging valve immediately, receive other cylinder and enter cylinder, when bent axle drives piston stroking upward to certain corner, close the supercharging valve when air in the supercharging tracheae will can not enter cylinder again through the pressurized air that pressure inlet stream comes.When up piston head pressure reaches normal compression ratio, the compression of the middle springs of connecting rod shank.Connecting rod shank will be got back to original length, and Piston Compression arrives top dead center, and the beginning expansion space stroke.
5) expansion space stroke
In compression stroke at the end, mixed gas burns rapidly, and inlet and outlet this moment door, supercharging valve are all closed.Piston moves and by connecting rod crankshaft rotating is moved to lower dead center and produces torque and work done.
6) exhaust stroke
At the end exhaust valve is opened when the work done stroke is approaching, and intake valve and supercharging valve are still closed, and the spring on the ejector-seat has absorbed the inertial force of descending piston, launches the piston of crossing lower dead center once more and moves to top dead center, and waste gas is forced to discharge by the push effect of piston.When half trip ran slowly on the piston arrives, piston produced inertial force upwards, added the middle springs extension that piston head pressure diminishes and makes connecting rod shank, elongated connecting rod shank, so piston can complete inswept firing chamber be discharged residual gas.
