Embodiment
Referring to Fig. 1 single chamber two stroke engine of the present invention device; Cylinder assembly 100 comprises cylinder body 110, spark plug mouth 111, gas port 112, air conditioning mouth 113, piston 120, spark plug 130, one-way valve 1121, electromagnetic switch valve 1122, air conditioning pressure-limit valve 1131 and relief opening 114, suction port 115.
Referring to Fig. 2 is the first step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 is marked shown in the arrow by Fig. 2; In lower dead center to up position; (be meant the upper space of piston 120 cylinder body 110 in the cylinder body 110, below no longer repeat to introduce) suction port 115 and relief opening 114 whole and atmosphere in this moment cylinder body 110, it is identical with atmosphere to be full of fresh air pressure in the cylinder body 110; Air conditioning pressure-limit valve 1131 is opened, and electromagnetic switch valve 1122 is in closed condition.
Referring to Fig. 3 is second step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 is marked shown in the arrow by Fig. 3; In lower dead center to the position that is up to air conditioning pressure-limit valve 1131, then 1131 exhausts of air conditioning pressure-limit valve will finish by Fig. 3 mark shown in the arrow (the compression ratio total measurement (volume) position of this position) electromagnetic switch valve 1122 this moment for setting open under the pressure of oil feed pump will greater than this moment cylinder body 110 internal pressures fuel mark by Fig. 3 through one-way valve 1121 and spray into shown in the arrow in the cylinder body 110.
Referring to Fig. 4 is the 3rd step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 is marked shown in the arrow pressure increasing electromagnetic switch valve 1122 that continues in being up to soon parallel this moment with one-way valve 1121 of cylinder body 110 by Fig. 4 and is closed.
Referring to Fig. 5 is the 4th step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 is marked shown in the arrow by Fig. 5 and is continued to light the mixed gas of compression and promote piston 120 and go downwards to being up to top dead center spark plug 130 this moment.
Referring to Fig. 6 is the 5th step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 by Fig. 6 mark drive to downwards shown in the arrow one-way valve 1121 when following because the expansion air pressure of cylinder body 110 internal combustion causes one-way valve 1121 to be closed automatically very greatly, this moment, electromagnetic switch valve 1122 also was in closed condition.
Referring to Fig. 7 is the 6th step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 is marked shown in the arrow by Fig. 7 that the pressure in the cylinder body 110 still cause air conditioning pressure-limit valve 1131 also to be in closing automatically under the pressure very greatly when continuing to drive to air conditioning pressure-limit valve 1131 belows downwards, and the force pistons 120 in the cylinder body 110 further prolong acting.
Referring to Fig. 8 is the 7th step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 is marked shown in the arrow when continuing to drive to cylinder body 110 relief openings 114 downwards by Fig. 8, and waste gas also has in cylinder body 110 under certain pressure discharges from relief opening 114.
Referring to Fig. 9 is the 8th step of single chamber two stroke engine device work schematic representation of the present invention; Piston 120 is marked shown in the arrow when continuing to drive to lower dead center downwards by Fig. 9; Because cylinder body 110 internal volumes strengthen and to form negative pressure with atmosphere and cause fresh air to open entering cylinder body 110 through the suction port 115 and the air conditioning pressure-limit valve 1131 of release pressure to be marked shown in the arrow by Fig. 9, thereby accomplish a round work cycle.
