Abstract
A two-stroke internal combustion engine with direct current air change type is provided, which is characterized in that a cylinder lower part is opened with an air inlet hole, a cylinder lid right part is opened with an air exhaust hole, the left part is arranged with an oil blowing tube, and the middle part is arranged with an ignition plug. Because the airflow enters from the cylinder lower part, and bleeds from the upper part, therefore there's no 'dead spot' during air change with high air change efficiency, which can improve the power of the internal combustion engine.
Description
The utility model relates to a kind of internal-combustion engine, specifically, is direct current ventilation direct injection two-stroke internal-combustion engine.
Gas Exchange Process of Internal Combustion Engine efficient is the factor that power of IC engine is had considerable influence, improves scavenging efficiency, just can improve the power of internal-combustion engine.Common two stroke IC engine inlet hole and exhaust port are all on the top of piston lower dead center, and just exhaust port is a little more than inlet hole.Like this, the glide path of air-flow in cylinder is " Ω " shape, thereby ventilation " dead point " can occur, makes gas hold-up be difficult for being replaced in " dead point ".
The purpose of this utility model is to improve scavenging efficiency as far as possible, and then improves power of IC engine.
The utility model is to realize purpose of design like this.
Below cylinder, be positioned at the periphery on the top of piston lower dead center, have a plurality of inlet holes; Upper right in cylinder head has exhaust port; Oil nozzle is equipped with on upper left side in cylinder head; Above the middle part of cylinder head, igniter plug is housed.
During work, after the piston acting, rely on inertia to continue to come downwards to lower dead center, at this moment, inlet hole replenishes fresh air to cylinder rapidly, relies on the inertia piston through up after bottom dead center, crosses inlet hole, and air inlet stops, the Piston Compression air; Piston is during near top dead center, and oil nozzle ejection high pressure oil haze is mixed rapidly with air, and after a while, the igniter plug ignition is done work, and piston is pushed descending, and exhaust port is opened, and combustion gas is finished a circulation.
Gas of the present utility model in cylinder by the bottom enter, top discharges; Be the direct current shape, therefore, do not have at " dead point ", can fully change, can improve scavenging efficiency.
Accompanying drawing is the utility model schematic representation.
Below, in conjunction with the accompanying drawings, a non-limiting examples is illustrated.
Below cylinder 4, be positioned at the periphery on the top of piston 5 lower dead center, have a plurality of inlet holes 7, have exhaust port 3, oil nozzle 8 is housed on the upper left side of cylinder head 2 in the upper right of cylinder head 2; Igniter plug 1 is housed above the middle part of cylinder head 2.
During work, after piston 5 actings, rely on inertia, under the drive of bent axle 6, continue to come downwards to lower dead center, at this moment, inlet hole 7 replenishes fresh air rapidly in cylinder 4; Rely on inertia, piston 5 is up through only accounting for the back down, crosses inlet hole 7, and air inlet stops, piston 5 pressurized air.Piston 5 is during near top dead center, and oil nozzle 8 ejection high pressure oil hazes mix rapidly with air.After a while, igniter plug 1 ignition, acting, piston 5 is pushed descending, and exhaust port 3 is opened, and combustion gas is finished once circulation.
The utility model is owing to fully take a breath, and the high pressure oil of ejection has front end mist of oil group oil concentration advantages of higher, so when oil-gas ratio is very low, still can light a fire, can fully burn, pollutant is few in the exhaust gas discharged, help environmental protection, can increase substantially power of IC engine.
