Abstract
The utility model discloses a two-stroke cylinder body with an auxiliary scavenging air duct, which comprises a cylinder body and a main scavenging air duct, wherein radiating fins are arranged on the cylinder body; the two-stroke cylinder body with the auxiliary scavenging air duct is characterized in that an alloy cylinder sleeve is arranged inside the cylinder body; a scavenging opening communicated with the main scavenging air duct is formed in the alloy cylinder sleeve; a diffluent trough is arranged below the scavenging opening; a lubrication hole is formed in the diffluent trough; the two ends of the diffluent trough are both communicated with the main scavenging air duct; a guiding rib is arranged inside the main scavenging air duct; the main scavenging air duct is divided into a first scavenging air duct and a second scavenging air duct by the guiding rib; the auxiliary scavenging air duct is arranged at the lower part of the alloy cylinder sleeve; an auxiliary scavenging hole is formed in the middle of the auxiliary scavenging air duct; and the auxiliary scavenging hole is connected with the diffluent trough. The two-stroke cylinder body with the auxiliary scavenging air duct can effectively solve the technical problems of environment pollution, high content of harmful components in tail gas, and high fuel consumption rate of a petrol engine, namely the environment is improved and the cost is saved.
Description
Technical field the utility model belongs to the technology of gasoline engine field, is specifically related to a kind of two-stroke cylinder block with secondary scavenging air belt.
Background technique has general two-stroke gasoline engine cylinder body now, at inner surface of cylinder block chromium coating is set usually, and the two-stroke gasoline engine cylinder body of this structure is because there is the technical problem of befouling environment in inner surface of cylinder block chromium plating; In addition, because scavenging air belt is open architecture and directly is communicated with cylinder body, also there are the content height of harmful components in the tail gas (HC+NOx), the high technical problem of fuel consumption rate of petrol engine.
The summary of the invention the purpose of this utility model is to solve the high technical problem of fuel consumption rate that prior art exists harmful components content height and petrol engine in befouling environment, the tail gas, provide a kind of two-stroke cylinder block with secondary scavenging air belt, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of two-stroke cylinder block with secondary scavenging air belt of the utility model, it comprises cylinder body and main scavenging air belt, described cylinder body is provided with radiating fin; Its main points are to be provided with alloy cylinder sleeve in the described cylinder body; Described alloy cylinder sleeve is provided with the scavenging port that is communicated with main scavenging air belt; The below of described scavenging port is provided with splitter box; Described splitter box is provided with lubrication hole; The two ends of described splitter box communicate with main scavenging air belt respectively; Be provided with guiding rib in the described main scavenging air belt; Described guiding rib is divided into first scavenging air belt and second scavenging air belt with main scavenging air belt; The bottom of described alloy cylinder sleeve is provided with secondary scavenging air belt; The centre of described secondary scavenging air belt is provided with secondary transfer port; Described secondary transfer port is connected with splitter box.
The utility model effectively solves the high technical problem of fuel consumption rate that prior art exists harmful components content height and petrol engine in befouling environment, the tail gas, has namely improved environment and has saved cost again.
Description of drawings Fig. 1 is the utility model structural representation;
Fig. 2 is the plan structure schematic representation of Fig. 1.
Among the figure 1, cylinder body 2, alloy cylinder sleeve 3, scavenging port 4, main scavenging air belt 5, suction port 6, first scavenging air belt 7, guiding rib 8, second scavenging air belt 9, lubrication hole 10, splitter box 11, secondary transfer port 12, secondary scavenging air belt
Embodiment sees figures.1.and.2, a kind of two-stroke cylinder block with secondary scavenging air belt of the utility model, and it comprises cylinder body 1 and main scavenging air belt 4, is provided with alloy cylinder sleeve 2 in the described cylinder body 1; Described alloy cylinder sleeve 2 is provided with the scavenging port 3 that is communicated with main scavenging air belt 4; The below of described scavenging port 3 is provided with splitter box 10; Described splitter box 10 is provided with lubrication hole 9; The two ends of described splitter box 10 communicate with main scavenging air belt 4 respectively; Be provided with guiding rib 7 in the described main scavenging air belt 4; Described guiding rib 7 is divided into first scavenging air belt 6 and second scavenging air belt 8 with main scavenging air belt 4; The below of described alloy cylinder sleeve 2 is provided with secondary scavenging air belt 12; Be provided with secondary transfer port 11 in the middle of the described secondary scavenging air belt 12; Described secondary transfer port 11 is connected with splitter box 10.
After fuel mixture is compressed, directly enter the firing chamber through main scavenging air belt 4, and the fuel mixture that flows enters into splitter box 10 respectively by main scavenging air belt 4 and secondary transfer port 11, acts on the lubricated blind area of cylinder wall and piston through lubrication hole 9 in secondary scavenging air belt 12.Because the effect of secondary scavenging air belt 12, part fuel oil carries out abundant effective lubricating through secondary scavenging air belt to casing wall, piston, the piston ring of former lubricated blind area, has also taken away a part of heat, reduces or has avoided scuffing of cylinder bore, reduce the gasoline engine fuel consumption rate, improved the output power of petrol engine.
