Abstract
The utility model relates to an air inlet elbow of engines, in particular to an air inlet elbow of a single cylinder engine, which comprises an air inlet elbow body. An oil injection nozzle seat is disposed on the air inlet elbow body, one end of the oil injection nozzle seat is provided with a seat hole, the other end is provided with a nozzle cap fixed plate, and a bolt hole is arranged on the nozzle cap fixed plate. Inner wall oblique holes which make way to injected sprays are arranged under the seat hole. The nozzle cap fixed plate is further provided with a limit hole, and centers of the limit hole, the seat hole and the bolt hole are on a same straight line. The air inlet elbow of the utility model effectively resolves space limitation, and guarantees installation of the oil injection nozzle without being interfered by other parts, thereby enabling engines to guarantee precise injection angle of fuel under any working conditions and further guaranteeing precise amount of fuel injection and uniform gas mixture.
Description
Technical field
The utility model relates to a kind of intake elbow of motor, specifically a kind of single-cylinder engine intake elbow that is equipped with oil nozzle.
Background technique
At present, the intelligent engine management system is widely used at automotive field, but scheme very ripe on motorcycle is less, because the useful space of foot plate bicycle own is less, arrange difficulty of injection system, and because motor is originally bigger in the vibration of operation process kind, how utilizes limited spatial arrangement injection system and guarantee strict oil spout angle, become the break-through point of realization engine intelligent management system.
The model utility content
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of single-cylinder engine intake elbow that is equipped with oil nozzle is provided.
The technical solution of the utility model is: a kind of single-cylinder engine intake elbow, comprise the intake elbow body, be provided with nozzle holder on the intake elbow body, an end of nozzle holder is provided with a hole, the other end is provided with oil nozzle cap stationary platen, is provided with bolt hole on oil nozzle cap stationary platen; Below, seat hole is provided with the inwall slope hole of stepping down for oil beam jetted, also is provided with spacing hole on oil nozzle cap stationary platen, and the center of spacing hole, seat hole and bolt hole point-blank.
The beneficial effects of the utility model are: the limitation that effectively solves the space, the installation that guarantees oil nozzle is not interfered with other component, thereby make motor under any operating mode, guarantee accurate fuel injection angle, and then guarantee accurate fuel injection quantity and uniform mixed gas.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the structural representation of the utility model seat hole inwall.
Among the figure: 1 gas bend pipe body, 2 nozzle holders, 3 holes, 4 oil nozzle cap stationary platens, 5 bolts hole, 6 inwall slope holes, 7 spacing holes.
Embodiment
As shown in the figure.
A kind of single-cylinder engine intake elbow, comprise intake elbow body 1, on intake elbow body 1, be provided with nozzle holder 2, one end of nozzle holder 2 is provided with a hole 3, seat is installed oil nozzle on the hole 3, the other end is provided with oil nozzle cap stationary platen 4, is provided with bolt hole 5 on oil nozzle cap stationary platen 4, and bolt hole 5 is used to connect the oil nozzle cap; Because seat hole 3 is downward-sloping, following inwall has obvious edges and corners, is easy to generate wet wall phenomenon, influences fuel injection quantity, and below, therefore present hole is provided with the inwall slope hole of stepping down for oil beam jetted, can avoid wet wall phenomenon; Also be provided with spacing hole 7 on oil nozzle cap stationary platen 4, the center of spacing hole 7, seat hole 3 and bolt hole 5 by sight alignment, prevents that the oil nozzle cap from rotating point-blank.
The utility model is utilizing the installation that guarantees oil nozzle under the prerequisite of the confined space not interfere with other component, utilize spacing hole 7 to prevent that the rotation of oil nozzle cap from having guaranteed fuel injection angle accurately and fuel injection quantity, realize the fuel injection work of engine management system, make motor under various operating modes, obtain the mixed gas of reasonable air fuel ratio, reduce discharging to reach, reduce characteristics such as oil consumption.
Claims (2)
1, a kind of single-cylinder engine intake elbow, comprise the intake elbow body, it is characterized in that: be provided with nozzle holder on the intake elbow body, an end of nozzle holder is provided with a hole, the other end is provided with oil nozzle and emits stationary platen, emits at oil nozzle to be provided with bolt hole on the stationary platen; Below, seat hole is provided with the inwall slope hole of stepping down for oil beam jetted.
2, single-cylinder engine intake elbow according to claim 1 is characterized in that: emit at oil nozzle also to be provided with spacing hole on the stationary platen, the center of spacing hole, seat hole and bolt hole point-blank.
