Better for sealing effect, the connecting end that described empty filter connecting tube connects empty filter is provided with seal groove, and described seal groove is provided with the O RunddichtringO,
In order to reduce engine exhaust emission, empty filter connecting tube is provided with labyrinth flue gas leading attachment hole, and described labyrinth flue gas leading attachment hole is connected with casing waste gas labyrinth by pipeline.
In order to limit the position of the oil pipe pipeline that is connected with Carburetor, empty filter connecting tube is provided with the oil inlet pipe limiting board, and described oil inlet pipe limiting board is two.
For weight reduction, described empty filter connecting tube and intake elbow are working of plastics.
Owing to adopted technique scheme, the utlity model has following advantage:
1. adopt empty filter connecting tube and intake elbow, increased air inlet length, air inlet inertia is increased, and help the raising of low-speed performance in the motor;
2. link to each other by intake elbow between Carburetor and the engine inlets, reduced intake resistance, seal groove and O RunddichtringO are set on the intake elbow, guaranteed sealing effect;
3. adopt intake elbow between Carburetor and the engine inlets, not only make Carburetor more near body, structure is compact more, but also has played good effect of heat insulation;
4. empty filter vertically is provided with, and the complete machine width is reduced greatly, and for convenience detach and maintenance, has reduced packing cost and cost of transportation;
5. empty filter connecting tube and intake elbow all adopt working of plastics, have alleviated complete machine weight;
In sum, the utility model has compact structure, convenient disassembly is quick, intake efficiency is high advantage.
