Abstract

Disclosed is an engine with oil separation and oil supply functions used for power boosting bicycle, mainly comprising a crank chamber (1), a carburetor (2), a cylinder end (3) and an engine oil pump (4). The chamber body of the crank chamber (1) is equipped with the engine oil pump (4), and one end of the engine oil pump worm rod (5) is inserted in one end of the engine driving gear shaft (6). An oil outlet mouth (7) of the engine oil pump is connected with an oil inlet mouth (9) on an air inlet pipe (8) of the carburetor. In the engine working process, the utility model realizes separating engine oil and gasoline, simultaneously self-mixing gasoline and engine oil and then supplying oil to the engine. The utility model can be directly individually added with engine oil or gasoline in filling stations at any time, and is convenient to customers.

Description

Separate the fuel feeding motor

Technical field

The utility model relates to motor, relates in particular to a kind of separation fuel feeding motor that is used for moped.

Background technique

The motor of moped before use at present, must provide blended fuel oil to motor, and this blended fuel oil is to mix lubricating oil in gasoline by a certain percentage, back injection fuel tank supply engine stirs, this usage mode is brought a lot of troubles to the user, particularly run into when going out, distance surpasses the fuel tank storage level, the user can not directly refuel toward fuel tank after having arrived the gas station, must earlier gasoline be added in the container, adds lubricating oil in the gasoline in proportion again, in the container case, stir just to inject in the fuel tank and use, complicated operation needs manually to mix, and wastes time like this.

Summary of the invention

The purpose of this utility model provides a kind of separation fuel feeding motor, and solving existing moped can not mix the back problem that adds in the fuel tank automatically with machine oil and gasoline.

In order to achieve the above object, the technical solution of the utility model is: a kind of separation fuel feeding motor, comprise crankcase, Carburetor, cylinder head, on the casing of crankcase, oil pump is installed, wherein oil pump worm screw one end embeds in the end of motor driving gear shaft, and the oil outlet of oil pump communicates with oil intake nozzle on the carburetor air pipe by oil pipe.

This programme is equipped with oil pump on the casing of crankcase, oil pump worm screw one end stretches in the left crankcase of motor, connect with the motor driving gear shaft, make oil pump and simultaneous firing, when the motor driving gear shaft rotates, driving the oil pump worm screw rotates, oil pump is started working, oil inlet pipe is with in the machine oil inhalation machine oil pump, because the oil outlet of oil pump communicates with oil intake nozzle on the carburetor air pipe by oil pipe, machine oil is delivered in the suction tude of Carburetor by the oil outlet of oil pump like this, the machine oil that enters in the suction tude of engine and carburetor mixes with gasoline in the former engine and carburetor, atomizing, enter the firing chamber oil lubricating again, gasoline combustion, like this in engine working process, machine oil and gasoline separately are mixed into the firing chamber in 1: 50 ratio simultaneously automatically, supply engine in the fuel tank that reinjects after need be before not providing fuel oil to motor with container gasoline and lubricating oil not being mixed.

The utility model has the advantages that: in engine working process, realize machine oil and gasoline separately, simultaneously automatically behind blend gasoline and the machine oil to engine oil, and all can directly add machine oil or gasoline separately in the gas station at any time, make things convenient for the user.

Description of drawings

Accompanying drawings is further detailed the utility model

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the worm screw 5 of oil pump 4 in the utility model and the annexation figure of motor driving gear shaft 6.

Embodiment

The structure that the utility model separates the fuel feeding motor is as shown in Figure 1 and Figure 2: mainly be made of crankcase 1, Carburetor 2, cylinder head 3, oil pump 4, oil pump 4 wherein is installed on the casing of crankcase 1, wherein oil pump worm screw 5 one ends embed in the end of motor driving gear shaft 6, and the oil outlet 7 of oil pump communicates with oil intake nozzle 9 on the carburetor air pipe 8 by oil pipe.

On each car, except that being installed, petrol tank also sets up a lubricating oil case, when engines gear shaft rotates, because oil pump worm screw 5 one ends embed an end transferring power of motor driving gear shaft 6, oil pump 4 work, in the machine oil inhalation machine oil pump 4 of oil pump suction tude 10 with the lubricating oil case, the oil pipe that is connected with oil intake nozzle 9 on the carburetor air pipe 8 by oil pump oil outlet 7 is delivered in the carburetor air pipe 8 again, at this moment, enter that gasoline in machine oil and the engine and carburetor 2 in the engine and carburetor 2 mixes, atomizing enters the firing chamber.

Claims

1, a kind of separation fuel feeding motor, comprise crankcase (1), Carburetor (2), cylinder head (3), it is characterized in that: oil pump (4) is installed on the casing of crankcase (1), wherein oil pump worm screw (5) one ends embed in the end of motor driving gear shafts (6), and the oil outlet of oil pump (7) communicates with oil intake nozzle (9) on the carburetor air pipe (8) by oil pipe.
