A control method applied to a carburetor of an integrated multi-fuel outboard engine comprises the following steps:
(1) the first oil outlet is connected with a gasoline inlet pipe on the oil storage cup through a pipeline in advance; the second oil outlet is communicated with a kerosene liquid inlet pipe on the carburetor body through a pipeline;
(2) connecting the integrated dual-purpose fuel pump with an oil tank, and installing a carburetor body on an engine;
(3) when the engine is running at low speed: the atomization cavity is continuously ventilated, the air pressure is reduced due to the high-speed flow of air in the atomization cavity, a siphon principle is formed between the oil storage cup and the atomization cavity, and under the siphon action, gasoline in the oil storage cup is conveyed into the atomization cavity through the low-speed oil conveying pipe to be atomized and supplied to an engine; the integrated dual-purpose fuel pump pumps gasoline and kerosene into the oil storage cup and the oil storage cavity; at the moment, because the air introduced into the atomizing cavity is less, the kerosene is basically not only in the atomizing cavity, and only the gasoline is supplied to the engine at the moment;
when the engine is shifted from low speed to high speed: the gasoline inlet pipe is opened, the accelerator is stepped on, the ventilation speed of the atomization cavity is increased, the first rotating shaft drives the second rotating shaft to rotate through the linkage mechanism, the second rotating shaft drives the push rod to ascend, the piston block is driven to move upwards, and oil in the acceleration oil storage cavity is flushed into the atomization cavity through the acceleration oil conveying pipe under the action of the piston block; meanwhile, a kerosene liquid inlet pipe is opened, kerosene enters an atomizing cavity and is supplied to the engine together with the gasoline, and oil liquid conversion transition of the engine is realized;
when the engine runs at a high speed: the kerosene liquid inlet pipe is opened, the ventilation quantity in the atomizing cavity is increased, a large amount of kerosene is pumped out from the high-speed oil conveying pipe, and the atomized kerosene is supplied to an engine for use; at the moment, the accelerating oil storage cavity is blocked by the piston block, and a pipeline of the oil storage cup entering the accelerating oil storage cavity is blocked by the blocking steel ball, so that gasoline liquid cannot enter the accelerating oil storage cavity, and meanwhile, the low-speed oil conveying pipe can only supply a small part of gasoline to enter the atomizing cavity or does not supply gasoline basically because the pipe diameter of the low-speed oil conveying pipe is far smaller than that of the high-speed oil conveying pipe. Under the high-speed operation of the engine, as the gasoline in the oil storage cup is not basically supplied to the atomizing cavity, the oil in the oil storage cup is full, and the integrated dual-purpose fuel pump cannot pump the oil into the oil storage cup.
It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
