Sliding rod type switch for fuel machine

Abstract

The invention belongs to the field of engines and relates to a sliding rod type switch for a fuel machine. An oil inlet hole and an oil outlet hole are oppositely formed in the side wall of a containing groove. A gas inlet hole and a gas outlet hole are oppositely formed in the side wall of the containing tank. The center connecting line of the oil inlet hole and the oil outlet hole and the center connecting line of the gas inlet hole and the gas outlet hole are not in the same horizontal plane. The sliding rod type switch further comprises a control rod matched with the containing groove. The control rod is slidably arranged on the side wall of the containing tank. An oil groove capable of connecting the oil inlet hole with the oil outlet hole and a gas groove capable of connecting the gas inlet hole with the gas outlet hole are arranged on the control rod. The distance between the center connecting line of the oil inlet hole and the oil outlet hole and the center connecting line of the gas inlet hole and the gas outlet hole is greater than the distance between the oil groove and the gas groove, and a cover plate is fixed to the end face of a switch seat and seals a tank opening of the containing tank. In this way, mixed combustion of oil and gas is avoided, and accordingly an engine is protected.

Description

technical field [0001] The invention belongs to the field of engines and relates to a slide bar switch of a fuel engine. Background technique [0002] At present, domestically produced gasoline engines all use fuel oil as the power source, causing heavy pollution and high fuel consumption. With the rise of oil prices and the improvement of environmental protection requirements, single-fuel gasoline engines have become less and less suitable for the requirements of social development. CNG is short for Compressed Natural Gas. CNG is a non-toxic, odorless, colorless gas with low price, no carcinogens such as benzene, lead, sulfur (exhaust pollution is 1 / 3 of gasoline), and no carbon deposits in the working area, no dilution of engine oil, and no engine wear Small (can save 50% of engine oil costs), abundant reserves, easy storage and transportation, etc., it is the most ideal gasoline substitute at present. Although the gasoline engine that uses CNG as fuel can solve the pro...

Problems solved by technology

The purpose of the present invention is to ensure that only one kind of fuel enters the carburetor through the switch base at any time, so as to prevent the mixed combustion of oil and gas in the engine. The oil is brought into the gas pipeline, on the contrary, during the process of converting from gas to oil, the gas will also be brought into the oil pipeline, and there will still be a problem of mixed combustion, and each conversion will mix, causing damage to the engine , affect the use of the engine, and even affect the performance and life of the engine
