Stand-alone tri-oil-pump diesel engine

Abstract

The invention provides a stand-alone tri-oil-pump diesel engine. Three oil pumps which are connected with a three-way oil supply pipe are arranged on the diesel engine; an oil pump tappet and an idler wheel are arranged at the other side of each oil pump; a cam shaft gear is arranged at one end of a cam shaft; the other side of a tappet plate is in contact connection with a concave-convex shaft; a concave-convex gap is arranged on the concave-convex gap; the concave-convex shaft is arranged on a concave-convex shaft gear and meshed and connected with an adjusting gear; the adjusting gear is arranged on a shaft of an adjusting and positioning wheel; one side of the shaft if the adjusting and positioning wheel is provided with a positioning wheel which is provided with a positioning groove;and one side of an installing shaft of the adjusting gear and the positioning wheel is connected with an adjusting handle through a stay cord. Because the oil pumps with different oil supply amounts are arranged on the diesel engine and are used for outputting output power corresponding to the oil supply amounts, therefore oil can be saved by more than 30 percent; and the invention has the characteristics of oil saving, environment friendliness, carbon emission reduction, economic investment saving and convenience for use and is suitable for being applied to diesel engines in power-variable application occasions.

Description

technical field [0001] The invention proposes an improved type of diesel engine in the field of power machinery, specifically a single-machine three-oil-pump diesel engine. Background technique [0002] Before the present invention was proposed, the output power of ordinary diesel engines had a rated value, and the size of the output power was adjusted by the oil intake of the accelerator. Yes, a rated output diesel engine has an oil pump, so there is no dedicated fuel quantity control to operate when the required output changes. For example, when a diesel engine with a rated output power of 14.7 kilowatts is used for pumping water, it will output at a rated power of 14.7 kilowatts, and when it is used for spraying chemicals on farmland, it will need 4.3 kilowatts. It runs at low power, so it consumes a lot of oil and is uneconomical to use. Therefore, a farmer needs to be equipped with several diesel engines with different powers.

[0002] Before the present invention was proposed, the output power of ordinary diesel engines had a rated value, and the size of the output power was adjusted by the oil intake of the accelerator. Yes, a rated output diesel engine has an oil pump, so there is no dedicated fuel quantity control to operate when the required output changes

For example, when a diesel engine with a rated output power of 14.7 kilowatts is used for pumping water, it will output at a rated power of 14.7 kilowatts, and when it is used for spraying chemicals on farmland, it will need 4.3 kilowatts. It runs at low power, so it consumes a lot of oil and is uneconomical to use. Therefore, a farmer needs to be equipped with several diesel engines with different power

[0003] According to the actual use of diesel engines and the structural characteristics of existing diesel engines, there are disadvantages such as difficult to accurately control the output power adjustment, large oil consumption and inconvenient use
