Biodiesel fuel engine system and method of driving biodiesel fuel engine

Abstract

Provided is a biodiesel fuel engine system by which a biomass fuel for existing diesel engines can be produced from liquid biomass resources containing fats and oils originating in plants or animals without resorting to a reforming treatment by the methyl ester method and which can be stably driven at a low fuel cost and a high reliability; and a method of driving a biodiesel fuel engine. [MEANS FOR SOLVING PROBLEMS] As a liquid fuel stock, use is made of liquid biomass resources containing fats and oils originating in plants or animals. After adding a surfactant, the liquid fuel stock is divided into microparticles having a diameter of 10 [mu]m or less by a miniaturization device (1) to give a biomass fuel. Next, the biomass fuel is supplied via a biomass fuel feeding system (50) into a fuel jetting device (51). From the fuel jetting device, the biomass fuel is sprayed into an engine cylinder (52) to thereby drive the diesel engine (53).

Description

technical field [0001] The present invention relates to a bioenergy fuel for diesel engines that can be produced from liquid biomass resources containing fats and oils derived from animals and plants without the need for a modification treatment by the methyl ester method, thereby enabling low-burning A highly reliable and stable biodiesel fuel engine system and a method for operating the biodiesel fuel engine are provided. Background technique [0002] Patent Document 1 or Patent Document 2 discloses a technique of using animal and vegetable oil as a fuel for cooking with a burner. On the other hand, in recent years, biodiesel fuel (BDF) has attracted attention as a fuel for diesel engines. This biodiesel fuel is converted into fuel by reforming animal and vegetable oils by the methyl ester method. Lowering the ignition point of animal and vegetable oils through the methyl ester method, or lowering the kinematic viscosity, and improving fuel injection characteristics, can...

AI Technical Summary

Problems solved by technology

[0006] (1) Chemically react animal and vegetable oils with methanol to turn them into fuels. The cost of upgrading treatment, including the cost of equipment required for upgrading treatment, is high and more expensive than light oil

[0007] (2) Glycerin is produced as a by-product, and its treatment requires labor and cost

[0008] (3) Due to the deglycerin treatment, the heat of the obtained biodiesel fuel is small, and high output cannot be obtained

[0009] (4) When 100% biodiesel fuel is used without mixing light oil and other mineral fuels, since there is no lubricating substance, it is easy to cause mechanical damage such as burning and sticking in the diesel engine, and the reliability is low
