Embodiment Construction

[0015] An emulsified fuel supply device according to an embodiment of the present invention is, for example, figure 1 Shown is a device for supplying emulsified fuel to an engine, such as a cylinder 4 of a diesel engine 2 , via an injection pump 6 and an injection valve 8 .

[0016] In order to become an emulsified fuel, it is necessary to mix fuel such as heavy oil and water, so a fuel system and a water system are provided.

[0017] In the fuel system, fuel oil stored in a fuel tank 10 is sent to an oil circulation circuit 14 via a booster pump 12 . In the oil circulation circuit 14 , fuel oil circulates through a confluence part 16 , a pressure circulation pump 18 , a fuel heating heat source 20 , and a release valve 22 . Fuel oil is circulated by the action of pressurized circulation pump 18 . The pressurization circulation pump 18 and the fuel heating heat source 20 are controlled by a control unit 23 . Between the fuel heating heat source 20 and the release valve 22 ,...

Abstract

An emulsion fuel feeding device which can, inexpensively and without affecting the durability of the device, detect the proportion of water in an emulsion fuel which is supplied by the device. An emulsion fuel feeding device for feeding to an engine an emulsion fuel formed by mixing fuel and water, wherein the amount of the fuel supplied to the engine (2) and the speed of the engine (2) are supplied to a governor controller (80) from an engine speed detector (82) and an engine rotation commander (84). The governor controller (80) calculates the water content ratio from the amount of the fuel fed to the engine (2) and from the speed of the engine (2).

Description

technical field [0001] The present invention relates to an emulsion fuel supply device for supplying an emulsion fuel obtained by mixing fuel and water to an engine. Background technique [0002] An example of such an emulsion fuel supply device is disclosed in Patent Document 1. According to the technology of Patent Document 1, when water and fuel are mixed and supplied to the engine by an agitator, the supply amount of water is controlled so as to become a pre-commanded water addition rate. At this time, in order to calculate the water addition rate, the output of the agitator The water filling rate detection sensor is set on the side. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent No. 4208349 [0006] However, a sensor that detects the ratio of water to fuel like this water filling rate detection sensor is expensive. In addition, the agitator with this sensor installed on the output side is installed near the engin...
