摘要： PROBLEM TO BE SOLVED: To provide a light oil lubricity measurement device with which lubricity of light oil is accurately evaluated for a fuel jetting pump of complex friction configuration. SOLUTION: A light oil lubricity measurement device 1 comprises a housing 4 provided with a light oil lubricity measurement space 2 where light oil is supplied, a rotation stage 6 which, positioned at the light oil lubricity measurement space 2, is allowed for rotation and a supporting stage 22 assigned to face the rotation stage 6. On the side facing the supporting stage 22 of the rotation stage 6, a test piece 32 is attached and rationally driven. On the supporting stage 22, a plurality of test rollers 42 are set. Each test roller 42 is, by moving the supporting stage 22 toward the rotation stage 6, pressurized to the rotating test piece 32 under a specified pressure.

摘要： PURPOSE:To prevent wax in fuel from blocking a fuel filter even at a low temperature without a fuel heating means in a fuel filter blockage preventive device for Diesel engine. CONSTITUTION:A control part 13 and a temperature sensor 32 are provided on a bottom part of a filter main body 10. A rotary part 31 is arranged inside a reservoir chamber 30 which is an inner space of a cylindrical part 14c of a filter element 14 installed inside the filter main body 10. The control part 31 inputs a signal output from the temperature sensor 32 and rotates the rotary part 31 when a temperature of a fuel in the filter main body 10 is not more than a paraffin precipitation temperature of the fuel. The fuel is agitated by the rotary part 31 and crystal of precipitated paraffin is broken, so that growth of wax is and blockage of a fuel filter 4 are prevented.

摘要： PURPOSE:To simplify and miniaturize the structure of the water-in fuel removal apparatus as well as to effect simultaneous performance of both detection and removal of water mixed into the fuel. CONSTITUTION:A vessel 3 of a contained-water removal device 1 is disposed in a midway position of a fuel piping 2 so that a fuel F may be allowed to stay temporarily. Within the vessel 3, the followings are disposed: an alkali- metal made contained-water removal member 12 capable of reacting with water in fuel F to produce hydroxide, and a filter 14 for separating the hydroxide from the fuel F so as to check the outflow of the hydroxide to a side downstream from the vessel 3. When the contained-water remover reacts with the water, generation of heat follows. A temperature sensor 15 for sensing the temperature of a surface of the contained water removal member 12 is mounted to the vessel 3. A controller 16 determines a temperature gradient on the basis of the temperature detected by the temperature sensor 15 and, when that temperature gradient is equal to or greater than a specified value, generates an output signal for lighting an alarm-warning lamp.

摘要： PURPOSE:To prevent blocking of a fuel filter due to generation of wax in diesel fuel at a low temperature and prevent deficient fuel supply at the time of starting at a low temperature without using a means such as an electric heater, so as to enhance startability of a diesel engine. CONSTITUTION:A fuel supply device is provided with a fuel passage 13 at the time of cold starting for directly supplying excessive fuel of a relatively high temperature from a fuel tank 1 to a fuel injection pump 2 through a filter 3; and a fuel passage 15 after starting for supplying the excessive fuel, which is mixed with low temperature fuel from the fuel tank 1, to the injection pump 2 through the fuel filter 3. The passages are switched over by the use of solenoid valves 8, 9 at the time of starting of the engine and warming of the engine after the starting while the filter 3 is bypassed so as to decrease passage resistance on the fuel passage at the time of cold starting in the case of starting at a low temperature. Furthermore, fuel of a relatively high temperature is supplied from the fuel passage after the starting at the time of warming up of the engine after the starting, thereby preventing wax from being generated.
