| 摘要 | PURPOSE:To measure the one-time quantity of injection accurately by parting atomization liquid admitted into a measurement pipe into parts of each injection of an injection valve with filler gas, and measuring the parted liquid columns. CONSTITUTION:Liquefied fuel F is charged in the flow passage 4a of the measurement pipe 4 through an injection valve 1 up to the downstream side of a gas exhaust nozzle 5. Then, a control valve 6 is operated to open a needle valve 6a and gas G flows in the flow passage 4a from the exhaust nozzle 5b because of the differential pressure between the pressure of gas sent forcibly to a gas intake 5a and the pressure in the flow passage 4a; and the operation of the valve 6 ends and a specific among of gas G is charged in the flow passage 4a. When fuel injection is started through the valve 1, fuel F of one injection moves and the charged air G is pressed to move, forming an air column G'. Thus, the fuel injection and air charging are repeated to form parted liquid columns F' and air columns G' alternately in the flow passage 4a. The air column F' corresponds to fuel for one injection of the injection valve 1 and the length of the liquid column F' is measured, calculated 11, and displayed 12. | ||||||
