摘要： PROBLEM TO BE SOLVED: To evaluate an injector deposit sideways and evaluate it in a short term. SOLUTION: At first gasoline oxidized by an oxygen atmosphere pressurization device 5 in the vessel 4 lift at a normal temperature is injected from an injector 1 as the evaluation order of an injector deposit. Thereafter, NOx gas is supplied into the vessel 4 through the piping 11 for supplying NOx and also an injector tip temperature is risen by turning a panel heater 9 on. Meantime, a gasoline oxide and NOx gas are reacted and polymerized and the injector deposit is produced. Thereafter, the ventilation in the vessel 4 and the normal temperature cooling of the injector 1 are carried out and the physical deformation of the injector deposit is reproduced. After the normal temperature cooling of the injector 1, the gasoline injection by the injector 1 is resumed. Namely, this cycle is repeatedly carried out by making a series of process to one cycle.

摘要： PROBLEM TO BE SOLVED: To maintain excellent controllability of an injection valve by preventing accumulation of a deposit, and preventing a change with the lapse of time of a fuel injection characteristic such as reduction in an injection quantity in a fuel injection valve. SOLUTION: A circular recess 18 and a radial directional fuel releasing groove 19 connected to the recess are formed by surrounding a fuel nozzle port 12 arranged in a nozzle plate 17. A hollow cylindrical cover 14 is installed around the nozzle plate 17. Since droplet-like fuel sticking to a peripheral part of the fuel nozzle port 12 is sucked and gathered to a corner part 18a by suction force by surface tension acting on the corner part 18a formed of a level difference around the circular recess 18 and is discharged in the radial direction by passing through the fuel releasing groove 19, the fuel does not remain just near the fuel nozzle port 12 so as to prevent residual fuel from accumulating in the vicinity of the fuel nozzle port 12 as a solid deposit by deteriorating at a high temperature after stopping operation.

摘要： PROBLEM TO BE SOLVED: To properly determine a performance change of a fuel pump caused by the formation of a fuel film between a brush of a brush motor and a commutator.SOLUTION: An operation period in a low-load state of the brush motor 10 in the fuel pump 9, or an operation period in a low driving voltage of the motor 10 is integrated, so that the performance change of the fuel pump 9 is determined based on an obtained integration value. As the contact surface of the brush with the commutator is highly likely to be smooth under the low-load state of the brush motor 10, the fuel film is often formed between the contact surface, which causes the deterioration of the performance (fuel ejection efficiency) of the fuel pump 9 due to the formation of the fuel film. Accordingly, the performance change of the fuel pump 9 is properly determined due to the formation of the fuel film on the contact surface between the brush of the brush motor 10 and commutator based on the integrated value.
