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： An ion current detector for detecting an ion current generated by combustion ions which are created by the application of a voltage has a positive electrode (2,3) and a negative electrode. The latter is located so that it lies opposite the positive electrode with a gap (9) between them so as to generate the combustion ions in this gap by the application of a voltage between the electrodes. The negative electrode comprises a semiconducting component (21) to generate a free electron coupled to the combustion ions when a voltage is applied between the electrodes. The semiconducting component is located on an outer surface of the electrode.
