As for an opening/ closing timing of the reservoir chamber valve 16, an opening/closing operation is carried out twice per cycle. The first opening/closing operation is carried out in an expansion stroke, and a part of the high pressure burnt gas in the combustion chamber is taken in the reservoir chamber. The second opening/closing operation is carried out in a compression stroke after an air intake valve 7 is closed, and the high pressure burnt gas in the reservoir chamber is discharged to the combustion chamber. When the burnt gas is taken in, or when it is reserved in the reservoir chamber, and further when it is discharged to the combustion chamber, the burnt gas is cooled. Thereby, the cooled EGR gas is inputted to the combustion chamber.

Title: Method and system for detecting salinity
Inventor: MURAYAMA TAKESHI
IPC: G01N30/02
Filed: 1992-12-22
Abstract: PURPOSE:To detect leakage of sea water quickly, positively, and automatically by measuring the acid conductivity while switching an ultrapure water, a standard liquid, and a sample liquid, and measuring the ion concentration of chloride when the acid conductivity of the sample liquid exceeds a set level. CONSTITUTION:A conductivity detector 18 measures the conductivity of ultrapure water 2, at first. Since the ultrapure water 2 initially contains neither cation seed nor anion seed, a signal from the detector 18 passes through a membrane from the outside to the inside of a cation exchange tube thus exhibiting the conductivity of a base line caused by the migration of sulfuric acid in a removed liquid according to the concentration gradient. A standard liquid 3 has a specific acid conductivity and employed for determining a calibration curve basing on the increase of acid conductivity from the base line. When the conductivity of the sample liquid 1 exceeds a preset level, an ion chromatography measures chloride ions in the sample liquid 1 thus deciding whether leakage of sea water caused increase of conductivity of the sample liquid 1.
