    摘要： An impurity derived from a high-molecular-weight polyethylene glycol compound is removed from a high-molecular-weight polyethylene glycol compound whose total average number of moles of ethylene oxide units added in the molecule is 220 to 4500. In a state where the high-molecular-weight polyethylene glycol compound is dissolved in at least one of water and an organic solvent selected from aromatic hydrocarbon solvents having 8 or less carbon atoms in total and ester compound solvents having 5 or less carbon atoms in total, the water and the organic solvent are mixed. The resulting mixture was separated into an organic layer and an aqueous layer, and the organic layer is separated from the aqueous layer.

    摘要： An in-cylinder pressure detection device for an internal combustion engine, which is capable of calculating a hysteresis amount properly to thereby detect in-cylinder pressure with high accuracy. The in-cylinder pressure detection device comprises an in-cylinder pressure sensor that detects in-cylinder pressure as a detected in-cylinder pressure. The in-cylinder pressure detection device estimates an in-cylinder pressure generated when combustion is not performed in the cylinder, as a motoring pressure, calculates a hysteresis amount indicative of a difference between the detected in-cylinder pressure and an actual in-cylinder pressure, based on the detected in-cylinder pressure and the motoring pressure obtained during the exhaust stroke of the engine, and corrects the detected in-cylinder pressure based on the calculated hysteresis amount.
