The pressure sensor is located closer to the nozzle hole than the pressure-accumulation vessel. A storage unit stores individual difference information obtained by an examination. The individual difference information indicates an injection characteristic of the fuel injection valve and indicates at least one of an injection response time delay between an injection start point and a time point, at which a fluctuation is caused by the start of fuel injection in detected pressure of the pressure sensor, and a parameter for calculating the injection response time delay.

Abstract: A pressure equalization system reduces or eliminates a pressure differential across supercharger rotor shaft seals. Under high boost, rotor shaft seals often fail, allowing hot compressed air into an oil lubricated space containing rotor bearings and gears (and vented to ambient pressure), reducing oil lubricating effectiveness and resulting in increased wear and failure. Under low or non boost operation, the pressure differential is reversed causing the lubricating oil to leak into the supercharger interior and accelerated rotor seal wear. The pressure equalization system includes flow restrictive seals on both rotor shafts, separated from the rotor shaft seals by vented spaces, thereby isolating the rotor shaft seals from boost or vacuum in the supercharger interior and reducing or eliminating the pressure differential across the rotor shaft seals. Maintaining close to atmospheric pressure on both sides of the rotor shaft seals during boost and vacuum operation reduces wear and failures.

The point at which the purge path branches from the negative pressure communication path is set to be at the lowest position of the negative pressure communication path to be able to collect the oil mist intruding from the crankcase.
