摘要： PROBLEM TO BE SOLVED: To further reduce a frictional force of a piston in a cylinder piston mechanism. SOLUTION: A skirt portion 18 of a piston 14 has a cross-sectional shape profile within a plane perpendicular to an axial direction being substantially the same along the axial direction. The cross-sectional shape profile includes: a central region having a predetermined central ellipticity defined beforehand, in a range of a predefined central region length B in a portion in a thrust direction and anti-thrust direction relative to a cylinder bore 12; both side regions having a both sides portion ellipticity larger than central ellipticity, in ranges of both sides of the central regions; and a connection region in which the central region and the both side regions are connected, a clearance with an inner diameter of a cylinder bore 12 has a central connection portion clearance defined beforehand in a connection point with the central region, a clearance from the inner diameter of the cylinder bore 12 has a both sides connection portion clearance C1 defined beforehand in a connection point with the both side regions.

摘要： PROBLEM TO BE SOLVED: To provide a means to effect accurate detection of abnormality of a fuel injection system even when a fuel pressure is fluctuated in a wide range. SOLUTION: High pressure fuel is fed with a pressure from a high pressure fuel injection pump 5 to a common rail 3 and fuel is fed to each fuel injection valve 1 from the common rail. A control circuit (ECU) 20 detects a common rail pressure by a fuel pressure sensor 31 and calculates pressure fluctuation actual measurement values before and after injection of fuel and pressure fluctuation actual measurement values before and after the forced feed of fuel. Further, the ECU 20 calculates presser fluctuation estimated values before and after injection of fuel and pressure fluctuation estimated values before and after the forced feed of fuel based on a fuel injection command value and a fuel force feed amount command value. Further, the ECU 20 calculates a first abnormal decision amount from an actual measurement value and pressure fluctuation estimated values before and after injection of fuel and a second abnormality decision amount from an actual measurement value and pressure fluctuation estimated values before and after injection of fuel, respectively and decides the occurrence of abnormality to a fuel injection system by using both first and second abnormality decision amounts.
