Abstract: A pre-chamber for a fuel injector is disclosed. The pre-chamber includes a cylindrical body member extending axially from a first end portion to a second end portion opposite to the first end portion. The pre-chamber further includes a bottom plate located proximal to the first end portion of the cylindrical body member. The pre-chamber also includes a sacrificial member extending axially outwards from the second end portion of the cylindrical body member.

Abstract: A method and system for sorting pistons with flaws is disclosed. In an embodiment, a piston with flaws is three dimensionally scanned and compared to a reference image to detect the location and geometry of the flaws. The location and geometry of the flaws are recorded and used to generate a surface condition score. The pistons are sorted based on the surface condition score being higher or lower than a set threshold value.

Abstract: A cylinder block of an engine is provided. The cylinder block includes a top deck. The cylinder block also includes a cylindrical surface defining a bore extending from the top deck along a longitudinal axis. The cylinder block includes a shoulder portion formed on the top deck. The top deck includes an abutment surface. The cylinder block further includes an insert disposed in the shoulder portion. The insert includes an outer surface adapted to fuse with the abutment surface of the shoulder portion. A predetermined force and a predetermined electric current are applied to the insert for fusing the outer surface of the insert with the abutment surface of the shoulder portion.
