Abstract: A cylinder block (10) includes an inter-bore flow passage (14) between adjacent bores (12). Each inter-bore flow passage (14) is formed by closing an opening-side groove portion (15) continuous from a cylinder block deck face and a bottom-side groove portion (16) with the use of a lid member (20) made of copper, and the lid member (20 is laser-welded to a groove wall face of the opening-side groove portion (15). Before the laser-welding, the lid member (20) has recesses (26) that are interspersed in a direction, in which a laser beam travels, at any one of connected portions at which the lid member (20 is connected to the groove wall face of the opening-side groove portion (15).

Abstract: To provide a controller that can slow down progression of deterioration of an internal combustion engine caused by repeated occurrence of LSPI. An index value of the degree of deterioration of the internal combustion engine caused by LSPI is calculated. If the index value exceeds a first threshold, when the temperature of cooling water that cools a part of the peripheral wall of a cylinder that is close to a combustion chamber is lower than a threshold temperature, and the internal combustion engine is running in a determined operational region set in a low speed and high load region, the proportion of fuel injection by an in-cylinder injection valve is reduced to increase the proportion of fuel injection by a port injection valve compared with before the index value exceeds the first threshold, thereby suppressing occurrence of LSPI.
