The width of a wide part of the first stepped part is less than the width of a narrow part of the second stepped part. The width of the wide part of the first stepped part is less than the width of a portion, of the inner surface of the attachment concavity, that faces the wide part of the first stepped part.

Abstract: Methods and systems are provided for supplying cooling oil to a piston of an engine cylinder. In one example, a method may include repeatedly activating an oil supply only during a part of a cylinder cycle synchronous with a reciprocating motion of the piston. In particular, supply of cooling oil may be initiated by displacing a poppet valve arranged within a piston cooling assembly via a reciprocating motion of the piston.

Abstract: An internal combustion engine, which can improve an annual energy consumption efficiency, is provided. A gas engine 1 includes: an oil cooler 11 having a passage via which heat is exchanged between engine cooling water and lubricating oil; and a control unit 12 configured to control a temperature of the engine cooling water to a constant temperature so as to cool the lubricating oil during high load operation and to heat the lubricating oil during low to medium load operation. The control unit 12 increases the temperature of the engine cooling water during low to medium load operation compared with the temperature of the engine cooling water during high load operation. An oil jet 18a, which is configured to inject the lubricating oil into a rear surface of a piston 17, is provided.

Abstract: One example method includes varying oil injection by an oil injector onto a piston of an engine to accommodate different operating conditions. For example, by adjusting oil injection, suitable cooling effects can be provided without providing additional oil that increases the amount of oil deposits in the engine. In this way, the risk of pre-ignition can be reduced.
