Abstract: An internal combustion engine including a cylinder head, a fresh air duct configured for providing a fresh air supply to the internal combustion engine, and a quick-closing valve arranged in the fresh air duct, upstream of the cylinder head of the internal combustion engine, in order to interrupt the fresh air supply. The internal combustion engine also includes an exhaust gas recirculation pipe that has an outlet opening that is arranged centrally in the fresh air duct and, in a flow direction of the fresh air supply, upstream of the quick-closing valve forming a minimum gap between the outlet opening and the quick-closing valve.

Abstract: An oil filler neck assembly is provided for an internal-combustion engine, which includes a hinged lid and a lock. The lock, in turn, includes a rotating device and a fixing device. The rotating device is rotatably arranged in the lid. The fixing device is arranged in an oil feed opening. The lock can also be used at poorly accessible locations and causes a high sealing force.

Abstract: The invention relates to a fuel injection system for an internal combustion engine, specially a diesel engine, comprising a crankcase and cylinder heads. Said system is provided with injectors to inject fuel into the combustion chambers of the internal combustion engine and a high pressure pump which supplies fuel to a common rail supplying fuel to the injectors via high pressure lines. According to the invention, the common rail is lodged in or on the walls of the crankcase. This arrangement of the common rail track and preferably also that of the fuel injectors and the high pressure lines in the housing of the internal combustion engine optimally protects the fuel injection system from external influence and damages while at the same time hermetically closing it from the outside by forming an internal leakage chamber.
