摘要： Es werden ein Verfahren und eine Vorrichtung zur Erkennung einer Leckage in einem Kraftstoffversorgungssystem einer Brennkraftmaschine, insbesondere einer Brennkraftmaschine mit einem Common Rail System, beschrieben. Eine steuerbare Pumpe fördert Kraftstoff in einen Speicher. Ein Drucksensor erfaßt den Druck in dem Speicher. Zur Erkennung einer Leckage wird im Schubbetrieb ein Ansteuersignal der Pumpe mit wenigstens einem Schwellwert verglichen und/oder es wird überprüft, ob der Druck wie erwartet abfällt.

摘要： The description relates to a device for detecting a leak in a fuel supply system in an internal combustion engine and especially a diesel engine, in which fuel is supplied to the injection valves at high pressure. The fuel pressure is constantly measured and controled in the usual way by a regulating circuit in that a magnetic valve in the fuel return is suitably operated. If the control device detects the existence of a predeterminable state, e.g. thrust operation, the magnetic valve (24) is closed and the pressure change arising is checked to see whether it changes or whether the pressure rises in the predeterminable manner. If not, a leak is detected and the fuel supply is cut off.

摘要： A system and method for detecting an air leak within an exhaust system (40,52) is provided. The method includes measuring an exhaust gas constituent in exhaust gases from an engine (12) when the engine (12) is operating in an idle operating mode and further includes determining whether the air leak is present in the exhaust system (40,52) based on a measured exhaust gas constituent, a first air-fuel correction value, and a second air-fuel correction value.

摘要： A marine engine includes an exhaust manifold, a valve cover (41), a top cover (10), and a fuel supply pipe (33). The exhaust manifold collects exhaust gases discharged from a plurality of cylinders. The valve cover (41) is a cover that covers all of a plurality of valves for air intake or air discharge to or from the cylinders. The top cover (10) is a cover that covers the valve cover (41). The fuel supply pipe (33) is arranged in a space between the valve cover (41) and the top cover (10), and allows a fuel to flow therethrough. The top cover (10) is provided with a partition (11) that is arranged so as to separate the side where the exhaust gas flows immediately after being discharged from the exhaust manifold from the side where the fuel supply pipe (33) is arranged.
