13532247156 BMW SEAL RING

The BMW SEAL RING is an essential part used in the fuel injector of select BMW models such as the 535d, 535dxi, and 740ldxi. Located within the Engine Parts > Fuel Supply > Fuel Injector category, this seal ring offers technical advantages by providing a secure fit and preventing leaks between components, thus safeguarding engine integrity and performance. Fuel injectors are electronically controlled valves that deliver precisely metered amounts of fuel into an engine’s intake manifold or directly into the combustion chamber. These components utilize solenoid-activated needles to atomize fuel under high pressure, optimizing air-fuel mixture for combustion. Injectors are specified by flow rate (cc/min) and spray pattern, critical for engine performance and emissions control. Modern injectors incorporate multi-hole nozzle designs and are often integrated with sealed O-rings and retaining clips for leak-proof installation. Failure modes typically involve clogging, electrical faults, or mechanical wear affecting fuel delivery volume and consistency.
