Patent number: 9541047Abstract: A system, which is used in particular as a fuel injection system for the high-pressure injection in internal combustion engines, includes a fuel distributor and a plurality of fuel injectors. Each fuel injector is situated on a cup of the fuel distributor. At least one of the fuel injectors is fastened to the associated cup by a holding element, which has a supporting surface. The cup has a contact surface on an underside, by way of which the cup is supported at the supporting surface of the holding element by a damping layer. The holding element is attached to the cup. In addition, the fuel injector has a collar, which is braced on the holding element. Because of the damping layer, vibrations are able to be dampened, and the noise transmissions is able to be reduced.Type: GrantFiled: April 2, 2013Date of Patent: January 10, 2017Assignee: Robert Bosch GmbHInventors: Jens Pohlmann, Michael Fischer, Martin Riemer, Markus Friedrich, Andreas Rehwald, Michael Mayer, Dietmar Uhlenbrock, Matthias Maess, Goekhan Guengoer, Venkatesh Kannan

Publication number: 20150059703Abstract: An insulating element for a fuel injection apparatus is notable in particular for the fact that a low-noise design is achieved. The fuel injection apparatus encompasses at least one fuel injection valve and one receiving bore in a cylinder head for the fuel injection valve, and the insulating element between a valve housing of the fuel injection valve and a wall of the receiving bore. The insulating element possesses an inner insulating ring that is present in encapsulated fashion between an outer ring and an inner ring. The outer ring is directed toward the fuel injection valve and the inner ring is directed toward the wall of the receiving bore, so that corresponding abutment of these components occurs with the insulating element in the installed state. The fuel injection apparatus is suitable in particular for direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignited internal combustion engine.Type: ApplicationFiled: March 22, 2013Publication date: March 5, 2015Applicant: ROBERT BOSCH GMBHInventors: Martin Kochanowski, Thomas Froehner, Markus Friedrich, Martin Scheffel, Jason Kramer
