Patent number: 11913366Abstract: A heating device for an exhaust system of an internal combustion engine and having: a tubular body, where a combustion chamber is obtained on the inside; a fuel injector, which is designed to inject fuel into the combustion chamber; at least one inlet opening, which can be connected to a fan so as to receive an air flow, which is directed to the combustion chamber; a feeding channel, which receives air from the inlet opening, surrounds an end portion of the fuel injector and ends with a nozzle, which is arranged around a spray tip of the fuel injector, from which fuel flows out; and a spark plug, which is mounted through a side wall of the tubular body. An axial distance, namely measured along a longitudinal axis of the tubular body, between the spray tip of the fuel injector and a longitudinal axis of the spark plug ranges from 33% to 100% of an inner diameter of the tubular body.Type: GrantFiled: December 22, 2021Date of Patent: February 27, 2024Assignee: MARELLI EUROPE S.P.A.Inventors: Marco La Sana, Emanuele Milani, Mauro Brignone, Luigi Lubrano
