20220243630 | CATALYTIC CONVERTER - A catalytic converter includes at least one heating element that is configured to disrupt the direction of flow of exhaust gases which contain harmful toxic gases and pollutants and aid in removing and/or reducing said toxic gases and pollutants. | 2022-08-04 |
20220243631 | ALTERNATOR MODULATION FOR CONTROL OF EXHAUST HEATING ELEMENT - Systems and methods for modulating power provided to a heating element of a vehicle exhaust system is provided. One system includes a controller controlling a switch, and an alternator having a first field terminal input, wherein the first field terminal input is connected to the switch. The system further includes a heating element connected to at least an output of the alternator. The controller is configured to determine a power demand for the electric heating element and modulate the first field terminal input to cause the alternator to provide power to the heating element according to the power demand. | 2022-08-04 |
20220243632 | Heating Device for an Exhaust System of an Internal Combustion Engine - 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 an injection point of the fuel injector; and a spark plug, which is mounted through a side wall of the tubular body. The feeding channel is delimited, on the outside, by an outer tubular body. The fuel injector is configured to spray at least part of the fuel against the outer tubular body, which has a through opening, through which a spray tip of the fuel injector letting out the fuel directly aims at the electrodes of the spark plug. | 2022-08-04 |
20220243633 | Heating Device for an Exhaust System of an Internal Combustion Engine - 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. | 2022-08-04 |
20220243634 | ADDITIVELY MANUFACTURED CATALYTIC CONVERTER SUBSTRATES - A catalytic converter includes a catalyst substrate including a body having a length and defining a plurality of zones along the length, with each zone having at least one cross-sectional structure defining a plurality of cells forming an exhaust gas flow path through the length via cells of adjacent zones, and the cells being more densely arranged within the at least one cross-sectional structure of an upstream zone than an adjacent downstream zone. The catalytic converter also includes a wash-coat layer deposited on surfaces of the cells forming active surface area configured to react with exhaust gas traveling along the length. The exhaust gas flows along the exhaust gas flow path through the cells such that more active surface area is available for reaction in each upstream zone than an adjacent downstream zone. | 2022-08-04 |
