060289000 | Air feed to reactor modulated or diverted by control | 7 |
20090151336 | AGING DEVICE FOR CATALYTIC CONVERTER IN VEHICLE AND METHOD THEREOF - An aging device of a catalytic converter of a vehicle simulates wear-and-tear of a catalytic converter under conditions that simulate to those of a real vehicle by injecting an oil additive or an engine oil mixture containing phosphor (P), zinc (Zn), and etc., into an engine. | 06-18-2009 |
20090282816 | Fresh Air Bypass to Cool Down Hot Exhaust in DPF Regeneration Mode at Low Vehicle Speed and Idle - An engine system includes a diesel engine having an exhaust manifold connected to the diesel engine. An exhaust passage is connected to the exhaust manifold and a diesel particulate filter is disposed in the exhaust passage. An air intake passage is provided for supplying fresh air to the diesel engine. A bypass passage is connected between the air intake passage and the exhaust passage in a location downstream of the diesel particulate filter. The bypass passage includes a bypass control valve for opening and closing the bypass passage during a diesel particulate filter regeneration cycle when the vehicle is at low speed or idle. | 11-19-2009 |
20100115929 | CURRENT LIMITING DRIVER FOR ELECTRIC AIR PUMP - The present invention relates to a secondary air supply arrangement having an actuator operably connected to an air pump for creating air flow between an inlet and outlet of the air pump. A pulse width modulated controller is operably connected to the actuator for applying a pulse width modulated voltage to the actuator. The pulse width modulated controller controls the initial in-rush electric current when the actuator is activated. | 05-13-2010 |
20130333360 | SECONDARY AIR INJECTION SYSTEM - A secondary air injection system supplying some of air introduced into an intake manifold to an exhaust manifold may include: an electric supercharger compressing air introduced through an air duct; throttle valves installed at an upstream of the intake manifold and controlling the amount of air introduced into the intake manifold by controlling the amount of air passing through the electric supercharger; secondary air valves installed on branching paths branched from intake, lines that link the electric supercharger and the throttle vales and controlling the amount of air for secondary air injection; and an injector that post-combusts exhaust gas discharged from an engine by injecting secondary air passing through the secondary air valve to a runner of the manifold. | 12-19-2013 |
20160032803 | Exhaust After-treatment System Having Low Temperature SCR Catalyst - An aftertreatment system for treating exhaust gas discharged from a combustion engine, the aftertreatment system comprising a low temperature selective-catalytic-reduction catalyst, wherein the low-temperature selective-catalytic-reduction catalyst is a mixture of catalytic metals provided on a beta-zeolite support material, the mixture of catalytic metals being at least one mixture selected from Cu and Ce, Mn and Ce, Mn and Fe, Cu and W, Mn and W, and Ce and W. | 02-04-2016 |
060290000 | Responsive to engine speed or intake manifold pressure | 2 |
20090313975 | Air supply system for a regeneration assembly - A method of initiating regeneration of a filter assembly is disclosed. The method includes determining when regeneration of a filter assembly is to be initiated. The method also includes opening a first air valve configured to permit air flow to a regeneration assembly below a predetermined flow rate and at a sufficient flow rate to achieve ignition. The method further includes detecting ignition, and after ignition, opening a second air valve configured to supply air flow to the regeneration assembly above the predetermined flow rate and at a sufficient flow rate for regeneration. | 12-24-2009 |
20100018189 | CONTROL SYSTEM OF INTERNAL COMBUSTION ENGINE - A control system of an internal combustion engine includes: a pressure detecting mechanism detecting a pressure in a gas passage which is communicated with the engine; and a controller acquiring a reference pressure as the pressure which is detected immediately after the controller is actuated, and controlling an actuator of the engine based on the reference pressure. The controller is inhibited from acquiring the reference pressure as the detected pressure when the controller is re-actuated after the controller is reset due to a factor other than a turned-off operation of an ignition switch. | 01-28-2010 |
