  • Patent number: 10787972
    Abstract: When there is a restart request to an engine, an electronic control unit controls a wastegate valve to a fully open position on condition that a speed of a vehicle is less than a threshold. When the vehicle speed is not less than the threshold, the electronic control unit restarts the engine and controls the wastegate valve in the closing direction until a desired torque is generated.

  • Patent number: 9821794
    Abstract: When a catalyst temperature is lower than a predetermined temperature on a second or subsequent start of an engine since system activation of a vehicle, a catalyst warm-up request is output for the purpose of warming up a catalyst in a catalytic converter. An output limit Wout of a battery is not increased in response to a second or subsequent output of the catalyst warm-up request, while being increased in response to a first output of the catalyst warm-up request. Accordingly, the catalyst warm-up in response to the second or subsequent output of the catalyst warm-up request since the system activation suppresses excessive output of electric power from the battery and thereby suppresses deterioration of the battery. Catalyst warm-up is performed in response to the second or subsequent output of the catalyst warm-up request. This suppresses deterioration of emission.

  • Patent number: 9032707
    Abstract: A diesel exhaust gas collection and treatment system for collecting exhaust gas from a diesel engine powered vehicle, treating the exhaust gas with injected ambient air, then releasing the air and exhaust gas mixture to the atmosphere features a vehicle powered by a diesel engine. A stream of exhaust gas from operation of the diesel engine flows through an exhaust manifold into a generally tubular exhaust collector via an exhaust inlet port. A plurality of ambient air injection ports is located on a posterior collector end, each having an ambient air injection tube connected to a corresponding air injection port. The exhaust collector features a plurality of collector outlet ports located on the exhaust collector side wall, each having a collector outlet pipe located on and fluidly connected to a corresponding collector outlet port. The exhaust collector is flexibly suspended underneath a vehicle.

  • Publication number: 20150121851
    Abstract: Systems, methods and techniques for exhaust gas recirculation are provided. The system includes controlling the mixing of exhaust flow from at least one cylinder of an engine with air in an air intake system prior to combustion in response to an EGR fraction deviation condition. The exhaust flow from the at least one cylinder is accumulated prior to mixing and distributed into the intake air system in a controlled manner to mitigate or prevent the EGR flow from deviating from an expected EGR fraction.

  • Publication number: 20150121847
    Abstract: Embodiments for heating a vehicle cabin are disclosed. In one example, a method for heating a vehicle cabin comprises closing an exhaust throttle while diverting at least a portion of throttled exhaust gas through an exhaust gas recirculation (EGR) cooler coupled upstream of the throttle, and transferring heat from the EGR cooler to a heater core configured to provide heat to the vehicle cabin. In this way, exhaust heat may be directly routed to the cabin heating system.

  • Publication number: 20150121846
    Abstract: The invention relates to a system for recovering energy from an exhaust gas circuit (3) of a heat engine (1), including an exhaust gas by-pass pipe (12) that includes a heat exchanger with two compartments, and has a first manifold (14) leading into one compartment (16) and a second manifold (15) leading into the other compartment (17), said system comprising a first valve (18) installed in the exhaust circuit (3) and capable of controlling the flow of gases into each of said manifolds (14, 15), and a second valve (20) intended to control the flow of gases at the outlet of the heat exchanger (13). The main technical feature of a system for recovering energy according to the invention is that the first valve (18) can only be used in two positions, a first position wherein same seals the first manifold (14), and a second position wherein same seals the exhaust circuit (3) and only allows the exhaunt gases to flow into the first manifold (14).

  • Patent number: 9021805
    Abstract: Methods and systems are disclosed for controlling an exhaust gas recirculation valve in an engine by determining errors in exhaust backpressure estimates and adapting EGR flow estimations based on these errors to meet target EGR dilutions in the engine. In one example approach, a method comprises adjusting valve position based on desired EGR flow and estimated EGR flow, where the estimated flow is based on estimated exhaust backpressure, and the estimated exhaust backpressure is updated based on errors between actual and desired intake oxygen concentration.

  • Publication number: 20150113961
    Abstract: An engine system for treating nitrogen oxides present in an exhaust gas generated by the combustion of fuel. The engine system includes one or more long breathing lean nitrogen oxide traps that is/are configured to store at least a portion of the nitrogen oxide in the exhaust gas when the lean nitrogen oxide trap operates in an absorption mode. The lean nitrogen oxide trap is also configured for the conversion of the nitrates stored by the lean nitrogen oxide trap during a regeneration event. The engine-out nitrogen oxide levels may be reduced to extend the duration of the absorption process, thereby reducing both the frequency of regeneration events and the associated fuel penalty. The system may include primary and secondary exhaust gas recirculation systems, with exhaust gas from the secondary system being returned to the engine cylinder to reduce the level of nitrogen oxides in that exhaust gas.
