Abstract: A control method of a turbocharger for a vehicle includes a cold control step of controlling, by a controller, a closing amount of a turbocharger to be a cold closing amount preset for a cold control when a vehicle condition satisfies a cold control condition, and a cold data map application step of controlling, by the controller, the closing amount of the turbocharger according to an engine condition after the cold control step, and using a cold data map having an allowable closing amount range expanded relative to an allowable closing amount range of the turbocharger in a normal data map to include the cold closing amount when the vehicle condition satisfies a cold data map application condition, and to thereby continuously change the closing amount of the turbocharger after the cold control step and prevent rapid changes in an engine RPM.

Abstract: A direct fuel injection internal combustion engine fluidly coupled to an exhaust aftertreatment system is described and includes a plurality of fluidly coupled exhaust purifying devices and an exhaust gas sensor. A method of controlling the engine includes, activating, via a heater controller, a heating element of the exhaust gas sensor in response to starting the internal combustion engine. An exhaust gas feedstream is monitored to determine a temperature of the exhaust gas sensor. Engine control to effect heating of one of the exhaust purifying devices is permitted only when a temperature of the exhaust gas sensor is greater than a threshold temperature.

Abstract: An evaporative emissions (EVAP) control system for a vehicle includes a purge pump configured to pump fuel vapor trapped in a vapor canister to an engine of the vehicle via a vapor line when engine vacuum is less than an appropriate level for delivering fuel vapor to the engine, the fuel vapor resulting from evaporation of a liquid fuel stored in a fuel tank of the engine. The EVAP control system includes a hydrocarbon (HC) sensor disposed in the vapor line and configured to measure an amount of HC in the fuel vapor pumped by the purge pump to the engine via the vapor line. The EVAP control system also includes a controller configured to, based on the measured amount of MC, control at least one of the purge pump and a purge valve to deliver a desired amount of fuel vapor to the engine.

Abstract: Where performing a main injection, and a sub-injection that injects a minute amount of fuel in a short region of driving time, a check is conducted to determine whether or not the minute amount of fuel is injected accurately. In a specific cycle at a time of cold starting when catalyst warm-up control is performed, the main injection is omitted and a checking injection corresponding to a sub-injection is performed. Injection conditions of an in-cylinder injection valve are made uniform between the checking injection and the sub-injection. A fuel amount that is actually injected from the in-cylinder injection valve in the specific cycle is calculated based on an air-fuel ratio of exhaust gas discharged from an engine and an in-cylinder air amount, and is compared with a fuel amount that theoretically should be injected from the in-cylinder injection valve.

Abstract: A vehicle includes an engine and an electric machine coupled to a transmission element. The electric machine is also selectively coupled with the engine by a clutch. The vehicle includes a belt integrated starter-generator (BISG) operatively coupled to the engine. An electronic controller includes one or more inputs adapted to receive a temperature measurement and a request to start the engine. The electronic controller is programmed to, in response to the one or more inputs receiving the request to start the engine and the temperature measurement less than a threshold temperature measurement, effect actuation of the electric machine and close the clutch to apply a first torque to the engine. The electronic controller is further programmed to, in response to an engine speed achieving an engine speed threshold, effect actuation of the BISG to apply a second torque to the engine.

Abstract: Methods and systems are provided for addressing engine cold-start emissions while an exhaust catalyst is activated. In one example, a method for improving exhaust emissions may include flowing ionized air into an engine exhaust, downstream of an exhaust catalyst, to oxidize exhaust emissions left untreated by the catalyst. The approach reduces the PM load of the exhaust as well as of a downstream particulate matter filter.

Abstract: Starting an internal combustion engine may be difficult as a consequence of the operating conditions of the engine. Even after the engine has started, it may take a long period of time for the engine to reach operating temperatures. In the present disclosure, when engine start difficulty is expected, before starting the engine a forced induction compressor arranged with the engine may be turned on to increase the engine intake air pressure before the engine is started.

Abstract: When a catalytic converter in an exhaust passage is in an un-activated state, an intake air amount is increased, as compared to when the converter is in an activated state under the same engine operation condition, and an ignition timing is retarded beyond a TDC of a compression stroke. The ignition timing is set such that a retard amount thereof from the TDC becomes larger as an external load causing a rotational resistance of an engine becomes lower. A valve opening start timing of an exhaust valve is set such that, when the external load is lower than a given reference load, the valve starts opening, before an in-cylinder pressure reaches a peak, according to combustion of an air-fuel mixture ignited at the above ignition timing, in a subsequent expansion stroke, wherein the in-cylinder pressure is based on an assumption that the valve is maintained in a valve-closed state.

Abstract: Methods and systems are provided for controlling engine operation in a hybrid vehicle, where the vehicle engine comprises one or more cylinders dedicated to recirculating exhaust to the intake manifold. In one example, if an engine load decreases below a level where dedicated exhaust gas recirculation may lead to combustion stability issues, engine load may be increased above the demanded load and the excess power used to charge a system battery, or if the battery state of charge is above a threshold, the engine may be shut down and the vehicle propelled via battery power. In this way, fuel economy and combustion stability issues may be improved, NOx emissions reduced, and costs for implementation of dedicated exhaust gas recirculation decreased.

Abstract: A method comprising adjusting a fuel injection amount based on a fractional oxidation state of a catalyst, the fractional oxidation state based on reaction rates of grouped oxidant and reductant exhaust gas species throughout a catalyst and a low-dimensional physics-based model derived from a detailed two-dimensional model to obtain a one-dimensional model averaged over time and space that accounts for diffusion limitations in the washcoat and accurately predicts emissions during cold start.
