Systems and methods for reducing heat loss to a turbocharger during cold engine starting are described. In one example, a turbocharger bypass pipe and a turbocharger turbine pipe are oriented at forty five degrees relative to a longitudinal axis of a catalyst so that a turbocharger turbine may be completely bypassed, thereby increasing the amount of energy that may be transferred to the catalyst.

Method and systems for reducing heat loss to a turbocharger during cold engine starting

Methods and systems are provided for an aftertreatment system. In one example, a system comprising a spark-ignited engine comprising a selective catalytic reduction device (SCR) arranged in an exhaust passage downstream of a catalyst, and an injector positioned to inject a reductant directly into the exhaust passage downstream of the catalyst subsequent an engine shut-off event.

Methods and systems for an aftertreatment system

The present description relates generally to methods and systems to compensate for oxygen sensor drift caused by hydrogen diffusion within the exhaust system. In one example, a method includes adjusting a fuel amount supplied to an engine based on an estimated amount of hydrogen in the reference cell of an oxygen sensor. In this way, oxygen sensor bias on sensed AFR may be corrected.

Modeling to compensate for HEGO sensor drift

Methods and systems are provided for a vehicle adapted to be operated based on fuel combustion or electric power. In one example, an accessory train of the vehicle, including an air conditioning pump and a power steering pump, may be operated according to a first mode or according to a second mode based on a power system of the vehicle. When in the second mode, the vehicle may be instructed to coordinate operation of the air conditioning pump and the power steering pump.

Automotive accessory drive train

Embodiments for controlling condensate in a charge air cooler are provided. In one example, a charge air cooler comprises an inlet to admit charge air, a plurality of heat exchange passages to remove heat from the charge air, an outlet configured to discharge the charge air from the heat exchange passages to an intake passage upstream of an intake manifold of an engine, and a dispersion element extending at least partially across the outlet.

Charge air cooler condensation dispersion element

Methods and systems are provided for operating an engine to diagnose and compensate for cylinder imbalance in an engine. In one example, a method may include diagnosing a torque imbalance in a multi-cylinder engine by operating the engine at a lean air-fuel ratio (AFR) while an amount of ammonia stored in an selective catalytic reduction (SCR) system is greater than a threshold amount and a temperature of the engine is greater than a threshold temperature; and responsive to the diagnosed torque imbalance, adjusting fueling and spark timing for each cylinder, the adjustments based on an AFR offset of each cylinder determined while adjusting the lean AFR.

Method and system for measuring and balancing cylinder air-fuel ratio

Methods and systems are provided for implementing fluid injection through a cylinder valve seat. The engine system may include a cylinder valve with a valve head mating with a valve seat when the valve is closed. The valve seat includes an injection orifice blocked by the valve head when the cylinder valve is closed and unblocked when the cylinder valve is opened.

System and method for valve seat injection

Methods and systems are provided for controlling and coordinating control of a post-catalyst exhaust throttle and an EGR valve to expedite catalyst heating. By closing both valves during an engine cold start, an elevated exhaust backpressure and increased heat rejection at an EGR cooler can be synergistically used to warm each of an engine and an exhaust catalyst. The valves may also be controlled to vary an amount of exhaust flowing through an exhaust venturi so as to meet engine vacuum needs while providing a desired amount of engine EGR.

Method and system for catalyst temperature control

Methods and systems are provided for diagnosing an engine thermal encapsulation positioned around a powertrain of a vehicle. In one example, degradation of the thermal encapsulation may be determined by comparing a temperature sampled via a sensor during engine off condition with an expected temperature.

Thermal engine encapsulation diagnostic

A method for a vehicle comprises responsive to installation of a new exhaust particulate filter, doping fuel with an ash-producing additive, and combusting the doped fuel to produce ash, wherein the ash deposits as an ash coating on the new exhaust particulate filter. In this way, a filtration efficiency of an exhaust particulate filter can be increased quickly as compared to a filter with no deposited ash coating, inexpensively as compared to conventional methods using membranes, and with a lower back pressure drop as compared to conventional methods.

System and methods for reducing particulate matter emissions

Methods and systems are provided for compensating an instantaneous fuel economy reading for stored energy. One method comprises, when a vehicle undergoes a sufficient change in one or more of square of vehicle speed and vehicle altitude, estimating a conversion factor for fuel due to stored vehicle energy and adjusting the instantaneous fuel economy reading by the estimated conversion factor. The adjusted instantaneous fuel economy reading may be displayed to an operator of the vehicle.

Method to adjust fuel economy readings for stored energy

A surface of a piston and/or a cylinder head and/or a cylinder bore of an internal combustion cylinder with selectively applied plasma transferred wire arc coating which acts as a thermal barrier improving fuel efficiency and reducing fuel emissions and a method of producing the plasma transferred wire arc coating on a surface of a piston and/or cylinder head and/or a cylinder bore of a compression ignition and/or spark ignition engine.

PTWA coating on pistons and/or cylinder heads and/or cylinder bores

Methods and systems for increasing fuel economy of a vehicle including a SCR catalyst are presented. In one example, an amount of EGR provided to an engine is decreased in response to performance of the SCR being within a predetermined range of performance. The methods and systems may increase vehicle fuel economy while vehicle tailpipe emissions are achieved.

System and method for increasing fuel economy of a vehicle including a SCR catalyst

Methods and systems are provided for improving engine spark and torque control. In one example, adaptive spark control of an engine may include a modifier that adjusts the inferred fuel octane estimate and a spark adaptation based on ambient humidity. The method allows the speed-load dependent variation in octane effect of humidity to be reduced.
