Methods and system are provided to control engine torque of an engine of a vehicle. The methods comprise determining a drive torque demand on a crankshaft of an engine; determining an accessory torque demand on the crankshaft, the accessory torque demand comprising a first torque demand from a first e-machine and a second torque demand from a second e-machine; determining whether the sum of the drive torque demand and the accessory torque demand is greater than a usable torque capacity output from the engine crankshaft, and increasing a speed of the engine in response to determining that the sum of the drive torque demand and the accessory torque demand is greater than the usable torque capacity output from the engine crankshaft.

The invention relates to a method involving the treatment of the pollutants emitted by a vehicle having a heat engine, in which catalyst means (3) are heated, characterised in that the amount of oxygen (OS) in the catalyst means (3) is controlled to be over a minimum amount of oxygen (OS1) by injecting air upstream of said catalyst means (3).

An electrically heating converter includes: a pillar shaped honeycomb structure made of conductive ceramics, including: an outer peripheral wall; and a partition wall disposed on an inner side of the outer peripheral wall, the partition wall defining a plurality of cells, each of the cells penetrating from one end face to other end face to form a flow path; metal electrodes; conductive connecting portions arranged on a surface of the pillar shaped honeycomb structure; and a pressing member configured to press the metal electrodes against the conductive connecting portions, so that the metal electrodes are electrically connected to the pillar shaped honeycomb structure. Each of the conductive connecting portions has an electrical resistivity lower than that of the pillar shaped honeycomb structure.

Methods and systems are provided for a turbocharger. In one example, a method may include bypassing exhaust gases flowing to the turbocharger in response to a catalyst temperature being less than a threshold temperature. The bypassing includes opening a bypass valve and adjusting a position of one or more turbine nozzle vanes.

An engine assembly and a method of control thereof is provided. The engine assembly comprises: an exhaust gas aftertreatment device having an inlet for receiving exhaust gases leaving an engine; a heater for selectively heating gases at or upstream of the exhaust gas aftertreatment device; an air moving device for driving a flow of gases into the inlet of the exhaust gas aftertreatment device when the engine is in a non-running condition; and a controller configured to, prior to the engine being started: operate the heater to heat gases at or upstream of the inlet; and operate the air moving device to drive a flow of gases into the inlet to thereby heat the exhaust gas treatment device.

The invention relates to a heating device (3) for a storage container with a urea reducing agent, comprising at least one electrically operatable heating element (6) and a heat distribution element (7) which is thermally coupled to the heating element (6), wherein the heating element (6) has a first heating sub-element (40) which has at least one positive temperature coefficient thermistor (5), and the first heating sub-element (40) is connected to a second heating sub-element (42, 52, 62) which is designed to reduce the dependence of the heat output of the heating device (3) on an electric voltage applied to the heating element (6) in the event of an electric voltage with large values, in particular above 13 volt, so that the heat output dispensed to the thermal conducting element and the surrounding components with plastic encapsulation is not too high.

An electrical heater and method for heating a catalyst. The electrical heater includes a honeycomb body having a central axis extending longitudinally therethrough. The honeycomb body includes a matrix of intersecting walls forming a plurality of cells extending axially through the honeycomb body. A plurality of electrodes are positioned about an outer periphery of the honeycomb body. The plurality of electrodes are arranged into a plurality of pairs of electrodes that comprises at least a first pair of electrodes and a second pair of electrodes. Each pair of electrodes includes a first electrode and a second electrode. An electrode length of the electrodes along the outer periphery is proportional to a central current path length between center points of the electrodes of that pair of electrode. The electrode lengths of the electrodes of the first and second pairs of electrode are different.

A method for managing emissions from a vehicle having an aftertreatment system is provided. The method includes: receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and a power output of an engine of the vehicle; comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold; comparing, by the controller, the power output to a power output threshold; and responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage and disengage to warm the aftertreatment system of the vehicle.
