Abstract

Disclosed is a method for determining reliability regarding misfire determination of cylinders of an engine, comprising detecting a pressure in an exhaust manifold for a set of operation parameters comprising a certain range of crank angles for a certain engine load and certain engine speed so as to, for an actual cylinder setup of the engine, create pressure sample value patterns for combustion and misfire conditions. A template course is created for the thus created pressure sample value patterns comprising a set of sample points. The pressure for the created template courses is normalized at a desired crank angle. Difference values are determined based upon differences between sample points and corresponding detected and the normalized pressure values. The determined difference values are summarized so as to determine whether a predetermined share of the summarized difference values lies above or below a predetermined threshold value indicating reliability regarding misfire determination.

A diesel engine includes at least one cylinder (1) with a piston (2) having a piston bowl (3). A fuel injector (6) is configured to direct a fuel spray towards a target area (21) on an annular wall section (22) of the piston bowl so as to make a flame (20) formed by ignition of the fuel spray hit the target area. The target area borders, via a flow separation edge (23), on a lowered flow separation area (24) on the annular wall section so as to give this annular wall section a stepped configuration. The flow separation edge and flow separation area are configured to induce the formation of a vortex-filled wake between the flame and the flow separation area on the downstream side of the flow separation edge when the flame flows from the target area, across the flow separation edge and over the flow separation area.

A method and an apparatus for controlling driving power from a powertrain of a motor vehicle comprising a kickdown switch, wherein an activation of the kickdown switch triggers a default action of temporarily requesting an increase of a maximum power available from the powertrain, the method comprising: recognizing that a speed limiter, setting an upper speed limit for the vehicle speed, is active, comparing a current vehicle speed to a predefined speed threshold, which is below the upper speed limit, and if the current vehicle speed is above the speed threshold and the speed limiter is active, triggering an altered action in response to the activation of the kickdown switch.

Abstract

The present invention relates to a method for correcting a supply of additive to an exhaust gas stream resulting from combustion in an internal combustion engine. A first aftertreatment component being arranged for oxidation of nitric oxide into nitrogen dioxide, and a reduction catalytic converter being arranged downstream said first aftertreatment component. Additive is supplied to said exhaust gas stream for reduction of nitrogen oxides in said reduction catalytic converter, the additive being supplied in proportion to an occurrence of nitrogen oxides in said exhaust gas stream, said proportion being subject to correction. The method includes: supplying unburned fuel to said exhaust gas stream upstream said first aftertreatment component to reduce oxidation of nitric oxide into nitrogen dioxide in said first aftertreatment component, and correcting said supply of additive to said exhaust gas stream when supplying unburned fuel to said exhaust gas stream.

Abstract

The present disclosure relates to techniques in the context of vehicles, and in particular to methods for identifying parking areas for vehicles. According to one aspect, the disclosure relates to a method for identifying parking areas. The method comprises determining stops of a plurality of vehicles, wherein one stop is a geographical position where one vehicle of the plurality of vehicles has stayed longer than a pre-determined time period. The method further comprises clustering the determined stops into clusters based on spatial closeness of the geographical positions of the determined stops and determining parking areas by identifying one or more of the clusters that fulfil one or more pre-determined criteria. The disclosure is also related to a control arrangement and to a computer program for performing the proposed method.
