Embodiment Construction

[0018] 1 shows a schematic diagram of a vehicle 1 and a control system for the vehicle according to an embodiment of the present invention, wherein 10 represents a six-cylinder internal combustion engine, such as a diesel engine, on which a crankshaft 20 is connected to a generally indicated by 30 Single plate dry plate clutch, which is located in the clutch box 40 . In addition to single-plate clutches, double-plate clutches can also be used. Crankshaft 20 is non-rotatably connected to clutch housing 50 of clutch 30 , while clutch plate 60 is non-rotatably connected to input shaft 70 , which is rotatably mounted to a gearbox indicated generally at 90 Inside the housing 80. A main shaft and an intermediate shaft are rotatably mounted in the housing 80 . An output shaft 85 extends from the gearbox 90 for driving the wheels of the vehicle.

[0019] The first pipeline 120 is used to deliver the exhaust gas from the combustion chamber of the engine to the exhaust manifold 140, ...

Abstract

Method and arrangement for achieving lower emissions during operation of a vehicle that includes comprising a combustion engine ( 10 ) that emits exhaust gases into an exhaust system ( 140 ) having a catalyzes ( 320 ). An injection device ( 310 ) is arranged to inject a substance into the exhaust system and a transmission ( 90 ) is provided that is driven by the engine. The method includes selecting a gear in the vehicle's transmission in response to at least information about whether catalytic conversion is required and information about the temperature (T) in the exhaust system so that the selected gear regulates the temperature in the exhaust system.

Description

technical field [0001] The invention relates to a method for achieving low emissions during driving of a vehicle, wherein the vehicle comprises: an internal combustion engine which emits exhaust gas to an exhaust system having a catalytic conversion device; injection means for injecting substances into the exhaust gas system; and the transmission, which is driven by the engine. [0002] The present invention also relates to a computer program for realizing the above-mentioned method by a computer. [0003] The invention also relates to an engine-propelled vehicle comprising: an internal combustion engine operating to emit exhaust gas to an exhaust system having a catalytic converter; control means; injection means for injecting a substance into the exhaust gas gas system; and a transmission, which is driven by the engine. Background technique [0004] In order to achieve low emissions, various types of catalytic conversion devices currently used for exhaust purification ha...
