Embodiment Construction

[0056] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which example embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for sufficiency and completeness. Throughout the specification, the same reference numerals denote the same elements.

[0057] special reference figure 1 , a vehicle 10 in the form of a truck is provided. The vehicle 10 includes a prime mover 100 in the form of an internal combustion engine arrangement 100 . The internal combustion engine arrangement 100 may for example be propelled by a conventional fuel such as diesel, although other alternatives are conceivable. The internal combustion engine 100 is preferably operated in a four-stroke manner, ie with an intake stroke, a compression stroke, a combustion stroke and an exhau...

Abstract

The present invention relates to a method for controlling an internal combustion engine arrangement (100). The internal combustion engine arrangement (100) comprises a combustion cylinder (102) and aninlet valve (106) arranged to be positioned in a closed position at a distance before a piston (104) reaches a bottom dead center during normal operation. The inlet valve is further controllable to be arranged in the open position until the piston reaches the bottom dead center if a required volumetric efficiency of the combustion cylinder is higher than a volumetric efficiency during normal operation.

Description

technical field [0001] The invention relates to a method for controlling an internal combustion engine arrangement. The invention also relates to a corresponding internal combustion engine arrangement. The invention is applicable to vehicles, particularly light, medium and heavy duty vehicles commonly referred to as trucks. Although the invention will be described primarily in relation to trucks, the invention is also applicable to other types of vehicles. Background technique [0002] The demand for internal combustion engines has been increasing steadily over the years and the engines are constantly evolving to meet the various demands from the market. Reduction of exhaust gases, increased engine efficiency (ie reduced fuel consumption) and reduced noise levels from the engine are some of the criteria that become important aspects when selecting a vehicle engine. Furthermore, in the field of trucks there are applicable laws and regulations which, for example, have estab...
