摘要:
A method pertaining to an SCR system for exhaust cleaning, includes deciding about a need, after cessation of an exhaust flow, to cool a reducing agent dosing unit (250) by a reducing agent supplied to it, and includes predicting a temperature pattern of the dosing unit (250) as a basis for deciding about the need and predicting whether a predetermined temperature of the dosing unit will be reached after cessation of exhaust flow. Also a computer program product containing program code (P) for implementing the method, an SCR system and a motor vehicle which is equipped with the SCR system are disclosed.

A method pertaining to an HC dosing system for exhaust cleaning for an engine which comprise a dosing unit (250) for fuel. After cessation of an exhaust flow, deciding about a need to cool the fuel dosing unit by use of fuel. Predicting a temperature pattern of the dosing unit (250) as a basis for deciding. Predicting whether a predetermined temperature of the dosing unit (250) will be reached after exhaust flow cessation. Also a computer programme product containing programme code (P) for implementing the method. Also an HC dosing system and a motor vehicle which is equipped with the HC dosing system are disclosed.
摘要:
The present invention refers to a pallet and a method for manufacturing said pallet. The pallet is made of sheet metal, preferably a one-piece sheet metal blank, said pallet comprising a load-carrying plane (2;2';2") provided with reinforcing grooves (7a,7b,8;7'a,7'b,8';7"a) and lateral pieces (3,4) provided with recesses (5) or openings (6), so arranged that the pallet is accessible from all sides for lifting means inserted beneath the load carrying plane (2;2';2").Significant for the pallet according to the invention is that almost all material in the blank is used. This is expecially brought out when the material sections moved aside, by folding, from the main planes of the lateral pieces (3,4), to create recesses (5) or openings (6), are comprised in box beams (40,41,48;40',41',48') reinforcing the pallet.

A roofing sheet intended to constitute external roofing, especially for roof constructions for small houses, comprises an upper edge which the mounted state of the sheet extends horizontally and perpendicular to the pitch, and is shaped to act as a beam, a lower edge which extends in parallel with the upper edge and is formed to overlap the upper beam section of an underlying sheet. The upper beam section and the lower edge are connected by groove-shaped portions, which in the mounted state of the sheet extend in the direction of the pitch.
