Abstract
A method for thermally coating the cylinder barrels of a cylinder block of a combustion engine is disclosed. Air flows through the cylinder bore whose barrel is to be coated. This air flow is generated by means of extraction, whereby the air is extracted from the bottom of the cylinder bore through the crank case of the cylinder block. For extracting the air, a plurality of extraction collars are provided that are connected to an extraction fan and are moved from the bottom through the crankcase to the lower end of the cylinder bores. The pressure of the air flowing through extraction conduits to the extraction fan is measured and the value of the velocity of the air flow through the cylinder bore is calculated. An adjustment mechanism controls air chokes in the air conduits in response to the calculated flow velocity present in the cylinder bores.
