摘要： The diagnosis of the heating of a catalytic converter situated in an exhaust system of an internal combustion engine is described. The system includes monitoring the actual ignition angle intervention. A current ignition angle is acquired over a specified time and converted into a torque model used for catalytic converter heating. Using the torque model, a degree of fulfillment of executed catalytic converter heating measures is obtained and an error signal is generated by comparing the obtained degree of fulfillment to a limiting value.

摘要： Formaldehyde is removed by distillation from reaction solutions containing a methlolated alkanal which was obtained from the reaction of formaldehyde with an alkanal which has at least one acidic hydrogen atom &agr; to the carbonyl function or from the reaction of a 2-alkylacrolein or acrolein with water and formaldehyde, by a process in which this reaction was carried out in the presence of catalytic amounts of organic amine. The process permits the improved removal of formaldehyde from the reaction mixture and furthermore facilitates the hydrogenation of the alkanals thus obtained to give polyols.
