Abstract
In a device for preheating air in an air intake line leading to a Diesel engine in which a heating flange is arranged, the heating flange is switched off and on as required by means of a switching device comprising a semiconductor element as a switching element. At the same time, the state of a battery can be determined by measuring the voltage drop of the battery during such energization of the heating flange.
Claims8
A device for preheating air in a Diesel engine air intake line, comprising a heating flange arranged in said intake line and a switching device including semiconductor element for controlling energization of said heating flange by on and of switching of said switching device.
A method for testing the state of charge of a battery of a Diesel engine including an electric heating flange connected to an electric power supply by way of a semiconductor switch for preheating air in an air intake line leading to said Diesel engine, said method comprising the steps of switching on the electric power supply to said heating flange for energization of said heating flange for a specific period of time and measuring the voltage drop of the battery during such energization.
