Abstract
The invention relates to a method and a control arrangement for the metering of fuel in an injection system, especially for engines having an exhaust-gas turbocharger. The inducted air mass in the intake manifold ( ) is measured as a primary control quantity by an air mass measuring apparatus ( ) for the metering of fuel and the cylinder charge is computed via a control apparatus ( ). A switchover to a substitute signal (P) as the primary control quantity takes place when a leak ( ) is detected in the intake manifold ( ) via a change of stored and actual pressure conditions.
