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 (2) is measured as a primary control quantity by an air mass measuring apparatus (1) for the metering of fuel and the cylinder charge is computed via a control apparatus (3). A switchover to a substitute signal (P) as the primary control quantity takes place when a leak (8) is detected in the intake manifold (2) via a change of stored and actual pressure conditions.
