The measured values are processed to calculate a respective unbalancing value representative of the fuel quantity injected by the fuel injector. An average value of the calculated unbalancing values is calculated and subtracted from each of the unbalancing values to obtain a respective adjusted un...
deactivating a subset of cylinders of a multi-cylinder engine, performing a power balance test to determine an output of each cylinder after a duration of deactivation, and indicating that a deactivated cylinder has a degraded fuel injector responsive to the output being lower than a threshold outp...
A method for determining a faulty fuel injector 24 in an engine is described. The method comprises maintaining engine at a predetermined speed, determining time taken for a piston of at least one engine cylinder 30 to move from a top dead center crank angle point A to a reference crank ...
A method of detecting a faulty injector in an engine includes initiating a cylinder deactivation mode for operating the engine. The method deactivates a first engine cylinder operating in the cylinder deactivation mode and calculates a first contribution value for the first engine cylinder based on ...
