Abstract
Systems and methods are provided for diagnosing cylinders in an engine. In one example, the method may include selecting a cylinder of the engine for perturbation, and while maintaining a horsepower output of the engine, perturbing the cylinder. Responsive to the perturbation of the cylinder inducing a crankcase pressure difference greater than or equal to a threshold difference, a degradation condition of the cylinder may be indicated. In one example, the perturbation may include cutting fuel to the cylinder. In one example, an engine load may be redistributed among each of remaining cylinder of a plurality of cylinders of the engine to maintain the horsepower output of the engine.
