Method for controlling an internal combustion engine during uncontrolled combustion therein
Abstract:
Methods, systems, and computer program products are provided for controlling an internal combustion that comprises a cylinder having a space arranged to receive air and fuel, a piston disposed in the cylinder, and a crankcase being in fluid communication with the cylinder. The method comprises determining an uncontrolled behavior due to fluid flow between said crankcase and said cylinder space and combustion of such fluid, which entails: determining whether a powertrain of the vehicle is disengaged; determining whether the engine speed is increasing; and determining whether said cylinder space is receiving fuel. The method further comprises determining that an uncontrolled behavior is occurring if the conditions that: said powertrain is disengaged, the engine speed is increasing and said cylinder space is not receiving any fuel, are fulfilled.
