Abstract: A diagnostic system for an engine includes an error detection module and a diagnostic module. The error detection module selectively detects a fuel control error based on a change in a fuel correction value used to determine a quantity of fuel supplied directly to an exhaust system. The diagnostic module identifies a cause of the fuel control error based on a period since a last refueling event. The diagnostic module identifies the cause as one of variation in an actual heating value of the fuel and faulty operation of a fuel injection system that supplies the fuel. The diagnostic module further identifies the cause based on a first amount of the fuel contained in a fuel tank at a start of the last refueling event and a second amount of the fuel added to the fuel tank during the last refueling event. A control system and method are also provided.

Abstract: A system includes a pressure signal adjustment module that generates a maximum pressure signal based on a fluid pressure signal from a pressure sensor of a camshaft phaser system of an engine. The pressure signal adjustment module detects a maximum peak value of the fluid pressure signal and maintains the maximum pressure signal at the maximum peak value for a peak and hold period. A diagnostic module detects a fault of the camshaft phaser system based on the maximum pressure signal during the peak and hold period.

Abstract: An engine control system includes a cam phaser that introduces a cam phase angle θ between a camshaft intake lobe and an associated crankshaft. An engine control module communicates with the cam phaser to introduce the cam phase angle θ while an engine is being started. The cam phase angle θ is selected such that the camshaft intake lobe opens an intake valve during at least a portion of a compression stroke of a cylinder that is associated with the camshaft intake lobe.

Abstract: A vehicle includes a fuel tank, an internal combustion engine, an oxidation catalyst, a regenerable particulate filter in fluid communication with an outlet side of the oxidation catalyst, and a host machine. The host machine calculates an actual hydrocarbon level in the exhaust stream downstream of the particulate filter as a function of an actual energy input value and an actual output value of the oxidation catalyst, and subsequently executes a control action using the actual hydrocarbon level. A method for use aboard the vehicle includes using the host machine to calculate an actual hydrocarbon level in the exhaust stream downstream of the particulate filter, including solving a function of an actual energy input value and an actual energy output value of the oxidation catalyst, and executing a control action aboard the vehicle via the host machine using the actual hydrocarbon level.

Abstract: An engine control system comprises a fuel pump control module and a diagnostic module. The fuel pump control module controls a pressure pump to inject fuel into a fuel rail. The diagnostic module determines an estimated pressure increase within the fuel rail based on the injected fuel, compares an actual pressure increase within the fuel rail to the estimated pressure increase, and indicates when the actual pressure increase is less than the estimated pressure increase.
