A method of determining a condition of a component (e.g., valves) of an engine having a manifold air pressure sensor during a cold test includes providing pressurized air to an intake of the engine. The method includes rotating a crankshaft of the engine. The method includes measuring pressures with the manifold air pressure sensor as a function of crankshaft rotational position. The method includes comparing the pressures with a predetermined baseline. The method includes indicating a condition of the component based on the comparison of the pressures with the baseline.

Device and method for cold testing engine component operation

A method of verifying a cylinder deactivation mode on an engine is provided. The method can include activating an ignition device in a deactivated cylinder during an exhaust stroke of the deactivated cylinder. The method can include measuring a voltage of the ignition device. The method can include comparing at least one of an amplitude and a timing of a measured spike of the voltage against a baseline voltage spike. The method can include indicating a status of the deactivation mode based on the comparison against the baseline voltage spike.

Device and method for detecting a cylinder deactivation mode using inferred compression

Current based methods and systems for testing an electromagnetically actuated fuel injector of an engine are provided. In at least one embodiment, an injector is commanded to actuate, data about a current associated with the command is collected, and a determination is made regarding whether the injector is functioning properly based on the data.

Methods and systems for testing electromagnetically actuated fuel injectors

A system and method for machining data management is provided. Vibration and operation data are gathered from a machine tool and sent to a processing unit. The processing unit defines operation-specific vibration profiles, and generates an operation-specific data line for each profile. The data lines are stored in a memory for later retrieval. An output device is used to retrieve the data lines and plot them over a time domain to create an operation-specific data matrix useful in manufacturing operations analysis.
