Abstract: A method for detecting a low-lift or zero-lift failure mode in a variable valve activation system of an internal combustion engine includes the steps of positioning a piezo-electric element that acts as a radio frequency transmitter relative to a lost motion spring of a two-mode variable valve activation lost motion device, subjecting the piezo-electric element to a compression load when a load from displacement of a lobe of a camshaft acts on the lost motion spring, broadcasting a radio frequency signal each time the piezo-electric element is subjected to the compression load, and evaluating the presence or absence of the broadcasted radio frequency signal in relation to an expected presence or absence of the radio frequency signal. The direct measurement of the mode of each two-mode device is both more reliable and more efficient in the use of engine controller resources compared to currently existing diagnostic methods.

Abstract: A method for controlling dual independent camshaft phasers in an internal combustion engine. The method has three basic steps: a) first, determining if rate balancing between the two phasers is required; b) second, determining the optimal rate balancing commands; and c) third, applying the determined rate balancing commands to the appropriate phaser(s). In determining the rate balancing commands, there are three possible phaser options: the intake phaser requires priority; the exhaust phaser requires priority; or neither phaser requires priority. Lookup tables are stored in the engine controller for each option. When either phaser has priority, the other phaser is actuated after a delay based upon the position error of the priority phaser, generally at a lower phase rate. When neither phaser has priority, both phasers are actuated at a rate consistent with oil-delivery capabilities of the engine.

Abstract: A method for providing supplemental internal air cooling to a multi-cylinder internal combustion engine. The method involves deactivating the fuel injector to one cylinder for a predetermined time period or temperature decrease, based upon engine operating conditions, and then reactivating the fuel injector. This results in cool air being pumped through the fuel-deactivated cylinder by the reciprocating action of the piston therein, which air-cools the walls, piston, and head of that cylinder from the inside. In response to a controlling algorithm in an Engine Control Module, various of the engine fuel injectors may be deactivated and then reactivated sequentially to provide distributed cooling over the entire engine. The invention is especially useful for motorcycle engines having two or more cylinders when the motorcycles are used at low or stop-and-go speeds, such as in parades or other ceremonial functions.

Abstract: In a multi-cylinder internal combustion engine having intake valve deactivation apparatus providing de-activation of the intake valves of selected cylinders during engine operation, correct cylinder activation status is verified by measuring gas pressure in a conduit conducting combustion related gases through the cylinders of the engine, detecting consecutive pulses in the pressure due to predetermined activations of the intake valves, comparing the time periods between the consecutive pulses to reference time periods based on crankshaft position and corresponding to expected time periods between the consecutive pulses and providing verification signals and cylinder identification of faulty intake valve deactivation or activation in response to the comparisons.

Abstract: A method for diagnosing the operational state of a variable valve lift device (VVL) is provided. The method includes providing a first signal indicative of an estimated position of the VVL, the first signal having a first signal-to-noise ratio; determining that the first signal represents either a first condition indicating that the VVL is operating in one of two modes of operation, a second condition indicating that the VVL is not operating in the two modes of operation, and a third condition where the first signal is not in the first or second conditions; and adjusting a camshaft phase angle when the first signal is in the third condition so that the first signal has a second signal-to-noise ratio, wherein the second signal-to-noise ratio is greater than the first signal-to-noise ratio, whereby the operational state of the VVL is identified as one of the first and second conditions.

Abstract: A common optical path interferometric gauge comprises an optical beam that is split into two beams. Both beams are modulated and recombined after introducing an optical path length difference greater than the coherence length of the optical source. The combined beam is guided along a common optical path and is subsequently split into reference and measurement beams. The measurement beam is guided along a measurement optical path that includes a moving workpiece surface. Both beams are recombined after interposing an optical path length difference therebetween so as to reestablish coherence between portions thereof, producing optical interference indicative of the surface movement.

Abstract: Apparatus and method for optically scanning the circumference of a generally circular section of a test object, and especially for monitoring the surface character of cables and the like. An optical system has its apparent axis substantially concentric with the centerline of the path along which the cable moves relative to the scanning optics. A beam of radiation is caused to rotate or orbit about that axis and is then directed into near-normal incidence with the surface of the test object such that it is specularly reflected by the surface. The optical system redirects the reflected beam toward one or more detectors, the intensity of outputs of which provide an indication of the surface character of the object.In a preferred embodiment, a radiation source beam offset from the actual cable path is rotated by a pair of oscillating mirrors such that it describes a divergent conical shape. Certain optics direct a 180.degree. portion of that rotating beam along one path to intersect with a corresponding 180.degree. segment of the cable and a dividing mirror and similar optics direct the other 180.degree. portion of the beam along another path to intersect with the remaining or complementary 180.degree. segment of the cable. By so dividing the beam paths, a full 360.degree. scan of the cable surface is obtained without the cable "shadowing" any part of the incoming beam. The reflected radiation is "returned" along two respective paths to a respective pair of detectors. Some of the optical elements may be movable relative to others to facilitate coupling and uncoupling the apparatus with the cable.
