摘要： A method is presented for determining whether a fuel sensor in a vehicle having a fuel tank, a fuel delivery system, electronic engine controller, air flow and air/fuel ratio sensors and an instrument panel is stuck in-range. First, the electronic engine controller from the information provided by the above sensors estimates an amount of fuel consumed. The estimate is then compared to the actual fuel consumed data from the fuel sensor. If the difference between the actual and estimated amounts exceeds a small predetermined constant, the determination is made that the fuel sensor is stuck in-range and a diagnostic code is sent to the instrument panel and stored for use by a service technician.

摘要： An arrangement for isolating an energy transfer system while it is subjected to a test process for noise. The energy transfer system is of the type having an energy input and at least one energy output, and may be mechanical or electrical. The isolation arrangement has a base that supports the energy transfer system. An isolation support supporting the energy transfer system, yet affords multiple degrees of freedom with respect to the base. The energy transfer system is clamped in a manner that permits at least one degree of freedom with respect to the base, via an engagement arrangement that secures the energy transfer system to the isolation support. When mechanical or electrical energy is applied to the energy transfer system, acoustic energy in the form of sound and/or vibration is issued by the energy transfer system under test, which acoustic energy is monitored by an acoustic sensor that issues a corresponding electrical signal. The monitored acoustic energy is responsive to a qualitative condition in the energy transfer system under test, and also to a temperature thereof. A thermal sensor monitors a temperature change in the energy transfer system under test, and the resulting temperature-responsive electrical signal is employed to control the sensitivity of the acoustic sensor. Such temperature-responsive control is effected non-linearly in certain embodiments of the invention.

摘要： The invention is directed to an on-board diagnostic method wherein a fault is detected but is only registered as a fault when a delay time span has elapsed since its first-time occurrence in an operating phase of an internal combustion engine and when the fault then still continues to occur. The delay time span is measured on the consumption of the quantity of fuel which the vehicle can still consume for an almost empty tank. In this way, detected faults, which are attributable to an empty tank, are not registered.

摘要： In a reciprocating engine, power strokes of pistons apply torque to a crankshaft causing it to twist proportionally. Datum time moments are established by triggers rotating with, at one end of, the crank shaft and a sensor sensing passing of the triggers. At an opposed end, ring gear teeth trigger a sensor. At no load, zero twist occurs and arrival time moments of the triggers in relation to the datum time moments are predictable. Under load, twisting in the crank shaft causes the arrival time moments to be delayed, the time lag being proportional to the twist, bearing in mind the effect of rotational speed. With information about physical twist-torque characteristics of the crankshaft, torque values are calculated from the measured twist values, and are used in engine management. The invention can be applied to any shaft, for example also a main shaft of a gas turbine engine.

摘要： In a fuel injection type multicylinder engine, both the mounting of a camshaft angle sensor, which is operable in response to angular movement of a valve driving camshaft to detect a timing of injection of fuel injected from a fuel injection valve, on the engine and maintenance of the resulting engine are improved. A camshaft angle sensor S is operable in response to an angular movement of an exhaust-side valve driving camshaft and is mounted on the engine E at one side surface exposed from the lower portion of a frame F. Mounting of a cam pulsar of the angle sensor S from the side of the frame F and the maintenance is possible without being obstructed by the frame F.

摘要： A load machine for a combustion engine test bench includes at least one eddy-current brake associated with at least one electric drive. The brake includes a toothed ferromagnetic rotor secured to a shaft mounted so that it can rotate through a casing containing at least one induction coil borne by an internal peripheral region of the casing, so as to generate a magnetic field across which the rotor is intended to pass in order to generate eddy currents which brake the rotation of the shaft. The shaft is coupled to the combustion engine to be tested, and the electric drive is a variable-reluctance electric motor.
