摘要： A locomotive diesel engine test assembly generates a once-per-cycle signal phased to the top dead center of a predetermined piston in its cylinder. A locomotive diesel engine crankcase door is hermetically attached to the crankcase so as to cover a camshaft located therein. An outer tube extends through and is hermetically and fixedly attached to the crankcase door, and an inner tube extends through and is hermetically and pivotably attached to the outer tube. A proximity sensor is attached to the inner tube and positioned near and generally perpendicular to the camshaft. A marker is attached to the circumference of the camshaft and is detectable by the proximity sensor once per revolution of the camshaft.

摘要： A cylinder pressure sensor output compensation method for an internal combustion engine comprises the steps of determining the occurrence of a non-combustion state of engine operation, detecting the motoring cylinder pressure at this time, calculating a correction value (deviation) by comparing the detected motoring cylinder pressure with a reference value, and using this correction value to correct the sensor output during combustion of the engine. The method can be effectively applied to compensate for errors in sensor output due to variances in sensor characteristics from the time of manufacture or due to degradation through use.

摘要： A method and apparatus for determining the absolute compression pressure of each cylinder in an internal combustion engine is disclosed. The technique involves analyzing the changes in engine kinetic energy in order to calculate both the work of compression and expansion of each cylinder in a multi-cylinder engine typically during a decelerating engine cycle. Speed data is obtained and the work associated with the compression and expansion process for each cylinder is calculated and compared to the compression and expansion data of a good engine which is stored in computer memory. If a compression fault is present, it can be detected because that cylinder will display a decrease in both the work of compression and expansion. Once a faulted cylinder has been identified, the magnitude of the fault can be calculated and normalized and the compression pressure of each cylinder calculated and displayed.

摘要： To permit simple computation of control parameters, for example by an engine microcomputer, operating parameters of the engine are signalled by sensing instantaneous operating conditions such as speed, induction air pressure, or the like, preferably at a sensing angle of the crankshaft in advance of top dead center (TDC) position of a reference piston, and the average value is then determined by weighting the sensed instantaneous value to relate it to an average value in a weighting circuit (16). Preferably, the sensed signal is additionally modified in a function generator (15) as a function of then pertaining average conditions of at least one of: speed n; loading L.

摘要： A device for determining the timely delivery of compressed gas from compressed-gas containers for ejection and discharge tubes of submarines in which the compressed gas is suppliable via a system-controlled blowout valve comprising a compressed-gas container having a pressure pick-off with a pressure gauge and a converter for producing an electrical signal representing the actual pressure value. Upper and lower desired pressure values in the form of electrical signals are adjustable on transmitters electrically connected to separate comparator stages to which the electrical signal of the actual pressure value and, in each case, one of the signals of the adjusted predetermined values are supplied and by which a timing member having a running time indicator is controlled. The timing member is started when the pressure in the compressed-gas container falls below the adjusted upper pressure value and is stopped when the pressure in the compressed-gas container reaches the adjusted lower pressure value.

摘要： An injection timing transducer is provided for use with the fuel delivery system of a compression ignition engine. The transducer is operatively associated with the fuel flow path and provides a signal indicative of fuel pressure pulsations within the fuel delivery system. The electrical signals are representative of the derivative or rate of change of fuel pressure as a function of time and are thereby particularly suited for indicating the onset of fuel injection to the engine. The transducer includes a housing member connectable in the fuel flow path intermediate a fuel pump and injector for defining a chamber through which the fuel may pass and for providing a sensor mounting surface external to the chamber but in pressure transmitting relationship with the fluid path. A piezoelectric sensing element is affixed to the sensor mount surface of the transducer housing member. The housing member is typically an elongated, generally tubular member having a central fuel flow path at either end and wherein the chamber is an annular region within the member and radially offset from the central flow path. A continuous flow of fuel through the chamber is provided by radial flow paths between the central flow path and the upstream and downstream ends of that chamber. The annular chamber is conveniently provided by an insert member inserted in radially spaced relation within a central bore in one end of the housing member.
