摘要： A system and method for measuring individual cylinder power contribution by cutting out individual cylinders of a multi-cylinder engine and performing a snap-throttle test on the engine. Engine speed versus time data is collected and stored during each snap-throttle test. This data is then used to calculate the power contribution provided by each cylinder using various methods, such as a least squares analysis of the speed data or by an analysis of the kinetic energy of the test engine.

摘要： A system and method for diagnosing output power of an internal combustion engine includes means for diagnosing potential causes of low engine output power or torque and means for estimating actual engine output power or torque. In a preferred embodiment of the diagnosis of engine output power, low engine output power is first investigated for authenticity to verify whether a low engine output power condition exists. If one exists, a zero fueling engine cranking test is conducted to determine whether relative compression values for each of the cylinders are within specification, and any problems associated therewith are corrected by service personnel. If the low engine output power problem is not corrected in accordance with the engine cranking test, a snap-throttle cylinder balancing test is conducted to balance the relative power contribution from each cylinder. If the cylinder balancing test does not correct the low engine output power problem, a road test is conducted to estimate the actual engine output power for comparison with a rated engine output power over a desired range of engine speeds.

摘要： A vehicle that has a drive train with an internal combustion engine, a transmission, and a number of ground engaging wheels. An operator-adjustable throttle control is monitored to provide a position signal corresponding to position of the throttle control. A sensor provides an observed speed signal corresponding to speed of the vehicle and a controller responds to the position signal and the observed speed signal to generate a target speed signal and an error signal. The target speed signal corresponds to a desired speed of the vehicle and is generated from a predetermined relationship between vehicle speed and throttle control position in accordance with the position signal. The error signal corresponds to a difference between the target speed signal and observed speed signal. The engine responds to the error signal to provide the desired vehicle speed for all operating speeds of the vehicle including a stopped or idle condition.

摘要： A test apparatus and method is disclosed for a fuel pump mounted on and driven by an engine, the speed of which is controlled by the pressure of fuel supplied thereto wherein the engine continues to be supplied with fuel from the fuel pump during the test. A fluid circuit is provided which is designed to supply fuel to the engine under controlled pressure to permit the engine speed to be controlled independently of the engine throttle position and to permit the flow rate of the fuel to be adjusted to a predetermined value at which the output pressure of the fuel pump may be measured for calibration purposes. The fluid circuitry and necessary measurement circuitry may be mounted within a small, portable housing to allow for field testing of a fuel pump.

摘要： A dual throttle system for an internal combustion engine includes first foot pedal throttle and a second hand controller throttle. The system includes a throttle position signal generator that produces a throttle position signal at an input to an electronic engine control module (ECM). The engine control module uses the throttle position signal input to determine an engine speed and issues appropriate commands to a fuel system controller. The throttle position generator includes a first potentiometer having its wiper mechanically connected to the first throttle and its output electrically connected to the throttle position signal input of the ECM. The first potentiometer is connected in series between a voltage source in the ECM and the wiper of a second variable resistance component driven by the second throttle. The output of the second component is connected to ground to complete the series circuit. The voltage seen at the throttle signal input of the ECM is a function of the combined series resistances of the potentiometer and the second variable resistance component based upon the positions of the respective throttles.

摘要： This disclosure relates to detection of air in the fuel supply system of an internal combustion engine of the character wherein the fuel rate supplied to the engine is controlled by regulating the feed pressure to a set of fuel injectors. A pressure sensor is connected in the fuel supply system and an engine speed sensor is connected to the engine. The engine is started, brought to a stable intermediate no-load speed, the throttle is snapped to a wide open position, and the rate of change of fuel pressure with time is sensed during the initial pressure rise from no load pressure to full load pressure. This measured rate is compared with a reference rate obtained from an engine where no air is present in the fuel system, and the pressure of air is indicated by a comparison of the measured and reference rates.

摘要： This disclosure relates to a system for analyzing the performance of a reciprocating piston, internal combustion engine such as a diesel engine. Sensors are connected to the engine, which respond to various operating parameters, and signals representing the parameters are fed to computer processing equipment. Two of the parameters are the lubricant system pressure and the engine speed. To test the lubricant system, the engine speed is stabilized at maximum governed speed and then the fuel supply to the engine is quickly cut off. The lubricant system pressure and the engine speed data are sensed and processed as the engine decelerates, the processing including a comparison of the pressure-speed characteristic with a standard or reference characteristic.

摘要： This disclosure relates to a system for measuring the instantaneous speed of an index point on a rotating part. The part may be a toothed gear or a wheel of an engine, and the index point may be an identifiable point on the part. The system comprises a sensor that is mounted adjacent the part, the sensor including two sensing elements that are spaced apart in the direction of movement of the point as the part rotates. As the point passes the sensor, it causes a first pulse to be produced by one element and then a second pulse to be produced by the other element. The system further includes circuitry that responds to the two time-spaced pulses and produces an indication of the time interval between the two pulses. This time interval is a function of the speed of the point which in turn is proportional to the rate of rotation of the part. In the instance where the part is attached to an engine flywheel, the time interval is also an inverse function of engine RPM.
