摘要： According to the invention, an apparatus for detecting slip of a drive belt (4) of a generator (1) driven by a drive motor (2) is proposed, in which the slip of a drive belt (4) can be determined by observation of the on-board electrical system voltage (Ub) and of the signal course at the terminal (DF) of the generator (1). For determining the slip, the largest possible electrical load (10) is switched, and the voltage course of the on-board electrical system voltage (Ub) before and after the switching of the electrical load (10) is evaluated. By additional observation of the signal at the terminal (DF) of the generator (1), it is precluded that electrical consumers that are not observed could adulterate the result.

摘要： A fuel conditioning and measuring system for testing diesel engines includes a fuel conditioning loop having first and second heat exchangers, one employing a heating medium, and one employing a cooling medium. Flow of the heating and cooling mediums to the heat exchangers is controlled by control valves which receive a signal indicative of the temperature of the fuel flowing through the system and compare the measured temperature to a desired temperature to generate a control signal for positioning the control valves appropriately. A mixing tank serves as a buffer between the fuel supply and the test engine to ensure any disturbances from fuel returning from the test engine do not adversely affect the testing of the engine, and provides a mechanism by which the temperature of the fuel can be more accurately controlled. A flow meter and a density meter measure the flow of fuel through the system to provide accurate indications of mass and volumetric flow.

摘要： An ignition coil, spark plug, and pressure sensor for an internal combustion engine are, in a preferred embodiment, integrated into a single assembly and mounted directly on a plug hole of an internal combustion engine. A hard spark plug shell serves as a pressure member and on which a strain gage is affixed. Changes in the pressure in the combustion chamber deform the shell, causing a corresponding change in the resistance of the strain gage. A bridge circuit or the like is used to measure the resistance change thereby providing a direct indication of cylinder pressure.

摘要： A process is suggested for checking the catalyst performance in internal-combustion engines, in which by means of detected operating parameters of the internal-combustion engine similar operating conditions are determined. It is suggested to compute from a defined number of measured exhaust gas values during a similar operating condition a statistically backed average exhaust gas value and compare it with a permissible exhaust gas value stored for this operating condition, so that a defective catalyst is recognized in the event of a deviation of the actually determined exhaust gas value from the permissible exhaust gas value.

摘要： A method of measuring a rate of change of carbon dioxide concentration in recirculated air of an engine, is disclosed. The method includes installing a conductive sample tube into an engine's pre-combustion/air-mixing chamber, and installing a carbon dioxide sensor, remote from the chamber, to measure relative concentrations of carbon dioxide. The method may also be used to measure nitrogen oxide exhaust gas levels.

摘要： A method of determining throttle flow in a fuel delivery system is disclosed. First, a time-efficient throttle flow data collection method is described. The collection method uses a sonic nozzle flow bench to measure airflow as a function of throttle angle and pressure in a manner analogous to on-engine dynamometer throttle flow characterization. Opening each sonic nozzle combination, then recording throttle downstream pressure and computed nozzle flow allows data to be taken in a fraction of the time normally needed. In conventional methods, the estimated airflow rate as a function of throttle angle differs from the measured airflow rate because the leak area is incorrect. The method of the invention correctly determines the estimated throttle airflow rate by using a low pass filtering technique to adjust the estimated airflow rate to eventually equal the measured airflow rate, particularly at small throttle angles.

摘要： A method for downloading and managing a test tool of a test system is proposed, which is applied to the test system having a test service server and a tested machine. A test tool required for performing a test for the tested machine is available as being downloaded from the test service server through a network, which connects the tested machine and the test service server, so as to examine if the tested machine works properly. As such, the test service server acts as a reservoir for the test tools and is used to activate start-up for the test, allowing the tested machine to be initiated with test conditions and user conditions for using the test tool being inputted to the test tool.

摘要： A method of determining a degree of oil degradation in the diesel engine depending on an injection end point in such an injection way as to cause the injection 0end point to be earlier that a specific point (TB) and depending on the injection amount after the specific point and the injection end point in such an injection way as to cause the injection end point to be later than the specific point. In every fuel injection, it is judged whether the injection end point is set before or after the specific point, and a current injection degradation value is obtained by using a corresponding map. A cumulative added value is obtained to judge the oil degradation.

摘要： An engine crankcase gas blow-by sensor. In a closed crankcase ventilation system, crankcase gases are caused to flow through a venturi which includes high pressure and low pressure taps. The high and low pressure taps are coupled to a differential pressure transducer which produces an output that is proportional to the volumetric flow of crankcase gases through the venturi. The use of a venturi in conjunction with a differential pressure sensor offers a low resistance path for the flow of crankcase gases and allows continuous monitoring of blow-by without exceeding the operating pressure limitations of various oil seals. Such a sensor is particularly suited for closed crankcase ventilation (ccv) systems, as it doesn't require venting of crankcase gases to the atmosphere, but works well in open crankcase ventilation systems also.
