摘要： A method for estimating exhaust temperature on an output of an internal combustion engine cylinder, the cylinder including a crankshaft transforming into a rotation a translational movement of a piston mounted sliding in the cylinder, the piston closing a combustion chamber of the cylinder. The exhaust temperature is estimated based on the temperature inside the cylinder at a time of opening of the valve, the temperature inside the cylinder being itself estimated from an angle of rotation of the crankshaft, cylinder pressure, volume of air injected into the cylinder, and flow rate of recycled gases. A method diagnoses a cylinder pressure sensor based on an estimate of the exhaust temperature.

摘要： In a vibration sensing device for sensing a knocking vibration of an engine, a piezoelectric element is connected to an output terminal through a resilient conductive member. The resilient conductive member has a fixed base part, a sliding part at a position opposite to the fixed base part, and an intermediate V-shaped part resiliently contacting the piezoelectric element. When the sliding part moves slidingly in response to vibration of the piezoelectric element, the sliding friction force which exerts on the sliding part increases the spring constant of the resilient conductive member to be larger than the stationary spring constant of the same by hysteresis characteristics, thereby reducing damage to the piezoelectric element and enhancing reliability of the electric connection.

摘要： An combustion state detecting apparatus for an internal-combustion engine is provided for preventing control errors and detection errors by preventing a biasing circuit from discharging at the start of energization, thereby allowing good sensitivity for detecting ionic current to be maintained. The combustion state detecting apparatus comprises an ionic current detecting circuit which includes a biasing circuit connected to the low voltage end of a secondary winding of an ignition coil and which detects ionic current flowing from the biasing circuit via a spark plug after the combustion of a fuel-air mixture. A current limiting circuit is provided between the low voltage end of the secondary winding and the biasing circuit. An electronic control unit detects the combustion state at the spark plug according to the ionic current. The biasing means circuit applies a bias voltage of the opposite polarity from high voltage for ignition to the spark plug via the low voltage end of the secondary winding; and the current limiting means controls the current flowing from the biasing means to the spark plug via the secondary winding, thus restraining the voltage at the high voltage end of the secondary winding when starting current supply to a primary winding.

摘要： The present invention relates to a detector for detecting leaks of a gas. The present invention is particularly applicable to a vehicle occupant restraint apparatus (10) which has a container (14) for an exothermically reactable gas mixture (18). An exothermic reaction of the gas mixture (18) released from container (14) deploys an occupant restraint (12). The detector has an electrically conductive sensor element (44). The sensor element (44) is positioned within an envelope (40) surrounding a portion of container (14) so as to be exposed to the gas mixture (18) if leaked from container (14). The sensor element (44) is part of an electric circuit (46). The electrical resistance of the sensor element (44) varies when the sensor element is exposed to the leaked gas mixture. The electric circuit (46) also has a power source (64) including a timing circuit (52) for providing an intermittent electric current through the sensor element (44). The timing circuit (52) has an off-period of relatively long duration. This allows the gas if leaked into the envelope (40) to accumulate in the area of the sensor element (44).

摘要： An instrument for measuring on-line the effective partial pressure of dissolved gases in a liquid includes a housing having a flow chamber for connecting in flow communication with a flowing stream of liquid to be measured, and a streamlined V-shaped wing rotatably mounted to the housing and extending across the flow chamber for presenting different angles of attack to the stream of liquid flowing through the housing chamber. The wing has an apex which remains located at a center of the stream of liquid flowing through the housing chamber as the angle-of-attack of the wing is changed relative to the stream of liquid. An actuating mechanism is coupled to the wing for rotating and thereby changing the angle of attack of the wing relative to the stream of liquid flow. A device, such as a viewing window or an acoustical detector, is coupled to the housing for use in identifying the occurrence of incipient cavitation bubbles at the apex of the wing.

摘要： A process for determining the combustion pressure of an internal combustion engine is proposed. Conventional processes of this type have the disadvantage that the determination methods are very costly. Furthermore, stringent requirements are made of the sensors to be used. By comparison, the process proposed here is distinguished in that the combustion pressure is calculated from the combustion chamber pressure (p(.alpha.)) determined with simple sensors, by determining the compression pressure (p.sub.k (.alpha.)). These values for the compression pressure are subtracted from the combustion chamber pressure in order to calculate the combustion pressure p*(.alpha.)). Preferably, the course of the compression pressure is obtained by measuring the combustion chamber pressure values during the compression until top dead center in the working phase and storing them in a memory. The compression values occurring after top dead center are obtained by reflection at an axis extending through top dead center, resulting in a symmetrical curve course for the compression pressure. In this way, the combustion pressure can be calculated particularly simply.

摘要： The pressure of a heated fluid is reduced in a test chamber. A small vent in the upper portion of the test chamber receives a stream of liquid from the chamber and yields a steady hiss when the fluid in the test chamber is under sufficient pressure to maintain the fluid solely in the liquid phase and it yields a sputtering hiss sound when the pressure in the test chamber is reduced sufficiently to permit steam and/or gases to coexist with the liquid in the chamber thus permitting liquid plus vapor to enter the vent. The change in sound may be used to alert an operator and/or pressure fluctuations in the test chamber may be automatically monitored to produce an output signal or a feedback signal for automatic control.
