摘要:
A housing defines a bypass passage and a sub-bypass passage. The bypass passage draws a part of air flowing through an interior of a duct. The sub-bypass passage is branched from the bypass passage to draw a part of air flowing through the bypass passage. A flow sensor is equipped in the sub-bypass passage to cause heat transfer with air, which passes through the sub-bypass passage, and to generate an electric signal according to a flow quantity of air in the duct. An intake-air temperature sensor is configured to measure a temperature in the duct. A moisture sensor is configured to measure a humidity in the duct. The flow sensor and the multiple sensors are equipped in the sub-bypass passage and are located along a direction of flow of air in the sub-bypass passage.

Methods for controlling an aircraft turbofan engine during icing of a temperature probe and devices for carrying out such methods are described. The methods may comprise: using one or more signals representative of temperature received from a heated temperature probe to generate one or more control signals for use in controlling the engine; determining that an icing condition associated with the probe exists; and using data representing one or more substitute signals in place of signals representative of temperature received from the heated temperature probe to generate the one or more control signals for use in controlling the engine.

A sensor assembly for use in a vehicle. The sensor assembly has a housing for receiving a substrate. Terminals with substrate mating portions are provided in the housing. The substrate has components mounted thereon and plated openings which extend therethrough. The plated openings are provided in electrical engagement with the terminals. The openings are provided to mechanically and electrically engage the resilient contact portions of the terminals. The substrate mating portions are releasably pressure fit within the plated openings to allow the substrate to be removed and replaced as needed. The substrate mating portions maintain the electrical and mechanical connection between the substrate mating portions and the plated openings when the sensor assembly is exposed to vibration.

摘要:
A sensor system includes a sensor unit which has a pressure sensor, a temperature sensor and a selector switching between a pressure detection signal and a temperature detection signal. The sensor system further includes a processing unit which outputs a switching command signal to the selector and receives a detection signal from the sensor unit. The switching command signal is transmitted through a communication line and the detection signal is transmitted through a signal line. The detection signal is transmitted to the processing unit in a form of an analog signal.

In an internal combustion engine, at least one of the pressure and temperature in an intake passage downstream of a throttle valve is calculated using an expression of a relationship established based on the law of conservation of mass among an amount of air passing the throttle valve and flowing into the intake passage, an amount of exhaust gas passing an exhaust gas flow control valve and flowing into the intake passage, and an amount of gas flowing from the intake passage into a cylinder of the engine, and an expression of a relationship established based on the law of conservation of energy among an amount of energy of the air passing the throttle valve and flowing into the intake passage, an amount of energy of the exhaust gas passing the exhaust gas flow control valve and flowing into the intake passage, and an amount of energy of the gas flowing from the intake passage into the cylinder of the engine.
摘要:
A device for detecting the pressure and the temperature in the intake tube of an internal combustion engine, including a temperature sensor, a pressure sensor and a substrate each of which are secured in a housing with as little stress as possible with the pressure sensor secured on a substrate together with an evaluation circuit. The temperature sensor measures precise temperature measurement. In order to introduce a fluid medium that is under pressure, a neck part is secured to the housing and an adapter is joined both to the substrate and to the neck part via adhesive seals that decouple mechanical stress from the pressure and temperature detectors.
