摘要： In some examples, a system includes an airflow sensor disposed at least partially within an air intake system for an engine. The airflow sensor may be configured to measure a flow rate of air flowing past the airflow sensor in the air intake system, and includes a sensor element and a heater associated with the sensor element. A heater control circuit may control the heater to control a temperature of the sensor element. Further, a processor may be configured by executable instructions to cause the heater control circuit to, in a first operation mode, maintain the sensor element at a higher temperature range, and, in a second operation mode, maintain the sensor element at a lower temperature range that is above an ambient temperature and that is lower than the higher temperature range.

摘要： In some examples, a mass airflow sensor apparatus includes a housing having a tubular bore for passage of air, with an airflow sensor disposed at least partially within the tubular bore. The airflow sensor may be configured to measure a flow rate of air flowing past the airflow sensor. A focus component may be disposed upstream of the mass airflow sensor, the focus component including a cylindrical tubular focus member suspended within the bore. Further, a nozzle may be disposed upstream of the focus component. The nozzle may include a conical inner surface angled toward a center of the bore. In addition, a grid component may be disposed upstream of the focus component. The grid component may include a mesh grid including a plurality of openings for smoothing a flow of air flowing toward the airflow sensor.

摘要： In some examples, a fuel injector rail assembly may include a fuel rail including a tubular body, with a fuel outlet passage formed through a wall of the tubular body. An injector cup may be connected to the tubular body and may include an injector chamber configured to receive a fuel injector. A first fuel passage formed in the injector cup may include a first diameter, and the first fuel passage may be connected to the fuel outlet passage of the tubular body. Additionally, a second fuel passage may be formed in the injector cup between the first fuel passage and the injector chamber. The second fuel passage may have a second diameter that is smaller than the first diameter of the first fuel passage.

摘要： A shock absorber having an outer tube, an inner tube disposed coaxially in the outer tube and a piston reciprocally mounted in the inner tube. The interior of the inner tubes forms a working chamber for hydraulic oil while an annular replenishment chamber is formed between the inner and outer tubes. An improved base plate and base cage assembly facilitates fluid flow from the replenishment chamber to the working chamber during an extension cycle of the shock absorber.

摘要： A fuel rail for a direct injection engine. The fuel rail includes an elongated tubular housing which defines an elongated main chamber. An elongated tube is disposed in the main chamber of the housing and defines an inlet chamber inside of the tube and an annular outlet chamber between the housing and the tube. The tube has a fuel inlet open to its inlet chamber and adapted for connection with a fuel pump. At least two orifices are formed through the tube which fluidly connects the inlet chamber with the outlet chamber. The orifices are positioned and sized to minimize fuel pressure gradients in the fuel rail caused by fuel injection by the fuel injectors.
