    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 controller may determine, from among a plurality of energy storage units, a first energy storage unit having a higher than median charge and a second energy storage unit having a lower than median charge. The controller may connect the first energy storage unit to a resonant circuit to transfer energy from the first energy storage unit to the resonant circuit. The controller may then disconnect the first energy storage unit from the resonant circuit, and connect the second energy storage unit to the resonant circuit to transfer energy from the resonant circuit to the second energy storage unit to at least partially balance a charge difference between the first energy storage unit and the second energy storage unit.

    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 injector with an anti-rotation clip for use in conjunction with a twist lock fuel injector inserted into a receiving fuel cup. The clip includes at least one connector leg which extends at least partially over the electrical connector for the fuel injector and locks the clip against rotation relative to the fuel injector electrical connector. A protrusion on a fuel cup arm engages a notch formed in the fuel cup to lock the arm against rotation relative to the fuel cup.

    摘要: Some examples include a damper having an outer tube with a piston reciprocally mounted on an interior of the outer tube. A dampening force generating mechanism may be mounted on the outer tube within a threshold distance from a first end of the outer tube to control a dampening property of the piston. In addition, a vehicle interface adapter may seal the first end of the outer tube. The vehicle interface adapter may include an insertion portion extending outward from the first end of the outer tube. The insertion portion is able to be inserted into a cup-shaped portion of a vehicle attachment receptacle. The insertion portion may have a cylindrical wall forming a cylinder that is aligned coaxially with the outer tube.

    摘要: In some examples, at least one connecting ring may connect a plurality of stator coils of the same phase. For instance, the at least one connecting ring may include at least one linear conductor formed in a ring-like shape. The linear conductor may include a plurality of terminal sections, each terminal section including an open groove extending perpendicular to a plane formed by the ring-like shape. The open grooves may be positioned around a circumference of the connecting ring for receiving respective wire ends of respective stator coils inserted into the open grooves for forming an electrical connection between the respective wire ends and the connecting ring at the respective terminal sections.

    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.
