Abstract: A supply passage extends through an inner sleeve in a radial direction and conducts hydraulic oil received from a hydraulic oil supply source. An axial passage is located between an outer sleeve and the inner sleeve and extends in an axial direction. The supply passage opens to one end portion of the axial passage while another end portion of the axial passage is configured to connect with a valve timing adjustment device. A supply check valve is installed in the axial passage and is located on a radial side of the supply passage where a radially outer side of the inner sleeve is placed. The supply check valve enables a flow of the hydraulic oil from the supply passage toward the axial passage and limits a flow of the hydraulic oil from the axial passage toward the supply passage.

In one example, a method may include actively manipulating a pressure in the fuel system during a refueling event, and indicating whether the variable orifice valve is degraded based on a loading rage of a fuel vapor storage canister with fuel vapors while the pressure is actively manipulated. In this way, it may be determined as to whether the variable orifice valve is stuck in a high-flow or a low-flow position such that mitigating action may be taken to reduce or avoid release of undesired evaporative emissions to atmosphere.

Abstract: AMP (2-Amino-2-Methyl-1, 3-Propanediol) does not release the absorbed heat during temperature drop but releases it during temperature rise. Also, AMP keeps a solid state upon the heat release. The heat storage material which is the aggregate of AMP is arranged to exchange heat with the subject for warm-up. In the warm-up acceleration control, it is judged whether or not there is a request for warm-up to the subject for warm-up (step S10). If it is judged that there is the request for warm-up, it is judged whether or not the radiation condition of the heat storage material is satisfied (step S12). If it is judged that the radiation condition is satisfied, the heater is started to operate (step S14). By operating the heater, the heat storage material is directly or indirectly heated.

Abstract: Methods and systems for starting an aircraft propulsion engine are described herein. Operation of the engine is controlled by an engine controller having a first channel and a second channel. An engine start request is received on the second channel while the first channel is inactive.

Responsive to determining that the last successful engine start was conducted on the second channel, a predetermined time period is waited to elapse and for the first channel to reinitialize before commanding, via the first channel, an engine start based on the engine start request.
