An inlet system for an internal combustion engine is provided and includes a compressor including a rotor, and an air guide arranged to guide an air flow from an air inlet to at least one cylinder of the engine via the compressor. The inlet system also includes at least two fluid sources, and at least two fluid guiding elements each arranged to guide a fluid from a respective of the fluid sources to the air guide, between the air inlet and an outlet of the compressor, that the fluid guiding elements present a first conduit for guiding a fluid from a first of the fluid sources, and a second conduit for guiding a fluid from a second of the fluid sources, and that a restriction of a flow of the fluid from the first fluid source is provided by a downstream end of the first conduit and the rotor, whereby a downstream end of the second conduit is arranged so that a pressure drop provided by the restriction drives fluid through the second conduit towards the downstream end of the second conduit.

A fuel storage system is provided for storing dimethylether (DME), a blend including DME, or other similar highly volatile fuel at a vehicle. The fuel storage system including a main storage tank, an expansion tank, a fuel filling receptacle configured to receive a fuel filling nozzle of a filling station, and a valve arrangement having at least a normal operating setting and a fuel filling setting. The valve arrangement in the normal operating setting provides a fuel passage between the main storage tank and the expansion tank, and the valve arrangement in the fuel filling setting both provides a fuel passage between the fuel filling receptacle and the main storage tank and prevents fuel flow between the main storage tank and the expansion tank. The fuel storage system is configured to mechanically prevent disconnection of the fuel filling nozzle from the fuel filling receptacle unless the valve arrangement is in the normal operating setting. A corresponding method, as well as a further example embodiment of the fuel storage system, are also provided.

Arrangement (100) for an exhaust gas aftertreatment system (102) comprising a tank (104) for storing a reducing agent (106); a pump unit arrangement (108) arranged in downstream fluid communication with the tank (104); a nozzle (110) arranged to inject a flow of reducing agent, the nozzle (110) being arranged in downstream fluid communication with the tank (104) by a reducing agent conduit (112); an air conduit (114) arranged in fluid communication with the nozzle (110) for delivery of compressed air to the nozzle (110); and a return conduit (116) arranged in fluid communication between the reducing agent conduit (112) and the tank (104) and comprising a return conduit valve arrangement (118), wherein the air conduit (114) is arranged in fluid communication with the reducing agent conduit (112) for controllably delivery of reducing agent to the tank (104) via the return conduit valve arrangement (118) by means of providing compressed air from the air conduit to the reducing agent conduit (112).
摘要:
A hydraulic system includes a high pressure fluid source and a hydraulic actuator fluidly connected to the high pressure fluid source, and a low pressure fluid system fluidly connected to the hydraulic actuator via a fluid return line, and a hydraulic valve. The hydraulic valve includes a return spring and an elongate member, which is movably arranged in its longitudinal direction for controlling a fluid flow. The elongate member is biased to a closed position by the return spring. The elongate member forms a needle, the hydraulic valve includes a needle receiving body having a needle seat and the needle is engageable with the needle seat so as to control the fluid flow.
