摘要:
An oil gas separating device comprising a series of chambers (4a to 4g) fluidly connecting a gas inlet port (2) and a gas outlet port (5). Each chamber is provided with an oil reservoir (9) in a lower portion thereof and consecutive chambers are arranged to alternately direct gas in an upward direction away from a respective reservoir and in a downward direction towards a respective reservoir. Oil is retained in the reservoir by cohesion of oil droplets with the reservoir.
摘要:
A throttle valve for use with an internal combustion engine. The valve comprises an inlet port arranged to receive an air/fuel mixture, an outlet port arranged to communicate an air/fuel mixture to an engine and a closure member arranged between the inlet port and outlet port. The closure member is arranged in use to cooperate with the inlet port so as to define a passage between the inlet and outlet port with an adjustable cross-sectional area. The profile(s) of the of the inlet port and/or closure member is/are adapted in accordance with at least one operating characteristic of an engine.
摘要:
A starter system for start up of a combined heat and power unit comprising a generator which is connectable to the grid. The starter system comprises a variable frequency drive, VFD, operable to receive power from the grid. The VFD reduces the frequency of the power, and provides the reduced-frequency power to the generator to start the generator. The starter system further comprises a bypass relay configured to bypass the VFD. The bypass relay allows direct connection between the grid and the generator after the generator has started. The variable frequency drive is configured to operate temporarily during start up of the combined heat and power unit.
