An upper cylinder lubricator/cleaner device for fitment to the inlet manifold of an LPG (liquified petroleum gas), CNG (compressed natural gas), fuel driven automotive, internal combustion engine. The device has a plastic bottle (10) with an air-vented cap (11) and is refillable with lubricant/cleaner; an in-line vacuum chamber is formed by a transparent sight glass (23), mounted outside the bottle (10) and interposed between a siphon suction tube (13) submerged in the bottle and a vacuum line (27) supplying lubricant/cleaner into an engine combustion air/gas stream via a vacuum port of the inlet manifold. Intermittent flow of lubricant/cleaner in the form of droplets (28) is visually monitored by means of the sight glass (23) and lubricant flow is metered by manual adjustment to any preset position by clockwise or anti-clockwise rotation of an adjustable, externally screw threaded needle valve (20) mounted within an internally threaded T-piece (14) connecting the siphon suction tube (13) to the sight glass (23). |
