Abstract (en)
[origin: WO9517979A1] Cleaning internal combustion engines (16) includes drawing cleaning fluid from a reservoir (22) by a pump (74), flushing through the block of the internal combustion engine (16), and returning the fluid to the reservoir (22) by the pump (74). Prior to cleaning, flushing and soaking the engine (16), lubricant is withdrawn under a pressure differential from the engine block. A vacuum can be applied to the oil drain (20) for the engine block for effecting this withdrawal. Additionally or alternatively, pressure can be applied to the oil filter opening (18) to the engine block for facilitating the withdrawal of the lubricant.
