Abstract

The invention provides an engine cleaning method and device and relates to the technical field of vehicle maintenance. The technical problem that cleaning oil flows circularly slowly in the engine when an engine is cleaned is solved. The engine cleaning device comprises a hydraulic pump, a two-position three-way reversing valve, an old oil bucket and a receiving disc. The hydraulic pump is locatedbetween an oil pan of a cleaned vehicle and the two-position three-way reversing valve. When the two-position three-way reversing valve keeps oil way connection of the hydraulic pump and an engine oil tank of the cleaned vehicle, an engine external cleaning loop is formed. The receiving disc and an engine lubricating oil way outlet are connected for receiving waste engine oil flowing out of the engine, and the bottom of the receiving disc communicates with the old oil bucket. The hydraulic pump works to facilitate acceleration circular flowing of the cleaning oil in a vehicle lubricating oilway. The engine cleaning method and device are used for cleaning and maintenance of the vehicle engine.

Description

technical field [0001] The invention relates to the technical field of vehicle maintenance, in particular to an engine cleaning method and device. Background technique [0002] Modern automobile engine design is very sophisticated, which reduces the degree of environmental pollution, improves fuel combustion efficiency, and prolongs the life of the engine, but at the same time, the requirements for the cleanliness of engine oil, oil additives and the engine itself are also greatly improved. [0003] When the engine is in good condition, it provides sufficient power with economical fuel consumption according to design requirements. However, after a period of operation, harmful substances such as carbon deposits and gums will be produced in the engine, which will slowly accumulate into sludge. It will increase the fuel consumption of the engine, reduce the power, fail to meet the precise matching clearance requirements of the engine, and even cause damage to the engine in sev...
