This instrument supplies a technique for assessing the situation of inner combustion engine cylinders. It features by injecting pressurized air right into a cylinder at prime useless middle on its compression stroke and measuring the speed at which that air escapes. The consequence reveals the presence and severity of leaks previous valves, piston rings, or head gaskets. An instance software can be diagnosing low compression in an engine suspected of inner harm.
The process presents a extra direct evaluation of cylinder sealing integrity than a typical compression take a look at. The audible location of escaping air helps pinpoint the supply of the leak. This identification avoids pointless disassembly and focuses restore efforts on the precise downside space. Its use dates again to the mid-Twentieth century with developments mirroring enhancements in engine know-how and diagnostic strategies. The advantages embody diminished diagnostic time, improved accuracy in pinpointing engine issues, and prevention of pointless repairs.
