This instrument gives a technique for assessing the situation of inside combustion engine cylinders. It features by injecting pressurized air right into a cylinder at high lifeless middle on its compression stroke and measuring the speed at which that air escapes. The end result reveals the presence and severity of leaks previous valves, piston rings, or head gaskets. An instance software could be diagnosing low compression in an engine suspected of inside injury.
The process affords a extra direct evaluation of cylinder sealing integrity than an ordinary compression check. 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 drawback space. Its use dates again to the mid-Twentieth century with developments mirroring enhancements in engine expertise and diagnostic methods. The advantages embrace decreased diagnostic time, improved accuracy in pinpointing engine issues, and prevention of pointless repairs.
