A tool designed to measure the strain throughout the cylinder of a two-stroke engine in the course of the compression stroke. This specialised instrument usually incorporates a threaded adapter to suit the spark plug port, a strain gauge to show the studying, and a launch valve for subsequent exams. The measured strain, expressed in kilos per sq. inch (PSI) or bar, supplies a sign of the engine’s inner situation.
The utilization of such instrumentation provides a crucial evaluation of engine well being, revealing potential points comparable to piston ring put on, cylinder harm, or leaky seals. Common evaluation aids in preventative upkeep, minimizing downtime, and optimizing engine efficiency. Traditionally, these exams supplied important diagnostic data for mechanics engaged on more and more advanced combustion engines, permitting for focused repairs as a substitute of full overhauls.
