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