A device utilized to measure the pressure within the cylinder of a two-stroke engine during the compression stroke. This tool typically consists of a gauge, hose, and adapter that threads into the spark plug hole, allowing for an accurate reading of the maximum pressure achieved as the piston moves upward, compressing the air-fuel mixture. The resulting measurement serves as a key indicator of the engine’s overall health and performance capabilities.
Measuring cylinder pressure is crucial for diagnosing a range of engine problems, including worn piston rings, damaged cylinders, leaking valves, or head gasket failures. A low compression reading often signifies that the engine is not sealing properly, leading to reduced power, increased fuel consumption, and difficulty starting. Understanding the pressure generated within a two-stroke engine provides invaluable information for preventative maintenance and timely repairs, potentially extending the lifespan and efficiency of the motor.
