A tool used to estimate cylinder pressure during engine cranking, this digital resource employs factors like engine displacement, cranking speed, and atmospheric conditions to provide insights into an engine’s internal health. For example, it can help distinguish between normal pressure loss due to factors like ring wear and more significant issues like a blown head gasket or burnt valves.
This diagnostic aid offers a quick, non-invasive method for assessing engine condition. By providing an estimated pressure value, it can help pinpoint potential problems, inform maintenance decisions, and potentially prevent catastrophic engine failure. Historically, evaluating engine compression required specialized, often cumbersome equipment. The advent of accessible digital tools has simplified this process, enabling quicker and more informed diagnostics.
