Valvetrain Testing
Combustion and valvetrain movement are highly dynamic processes with extreme speeds and accelerations. Measuring valve motion presents special challenges, including separating valve motion from cylinder head displacement and measuring large displacements with high resolution.
A differential, high-speed vibrometer is an excellent measurement solution and can provide accurate valve motion graphs essential for optimizing the combustion process, fuel consumption, engine performance and service life. A measurement range of up to 30 m/s allows measurements even on Formula 1 engine systems.
