ENGINE COMPONENTS
THROTTLE CONTROL AIR CYLINDERS
the throttle control cylinder(s) controls the engine RPM. the cylinder is controlled by the operator’s throttle treadle valve. Various system components and the position of the engine idle switch can affect the RPM rang e available to the operator.
On Detroit Diesel engines, one cylinder provides the full rang e of engine RPM (750 to 2040 RPM) and also is designed to provide a mid range engine speed (1675 RPM) required while operating the dynamic retarding system.
On engines, two cylinders are required. the inboard cylinder provides full rang RPM (750 to 2300 RPM), the outboard cylinder controls the dynamic retarding RPM (1675 RPM).
