(4) Max speed The angle of the control lever is set at determined engine speed. The governor keeps engine speed constant by adjusting sped when load changes. For example, if the operator moves the control lever with the link from the idling position to max. Output, governor spring tension increases, the tension lever is pulled until it comes in contact with the full load stopper, the movement of the governor lever is transmitted to the control rack via the link, maintaining the full load rack position, and engine sped increase until the governor weight thrust load and governor spring tension come into equilibrium at full load max. Speed.
(5) Necessity and function of angleich The governor must satisfy the required injection curves represented in the diagram below in order to obtain sufficient output at low speed, and not emit black smoke at high speed. the angleich spring was devised to provide for maximum torque at low sped by setting injection volume at point A, and shifting injection volume to point B' at high engine speed. 13
