Title: Speed governor for diesel engine

A speed governor was developed for the 12ChSN 18/20 ship diesel engine to reduce emission of fumes and eliminate transient overloads, with pneumatic correction of the fuel injection rate according to the supercharge pressure. The device includes an electric corrector, and a hydraulic amplifier with slide valve. It is found that the regulator improves the performance, including torque and combustion characteristics and reduces the emission level to 15% within 2 s and decreases only to a 65% level. It was also tested on a Kometa hydrofoil ship with regulation of the diesel start over an 80 to 90 s acceleration period independently of the crank turning time, and maintained overloads and fume emission within prescribed limits.
