Abstract
Revolution control in the marine diesel engine is accomplished with a governor, and an electro-hydraulic type has become conventional these days. Thus performance of the governor has improved so much, but it is complex, and some trouble can be expected. We are developing a new type of electro-hydraulic governor, one using a direct drive volume control hydraulic system. It has been installed aboard the training ship of TUMSAT "Shioji-Maru." By this paper we introduce our newly developed "Electro-Hydraulic engine Governor" which has the direct drive volume control hydraulic system. We continue to study the effects, for the reeducation of fuel consumption in Marine Diesel Engines.
