The diesel oil must never be allowed to mix with the heavy fuel The temperature of the fuel from the pre –heater should be gradually reduced afterswitching over the three –way valve The heating steam to the pre-heater should be secured as soon as the diesel fuel passesthrough the three-way valve The heating steam must be secured before the diesel oil passes through the three-wayvalve
the power stroke the compression stroke low load operation only periods of standby
Lubrication systems using engine driven lube oil pumps do not require any additionalindependent arrangement when such arrangements have been proven reliable The use of engine driven pre-lube pumps is permitted on vessels with propulsion systemsdeveloping less than 500 shaft horsepower When forced lubrication is used for propulsion engines, one independently drivenstand-by pumps is to be provided in addition to the necessary pumps for normal operation Lubrication systems where two oil coolers are fitted require a minimum of twotemperature control devices which may be actuated by similar sensors
