3.7. Fuel System The fuel is delivered by the fuel feed pump via the fuel filter to the injection pump and from there to the injection nozzles. The fuel is sprayed into the cylinders through nozzles fitted in screw-fit injection nozzle holders in the cylinder heads. Excessively delivered fuel and leak fuel from the nozzle flow through the return pipe back to the tank. A strainer is arranged ahead of the fuel feed pump. 3.7.1 . Fuel filter This fuel filter has two functions not only oil filtering but also water separating Before entering the suction chamber of the injection pump, the fuel is cleaned ina strainer of fuel feed pump and a fuel filter.
Drain the ; cock in cartridge under with loosening filter manually (6) from time to time. The fuel filter should be replaced at EA204009 every 400 hours. 3.7.2. Fuel requirements DAEWOO marine diesel engines was designed that meets specification ever possible. When DIN 51601-DK. to use For maximum Number 2-D diesel fuel or equivalent fuel economy, Number temperatures are below -7 °C (20 °F), use Number 2-D fuel when- 1-D fuel. If Number 1- D fuel is not available, the mixture of one kerosene to two gallons of Number 2-D fuel can be used. Once kerosene has been added, the engine should be run for several minutes to mix the fuel. 3.7.3.
How to select fuel oil Fuel quality is an important factor in obtaining life, and acceptable exhaust emission levels. satisfactory engine DAEWOO engines performance, are designed long engine to operate most diesel fuels marketed today. In general, fuels meeting the properties of ASTM D975 (grades The ASTM 975 specification, istics needed for assurance The on Designation 1-D and 2-D) have provided satisfactory performance. however, does not in itself adequately define the fuel characterof fuel quality. properties fisted in the fuel oil selection chart below have provided optimum engine per- formance. Grade 2-D fuel is normally available for generator service.
Grade 1-D fuel should not be used in pleasure craft engines, except in an emergency. wy} i water -17-
