ENGINE SYSTEM

704W201A

The TD1300 and 3A150 engines are vertical, water-cooled, 4-cycle, three or four cylinders diesel engines. They concentrate DAEDONG’s foremost technologies.

With swirl combustion chamber, bosch K type fuel injection pump, well-balanced designs, they feature greater power, low fuel consumption, less vibration and noise, and low emission.

2. LUBRICA TING SYSTEM

(1) Piston (5) Strainer (9) Rocker Arm Shaft (13) Oil Pressure Switch (2) Idle Gear (6) Oil Filter Element (10) Rocker Arm (14) Camshaft (3) Oil Pump (7) Bypass Valve (11) Push Rod (15) Crankshaft (4) Relief Valve (8) Oil Pan (12) Tappet

The lubricating oil is forced to each journal through the oil passages of the cylinder block, cylinder head and shafts. The oil, splashed by the crankshaft or thrown off from the bearings, lubricates other engine parts such as the push rods (11), tappets (12), camshaft (14), and crankshaft (15).

3. COOLING SYSTEM

ENGINE SYSTEM

(1) Water Return Pipe (2) Thermostat (3) Cylinder Head Water Jacket (4) Cylinder Block Water Jacket

The cooling system consists of a radiator (5), a centrifugal water pump (7), a cooling fan (6) and a thermostat (2). The water is cooled as it flows through the radiator core, and the fan behind the radiator pulls the cooling air through the radiator core. The water pump receives water from the radiator or from the cylinder head and forces it into cylinder block. The thermostat open or closes according to the water temperature.

D704-W00 Dec. 2004

704W221A

(5) Radiator (6) Cooling Fan (7) Water Pump

When the water temperature is high, the thermostat opens to allow the water to flow from the cylinder block to the radiator. When the water temperature is low, the thermostat closes and the flow stays within the block. The opening temperature of the thermostat is approx. 71 °C (160 °F).

2-5

CHAPTER 2 CK25(H)/30(H)

4. FUEL SYSTEM

The fuel is fed from the fuel tank (1) through the fuel feed pump (7), through the fuel filter, and then to the injection pump (3). The injection pump force-feeds the fuel to the injection nozzles (5), which inject the fuel into the cylinders for combustion. The excess fuel from the injection pump and the injection nozzles (5), is collected in the fuel overflow pipes (6) and returns to the fuel tank.
