WESTERBEKE'S 58 HP, FOUR CYLINDER, MARINE DIESEL

CONSTRUCTION 1. Cylinder Head: The special cast- iron cy linder head is precision­cast by the shell moulding process and then soft-gas·nitrided for increased durability. The intake and ex haust ports are arranged for cross fl ow to raise the intake and ex haust e fficiency. The swi rl type precombustion chamber is used.

2. Cyli nder Block: Weight reduction achieved by technologies of thin wall ductile cast iron and half skirt. The water rail is designed to provide uniform distribution of coolant to the cylinder head. The cy linder liner is of the dry type of high-phosphorus cast iron. which is given special honing to provide quick seating. and good oil retention. thus increasing wear resistance.

:~. Crank Mechanism: The forged crankshaft is supported by 5 beari n ~s. The au tolhermatic piston of Lo-Ex alloy has a sheet metal cast in i ts skir t so as to hold the thermal expansion of the piston . thereby mak ing il possib le 10 lessen the piston clearance. The pis­Ion pin is offset by O.5mm. All these improvements ensure quiet operation from low to high speeds.

4. Valve Mechanism: O.H.V. Both intake and exhaust valves are of rotation type for higher durability of the valve seat. Coupled with a friction gear with one extra tooth. the timing gear train is intended to el iminate the backlash at the time of gear engagement to reduce gear noise.

5. Intake System: The intake manifold is of independent branch type for higher intake efficiency.

6. Fuel System: The fuel injection pump is a Bosch VE type dist rib­utor pump. small in size and light in weight. cont ributing toward noise reduction . Since fuel can be cut with the solenoid valve built in the pump. the engine operation can be stopped by turning off the ignition switch.
