Description

Starting System

Westerbeke diesel engines use electric starters assisted

glow plugs

for

both normal and cold weather

starting. The figure below shows a cross-sectional view of one cylinder. The glow plug is located in the com-

bustion chamber so that its tip is in the injector nozzle's spray path. When the

glow

plug is energized

the

PREHEAT button, the plug glows red at the

tip

and assists in igniting the fuel. The result is a rapid start with

less wear on the starter.

This system is common

Westerbeke Diesels. The start circuitry is designed so that the PREHEAT button

must be depressed

for

the time specified in the "Preheat" chart shown on page 33. Then, while keeping the

PREHEAT button engaged, the START button is depressed

crank the engine.
