Description

Starting

System

Westerbeke diesel engines use electric starters assisted by

glow

plugs for both normal and cold weather

starting. The figure

below shows a cross-sectional view

one cylinder. The

glow

plug is located

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

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

the "Preheat" chart shown on page

39.

Then, while keeping the

PREHEAT button engaged, the START button is depressed

crank the engine.

NOTE: The START button will

not

energize unless the PREHEAT button is depressed. When

depressing

the

preheat switch, we are activating the glow plugs in the cylinder head, so use

the preheat intermittently so as

not

overheat the

glow

plugs.
