Description of

Starting

System

Westerbeke diesel engines use electric starters assisted

glow plugs for both normal and cold weather

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

combustion chamber

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 to Westerbeke Diesels. The start circuitry is designed

that the PREHEAT

button

must be depressed for the time specified in the "Preheat" chart. Then, while keeping the

PREHEAT button engaged, the

START button

depressed to crank the engine.
