Summary

This Book is a companion to Volume 8 in the same series and is a specific examination guide for the syllabuses of Motor Engineering Knowledge for the Second and First Class Marine Engineers' Motor Certificates and Endorsements. Subjects covered include basic cycles, indicator diagrams, starting and reversing systems, cylinders, pistons, crankshafts and deflections, medium speed diesel engines, governors, control, waste heat systems, and crankcase explosions. Also included are typical exam questions for practice.
