Assigned Department Objectives
Teaching Method
Outline:
The aim of this course is to help students obtain basic knowledge of diesel engine for handling.
This course deals with "output device" which is established as a part of the required subjects of training institution for ship officers.
Main themes are as follows.
・Classification of internal combustion engine
・Heat cycle of internal combustion engine
・Engine performance evaluation
・Ignition and combustion process
Style:
Lecture is conducted by one teacher.
Notice:
・Results are evaluated in respect to the achievement targets by a combination of examination (75%, midterm and final exams) and report (25%). More than 60% is needed to earn the credit.
・If the score is lower than 60, student can make up the examination by application. When it is admitted to acquire the credit by make-up examination, the score is 60.
・Required subject (training institution of ship officer) for licensed mariner of 3rd grade (engine)
1. Output device
(a) Working principle of diesel engine (b) Handling and maintenance of diesel engine (c) Failure detection and damage prevention of diesel engine
