Automotive Engine/Block Machining



Automotive Machinist Engine Block Machining Course Objectives

The program objective of Automotive Engine/Block Machining is to qualify the student as an automotive machinist. Although the actual machining process will be the emphasis of the program, a thorough education on theory of operation of the modem automotive engine will be presented. Performance modifications effect on power, longevity, and emissions, will be highlighted throughout the different courses.

This program is intended for the mechanically inclined student with a desire to work in the automotive industry.

One semester credit hour for each fifteen (15) hours of classroom contact plus appropriate outside preparation or the equivalent: or one semester credit hour for each thirty (30) hours of laboratory work plus appropriate outside preparation: or one semester credit hour for not fewer than forty-five (45) hours of shop instruction (contact hours) or the equivalent.

Single subjects making up this program are not offered individually. See the Equipment List Addendum for a complete list of machines used in the Automotive Engine/Block Machining program.
