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.
This course provides a general introduction to the industry work environment including customer relations, work orders, build-sheets, and parts acquisition. Introduction to, and familiarization with the use of precision measurement and specialized, as well as, basic hand tools required will also be covered. Special emphasis is placed on both personal and shop safety due to the nature of potentially hazardous equipment.
The procedures of careful inspection and precise measurement technologies is taught. Combining this information, with the proper applications, formulas, and machinist math will be covered to provide a solid basis for successful production and high performance engine assembly procedures.
This course starts with exploring the basic theory and concepts of internal combustion engine operation. The course then moves into more specific and complex areas including torque, air flow, volumetric efficiency, operating cycles, and horsepower.
The individual components … their function, design, and material composition, and the differences will be covered. This will allow a clearer understanding of the relationship of the individual pieces to each other and the assembly as a whole. Production and performance variations will also be discussed.
The student learns the techniques of thorough examination and evaluation during disassembly to correctly diagnose engine failure, potential problems, and component replacement. Cleaning methods for both cast iron and aluminum are covered, including the impact of current environmental concerns. Additionally, crack detection methods and casting repairs are also covered.
The student learns the set-up and operation procedures of the machining equipment. He will also learn the procedures used to complete the machining of block and component parts. The differences between standard and high performance applications will be highlighted
Actual hands-on block and component machining will be accomplished by each student as they become proficient with all machining operations. Machined components will be carefully checked for accuracy. These pieces will become part of each student’s course project.
Blueprinting; the art of producing maximum capable horsepower, torque, volumetric efficiency, and R.P.M. through precise component assembly relationships will be taught. The effects of camshaft selection, degreeing, and valve timing in relation to cylinder pressure will be studied. Students will learn the real mystery of high performance
The primary focus of this course is mastering the art of assembling precisely machined components into a complete, operating engine block. Upon completion, the student will run his engine project on a Superflow Dynamometer for evaluation. Changes and adjustments will be made to demonstrate their effects on power output
The student is prepared to enter the job market by teaching the importance of personal appearance, conduct, and attitude. Job search, application, and interview are also covered. A brief discussion on career goal orientation and job placement assistance available from the School of Automotive Machinists completes the course
