JDAT1130 — John Deere Engines and Fuel Systems
This course deals with basic physical principles, operation and construction of two- and four-stroke cycle engines. It includes ignition timing of four-stroke cycle engines to factory specifications. Basic diagnostic engine test procedures will be practices on spark and compression ignition engines. This course also covers the types of internal combustion engine cooling systems, lubrication systems, air intake systems, exhaust systems, and fuel systems. Also covered is the basic theory, construction and operation of the engine valve train and the cylinder head, including valve timing and adjustments of actual John Deere engines. Also included are design, construction, operation and service methods for the following engine and fuel system components: crankshafts, connecting rods, piston assemblies, cylinder liners, bearings, fuel injection pumps, fuel injection nozzles and related engine accessories. Lab activities include disassembly, inspection, measurements, reassembly and adjustments performed on John Deere engines. Shop safety is stressed at all times. Location: M Classroom
