(a)	Investigate common agricultural engine configurations (e.g., inline and Vtype).
(b)	Define and determine agricultural engine measurements (e.g., displacement, compression ratio and clearance).
(c)	Differentiate between common valve train configurations (e.g., in block and single or dual overhead camshaft) in agricultural engines.
(d)	Describe the components and function of major, multi-cylinder engine subassemblies (e.g., cooling, exhaust, fuel and lubrication systems).

(f)	Compare the air flow of naturally aspirated and forced air turbocharged diesel engines.
(g)	Compare how fuel is supplied and ignited in spark ignition gasoline engines and compression ignition diesel engines.
(h)	Describe the advantages and disadvantages of different fuel sources used in agricultural engines.
