Description
The 2.0L in-line four cylinder engine has the following features:
•Dual overhead camshafts
• Four valves per cylinder
• Aluminum cylinder head
• Aluminum cylinder block
Operation
The 2.0L engine utilizes 4 valve-per-cylinders and a dual overhead camshaft design. The engine uses an individual
coil ignition system. The cylinder block is made of aluminum and the bearing caps are integrated into the lower cyl-
inder block assembly. An aluminum oil pan bolts to the bottom of the lower cylinder block. The camshafts are
mounted in the cylinder head and act against valve tappets to open and close the valves. The camshafts are driven
off the front of the cylinder head by one timing belt. The belt is driven by a sprocket that is located on the crankshaft.
The piston assembly is an aluminum piston with a cast iron connecting rod.
The aluminum cylinder head contains dual overhead camshafts with 4 valve-per-cylinder construction. The valves are
arranged in two in-line banks. The cylinder head incorporates powdered metal valve guides and seats. The cylinder
head is sealed to the block using a multi-layer steel head gasket and retaining bolts.
