Description
The 2.4L in-line four cylinder engine has the following features:
•Single overhead camshaft
• Four valves per chamber cylinder head design
• Aluminum cylinder head
• Cast iron cylinder block
Operation
The 2.4L engine utilizes 4 valves-per-cylinder and a single-overhead-camshaft design. The engine uses an individual
coil ignition system and multi-point sequential injection. The cylinder block is made of cast iron and the bearing caps
are integrated into the lower cylinder block assembly. A cast iron oil pan is located at the bottom of the lower cylinder
block. The camshaft is mounted in the cylinder head and acts against the valve tappets to open and close the valves.
The camshaft is driven off the front of the cylinder head by the 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 a single overhead camshaft with 4 valves-per-cylinder construction. The valves
are arranged in two in-line banks. The cylinder head incorporates powdered metal valve guides and seats. The cyl-
inder head is sealed to the block using a multi-layer steel head gasket and retaining bolts.
