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.

Lubrication System
The engine lubrication system operates as follows:
• Oil is drawn into the oil pump through the oil pump strainer tube in the sump of the oil pan.
• Oil is pumped through the oil filter to the cylinder block.
• Oil enters the main oil gallery where it is distributed to the crankshaft main journals and to the cylinder head.
• From the main journals, the oil is routed through cross-drilled passages in the crankshaft to lubricate the con-
necting rod bearings. Controlled leakage through the crankshaft main bearings and connecting rod bearings is
slung radially outward to cool and lubricate the cylinder walls as well as the entire connecting rod, piston and
piston ring assembly.
• The lubrication system is a fully force-fed, full-flow filtration type. The oil pump is a gear type which is driven by
the crankshaft via the timing belt.
