Section 33 (2.4L Engine (Service Information)): Description
WARNING: This page is about a different car, the 2017 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
The 2.4 Liter (146 cu. in.) Tigershark in-line four cylinder engine is a single over head camshaft with mechanical lash adjusters and four valves per cylinder design. This engine is NOT free-wheeling; meaning that the pistons will contact the valves in the event of a timing chain failure.
The cylinders are numbered from front of the engine to the rear. The firing order is 1-3-4-2.
The cylinder head is designed with a variable valve actuator assembly (VVAA) that takes the place of a conventional intake camshaft assembly. The cylinder block and cylinder head are cast aluminum. The engine is mounted in the vehicle transversely.
