What makes a dual overhead camshaft a DOHC?
What makes a dual overhead camshaft a DOHC?
Generally, engines with dual overhead camshafts (DOHC) are higher performance engines, they produce more power, and can run at higher speeds. The camshafts have the job of opening the valves that let air into and exhaust out of the engine. The camshaft uses rotating lobes, called cams, that push against the valves to open them.
What does it mean to have an interference engine?
An interference engine is one that has insufficient clearance between the valves and pistons if the cam stops turning due to a broken timing belt. The result is usually catastrophic engine failure. Not so with a non-interference engine. It pays to know.
When did the 2.4 liter engine come out?
The 2.4 Liter Four-Cylinder Engine The Chrysler-engineered 2.4 liter four-cylinder entered production in December 1994 for minivans and cloud cars, essentially a long-stroke 2.0-liter Neon engine. While the Neon engine was criticized for being loud and somewhat uncouth, the 2.4 seemed to be quieter and gentler, and gained many fans.
What’s the difference between a 2.0 and 2.4 liter engine?
Compared with the original 2.0, the 2.4 had a longer stroke, taller block, dual overhead camshaft cylinder head (optional on 1995-99 2.0 engines), and dual counter-rotating balance shafts to reduce engine vibration.

Is the Dodge Caravan 2.4 L engine out of service?
FWIW, these two Chrysler V6 engines are well known for delivering an easy quarter of a million miles with nothing more than basic maintenance (they don’t even need timing belt changes as they use a timing chain). Might you elaborate on the circumstances of its “out of service” status?
Is the Chrysler 2.0 engine interchangeable between 2002 and 2003?
For this reason, these engines are generally not interchangeable between the 2002 (and prior) and 2003 (and newer) model years. Up to late 1999, this engine type suffered from oil leaks and head gasket failures between the block and cylinder head.
How much horsepower does a Chrysler ECC 2.0 have?
The shorter runners are also opened at wide-open throttle below 3000 rpm to provide an intake path to each cylinder that is as free-flowing as possible. The DOHC ECC 2.0 produces 150 hp (112 kW) SAE at 6500 rpm with 133 lb⋅ft (180 N⋅m) of torque at 4800 rpm. It has a cast iron engine block and aluminum DOHC cylinder head.
