What is Chrysler MultiAir?

MultiAir is a computer-controlled electrohydraulic inlet valve lift and duration control system. It offers the same advantages as BMW’s well-known Valvetronic system, but is even more flexible, as it’s able to control individual cylinders.

What does a MultiAir actuator do?

MultiAir is a hydraulically-actuated variable valve timing and variable valve lift engine technology enabling “cylinder by cylinder, stroke by stroke” control of intake air directly via a gasoline engine’s inlet valves.

Is MultiAir reliable?

Registered. Agree with what has been said above – MultiAir itself is reliable enought to last. Just you need to follow regular oil changes and correct oil specs. Had couple of cases on Giuliettas (not avalable in US) with failed MultiAir cassette/module – failure of solenoids.

Is the 2.4 MultiAir a good engine?

Chrysler 2.4 inline-4 engines are solid engines, overall. They might not offer much power or performance (apart from SRT-4 versions), but they do offer a good blend of reliability, efficiency, and longevity. However, no engine is perfect and that applies to the 2.4 World Gasoline & Tigershark engines.

Is the 1.4 MultiAir a good engine?

The FPT 1.4 Turbo engine, the first Fiat power unit to incorporate revolutionary MultiAir technology, has won the prestigious Engine of the Year award in the Best New Engine of the Year category.

How long will a 2.4 Tigershark engine last?

Whether it is the Tigershark, or the Pentastar, 200 or 300k miles on these engines should be easily achievable as long as regular maintenance is performed.

Why does the 2.4 Tigershark burn oil?

But a defect in the Tigershark engine means the piston rings don’t work correctly with the cylinders. This allows oil to seep past and burn off in the compression cycle. As the engine loses oil, excess heat and friction will prematurely wear down internal components.

Why do Tigershark engines burn oil?

Control rings at the top of the piston sidewall prevent oil from entering the combustion chamber but a defect in the Tigershark engine means the piston rings don’t work correctly with the cylinders. This allows oil to enter and burn off in the compression cycle.

Do all Tigershark engines burn oil?

The 2.4L Tigershark engine consumes a quart of oil every 1,000 miles. Defective control rings allow oil to sneak past into the combustion chamber. The automaker has been sued after maintaining their stance that this level of consumption is “normal.”

Is the Tigershark engine good?

It’s now known as the 2.4 Tigershark. These engines offer anywhere from 172-285hp, which is reasonable performance for the small design. They also offer solid efficiency and reliability. However, no engine is perfect and that applies to the 2.4L inline-4.
