Welcome back to our discussion of engines that are ready for retirement. Last week, we looked at a number of import engines which are getting to be somewhat long in the tooth, so this week we will look at some domestic engines that could use a refresh. You all were quite active in the comments section, and I thank you for your discussion. Before I get started on the domestics, I would like to bring up a point made in the comments section on the last article. That is the fact that, in many cases, older engines tend to be a bit more reliable than modern engines.

The 3. In the Ram, the engine is also rated at horsepower, and lb-ft of torque. The smaller 3. I think we are also looking at six bolt main caps, but at least four bolts, two or four vertical and two horizontal I think the [open area below the oil returns] are oil drainback holes. The feed is at the upper rear of the cylinder on the bank you can see, what appears to be a hole next to the head bolt.

Basic dimensional elementsóbore, stroke, bore-center spacingócarry over, but the engineering team claims greater efficiency, improved torque characteristics, a small horsepower uptick, and better NVH performance. New components include cylinder heads with an Operating range of the variable-valve-timing system has been increased from 50 to 70 degrees to mitigate detonation during hot starts, improving operation of the automatic engine stop-start ESS function. Carried forward from the current V-6, the ESS system has been enhanced with a new high-speed starter motor in order to reduce cranking time and deliver quicker, smoother starts. FCA chose to continue with an upgraded port-injection system, citing added cost and weight as tradeoffs that go with direct injection. Which would be. That would translate to roughly 18 mpg city and just over 25 mpg highway.

All three Chrysler models, the Pacifica, Pacifica Hybrid and , all have a 3. Read below for all of the ways the engines and specs differ from one another.

Murphy Jan 07, In 19 years of selecting the top powertrains, only nine light-truck applications have been recognized. From towing heavy loads to sloshing about at muddy construction sites, a truck engine must be bullet-proof and always ready to run, and its exhaust note needs to be deep and burly, greeting its owner each morning like a strong cup of coffee. The Ram provides the last piece of the puzzle, proving definitively the Pentastar truly is an all-purpose V The torque peak also comes earlier in the Ram, ensuring the driver gratifying throttle response. Chrysler used to have 32 different exhaust manifolds in this segment and now has zero. The all-aluminum Pentastar keeps getting better.

Steven Finlay Jan 04, The eTorque system replaces the traditional alternator with a belt-driven motor generator that works with a 48V cell lithium-ion battery pack. The result: Our judges recorded 21 to 22 miles per gallon 9 to 9. It restarts the engine in half the time it takes for conventional starter-driven systems. In addition to spinning the engine for restarts, eTorque also recaptures energy during deceleration and especially braking to deliver charge to the battery pack. Pickup-truck owners always have wanted payload, towing ability, durability and utility.

The Chrysler Pentastar engine family is a series of aluminium die-cast cylinder block dual overhead cam valve gasoline V6 engines introduced for model-year Chrysler , Dodge and Jeep vehicles. The engine was initially named " Phoenix ," but the name was changed before the official launch due to a trademark conflict; the Pentastar name is derived from the trademark of the former Chrysler Corporation, which dates back to The Pentastar engine currently does not use exhaust gas recirculation ; [3] however, it not only supports the use of the technology but is expected to add it in a near-term engine update. For , FCA released an updated version of the 3. This engine now featured two-stage variable valve lift VVL , a cooled EGR , a new intake manifold , new fuel injectors , and new ignition coils. It also features upgrades to the variable valve timing VVT system, an increased compression ratio These improvements help to increase power as well as efficiency.
