AUBURN HILLS, Mich.,
Nov. 12, 2019 /PRNewswire/ --
- New EcoDiesel delivers best fuel efficiency and driving range
ever in a Jeep® Wrangler
- 442 lb.-ft. of torque improves driving performance on- and
off-road
- 3.0-liter EcoDiesel engine available across Jeep Wrangler
four-door lineup
- Diesel-powered Wrangler offered for the first time in
North America in response to
overwhelming consumer demand
The most capable SUV ever will soon be available with the most
fuel-efficient and highest torque-rated Wrangler engine ever with
the introduction of the new 2020 Jeep® Wrangler EcoDiesel. The
expected fuel economy ratings will deliver the highest driving
range on one tank of fuel ever for Wrangler.
Wrangler four-door models will offer the new 3.0-liter EcoDiesel
V-6 engine, rated at 260 horsepower and 442 lb.-ft. of torque, with
engine stop-start (ESS) technology standard. To handle greater
torque loads, the EcoDiesel V-6 connects to a newly added
TorqueFlite 8HP75 eight-speed automatic transmission, calibrated
for low RPM shifts and the on- and off-road rigors of Jeep Wrangler
duty. There are more than 40 individual shift maps to optimize
shift points for fuel economy, performance and 4x4
capability.
"One of the most common questions consumers have asked us over
the last few years has been, 'will you please offer a Jeep Wrangler
diesel?', and I'm pleased to answer that with a resounding,
'Yes!'," said Jim Morrison, Head of
Jeep Brand – North America. "I
recently drove the new Jeep Wrangler EcoDiesel on the Rubicon Trail
and can unquestionably attest to its incredible off-road
capability. Combining that unmatched off-road capability with the
vehicle's fun-to-drive on-road performance, best-ever Wrangler fuel
economy and incredible driving range underwrite the fact that our
customers knew exactly what they were asking for."
All Jeep Wrangler EcoDiesel models – Sport, Sahara and Rubicon –
feature third-generation Dana 44 front and rear heavy-duty axles.
Additionally, all Wrangler EcoDiesel models feature a 3.73 axle
ratio. Two transfer cases are offered: the Rock-Trac two-speed
transfer case with a 4.0:1 low-range gear ratio on Rubicon models
and the Command-Trac part-time two-speed transfer case with a
2.72:1 low-range gear ratio on Sport and Sahara
models.
The 2020 Jeep Wrangler EcoDiesel goes on sale in the fourth
quarter of 2019.
All-new EcoDiesel engine
The third generation of the turbocharged 3.0-liter EcoDiesel V-6
engine delivers increased torque and horsepower, along with superb
fuel economy and minimal levels of noise, vibration and harshness
(NVH) to meet the needs of Wrangler customers.
Several significant changes contribute to the new EcoDiesel's
improved dynamic and fuel economy performance:
- A new-generation water-cooled turbocharger with variable
geometry turbine (VGT) and low-friction bearing increases
efficiency and responsiveness during transient conditions
- Redesigned cylinder head intake ports with higher flow
capability improve swirl and flow, increasing performance and fuel
economy
- The exhaust gas recirculation (EGR) system design has been
updated to a dual loop (low and high pressure) system. The added
low-pressure circulation system draws gases after the diesel
particulate filter, thus minimizing turbocharger energy losses,
which increases fuel economy
- The compression ratio has been optimized to 16.0:1 from 16.5:1
to improve fuel economy and reduce engine noise
- High-pressure (29,000 psi/2,000 bar) direct-injection fuel
injector nozzles were redesigned to match the newly designed and
optimized combustion chamber, reducing fuel consumption
- Lightweight aluminum alloy pistons were completely redesigned
to include thinner rings and low-friction diamond-like carbon
coating on the pin and compression piston ring to reduce parasitic
losses
- NVH has been improved by offsetting the piston pin 0.3
millimeters from the centerline
- The lower portion of the two-piece oil sump uses a lightweight
sandwiched polymer/metal material, which further reduces NVH
- The dual vacuum pump system uses electric and a new mechanical
low-friction pump with new blades that improve overall system
efficiency
These upgrades build on the EcoDiesel V-6 engine's previous
success, the attributes and performance of which made it a winner
of "Wards 10 Best Engines" for three consecutive years (2014, 2015,
2016).
The 3.0-liter EcoDiesel V-6 uses dual overhead camshafts (DOHC)
with four valves per cylinder and a 60-degree angle between the
cylinder banks. The block is cast with compacted graphite iron,
which provides strength to dampen vibrations, but weighs less than
gray cast iron. A compacted graphite iron bedplate adds rigidity to
the block.
The EcoDiesel V-6 engine uses a forged steel crankshaft and
connecting rods for strength and durability. The aluminum alloy
pistons are cooled on the underside via oil jets. Heat-treated
aluminum cylinder heads use individual bearing caps to reduce
friction and minimize NVH. The chain-driven overhead camshafts
employ roller-finger followers.
The diesel engine's turbo Charge Air Cooler (CAC) is located at
the base of the grille, in front of the radiator, to maximize
cooler temperatures. The CAC uses the same mounting position as in
the four-cylinder gasoline turbo engine, helping to reduce
complexity.
A new 5.1-gallon diesel exhaust fluid (DEF) tank is located
immediately behind the fuel tank with refill location next to the
diesel fuel filler. DEF refills align with oil changes lasting up
to 10,000 miles. Levels are monitored via a new DEF gauge in the
front cluster.
The 3.0-liter EcoDiesel V-6 engine is produced at the FCA Cento
facility in Ferrara, Italy.
