Next Honda Accord to hit 60 MPG - report
Autocar reports a mileage of 62.8 MPG for the European Accord 2.2l CTDI
as tested at the recent Diesel Technology Forum Tour
in Sacramento,
California. A similar performance of 59.46 MPG was achieved on the E320 CDI
world record drive from Texas to Florida in 2005
(earlier mention).
Both numbers are based on the larger UK Imperial gallon and highway
driving. Honda's European specs are 5.5 liters per 100 kilometers,
combined, in the NEDC, which converts to 43 MPG in US numbers,
and is higher than for the Accord V6 hybrid, which will
be replaced by the diesel. Honda plans to use an innovative
combined particulate and nitrogen oxide converter producing ammonia
to clean the exhaust. (tip Doug Hetrick)

Mercedes to show S-Class Bluetec study with 36 MPG
Auto Motor und Sport reports Mercedes will
show a Bluetec S-Class concept at the IAA later this year with consumption
lowered to 6.6 liters per 100 kilometers. To achieve this number
the car will likely use a four cylinder diesel, suggesting the new
OM651 with twin turbocharging and 204 hp. Automatic stop-start and
brake energy regeneration contribute to the efficiency. Since
four cylinder engines have not been used in the S-Class before
series production is questionable and would start in late 2008 at
the earliest. Emissions are said to already comply with Euro 6 limits
which become effective in 2014. This S-Class Bluetec concept is similar
to the S320 Bluetec Hybrid shown at the IAA in 2005
(earlier mention), and might
also have been inspired by the "Auto 2000" research vehicle with biturbo
V6 diesel which Mercedes showed 26 years ago at the IAA in 1981, and which
burnt only 7.5 liters per 100 kilometers. It pioneered a light-alloy V6 diesel
engine with two-stage turbocharging.

MAG wins four major orders to machine CGI cylinder blocks in North America
MAG Industrial Automation Systems already
received
four major volume production orders for machining lines to process
compacted graphite iron (CGI) V-diesel engine cylinder blocks
from OEMs in North America, Ford, Cummins, International and GM.
Diesels were forecast to become the dominant
engine for pick-up trucks and SUVs in North America and the majority
will rely on CGI cylinder blocks, which can provide a weight reduction
of 100 to 120 kg over conventional grey cast iron. Start of production
is planned during 2008. The blocks are cast at Tupy SA in Brazil
before being shipped north for machining.
The first CGI engine blocks from Tupy were for the Audi V6 turbodiesel
starting in 2004. They also supply Jaguar, Landrover, MAN, VM Motori
and Volkswagen CGI diesel engine blocks.

Hyundai considering diesel for USA
Hyundai may offer diesels in the USA.
Most likely this would be based on the new
3.0 liter V6 S-engine developed with SeohanWarner Turbo Systems, a
BorgWarner Joint Venture in Korea, who supply the electrically controlled
turbocharger. "The highest priority on my personal wish list is bringing
our diesel technology to the United States, and I'd like to bring that
across all of our products," said Steve Wilhite, CEO Hyundai Motor America,
in an interview at the New York auto show. The HCD-10 Hellion at the recent LA auto show had a 236 hp 3.0 liter V6 turbodiesel with 332 lb-ft of torque. The 60° V6 engine block is cast of compacted
graphite iron (CGI) at the Hyundai foundry in Jeonju. via Doug Hetrick.

Mercedes-Benz Statement in Response to EPA SCR Guidelines
MONTVALE, N.J., -- MBUSA issued the following
statement today regarding the Environmental Protection Agency's
announcement on SCR diesel guidelines:
"Mercedes-Benz welcomes and supports the EPA's announcement on
Selective Catalytic Reduction (SCR) guidelines, which represent a critical
next step for the future acceptance of diesel vehicles in the U.S. market.
This decision, teamed with the Agency's recent mandate for Ultra Low Sulfur
Diesel (ULSD) fuel availability, serves to reinforce diesel's benefit as a
viable alternative to help reduce fuel consumption and ultimately, reduce
oil imports."

Bringing an out-of-state new Mercedes diesel to California
There are several ways according to the DMV. If the vehicle
to be purchased has at least 7500 miles on the odometer it can be registered
in California. A few other exceptions are when a vehicle is stolen when
travelling outside of California, or is destroyed or made inoperative the
replacement vehicle can then be registered, even if it is new with less
than 7500 miles.

Biodiesel from green algae
UC Berkeley spinoff Aurora Biofuels is gearing up a
biodiesel production method which is more efficient and less costly
than conventional methods. Instead of growing
soybeans or rapeseed the process utilizes algal biophotoreactors with
genetically modified strains of Bacillariophyceae or Chlorophyceae.
Several years ago, from 1978 to 1996 algae were researched in the DOE
"Aquatic Species Program" to reduce carbon dioxide emissions from coal
fired power plants. Since the algae showed high biodiesel content of
over 50% after binding the CO2, the idea was borne to utilize them for
biodiesel production. MIT spinoff GreenFuel Technologies develops
and operates algae-based biofuel plants in partnership with power
generation facilities.

New Mercedes-Benz 4 cylinder diesel OM651 for 2010
An alert reader, Doug Hetrick, pointed out the new OM651 world
engine is missing on this page. The new inline four cylinder
diesel was planned and engineered at Mercedes starting in 2003,
to replace several existing powerplants and have around 170 hp
(125 kW) and 400 Nm (295 lb-ft) and meet stringent 2010+ Euro 5
emissions.
Besides a 220 CDI there will likely also be other
versions like a 200 CDI or 180 CDIs with different engine control.
The OM651 will replace the OM646 starting in 2009. This engine is
planned in Europe for the C- and E-Class in a few years
and the Sprinter vans, and hopefully makes it to North America. It will
also replace the VM Motori sourced 2.8 liter diesel in the European
Chrysler Voyager CRD which Magna Steyr currently builds in Graz and
is to be built in St. Louis, MO in the future. Siemens Automation
builds the OM651 production line.

30% better fuel economy and 20% less CO2 emissions. He also pointed
out that biodiesel would use 20% plant based fuel that had been
grown in the USA, not imported from the Middle East.
According to the American government's own figures, if diesel had a
33% share of cars and pick-ups, the U.S. would reduce its oil
consumption by up to 1.4 million barrels of oil per day. That would
mean it could stop importing oil from Saudi Arabia altogether.

EPA ready to set SCR diesel guidelines
According to a recent conference the EPA
is ready to introduce guidelines for the AdBlue urea SCR system by October.
Urea systems have several advantages: simplicity, because
they can be used to meet emission limits in all markets,
cost, since they cost about half as much ($880) as an NOx trap ($1400),
and integration, since the system does not affect engine performance
and can be installed without extensive modifications. The EPA is
concerned what happens when AdBlue runs out and may require a warning
system or a system which disallows refueling vehicles with low AdBlue tanks.
DaimlerChrysler, Ford, GM and other automakers support AdBlue SCR.

the engine plant in Marienfelde and produces 215 hp (160 kW) @ 3800 rpm
and 376 lb.-ft. of torque (510 Nm) @ 1600-2800 rpm and gets an estimated
fuel economy of "19 miles city and 23 miles highway" according to various
press releases. Overall the fuel economy improves 30%.
The JGC CRD is expected at dealers in 45 states in the first
quarter of 2007. Jeep currently offers a diesel in the Liberty but the
engine will be discontinued next year when new diesel standards take effect.

MBUSA announces 2007 diesels with more torque than expected
The new efficient ML320 CDI will have 215 hp
(160 kW) and a whopping 398 lb.-ft. of torque. This translates to 540 Nm,
which is more than the European ML320 CDI with 510 Nm. The new clean
E320 BLUETEC will have 208 hp and 388 lb.-ft. exceeding the 201 hp
and 369 lb.-ft. of the inline six predecessor. Ultra low sulfur diesel
(ULSD) should become available before year end. Have a look at the new
stickers on the pumps. In California low sulfur diesel (ECD-1) has already
been available since 2002 at BP/Arco diesel stations. In a prototype
Mercedes diesel tested by the EPA the E320 Bluetec engine emitted
0.05 +/- 0.01 g/mi NOx very close to the limit of 0.05 g/mi needed
to qualify for Tier 2 Bin 5.
According to MBUSA "the 2007 E320 Bluetec, ML320 CDI,
and R320 CDI do not meet the emissions requirements of California, Maine,
Massachusetts, New York, or Vermont and are not available in these states."

Honda, Cummins, BMW to join clean diesel bandwagon
Within three years Honda plans to introduce a clean 4 cylinder diesel
in the US market meeting Tier 2 Bin 5. A V6 is also planned.
Cummins has been working on 4.2 liter V6 and 5.6 liter V8 diesels with
Bosch piezo electric injectors and they are planned for a truck and SUV
with a GVWR of under 8500 lbs by the end of the decade.
BMW plans to use AdBlue SCR which should take about two years
so their diesels can be sold in all 50 states.
Demand for Diesels Jumped 31 Percent in 2005 and MBUSA talks about the new models
According to various reports 543,777 diesel vehicles
were sold last year, an increase of 31% over the
previous year and 80% more than in 2000. MBUSA explains the diesel's
potential and the new models to be introduced later this year starting with
the ML320 CDI and R320CDI and followed by the GL320 CDI early next year.
At present there are already the Sprinter turbodiesel vans and E320 CDI sedans.

World's cleanest diesel E 320 BLUETEC to be introduced in the USA in fall 06
The system comprises a close coupled oxidising catalytic converter,
followed by an advanced DeNOx catalytic converter, particulate filter
and SCR catalytic converter. SCR with Adblue is planned in 2-3 years
after it passes certification. "BLUETEC is the new blueprint for the
cleanest diesels in the world," says Mercedes. "And while BLUETEC was
developed by Mercedes-Benz, it won't be exclusive to Mercedes-Benz. Of
course, we'll share this technology with the Chrysler Group."
Two different Bluetec systems were introduced. In the E320 Bluetec an
close coupled oxicat, advanced DeNOx catalytic converter and particulate
filter are followed by selective catalytic reduction (SCR). For larger
cars, premium automobiles like the S-Class, and trucks like the Vision
GL320 Bluetec an oxicat and particulate filter are followed by AdBlue SCR.

E320 CDI (OM642) fuel economy tested: 49.5 miles per US gallon
After completing the high speed records in Laredo, the three E320 CDIs
with 3.0 liter V6 turbodiesels OM642 DE30 LA were driven from Laredo to
Tallahassee in Florida. Without stopping to refuel each of the unmodified
CDI models covered a distance of 1039 miles (1672 km). Sport stewards
supervised the test, sealed the 80 liter fuel tanks and verified the average
consumption at the end of the trip. It was 4.75 liters per 100 kilometers
which is 49.5 miles per US gallon or 59.46 miles per British Imperial
gallon. The standard renewable particle filters were tested by the TUV
lateron, and still worked well, even after accumulating all these
miles in the speed world records and fuel economy runs.

Vision SLK 320 CDI Triturbo shown in Geneva
The SLK 320 CDI Triturbo is based on the new V6 OM642 diesel engine,
which achieves new levels of performance thanks to a two-stage supercharging
system. It consists of three turbochargers, of which two are located on the
outside next to the cylinder banks while the larger third turbocharger is
situated in the Vee of the cylinders. At low engine speeds and loads, air
flows through all three turbochargers with the small turbochargers doing
most of the work. When engine speed increases and the flow is continuous,
the large turbocharger takes over supplying the greatest share of the
charge pressure. At the upper end of the rev range at full load, only the
large turbocharger is in operation. The three turbochargers give the
Roadster exceptional performance which is reflected by its self-assured
looks which it shares with the SLK 55 AMG: it takes the car just 5.3 seconds
to accelerate from 0 to 100 km/h while its maximum speed is deliberately
limited to 250 km/h. Figures like these mean that the Vision SLK 320 CDI
Triturbo occupies a special position, even among thoroughbred sports cars.
This is particularly true with regard to its fuel consumption. Despite its
breathtaking performance, the diesel Roadster makes do with a modest 7.5
litres of fuel per 100 kilometres, which translates to 31.4 miles per US
gallon (NEDC combined fuel consumption).
Bosch subsidiary Erphi explains the two-stage charging.

Recommended diesel fuel additive: Liqui Moly 1052
Some Mercedes-Benz diesel engine engineers recommend
to add some two cycle oil to the diesel fuel, in case the
engine runs a bit rough due to a batch or so of poor diesel
fuel quality in remote areas. In this connection
Liqui Moly 1052 is usually mentioned. It reportedly burns clean,
better than the diesel fuel itself, and can also be used on diesel
engines fitted with particulate filter.
Still NO firm M-class diesel schedule for North America. We've been waiting since April 2002.
Mercedes tried but has been unable to get approval due
to strict emission rules. The new engines promise more success
but not before 2006 or 2007, and should be 50 states legal using
a serviceable filter. The OM 648 DE 32 LA in the W211 E320 CDI
at present doesn't fit into the M-Class nor into the E-class 4matic.

AVL introduces EmIQ closed loop combustion control
AVL presents EmIQ, an alternate diesel combustion process.
EmIQ enhances the combustion by optimising it in each cylinder individually
and thus further improves the diesel's good efficiency while also reducing
the emissions by up to 99%.
The technology has already been successfully tested in several vehicles.
A cylinder pressure sensor contributes to the EmIQ process, and is
integrated into AVL's cylinder pressure based engine control system
(CYPRESS®) for closed loop control.

Mercedes BlueTec to use Selective Catalytic Reduction (SCR)
starting late 2006 for MY2007 to meet tough emission
standards for passenger cars in North America. The aqueous AdBlue
solution is supplied by a renewable canister which has to be
changed with every oil change at 13,000 miles. This is a simpler
version of the SCR used in commercial diesel fleets in Europe and
more cost effective than an NOx trap due to a lower fuel consumption
of between 2 to 5%. It's reliable since it can't be damaged as
easily by sulfur in the diesel fuel as for example an NOx trap,
which might not be effective for the mandated 150,000 miles.
Ford and Chrysler are also looking at SCR. Nissan is first to introduce
it to Japan. In 2005 Mercedes-Benz will deliver the first
Actros with SCR, where the SCR catalyst is integrated with the muffler.

Many smaller European diesels to be discontinued after 2010
Many smaller diesel engines can not achieve the new tight EURO 5
emission limits which take effect in 2010 and have the same limits
for gas and diesel engines. Cars like the VW Golf TDI will most likely
have to be discontinued without expensive upgrades using soot particle
filter and NOx catalyst, which may cost more than the engine itself and
also penalise the fuel economy.
"The diesel will not be abolished", predicts VW boss Bernd Pischetsrieder.
"But it will only survive in large vehicles." Last year 40% of all new
vehicles sold in Europe were diesels, up from only 10% in 1990.

regenerates itself by adjusting various engine-control
functions, such as fuel injection, intake-air throttle,
exhaust-gas recirculation and boost-pressure control.
In this way, it is possible to increase the temperature
of the exhaust gas and the particles accumulated in the
filter are burned off. This new SiC based filter is sturdier
than the cordierite based particulate filters Mercedes
used in 1985 California turbodiesels.
