Volvo Unveils 13-Liter Natural Gas Engine for North American Market
http://www.hybridcars.com ^ | Published May 22, 2012 | By Philippe Crowe

Posted on 05/22/2012 1:43:00 PM PDT by Red Badger

Volvo Trucks unveiled last week its plans to launch a 13-liter heavy-duty natural gas engine featuring Westport high pressure direct injection (HPDI) technology. The engine, marketed under the “Blue Power” designation, is scheduled to launch for the North American market in 2014.

The engine’s advanced high pressure diesel ignition technology will provide significant fuel efficiency gains compared with current natural gas products. Combined with the company’s previously announced offering of compressed natural gas (CNG)-powered Volvo VNM and VNL model daycabs, the new engine will provide customers with a complete range of natural gas-powered transportation solutions. Volvo is also testing another fuel that can be produced from natural gas, DME (dimethyl ether), which has the potential to become an attractive alternative for the North American market.

Through advanced high pressure diesel ignition technology – using trace amounts of diesel to ignite the natural gas – Volvo’s LNG engine will deliver a 30-percent fuel efficiency improvement compared with spark-ignition (SI) engines, making it a viable alternative for demanding long-haul applications. The Volvo 13-liter LNG engine will also reduce greenhouse gas emissions by about 20 percent compared with current diesel products.

The engine will accomplish these savings without sacrificing power, torque or fuel efficiency, all of which are critical attributes for on-highway operations. The Volvo Group was the number one supplier of 13-liter heavy-duty engines to the combined U.S. and Canadian market last year, and the same vertically integrated approach that has made Volvo a global powertrain leader is being applied to the development of the new engine. The company’s proprietary Volvo I-Shift automated mechanical transmission also will be available for customers to specify.

North America’s abundant supply of natural gas, and the reduced emissions and minimal aftertreatment CNG engines offer, make the technology an ideal solution for customers operating in localized or closed-loop applications. To meet current demand, Volvo offers the CNG-powered VNM daycab equipped with a factory-installed Cummins ISL G engine.

The company also recently announced that it is operating natural gas-powered VNL demonstrator trucks. The larger, more robust VNL model features a 12-liter Cummins- Westport ISX12 G gas engine. Factory production of the natural gas-powered VNL daycab will begin in conjunction with commercial availability of the 12-liter gas engine in early 2013. These heavy-duty engines feature maintenance-free aftertreatment, requiring only a three-way catalyst to meet EPA 2010 emissions standards.

Nice car, but at $5,000 to 10,000 more cost than an equivalent Jetta diesel, is it worth it?

The $35,000 price noted at the link puts the car in the same range as an Audi A3 tdi, and well above several hybrids, as well.

Just sayin...but it would be great for Ford to introduce diesel to their passenger vehicle line.

I don’t know the compression ratio required to light natural gas, but I would guess it is much higher than diesel compression ratios.

I figure they get diesel fuel efficiency by using diesel to light off the natural gas.

They also don’t say how the natural gas goes into the cylinder, either via a direct injector or through the intake manifold.

I would suspect that detonation could still be a big issue if there are any hotspots in the combustion changer, perhaps from buildup of carbon in specific areas, if the engine sucks in natural gas during the intake stroke.

I’m confused too because imo the gas would ignite before diesel would. If they use, however, hot and compressed diesel gas, then the diffusion of the gas throughout the mixture would make an efficient and complete clean burn as opposed to a localized burn to spread from a single spark point.

Also, you get a bump in efficiency, because you do not have to throttle a engine, you can burn super lean, since the diesel burns and lights the dispersed charge of natural gas, a mixture that probably would not otherwise burn.

Most of our car engines, unless you have one that has a throttle-less direct injection system, lose a gob-smack of energy because the engine is continuously pulling againt the artificial vacuum.

Weird, a little research on google, indicates that natural gas doesn’t like spark ignition at a compression ratio above 11.5:1.

I would not have guessed that..

It will be used for city bus and truck fleets. MARTA, the transit authority in Atlanta, has quite a fleet of CNG buses. They’ve been doing it for years, and are looking pretty smart for having done so at the moment.

There are plenty of decommissioned former CNG Ford Rangers around here, the gas utility uses them. In the past they were converted back to gasoline for resale. Now, I don’t know but suspect there would be a market for them as is. A place to refuel them would be a challenge for most, setting one up in a home garage is fairly expensive.

A pro-American government would incent the opening of public fueling stations and go light on the taxation of it to establish a domestic alternative to Mideast oil. Heck, it’d go light on the taxation of gasoline produced from domestic crude for the same reason. Fungible my a**, loer transport cost, far less potential supply disruption, much more consistent price. Decouple that.

Interesting discussion. However, technology is rapidly changing and what Ford and Volvo does today is obsolete tomorrow. I am in the process of raising capital to start a trucking company the uses hybrid technology to power class 8 tractors. This is a generator powered tractor with a diesel engine assist. It will get at least 24 mpg. Has a fraction of the carbon emissions of what’s on the market today. The prototypes have been built and tested and the results are conservative. Problem we have is getting funding and setting up a supply chain that the competition cannot derail. Bottom line is that tomorrow what I am seeking to do will become obsolete as well.

Gallon for gallon, nat gas will cut mileage by more than 50 percent.
it has to be less than half the price of diesel to make sense.

I saw a 100% electric Frito-Lay truck last week in Northern Va. It was bigger than the usual large size van. It seemed to accelerate the same as a regular truck. What was really strange was coming up along side, there was no noise other than the tires on the pavement.

At Diesel compression ratios the peak cylinder pressure is so high that the voltage to initiate a spark discharge is so great and the amps so high spark plug life is well almost none existent, There has been some research work on using lasers to solve this problem, or as is done in large stationary NG engines of the megawatt class use plasma jet ignition but in the medium speed market i would think plasma jet would be horribly expensive to implement at a firing rate of +1600 hz. The simple solution is to “pilot” inject some diesel right before TDC this pilot fuel lights off and kicks off the stoichiometric NG gas burn, The good thing about NG is no particulates and you can go to stoichiometric mixing rates skip the fancy DPF filters and DOC + NOx after treatments using a simple 3 way conventional catalytic converter is possible if you run stotomietical mixtures.

Auto ignition temperature of natural gas is about twice that of diesel. The diesel is used to light off the NG. That idea has been around for many years.

Perhaps the increases in (thermal, I suppose)efficiency are coming from an elevated compression ratio, and perhaps staged injection to control cylinder pressures.

Seems like an answer to gov’t mandated lower emissions and utilization of a plentiful fuel as the means.

To liberals though, plentiful is bad, as that means lower cost, which means more consumption, and they want to control consumption. So costs will remain high, no matter what.

Yeah that is a little pricey.

VW makes virtually the same engine right here in the US [that can't be sold here]

The Ford engine get slightly better mileage. As I understand, gas taxes are the only source of funding for the highways.[least in Texas] Double the fuel economy, the amount collected gets cut in half. Thus, no highpro diesel engines in the US.

A spark ignition has a single point of ignition that a ‘flame front’ has to spread out from to burn the fuel-air mixture, creating pollutants in its wake, as some fuel does not get completely burned.

Using a compression ignition system, all the fuel spontaneously ignites simultaneously, since pressure is equal in all parts of the combustion chamber, therefore all the fuel is ignited and burned...........

“VW makes virtually the same engine right here in the US [that can’t be sold here]”

Talking tdis, VW sells diesel Jettas, Golfs, Touregs, and Passats here.

And the same or similar engines go into VW Group’s Audis in A3, Q7.

So they do sell them here.

Jettas and Golfs with diesels range from $25,000 to $30,000.
Loaded tdi Passat under $35,000.

So VW, Audi, BMW and Mercedes all sell diesels, made the investment to qualify them for 50 states.

But not a single former Big Three pursues this market. In fact it is very disappointing how few engine options are offered in the US market. Most Japanese/Korean companies have diesel for other markets, but none in the US.

I hope Ford sells the tdi Focus here, but at a reasonalble price premium.

Not the same as these. You can’t get this engine in the US from what I’ve been told.

Mazda has a gasoline engine that gets 70+ mpg they are releasing in Japan. They claim it could be released here but, with much lower mpg due to regs.
