Report: Isuzu and Hino to Collaborate on Next-Gen Diesels for Trucks

The Yomiuri Shimbun reports that Isuzu Motors Ltd. and Hino Motors Ltd. will start talks as early as January on a possible alliance to develop next-generation diesel engines for trucks.

Toyota Motor, which recently acquired a 5.9% stake in Isuzu, holds a 50.1% interest in Hino. Toyota is working with Isuzu on light-duty diesels. (Earlier post.)

If they reach an agreement, the two companies will emerge as a powerful competitor in the nation’s truck industry to rival Nissan Diesel Motor Co., which has capital ties with Sweden’s Volvo group, and Mitsubishi Fuso Truck & Bus Corp., which has been incorporated into Daimler-Chrysler group.

“Because our parent company [Toyota] has tied up with Isuzu in the passenger vehicle field, the environment is now ready for us, as a member of the Toyota group, to accelerate cooperation with Isuzu in trucks as well,” [Shoji] Kondo [president of Hino] said.

The main objective of the alliance will be to develop new types of engines to comply with the stringent exhaust emission controls that will come into effect by 2010 in Japan, as well as in Europe and the United States.



I have seen the Future........and it smells like diesel ;-)


I love the smell of Biodiesel in the morning. Smells like....sustainability.

I just read on that the new Cummins V6 and V8 diesels meet 2007 emissions regs and will be in Dodge trucks by the 2009 model year. The future does smell like diesel, and I think I like it. :)


Lets hope future diesels don't smell like current ones.
I have a Euro 3 diesel Espace (2.2 HDi) and it does not smell that good.
It has good performance and milage for a car of its size and weight, but it is not Chanel #5.
So lets hope they can clean them up with Euro 4 and the tier2 bin 5 or whatever it is in the US.
My view is that hybrid plug in diesels are the way to go.
You would use electric drive in congested areas and diesel on the open road where pollution is less of a problem.
The problem is, of course, cost as both diesels and hybrids cost more than current petrol engines, but mass production and experience could help with this.
Diesels are about 40% of the market in Europe and various electric drive mechanisms are popping up all over the place so I am optimistic.
But the main thing is to define the goal (very high MPG and low CO2 emissions (and other pollutants if required) ) and let the market take care of the rest.


How about diesel electric hybrids. Even better fuel economy, possible flexile engine profiles (max fuel mileage to max torque/power), and perhaps a multi kW clean diesel electric generator mode.

I don't recall the title but I read a book several years ago that presented a history of Japanese engines. Hino built a diesel with 80% efficiency. It used ceramic cylinder and piston parts along with turbo-compounding. Diesels which match or exceed fuel cell efficiency may not be that hard to produce.

"So lets hope they can clean them up with Euro 4 and the tier 2 bin 5 or what ever it is".

Yes. It is tier 2, bin 5, and it will already be in effect for most cars and light trucks in CA and four other states in the northeast in January. The crackdown represents a 90% reduction in PM and NOx in just three years. The rest of the country gets these same standards in '08 for most cars and light trucks, and all cars and light trucks in '09.

I would say that these new technologies will really clean up diesel exhaust. The 2007, Mercedes-Benz, E320 BlueTec is probably 60% cleaner burning than the E320 CDI that was sold through most of 2006, and the CDI had to meet some pretty tough PM and NOx standards that got progressively tougher in 2004 and again, 2006. Of course the new mandates on fuel helped make alot of this happen.

My 2006 VW Jetta TDI has the same 1.9 TDI (PD) that is sold in Europe, but has been designed more for emission control than for performance--as it is in Europe. As a result, it has no black smoke that can be seen, even if you are in full acceleration. I've had my friends check. Also, there is no black soot left around the tailpipe on the car. It probably helps that I burn B20 exclusively for fuel. As clean as this VW is, it cannot be produced for U.S. market after December 31, 2006 due to it not meeting 2007 emission requirements. Even if a new common-rail were brought to the U.S. with 1/2 the emissions of the '06, it would still not meet 2007 emissions without employing some type of advanced De-Nox system, like is seen in the BlueTec.

Euro 4 will be tough on PM, but not as tough on NOx. Euro 5 will be just as tough on PM as U.S. mandates, but still not as tough on NOx. High NOx levels, however, contribute nothing to the stench, and so, the new Euro versions will lose the smell as well.

If diesel engineers can succeed at bringing these very clean diesels to the U.S. in a cost-efficient manner, then it will be good for all of us. U.S. and abroad.

I read this article as well. The DoE and Cummins developed and tested these engines.

The 4.2 V6 was tested against a 5.9 V8 and 4.7 V8 gasser in the Durango. Not only did the diesel outperform the gassers, overall, with less cylinders and displacement; but it also got 44% better fuel economy.

The 5.6 V8 went up against the highly-acclaimed, 5.7 V8 Hemi gas engine in the Dodge, 1/2-ton, Ram. The diesel only lost .8 of a second, 0-60 and managed 49% better fuel economy. To put this in real numbers, the Hemi Ram got a real-world, combined fuel economy rating of 14.6, while the 5.6 V8 Cummins came in at 21.7 mpg with 325 hp and 500 lbs of torque.

How can anyone deny the potential of diesel power? As long as we don't squander fuel economy in favor of outrageous, wasteful, unnecessary horsepower--like we have for the last twenty years with gas power--we'll be doing good with diesels.
