Honda to introduce a new 3.5 liter V6 diesel by 2010

While many domestic and foreign automakers are looking to hybrid technology to improve fuel efficiency across their auto lines, Honda is looking towards the tried and true: diesel engines.

It was reported last month that the next generation Honda Accord would forgo its slow-selling and poor-performing Accord Hybrid with a diesel variant. The oil-burning Honda Accord will feature a 2.2 liter i-CTDi Tier 2 Bin 5 diesel engine along with an ammonia-filled catalytic converter to reduce NOx emissions.

Honda is also poised to make a new 3.5 liter V6 diesel engine available for its larger vehicles including the Odyssey minivan, Pilot mid-sized SUV and the Ridgeline mid-sized pickup truck. The new Tier 2 Bin 5 diesel will first be available in 2010 according to the Japanese Nikkei newspaper.

The engine is said to be 30 percent more fuel efficient than Honda's current 3.5 liter V6 gasoline engine (rated at 17/24, 15/20 and 15/20 respectively in the Odyssey, Pilot and Ridgeline based on 2008 EPA estimates). The new motor is also said to produce 20 percent less carbon dioxide as the 3.5 liter V6 gasoline engine.

Honda's new diesels likely won't come under as much scrutiny for failure to achieve EPA estimates as has been the case with hybrids. Honda knows this first-hand as it recently became the target of a class-action lawsuit regarding poor fuel economy on the Civic Hybrid.

Although component technology is in the hands of the suppliers (of the components), the automaker is in complete control of the engine assembly. You would be severely stretching reality if you claimed that 1 component would make a extremely significant change in the engine assembly's performance (i.e. the world's best turbo will still be limited by the capability of the piston, block, etc. to handle the mean peak cylinder pressure [+ 3 sigma]).

The only way your assumption is true is if the engine assembly is supplied by an outside source. At the moment, the domestic automakers ONLY outsource large diesels (and there are many rumors that most of that even that production will be brought in house).

I am not trying to flame you, but, I do not see it that way (and I spent almost 7 years in engine engineering).

As far as the technology being available, I will agree that it is common knowledge - the components are nearly a commodity. Getting them to work together reliably is a cat of an entirely different color ...

Component technology is mainly what I'm talking about, like the SCR systems needed for modern diesels.

In that case, I agree with you that the technology is in the hands of the supplier.

However, that technology is available from many companies. What needs to be done is well known.

There are very few technical unknowns in spark/compression ignition engines - almost everything has been demonstrated many times in laboratory conditions. The big questions are how to do it cheaply and reliably in mass production.
