I've just bought a nissan 'pickup' (i'm guessing that's what you'd call it because here in australia it's a dual cab ute...) with a QD32 3.2L diesel engine. does anyone know anything about this engine, ie: any fundamental flaws in the engine design problems to anticipate etc...
I my-self had read these forums for a while and have not seen or noticed much mentioned about the diesel. If you dont get a repley answering you question I would recomend these 3 things.
1) Search (I have the american, gas, so I dont know much or similarity between our to trucks so i wouldnt be much help there.)
For alternative information try these other forums.
P.S. I would love to see a diesel in the States. D*** emissions.
LOL As would I . Your gonna be outta kuck on these forums for any real specific data on your enige since we don;t get those here. But I do know that sine they do use such a high compression the diesels are built like a tank and are rated to go over 3000,000 miles without needing any repairs on the internals of the engine. What you call a Dual Cab Ute we call a Frontier and Europe calls it a Navara but America don't get the cools engines like yours. Hope to get a Diesel Nissan as soon as Uncle Sam lets me!!!!!!!!
man i didn't realise you guys don't get diesel over there, what a pain! They're called a navara over here too so i suppose we're more like europe in those 2 respects (name & having diesel engines available)
It is little known that Toyota once made a diesel truck. I bought a new Toyota diesel in 1982.
It was the only lemon Toyota made. They had not designed the transmission properly, had only 4 main bearings when it needed 5. Trans went out at 20,000 miles. Warranty was 12,000 miles, what a mess!
But, the engine ran fine.
I wish Nissan had a US truck with a turbo diesel, that would be a real winner.
Just learned that Nissan had a Diesel engine as an option for the 720.......Nissan will bring diesels back to the US as soon as the low sulfur diesel comes out and the work on a catlytic converter for the diesel exhaust comes to an end. I recently heard the future of automobile engines in America will be hybrid diesel-electric engines due to the already good gas mileage.

I would LOVE to see diesels become more prominent here. There's just one thing stopping them: public perception. Big trucks (semis, and Ford/Chevy/Dodge light duties) run our diesel fuel no problem. Volkswagen diesels run our fuel no problem. We're finally starting to see diesels come back, in the form of many VW diesels, as well as some others, like the new Mercedes E320 (which out-performs the gasoline version), and the new Jeep Liberty, with a 2.8L inline four with common rail direct injection (making 300 lb*ft of torque). But too many people remember Mercedes 300Ds and diesel Oldsmobiles and Buicks smoking up the roads. Those are long gone, and the passenger car diesel engine today is nothing like those were.
I don't call the Aussies and Europeans lucky for having diesels...I call them smart for accepting and embracing them!
I thinks diesels are just about 2 Yrs from becoming big sellers. I have 2 trucks: 93 Hardbody W/3.0L gas & an 03 Ford F350 6.0L diesel. The ford, being a 1 Ton, can carry/tow more, BUT it also gets better mileage. On the Hiway at 65 the Nissan gets @ 17 MPG. The Ford gets @ 18 - 20. The big difference is at 70-75. The nissan mileage will drop like a rock to @15-16, but the Ford will stay right at 17 -18 MPG. At 80 the diesel will still get 16+ on the hiway. At 80 the Nissan gets 13-14. Diesel is still cheaper here on the East coast.

Yeah, diesel is about 20 cent cheaper than the cheapest regular gosoline around here. I have always wanted a V6 turbo diesel for my hardbody. It should have as good a mileage as a small gasoline 4 cylinder but have the torque of a V8 , I would imagine. There are a slew of Nissan diesels(and turbo diesels) that could be brought over from Europe/South America and implimented in the Frontier/Pathy/Xterra line. The CAFE (Corprate Average Fuel Economy) would also be reduced for Nissan allowing for bigger engines and thus bigger Trucks. 4 cylinder diesels would probably get a good 40 mpg in a Sentra or 2 WD Froniter King Cab and would greatly improve the whole product lines reliability and fuel economy. As was mentioned by jadcock the Mercedes diesel clunking around in the 80's wasn't a real good advertisement for the technology and people like their cars quiet and with a "familiar" fuel source. Those are the real reasons that Nissan dropped the hammer on the diesels in the 80's along with a little government pressure to clean the air (a lot of government pressure in California) . Now that car emissions is at the top of the governments list for air pollution, (even though I counted well over 100 semi traliers in a 15 min span on a Sunday going the oppisite direction on the highway with emissions spewing out and no regulation at all for emisssions), a new catalytic converter has to be tested and designed which has to be useable for 10 years without replacement (if I remember correctly) to get a real chance of diesels getting wide avaliability in America. There is one that will reduce diesel emissions now but it is consumed as it converts the diesel exhaust and decreases its catlytic reaction over time to a point of not working at all. If converter is found that will work and isn't consumed then I'm sure the goverment will give the big

I wonder what the VW Jetta types are running? They've been available with TDIs for a few years now. And the trucks (Ford Powerstroke, Chevy Detroit Diesel & Duramax, and Dodge Cummins) have been available with diesels for decades...usually withOUT catalytic converters (like the Over-The-Road trucks). It is hard to compare the particulate emissions of an OTR truck and a light duty truck or passenger car though. In fact, we had an '01 Ford F-550 with the Powerstroke and that was one mean engine...and never any smoke out the tailpipe.
What I personally really like about diesels is the future of organic fuels. Virtually impossible with gasoline engines, you can run 100% organic mixes in diesel engines with very few modifications. In fact, VW has a "kit" that they sell through dealers which enables you do run B100 (100% "bio" diesel). Most commonly, though, B20 is available and can be run with no modifications (B20 is 20% organic, 80% petrol). And just running B20 cuts our reliance on petroleum by 20%! Biodiesel also drastically cuts the hydrocarbon emissions and particulate matter in diesel engine exhaust. Arguments are made that the top end is also much better lubricated when using biodiesel. The biggest drawback to biodiesel is a slight increase in NOx emissions...about 6% when running B20 I think.
I just can't wait for diesels to make their comeback here. When mated with a light-pressure turbo, you get V8 torque (300 lb*ft in the new Liberty) out of a 4-cylinder engine...and making 4-cylinder fuel economy. With more R&D in this area, perhaps we'll happen upon DOD systems (Displacement On Demand) for diesels. In GM cars, this means turning an inline-6 into a 3 or 4 cylinder during cruise operation by turning off certain cylinders. Chrysler calls their system MDS, or Multiple Displacement System. Pair that technology with a diesel and you're looking at fuel economy numbers BETTER than hybrids, with the power and torque to pull the 6000-lb travel trailer.
I think 2006 is the deadline for the low sulpher diesels. I've wanted a diesel pathfinder since I drove one in Europe two years ago. The torque on such a small displacement is awesome (as is the mpg figure).
There's a new passat TDI with a 2.0 though it has the torque of a 4.3 Chevy and the mpg is double.
Here's something for you guys to drool over, check out the v10 VW Toureg - 500+ lb/ft of torque, 300+ HP ~25mpg highway, ~18 city, ~7000lb towing capacity.
Quote "a new catalytic converter has to be tested and designed " the newer Ford diesels have a catalytic converter. Ford also had an investment with Navistar for a V-6 diesel for the 1/2 ton (F 150) trucks, but dropped development. The first one out in a 1/2 ton with the V-6 diesel will take a lot of market share. Once you've driven a diesel truck you don't want to go back to gas.

I think the main problems for the cat is the sulpher, supposedly thats what clogs them.

Ditto that! I'd prefer to have a turbodiesel vs. gasoline engine in everything I drive. I think we're going to be getting a Chrysler minivan soon, and I'm disappointed that you can order a diesel version everywhere BUT HERE.

but we do get to have the 350 Z engine in the next version of the Frontier so I give that a
