Re: Volvo Disel (onefastvolvo)
As others pointed out, Volvo did sell some diesel cars in the USA in the Early to mid 1980's. The 1st car to get one was the 260. That was a 6 cyl 2.4 engine that was sourced from Audi. That car was a complete DOG when it came to driving. Acceleration was increadibly slow, to the point where you'd have a hard time getting up to speed on a highway on-ramp. The 760 Turbo Diesel on the other hand was a completely different beest. With the addition of a Turbo, the diesel engine was transformed into quite a peppy car. There was some serious tubo lag when to accelerated off the line. The first second or two the car would more kind of slowly. As you hit around 3000 RPM, you'd hit the power band and the car would take off like a rocket. It was never as fast as the Turbo Intercooled Gasoline engines, but it was significantly faster than the B23/B230. Once you were cruising and the engine's high torque made for a wonderful highway cruiser. Winter starting wasn't bad. We only once had the diesel gell in the fuel filter. I can an extension hose outside and put and pointe a hair drier at the fuel filter. Within a little while I was able to get the car started again. We also had an '81 Old with the huge 5.x liter diesel engine. Though that car could get an amazing 30 MPG on the highway, getting that pig started in the winter at times would take TWO additional cars in addition to the two batteries it had. The Volvo diesel was much easier to live with.
One problem that we experienced (twice) and that I later found out was not unusual was the oil starvation problems. Our mechanic explained to me that the oil was delivered at one end of the engine and it had to cascade to the other end. This caused some oil starvation during startup. This design worked fine for VW/Audi in the 4 cyl and 5 cyl version of this engine, but with 6 cylinders they realy should have had the oil delivered to the middle. If you drove a lot of short distances you tended to trash the engine around 100,000 miles. If you drove the car all day long, the engine could easily last 500,000 miles. I know there was a guy in Maine who specialized in overhauling these engines and did some minor modifications to help make the engine better. This same diesel expert also pretty much insisted on using Mobile 1 synthetic oil. With the changes he made and the extra protection of synthetic oil most of the early engine deaths could have been prevented. Sadly I found out about this after we wore out the 2nd engine.
The USA never saw the D24TIC, the Intercooled version of the D24. The Intercooler just like with the gasoline Turbo cars that Volvo was then making realy helped up the power output and also dramatically lowered intake temperatures thereby further reducing engine stress and make it a better, longer lasting engine. By the time that engine was ready, GM had done enough damage with their diesel engine to convince most Americans that diesel cars sucked. In case you don't know GM took a Gasoline engine design and "upgraded" the block so that it could be used with Diesel... histroy shows that it was a VERY bad design move. Strangely we actually have very little trouble with our GM diesel engine... it was the transmissions that would be completely trashed after 50 to 60K that had my dad completely steaming mad at GM. When he talked to GM to complain they told us we were getting above average life out of our transmissions. Needless to say that was the last GM they ever owned.
Happy Swedish Motoring,
