[quote=cchase]Wonder what the advantage of a compression ignition gasoline engine would be? Lower BTU's than diesel anyway.
The manufacturing cost of a gasoline compression engine vs a diesel could be lower in the long run.
It would take an act of G-- to get the majority of Americans to accept diesel.
Diesel vehicles are a niche market and the manufactures charge a fortune for the option. $8315 for an F250, the Cruze and VW's are costly, too.
North America and Europe are almost on different planets regarding diesel engines.
In most of western Europe (I don't know about former Warsaw pact nations) diesel engine cars outsell gasoline models by vehicle volume.
A consequence of this is the premium for diesel power has almost disappeared, indeed in some cases diesel versions are cheaper than gasoline ones. Also diesel fuel is significantly cheaper than gas in France, Germany and the low countries. In the UK diesel is slightly more expensive than gas.
And modern diesel engines have advanced light years from the smokey, lethargic, smelly taxi pack specials current when Oldsmobile launched its ill fated diesel 350.
My wifes Peugeot 307 taxi cab is a fine example, cold starting is almost instantaneous, noise levels are not much greater than equivalent gasoline cars, performance is brisk, and cruising at 70+ mph with a full load effortless, and it returns 42 mpg (imperial).
It's fair to say it's noisier than gas models, but not by much, and the fumes are a bit smelly, but you would have to stand by the exhaust tailpipe for a while to get smelly clothes.
I think some of the reasons diesel hasn't found favour in North America are;
Gas is still cheap. Ok I know it has increased in price hugely over the last 10 years or so, but it is still 30-40% of the price in Europe.
People still have memories of the terrible Oldsmobile diesel of the late '70s-early '80s.
Diesels don't go well with automatic transmissions, although lately this has improved greatly.
Particulate emissions have been a problem too, again big advances have been made in recent years.
Diesels are less tolerant of neglected lubrication maintenance than gas vehicles.
There isn't an infrastructure of shops with trained technicians to look after mainstream cars. A classic catch-22 situation, no cars sold because there is nowhere to take them for service, no point in setting up a diesel repair shop if there are no cars to service and repair.
