It was funny reading this. Like this EcoMotors outfit is the only one
doing boxer engines. Ha.
Hi,
There might be a reason...
Boxer engines (water cooled, of all makes) have a reputation for being
hard on headgaskets. That's at gasoline compression pressures (150-175
psi?) so what do you suppose might happen at diesel pressures of 300-400
psi?
Then there's all the other stuff that needs to be beefed up to make a
"good" diesel. It's a bit more involved than just slapping higher
compression heads on a "gas" engine (ask GM how well they did w/ that
approach in the '80s!) A good diesel's gotta start from ground up. But
automotive bean counters don't like that approach if they think they can
avoid it (even at the cost of future problems.)
At the risk of seeming like a dinosaur, may I suggest there's VERY
little in automotive engine design that hasn't been tried, sometimes
much earlier than we'd imagine. Good designs survive, bad ones often get
"revived" under the "I just had this great idea but didn't check to see
if it's been done before" philosophy. However, few of those that were
turkeys the first time turn into eagles the next.
It would be nice if I'm proven wrong this time, as I'm a believer small
diesels are more a part of our immediate future than hybrids and all the
other darlings of the industry today.
