To reply to some earlier posts:
For same displacement, etc, Diesels provide much more torque
than a comparable gas engine, not
horsepower. Torque feeds the bull dog, especially in a truck.
But, for what any engine lacks in power, gears can make it up:
My Triumphs had a lot of low end torque, not much top end horsepower. 3 or 4 gears worked fine.
My Honda has no
low end, all top end. Six gears fix that..
They do get better mileage for same displacement, etc, partly due to diesel fuel's higher heat content than gasoline. Higher compression vaporizes fuel more. allowing more efficiency.
Old Mercedes 4-cylinder diesel sedans, imported to the U.S, without turbos (at least my sister's, I don't recall what model but it was '64 vintage); were slowww
. She hadda pull over to let people pass while she labored up hills in Sonoma County, near Freestone. Ask anyone who had
one. This and slow starting, hard to find fuel gave the diesel a slow start in US.
Please Note: all
diesel sedans, coupes, have turbos in them nowadays. Some trucks, even big rigs, too. There had
to be a reason they did this.
Again, folks: please reference year, make, model. My sister and I are not lying
. Perhaps an '81 VW had all the bugs out (Heard nothing bad about these=!
), but not a '64 Merc.
Like buying the first Daewoo or Kia--bound to be teething pains.
With all using glow plugs, electronic (no longer mechanical) fuel injection, and turbos, they are Great
. Especially since price of fuel went back down. Diesel always used to be cheaper, and it had higher heat content than gas-- with their better mileage,you saved all around.
