FEATURES OF THE DURAMAX 6600 DIESEL V8:
1 A revised and more aerodynamically efficient variable nozzle
turbocharger with an air-to-air intercooler help deliver smooth,
immediate response and lower emissions.
2 The Bosch direct-injection system maximizes power and
efficiency for each pulse of fuel used. The common-rail fuel
injection system uses an advanced electronic controller and
pilot injection for quieter, smoother operation and reduced
emissions. The fuel injectors spray directly onto glow plugs,
providing faster starts and more complete cold-start
performance with reduced emissions.
3 The four-valve-per-cylinder design improves airflow, resulting
in impressive horsepower output and reduced emissions.
4 Oil-spray cooling, cools the bottom of the piston bowl – the
area that produces the most heat.
5 An integral oil cooler provides increased oil cooling and
extended engine life.
6 The forged-steel crankshaft is nitride surface-hardened for
long-term durability. Hot-forged alloy connecting rods are
fracture-split, locking the two pieces together during assembly
for strength and reduced weight.
7 The induction-hardened, deep-skirt block uses cross-bolted
main bearing caps for superior durability.
