New Wastegate Turbocharger 2005.
new Cummins-powered Dodge Ram Heavy Duty 610 relies on a new Holset
turbocharger to help deliver its industry-leading performance. The
5.9-liter Cummins 610 is fitted with the Holset HE351 turbocharger
which allows the engine to deliver more power and more torque than
before. The new Cummins 610 generates its peak torque of 610 lb-ft
at 1600 rpm, earlier than competitive diesels.
610’s turbocharger delivers more power and torque than previous
having the same envelope size. It is also the first Holset
turbocharger to utilize compressor cover-mounted “command valve”
wastegate technology which provides an additional degree of control
sophistication. Wastegate turbochargers are matched to give good
performance at low engine speed with the valve closed. The command
valve enables override of conventional boost air-controlled
actuation for even better control, improved transient response and
reduced exhaust temperatures and emissions.
Holset MY04.5 turbocharger is being manufactured at both Holset's
U.K. plant and its Charleston, S.C., facility.
