The new heavy-duty engine
has no designation as yet, but here's most of what's known about it to this point:
In addition to debuting the Perkins 4000 series engines, PSI has updated 11.1-liter, 14.6-liter and 21.9-liter Heavy-Duty engines
, as well as its .97-liter, 5.7-liter, 6.0-liter and 8.8-liter engines.
The focus of this upgrade work has been on the Constant Volume Sampling (CVS) systems, enabling the facility to provide certification testing of heavy-duty engines
for both on- and off-highway applications to the new EPA 40CFR Part 1065 procedure.
- new technical requirements and procedures for assessing the in-service conformity of heavy-duty engine
emission control systems over defined useful life periods appropriate for the vehicle in which the engine is installed; and
According to CTI, City Engines has distribution agreements with Daewoo Heavy Industries (DHI) for its heavy-duty engines
, with the initial engine offering to be the base DHI 11-liter platform outfitted with CTI-designed cylinder heads.
- new technical requirements and procedures for rating the durability of heavy-duty engine
emission inspection systems over a specific period of the defined lifespan
A team of nearly 300 people, including those from financial, design, customer-service and technical backgrounds, helped develop Signature by working with heavy-duty engine
owners and operators.
The heavy-duty engine
will meet EPA Tier 4 Final and EU Stage IV emissions with an ultra-clean aftertreatment system combining the Cummins Particulate Filter with Selective Catalytic Reduction (CPF-SCR).
"Though fuel economy has always been most critical to our end-use customers, with fuel between $4 and $5 per gallon today, it's absolutely critical not just to their success, it's a matter of survival," added Ed Pence, vice president and general manager of Cummins' Heavy-Duty Engine
The Heavy-Duty Engine
market consists of projected production of over 1.3M engines for 2004.
"The buses have now completed 24,000 miles on the road and HCNG technology has successfully proven itself in a commercially available heavy-duty engine
in a real life application," said Westport senior scientist and manager of hydrogen technologies Sandeep Munshi.
