EPA approves Caterpillar’s entire 2004 engine lineup

Caterpillar announced that it has become the first engine manufacturer to have its entire 2004 engine lineup certified for the Environmental Protection Agency’s 2004 emissions standards.

The 2004 standards require manufacturers to demonstrate 2002 emissions levels for nearly double the miles of operation in heavy-duty on-highway truck engines. Cat’s C7, C9, C13, C11 and C15 engines all meet these impending regulations.

The final engine to get the EPA’s green light for 2004 was the C11, which is popular among vocational truck customers.

ACERT technology reduces emissions at the point of combustion and is comprised of engine electronics, fuel injection systems and aftertreatment systems that work collectively to reduce emissions. All 2004 Cat engines will feature ACERT technology.

  • I am applying for a grant to update our Semi-Trucks. We have a 2004 Catepillar Model C15, Serial Number MBN29407. Can you please email me the Emmissions data for this particular engine? I need to compare it to a newer Low NOx, engine to show the savings?

    Please advise.
