Cat’s heavy-duty C13 and C15 (shown), should be EPA-certified by year’s end.
Caterpillar has officially launched its ACERT (Advanced Combustion Emissions Reduction Technology) engines. The company claims the technology meets clean air standards without the use of exhaust-gas recirculation (EGR). ACERT will be available across Cat’s product line by the end of the year.
The engines feature a double turbo system, an air management system designed for maximum combustion efficiency, a new fuel system and new electronics. It also employs an exhaust aftertreatment system already in use on other Cat engines.
The engines will weigh between 150 and 200 pounds more than the company’s present engines, and they will cost more, but the company says they will achieve fuel economy comparable to its 2001 engines.
Cat will build five ACERT engines: the C7, for mid-range use; the C9 and C11, for vocational operations; and the C13 and C15, for heavy-duty trucks. The C7 and C9 have already received Environmental Protection Agency approval and others will be certified before the end of the year, according to Cat.
