PEORIA, IL – On Nov. 29, 2006, Caterpillar Inc. received certification from the U. S. Environmental Protection Agency (EPA) for its C13 and C15 engines equipped with ACERT Technology for 2007. This technology positions Caterpillar to meet future EPA emissions regulations and provides a long-term emissions solution for the global on-highway engine market. The new C13 is available in on-highway vocational and heavy-duty line haul configurations for expanded versatility. ACERT Technology relies on four basic systems to lower emissions — air management, precision combustion, advanced electronics, and effective aftertreatment. These four systems work to decrease particulate matter, oxides of nitrogen, and hydrocarbon emissions while preserving the engine’s reliability and durability, which keep owning and operating costs low.
