Caterpillar Inc. recently announced the introduction of five new Cat Tier 4 Interim/Stage IIIB Technology Industrial engines. The 
models are identified as C13 ACERT, C15 ACERT, C18 ACERT, C27 ACERT and C32 ACERT. The new engines range from 385 -1200 bhp and provide a seamless horsepower range, broad product choices and powerful advantages for Original Equipment Manufacturers (OEMs) of agricultural, construction, mining, forestry and general industrial markets. All engines are also available with an extensive choice of options ideally suited to meet OEM and end customer requirements across a wide range of heavy duty applications.
These Cat engines continue the legacy of durability, reliability, maximum fuel efficiency, low cost of ownership and World Class support provided by the Cat dealer network.
Cat industrial engines, which cover the 175-750 hp-range, are equipped with a robust, fully integrated Cat Clean Emissions Module (CEM) and the Cat NOx Reduction System (NRS). The new package has been extensively tested to provide OEMs with the optimum flexibility for cleaner, more efficient, reliable Cat power. As with all Cat ACERT Tier 4 Interim technology engines, ACERT Technologies are the key enablers to achieve a significant 50% reduction of Particulate Matter (PM) and a 45% reduction of Oxides of Nitrogen (NOx).
The new C13 ACERT is a 12.5 liter displacement engine and delivers 385-475 bhp (287-354 bkW). It develops exceptional
performance with high torque capability of up to 1604 lb-ft (2171 Nm) and is well suited for agricultural combines and rock crushers. It is electronically controlled and features a dependable mechanically actuated electronic fuel injection (MEUI) system and asymmetric turbocharger.
The new C15 ACERT is a 15.2 liter displacement engine and delivers 475-580 bhp (354-433 bkW) and provides improved lower end power density compared to the Tier 3/Stage IIIA configuration. This engine has outstanding torque up to 1958 lb-ft (2655 Nm) to power OEM equipment in the most extreme operating conditions and is used extensively in rock drills, hydraulic power units, and other industrial applications.
The new C18 ACERT is an 18.1 liter displacement engine that delivers 600-765 bhp (448-571 bkW). Depending on power requirements, a single asymmetric or series turbocharger is utilized which maximizes performance. The C18 ACERT is an ideal choice for air compressors, cold planers, trenchers and agricultural applications. Power density for the 765 bhp rating has been significantly increased over the Tier 3/Stage IIIA model and does not require aftertreatment.
The new C15 ACERT and C18 ACERT are built on a common core platform and share similar physical dimensions. This offers
significant value to OEM’s and can lower installation costs for machines by providing multiple power options across a very wide (475 – 765 HP) power range.
The new C27 ACERT is a 27 liter 800-1050 bhp engine and is easily integrated into OEM equipment powered by the Cat Tier 2 configuration or competitive offering. It produces maximum torque of up to 3539 lb-ft and is well suited for biomass grinders, rock drills, heavy duty pumps and other industrial applications. It features side mounted asymmetric turbochargers and a dependable next generation mechanically actuated electronic fuel injection (MEUI) system. It is electronically controlled and delivers world-class performance and fuel economy.
The new C32 ACERT is a 32.1 liter displacement engine producing 950-1200 bhp. The new platform is equipped with side mounted asymmetric turbochargers and is the ideal choice for biomass grinders and rock drills.
Built on a common core platform, the C27 ACERT and C32 ACERT offer OEMs additional flexibility by providing multiple power options (800 – 1200 bhp) from identical base engines. The C27 ACERT and C32 ACERT for industrial applications will not require aftertreatment to achieve Tier 4 Interim emissions.
The addition of these five engines completes the introduction of the Cat Industrial Tier 4 Interim/Stage IIIB line. With over twenty Tier 4 Interim/Stage IIIB industrial engines, Cat again provides a full range of power solutions from 10-1200 bhp for global OEM applications.
