CAT® C3.4B DIESEL ENGINE
Cat® C3.4B Industrial Diesel Engines offer the perfect balance of durability, fuel efficiency and low emissions. Extensively tested on the job, these engines use a range of high pressure common rail fuel systems and advanced control systems to deliver maximum uptime in the harshest environment. They have proven they can handle the toughest applications and deliver superior performance that exceeds the expectations of the most demanding users.Industries and applications powered by C3.4B engines include: Agriculture, Aerial Lifts, Aircraft Ground Support, Bore/Drill Rigs, Chippers/Grinders, Compactors/Rollers, Compressors, Construction, Forestry, General Industrial, Irrigation Equipment, Material Handling, Mining, Mobile Earthmoving Equipment, Mobile Light Towers, Mobile Sweepers, Paving Equipment, Pumps, Specialty Ag Equipment, Trenchers, Turf and Landscaping and Underground Mining Equipment.C3.4B engines, with ratings: 45-55.4 bkW (60-74.3 bhp) @ 2200-2500 rpm, meet U.S. EPA Tier 4 Final, EU Stage IIIB emission standards. Ratings: 63-90 bkW (84.5-120.7 bhp) @ 2200-2500 rpm meet U.S. EPA Tier 4 Interim, EU Stage IIIB emission standards and are designed to meet U.S. EPA Tier 4 Final, EU Stage IV emission standards. This information about Emissions describes the particular rating's emissions technology. For more information about emissions certification, please contact your local Cat dealer.
