Power Train ­ Engine The Cat C32 engine with ACERTTM Technology uses advanced engine technology to reduce emissions without after-treatment. The turbocharged, aftercooled 12-cylinder engine has higher horsepower and faster response for superior performance in demanding applications. 4 ® Power Train ­ Transmission The Cat seven-speed power shift transmission matched with the Cat C32 engine with ACERT Technology provides constant power and efficiency over a wide operating speed range for optimal power train performance. [. . . ] Standard ARC electronically controls braking on grade to maintain engine at approximately 1, 950 rpm (adjustable from 1, 850-1, 950 rpm. ARC is deactivated when the operator applies the brakes or throttle. 2500 2000 Engine Speed (rpm) · Superior Control. Automatic brake modulation offers a smoother ride and better control in slippery conditions, allowing the operator to concentrate on driving. ARC increases operating ease, resulting in greater operator confidence with less fatigue. Automatically activates ARC when engine speed exceeds factory preset levels, regardless of operator inputs, to avoid potentially damaging engine overspeeds. Traction Control System (TCS) (optional). Electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. If slippage exceeds a set limit, the oil-cooled disc brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction. Normal differential action provides superior maneuvering and control in slippery conditions. Optional Compression Brake is integrated with Automatic Retarder Control (ARC) to provide up to 35 percent higher downhill travel speed and reduce wear on brake components. 1500 1000 500 0 10 20 30 40 50 Time (Seconds) 60 70 With Automatic Retarder Control (average speed, 1950 rpm) With Manual Retarder Control (average speed, 1730 rpm) · Faster Speeds. ARC allows the operator to maintain optimum engine speeds for up to 15 percent faster downhill hauls and greater productivity. 11 Serviceability Less time spent on maintenance means more time on the haul roads. Servicing Ease. Easy access to daily service points simplifies servicing and reduces time spent on regular maintenance procedures. Enhanced serviceability and extended 500-hour service intervals are designed to increase machine availability and productivity. Engine-overhaul costs are also reduced up to 25 percent. Easy stairway access to engine, air filters, steering hydraulic tank and radiator. Allows convenient servicing to tanks, filters, drains, battery disconnect and engine shutdown. Engine prelubrication provides engine oil pressure prior to engine cranking. This reduces engine dry and cold start wear, and reduces engine component wear. Fast Fill Service Center (optional). Wiggins fast fill service center features high-speed fuel and oil exchange and clustered connections for fluids for fast, accurate servicing and reduced downtime. Extends oil change intervals and reduces waste oil handling by continuously burning oil from the engine oil pan through normal engine operation. New oil is continually added to compensate for oil burned. S·O·S sampling valves speed sampling and analysis reliability.
