Engine Provides power, reliability and acts as a working counterweight in the rear of the machine, for optimum machine balance. Cat C6.6 ACERT™ The Cat® C6.6 is a 6.6 liter (403 in3) displacement, six-cylinder, in-line configured engine that utilizes the Caterpillar Common Rail fuel system for fuel delivery. It uses ACERT™ Technology, a series of Caterpillar engineered innovations that provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. The C6.6 with ACERT Technology offers a compact design with big, heavy-duty engine features for outstanding durability, reliability and performance. The C6.6 incorporates a new cross flow cylinder head design, 4 valve head and an ADEM™ A4 electronic controller. The C6.6 also features proven cylinder block, pistons and crankshaft and incorporates the common rail fuel system. ACERT™ technology enables the C6.6 engine to meet the U.S. EPA Tier 3, European Union Stage IIIA and Japan Ministry of Land, Infrastructure & Transport Step 3 emissions standards, which dramatically reduce nitrogen oxide (NOx) and other emissions. ACERT™ technology used on the C6.6 consists of three basic building block systems: electronic control, fuel delivery, and air management. These have been refined to control the combustion process to a higher degree than ever before possible. Electronic control. ADEM™ A4 The Advanced Diesel Engine Management — Electronic Control Module continuously monitors important engine conditions and functions. It uses sensors throughout the engine to regulate fuel delivery and all other engine systems that require input to manage load and performance. ADEM™ A4 is the brain behind engine responsiveness, self-diagnosis, controlling emissions, and fuel economy. Fuel System Through multiple injection fuel delivery, fuel is introduced in the combustion chamber in a number of precisely controlled microburst. Injecting fuel in this way allows for precise shaping of the combustion cycle. The ADEM™ A4 module directs the injectors to deliver precise quantities of fuel at exactly the right times during combustion cycle. This process provides precise control over a range of combustion variables, which can be regulated to produce higher performance with fewer emissions. Fuel is delivered at high pressure to each combustion chamber through a Caterpillar designed injector linked to a high pressure Common Rail. Air Management Air management is a key concept in optimizing engine ..
