The Cat C6.4 with ACERTTechnology introduces a series ofevolutionary, incremental improvementsthat provide breakthrough enginetechnology. The building blocks ofACERT Technology are fuel delivery,air manage
10、ment and electronic control.ACERT Technology optimizes engineperformance while meeting global lowemission regulations. With its proventechnology, robust components andprecision manufacturing, you can counton this engine to power up at start timeand keep working productively allshift long.Performance
11、. The 320D, equippedwith the C6.4 engine with ACERTTechnology, provides a speed andefficiency advantage in high productionapplications. By combining excellentfuel consumption of the C6.4 enginewith the Economy Mode, customers canbalance the demands of performanceand fuel economy to suit theirrequire
12、ments and application.Automatic Engine Speed Control.The two-stage, one-touch control reducessound levels and fuel consumption.ADEM A4 Engine Controller.The ADEM A4 electronic control modulemanages fuel delivery to get the bestperformance per liter of fuel used.The engine management system providesf
13、lexible fuel mapping, allowing theengine to respond quickly to varyingapplication needs. It tracks engine andmachine conditions while keeping theengine operating at peak efficiency.Electronic Control Module.The Electronic Control Module (ECM)works as the “brain” of the enginescontrol system, respond
14、ing quickly tooperating variables to maximize engineefficiency. Fully integrated with sensorsin the engines fuel, air, coolant, andexhaust systems, the ECM stores andrelays information on conditions suchas rpm, fuel consumption, and diagnosticinformation. Fuel Delivery. The Cat C6.4 featureselectron
15、ic controls that govern the fuelinjection system. Multiple injectionfuel delivery involves a high degreeof precision. Precisely shaping thecombustion cycle lowers combustionchamber temperatures, generatingfewer emissions and optimizing fuelcombustion. This translates into morework output for your fu
16、el cost.Cooling System. The ambient coolingcapability of the Cat C6.4 on the 320Dis 52 C (125 F) . This can potentiallylead to better fuel efficiency and longerhydraulic component life in all ambientconditions.4C6.4 with ACERT TechnologyThe CatC6.4 gives the 320D exceptional power and fuel efficienc
17、y unmatched in theindustry for consistently high performance in all applications.Component Layout. To optimizeefficiency of hydraulic performance,the hydraulic components are locatedclose together, which reduces frictionloss and pressure drops in the lines.System Pressure. System pressure hasbeen in
18、creased to 35 000 kPa (5,076 psi),which attributes to improvedperformance: Increased stick and bucket forces(up 7% higher than the 320C) tobetter handle those tight diggingconditions More drawbar pull (206 kN 46,300 lb) to provide more abilityto climb slopes, easier spot turnsand improved travel in
19、poorunderfoot conditions More lift capacity, generally overthe front where you are generallyhydraulically limitedPilot System. The pilot pump isindependent from the main pumps andcontrols the front linkage, swing andtravel operations.Hydraulic Cross Sensing System.The hydraulic cross sensing systemu
20、tilizes each of two hydraulic pumps to100 percent of engine power, under alloperating conditions. This improvesproductivity with faster implementspeeds and quicker, stronger pivot turns.Boom and Stick Regeneration Circuit.Boom and stick regeneration circuitsaves energy during boom-down andstick-in o
21、peration which increasesefficiency, reduces cycle times andpressure loss for higher productivity,lower operating costs and increasedfuel efficiency.Auxiliary Hydraulic Valve. The auxiliaryvalve is standard on the 320D. ControlCircuits are available as attachments,allowing for operation of high andme
22、dium pressure tools such as shears,grapples, hammers, pulverizers,multi-processors and vibratory platecompactors.Hydraulic Cylinder Snubbers. Snubbersare located at the rod-end of the boomcylinders and both ends of the stickcylinders to cushion shocks whilereducing sound levels and extendingcomponen
23、t life.Optional Heavy Lift. The optional heavylift feature on the 320D increases systempressure to 36 000 kPa (5,221 psi),giving even more lift capacity overthe front. Heavy Lift is activated bydepressing the soft switch on the righthand console. As the pressure increases,the engine speed is reduced
24、, which allowsbetter control while lifting objects.5HydraulicsCathydraulics deliver power and precise control to keep material moving.6Caterpillar offers the most intuitive and easy to operate excavators while providing greatall around visibility and exceptional operator comfort.Operator ComfortOper
