[. . . ] 6 ACERT engine delivers more horsepower using significantly less fuel than the previous series engine. 6 ACERT engine features an aftertreatment regeneration solution that requires no operator intervention. The regeneration process automatically starts once the filtering system reaches a certain level  with no interruption to machine performance or the work process. 6 ACERT engine is equipped with an electroniccontrolled high-pressure fuel system that includes an electric priming pump and three-layer fuel hoses to allow the use of biodiesel (meeting ASTM 6751 or EN 14214) up to B20 (biodiesel 20% mixture).

Cat® Grade Control Depth and Slope
Solutions that make work easier and more efficient
This optional system combines traditional machine control and guidance with standard factory-installed and calibrated components, making the system ready to go to work the moment it leaves the factory. The system utilizes internal front linkage sensors  well protected from the harsh working environment  to give operators real-time bucket tip position information through the cab monitor (1), which minimizes the need and cost for traditional grade checking and improves job site safety. It also helps the operator complete jobs in fewer cycles, which means less fuel use. Cat dealers can upgrade the system to full threedimensional control by adding proven Cat AccuGradeTM positioning technologies, including GPS and Universal Total Station (UTS). Cat Product Link
This optional system is deeply integrated into the machine monitoring system and is designed to help customers improve their overall fleet management effectiveness. Events and diagnostic codes as well as hours, fuel consumption, idle time, machine location, and other detailed information are transmitted to a secure web based application (2 and 3) called VisionLinkTM, which uses powerful tools to communicate to users and dealers. 10
Serviceability
Service Doors
Fast, easy and safe access built in
Wide service doors and a one-piece hood (1) provide easy access to the engine and cooling compartments. Both doors and hood feature enhanced hardware and a new screen design to help minimize debris entry. compartments
The pump (2) , radiator (3) , and air cleaner compartments provide ample access to major components and regular service items like fuel and oil filters. The fresh air filter is located on the side of the cab to make it easy to reach and replace as needed. The cartridge-style spin-on housing enables the internal filter to be separated and replaced; the used internal element can be incinerated to help reduce waste. The 320E is an efficient, productive machine that's designed to conserve our natural resources for generations ahead. 8 gal
