The engine uses the latest technologies to optimize fuel economy, improve control and accuracy, and reduce environmental impact.

The common rail system (CRS) optimizes fuel economy and reduces operating costs. High-pressure injection atomizes fuel into finer particles which burn more completely. It results in improved fuel economy and a lower cost of operation.

The electronic control unit (ECU) provides optimum fuel control and accuracy. ECU monitors and controls the engine. It continuously monitors engine conditions and adjusts the fuel delivery accordingly to ensure optimum performance and emissions.

The engine comes with an aftertreatment system. The system operates automatically. The exhaust filter consists of a diesel particulate filter (DPF) which captures particulate matter (PM) contained in the exhaust gas. Using a natural cleaning process, most of the PM trapped in the exhaust filter is eliminated by the heat of the exhaust stream generated by normal use. In situations of low temperature, engine speed or load factor, an active cleaning cycle is initiated. In this cleaning cycle, the exhaust gas temperature is raised by injecting additional fuel during the exhaust stroke of normal vehicle operation to the diesel oxidation catalyst (DOC).

• After many hours of use, the exhaust filter may require an ash removal service.

Depending on the load that the tractor is under, as well as ambient temperature, humidity, and engine speed, the DPF may build up with particulate matter, thus requiring cleaning. Filter cleaning is determined by one of three conditions:

• A prescribed time-based estimation of needed filter cleaning

• DOC/DPF pressure sensors

• A particulate matter buildup estimation based on load conditions

Once one of the three conditions have been met, filter cleaning will occur. There are three different types of filter cleaning processes:

• Passive filter cleaning

• Active filter cleaning

• Parked filter cleaning

Passive filter cleaning occurs naturally when the engine is generating enough heat to oxidize particulate matter. This automatic process occurs continuously during normal operating conditions. No tractor icons or symbols appear on the display during passive filter cleaning.

NOTE: Passive filter cleaning requires no operator involvement, and there is no interruption to tractor operation.

If conditions (temperature, load, or speed) for passive filter cleaning cannot be achieved, then particulate matter is removed using active filter cleaner.

To achieve the required conditions, exhaust temperature management (ETM) manages the initiation and duration of active filter cleaning.
