In general, the only time a parked filter cleaning will need to occur is when automatic filter cleaning has been disabled for an extended period of time and multiple warnings to engage filter cleaning were ignored or if the tractor has been used during light load conditions. In some instances where passive and active filter cleaning have not fully cleaned the PM from the system, a parked filter cleaning may need to take place. Like passive filter cleaning, active filter cleaning requires no operator involvement, and there is no interruption to tractor operation. It is important to note that at no time is the fuel in the DOC/DPF ignited, and there is no flame within the DOC/DPF.

The fuel turns to vapor and chemically reacts with the catalysts in the DOC to create heat to oxidize the PM. ETM can adjust numerous engine parameters and/or inject a small quantity of fuel into the exhaust stream for a short duration. To achieve the required conditions, exhaust temperature management (ETM) manages the initiation and duration of active filter cleaning. If conditions (temperature, load, or speed) for passive filter cleaning cannot be achieved, then PM is removed using active filter cleaner. NOTE: Passive filter cleaning requires no operator involvement, and there is no interruption to tractor operation. No tractor icons or symbols appear on the display during passive filter cleaning. This automatic process occurs continuously during normal operating conditions. Passive filter cleaning occurs naturally when the engine is generating enough heat to oxidize particulate matter. There are three different types of filter cleaning processes: Once one of the three conditions has been met, filter cleaning will occur. A particulate matter buildup estimation based on load conditions.A prescribed time-based estimation of needed filter cleaning.Filter cleaning is determined by one of three factors: DPF cleaningДepending 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. 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).ДЄfter many hours of use, the exhaust filter may require an ash removal service. In situations of low temperature, engine speed, or load factor, an active cleaning cycle is initiated. 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. The exhaust filter consists of a diesel particulate filter (DPF) which captures particulate matter (PM) contained in the exhaust gas. The engine comes with an after-treatment system. It continuously monitors engine conditions and adjusts the fuel delivery accordingly to ensure optimum performance and emissions. The electronic control unit (ECU) provides optimum fuel control and accuracy. It results in improved fuel economy and a lower cost of operation. High-pressure injection atomizes fuel into finer particles which burn more completely. The common rail system (CRS) optimizes fuel economy and reduces operating costs comparted to engines not using CRS technology. The engine uses the latest technologies to optimize fuel economy, improve control and accuracy, and reduce environmental impact. The 1.568-L (95.68 cu in.) displacement, turbocharged, liquid-cooled 3TNV86T-NJT Yanmar diesel engine provides 27.4 kW (36.7 hp) to the 3038E.
