The 1.642-L (100.2-cu in.) displacement, liquid-cooled 3TNV88C-NJT Yanmar® diesel engine provides 22.9 kW ( 30.7 hp) to the 2032R.
The 1.568-L (95.8-cu in.) displacement, turbocharged liquid-cooled 3TNV86T-NJT Yanmar diesel engine provides 27.4 kW ( 36.7 hp) to the 2038R.
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.
PARKED FILTER CLEANING
In some instances where passive and active filter cleaning have not fully cleaned the particulate matter from the system, a parked filter cleaning may need to take place. Most likely, 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. Additionally, when the automatic filter cleaning process has been deliberately interrupted multiple times, or if active filter cleaning has failed numerous times due to a failed component, a parked filter cleaning may be requested. In these rare instances the operator will have to park the tractor and start the filter cleaning process.
The parked filter cleaning process needs to be activated based on usage and operation of the tractor. The process will take approximately 30 minutes. See operator’s manual for more details.
The emissions system on this engine constantly monitors the soot level of the tractor, making sure the tractor is always in peak performance condition. This ensures high performance at all times.
