- PowerTech E 2.4L models offer full-authority electronic engine controls and air-to-air aftercooled aspirations
- All models include two-valve cylinder heads, fixed-geometry turbochargers and 500-hour oil change intervals
2009 and 2011 Series
The 2009 and 2011 engines achieve Tier III standards via the use of mechanical engine controls and direct fuel injection.
- 2009 Series includes three- or four-cylinder water-cooled engines and a turbocharged four-cylinder version with outputs from 20 to 67 hp at 1,500 to 3,000 rpm
- 2011 family of oil-cooled engines offer rating choices up to 99 hp with low fuel consumption and good cold starting
3TNM68
The 3TNM68 vertical cylinder, four-cycle, water-cooled diesel engine features Indirect injection combustion.
- Three cylinders
- Rated output at 3,600 rpm
800D Series
The 800D range of naturally aspirated and turbocharged, four-cylinder, 3.3-liter engines are tailored to the medium-duty 47- to 62-kW (63 to 83 bhp) off-highway equipment sector.
- 4% increase in power and torque rise over the 800C Series
- Quieter combustion, a redesigned gear train and stiffer timing case reduce vibration and lower noise by over 2 dB(A)
- Same package size and hookups
- Meet Stage IIIA/Tier III emissions legislation
- Increase in top tank temperature minimizes impact on heat rejection
- 500-hour service intervals standard
Compact Diesel Engines
The C0.5 to C2.2 industrial compact diesel engines include 10 models ranging from 11 to 66 bhp and meeting existing Tier 3/Stage IIIA and Tier 4 Interim emission standards.
- Turbocharged and air-to-air aftercooled versions
- Improved electronic-controlled governing
- Redesigned governor assembly and optimization of fuel and combustion systems improve startup and transient capability
- Noise reduction of more than 2 dB(A)
- More efficient cooling and high/low fan position options
E-Series diesel
- The E-Series diesel engine features E-TVCS (three vortex combustion system) technology.
- Offers reduced soot, unburned HC and CO emissions
- Produces less NOx than traditional direct-injection systems
QSB3.3 Engine
The QSB3.3 Tier III engine incorporates full-authority electronic controls and a High Pressure Common Rail (HPCR) fuel system.
- Power range extends from 80 to 110 hp
- Delivers a 30% power boost and a 40% increase in peak torque without impacting fuel consumption
- Precision electronic control of fuel meter and timing for easier cold start, improved idle stability and faster load acceptance
