KOHLER, Wis. – Oct. 25, 2011 – Kohler® Engines, along with Italy-based Lombardini, a KOHLER® Company, unveils today two new Tier 4 Final emission- compliant, heavy-duty diesel engines for the industrial, constructions and agricultural markets. The KOHLER® 1.9 Liter KDI1903TCR and the 2.5 Liter KDI2504TCR engines offer optimized fuel consumption, limited emissions, and remarkable performance without the use of a diesel particulate filter (DPF).
“KOHLER is expanding its power range offering with some very innovative solutions,” said Dick Fotsch, president of Kohler® Global Power Group. “The power and torque of these engines in relation to their compact sizes and reduced fuel consumption have clear advantages to construction, industrial and agricultural equipment manufactures and end-users.”
Simple Tier 4 Final Emission Compliance
Achieving Tier 4 Final emission compliance without a DPF was possible through the efficient use of the engine’s components, including Kohler’s direct injection system, cooled exhaust gas recirculation (EGR) and diesel oxygenated catalyst (DOC). “Kohler has applied some tried-and-true technologies from the on-road diesel marketplace,” added Fotsch. The high pressure common rail system (CSR) utilizes pressures at 2000 bar (29,000 PSI) resulting in better atomization of the fuel, improved fuel consumption and a reduction in emission particulates. The CSR, combined with the fuel mapping program and other systems, makes for improved exhaust emissions and Tier 4 Final compliance. “The lack of a DPF is a real breakthrough for engines at these displacements, and the technology systems built into the
engines by Kohler and Lombardini are what makes them truly innovative at this power range,” said Fotsch.
The same technology that makes the KOHLER® KDI diesel engines Tier 4 Final emission compliant is also what makes the engines a money-saving alternative for original equipment manufacturers and owners. The compact size of Kohler’s new diesel engines offers increased compatibility and will fit existing and new equipment designed by manufacturers.
There is no shortage of power built into the efficiencies and savings of the new KOHLER® KDI diesel engines. The 1.9 Liter KDI1903TCR has 42kW or 56hp of power at 2600rpm and 225Nm or 166 ft. lbs. of torque at 1500rpm. Kohler’s 2.5 Liter KDI2504TCR has a power density of 55kW or 74.3hp at 2600rpm and 300Nm or 221.3 ft. lbs. of torque at1500rpm. The engine’s mapping program within the Electronic Control Unit (ECU) monitors and manages the engine’s power output in varying conditions by injecting fuel multiple times into the combustion cycle to maximize torque and power when needed most.
Other features of the new diesel engines include less noise and vibration making it Kohler’s quietest diesel model, as well as a heavy-duty crankcase for increased durability to extend the life of the engine.
To complete the new engine series, Kohler has also developed mechanical injection versions. The new diesel engines will be manufactured in Reggio Emilia, Italy.
