FACT SHEET: KOHLER KDI Tier 4 Emission-Compliant Diesel Engine Ling


Ground-breaking industrial/construction engine series delivers significant savings and enhanced performance

KDI1903TCR & KDI2504TCR Engines are Tier 4 Final emission compliant without the use of a Diesel Particulate Filter (DPF) The components of the engines that work together to achieve Tier 4 Final emission compliance:
o Direct injection system utilizing pressures at 2000 bar (29,000 PSI)
o The Electronic Control Unit (ECU), with fuel mapping program to monitor and manage the engine’s power
o Efficient turbocharger
o 4 valve cylinder head with special combustion chamber design
o Cooled, electronic exhaust gas recirculation (EGR)
o Diesel oxygenated catalyst (DOC) Without a DPF, the engines have:
o low cost of ownership
o limited maintenance
o compact sizing for equipment manufacturers
o no heat management issues Direct injection system saves more than $1,400 on fuel and $116 on oil per year when compared to indirect injection diesel engines with diesel particulate filters. Based on 1,000 hours of annual operation at $3.75/gallon of diesel fuel and $4.10/quart of oil.
