The Doosan DL06 diesel engine is a turbocharged and intercooled 5.9-liter, in-line 6-cylinder diesel engine used in both on-highway and off-highway applications. The new US Tier 4 Final (Tier 4f) version of the DL06 includes an ultra-low particulate combustion system featuring the Ricardo Twin Vortex Combustion System (TVCS) ; the engine achieves compliance with Tier 4 Final particulate emissions levels without requiring a DPF-thereby providing a cost-effective solution.
The engine features a 4-valve/cylinder head, with a central vertical injector location and high pressure common rail fuel injection system. Typical off-highway applications for the engine are excavators and wheeled loaders, made by Doosan and its subsidiaries such as US manufacturer, Bobcat.
First introduced in 2005, the most recent version of the DL06 diesel engine is certified to Tier 4 interim exhaust emissions regulations, and is equipped with cooled EGR to reduce NOx emissions and a DPF to minimize particulate. With the substantially reduced NOx levels required for Tier 4 Final compliance, Doosan has, like many of its competitors, opted to include Selective Catalytic Reduction (SCR) as part of its aftertreatment technology package.
The ultra-low particulate combustion concept of the new DOOSAN DL06 engine is based on a combustion chamber employing the Ricardo TVCS concept to improve homogeneity of air-fuel mixing, adequate air-fuel ratio at all conditions by balancing the EGR rates and boosting system match, and high fuel injection pressures and appropriate nozzle specification for good atomization.
