Doosan Compact Diesel Engines deliver best-level performance even under harsh conditions for any applications thanks to a turbocharger with an intercooler and advanced fuel-injection system.
Doosan users benefit from an easy maintainability. A simple aftertreatment without Diesel Particulate Filter (DPF) minimizes maintenance needs, preventive repairs and operating costs. Plus, long intervals between needed oil and filter changes provide another ease of operation.
By analyzing the root cause of customer downtime, Doosan Infracore developed engines robust enough to increase the uptime and endure the most challenging working conditions.
Innovative Aftertreatment System
Doosan Compact Diesel Engines meet Tier 4 Final emissions regulations with the use of Diesel Oxidation Catalyst (DOC) but without DPF. A non-DPF system contributes to easy and flexible installation, long maintenance intervals and low total life cycle costs. Also, we introduce reliable cooled Exhaust Gas Recirculation (EGR) to reduce up to 95% of NOx.
