Product Overview: Kubota V2403 Industrial Diesel Engine
The Kubota V2403 is a highly regarded, vertical, water-cooled, 4-cylinder diesel engine at the core of Kubota's durable 03-M Series. Celebrated for its exceptional reliability, fuel efficiency, and clean operation, this engine delivers robust and consistent power for a wide range of demanding industrial and off-road applications.
The V2403 engine family includes several key models with distinct features to meet different power and emissions requirements.
Shared Platform Specs:
The V2403's compact design, strong power-to-weight ratio, and reliability make it a versatile power source for original equipment manufacturers (OEMs). It is commonly found in:
Compact Construction Equipment: Skid-steer loaders (e.g., Bobcat S185, S205), compact track loaders, and mini excavators.
Industrial & Power Units: Diesel generator sets, air compressors, pumps, and wood chippers.
E-TVCS Combustion System: Most models utilize Kubota's proprietary E-TVCS (Three Vortex Combustion System). This technology optimizes airflow and combustion within the chamber, resulting in cleaner burning with lower particulate matter (PM) and significantly reduced noise and vibration compared to conventional diesel engines.
Durable Industrial Design: Built for longevity, the engine block features enhanced cooling water passages between cylinder bores to manage heat from high power density. It also offers practical features like single-side serviceability for easier maintenance and optional side PTOs for driving hydraulic pumps.
Emissions Compliance Flexibility: The V2403 series offers a seamless path through various global emission standards. Models range from Interim Tier 4 to the latest Tier 4 Final and EU Stage V compliant versions, which integrate advanced common rail fuel systems and Diesel Oxidation Catalyst (DOC) + Diesel Particulate Filter (DPF) aftertreatment for clean, high-performance operation.
