D1803-M-T-E3B
Kubota

Product Description: Kubota D1803-M Series Diesel Engine
The Kubota D1803-M is a highly versatile and compact 3-cylinder diesel engine, renowned for its durability, fuel efficiency, and smooth operation in demanding conditions. As part of Kubota's Super 03-M series, it delivers reliable power for a wide range of compact industrial and construction equipment, balancing performance with environmental compliance.
The following specifications are based on the Kubota D1803-M-T-E3B model, a turbocharged variant within the series.
The D1803-M engine is a preferred power source for Original Equipment Manufacturers (OEMs) globally, commonly found in:
Compact Construction Machinery: Powers mini excavators (e.g., 4-ton class), vibratory rollers, and skid-steer loaders.
Material Handling Equipment: Used in compact telehandlers (e.g., Kubota's own KTH4815-2 model).
Power Generation: Serves as a reliable prime mover for diesel generator sets.
Agricultural & Industrial Equipment: Applicable for various pumps, compressors, and other stationary equipment requiring robust and compact power.
E-TVCS Combustion System: This Kubota-patented Three Vortex Combustion System creates optimal turbulence in the pre-combustion chamber, leading to cleaner and more efficient fuel burn. The result is lower emissions, reduced engine noise, and minimal vibration for smoother operation.
Compact and Robust Design: Engineered for high power density and long service life, its compact size and relatively light weight facilitate easy integration into space-constrained equipment without sacrificing durability.
Design for Serviceability: The engine layout considers maintenance ease, with key service points often accessible from one side to help reduce downtime and simplify routine checks.
Emissions Compliance: Engines in this series are designed to meet various global emission regulations (such as EU Stage V), providing equipment manufacturers with a future-proof power solution.
