Building on its partnership with the Kubota Group, established in 1991, Saim Industrial has decided to enter the electrified propulsion sector and use EIMA 2024 as the premier platform to launch its first hybrid unit. Saim was founded in 1951 with the aim of providing high-quality components to industry, particularly the automotive and marine sectors. In the engine sector, it later created the Saim Industrial division, specializing in the sale and configuration of engines for various applications; in 1991, it became the exclusive distributor of Kubota engines in Italy. Hence, the choice to use a Kubota “D1105-K” series engine to assemble the first Saim Industrial hybrid unit—a plug-in, integrated system developed to meet the operational demands of compact agricultural and industrial machinery.
The mechanical foundation of the system is a naturally aspirated, three-cylinder, 1,123 cc engine with indirect injection, delivering about 25 horsepower at 3,000 rpm. This engine meets Stage V emission standards without needing exhaust gas after-treatment systems and comes with a pre-mounted and pre-wired electronic control unit, which speeds up and simplifies vehicle installations. This core unit is paired with a 48-volt electric motor delivering nearly 13 kilowatts of power, or around 17.5 horsepower, mounted to the crankshaft output on the flywheel side and connected to the thermal engine via a clutch. This results in a system capable of operating solely on the combustion engine, solely on the electric motor, or in an integrated mode, the latter of which produces a maximum power output of about 42 horsepower. This output is managed by the thermal engine’s control unit but operates using Saim Industrial’s proprietary software. Developed with a team of electronic and digital control specialists, the program adds a fourth operating mode to the three previously mentioned. In this mode, the electric unit functions as an energy generation system that extends the operating range of onboard batteries, which can be supplied by Saim Industrial or sourced independently by customers, providing maximum flexibility for custom configurations.
Quiet by Nature
The new Saim Industrial hybrid unit is designed to meet the propulsion needs of medium-small agricultural and industrial machines, particularly those intended for use in emission- and noise-sensitive environments. The choice of an indirectly fueled diesel reflects this direction, with an inherently low noise profile. Kubota approached this by developing a patented, specialized pre-combustion chamber called “E-Tvcs,” operating with a multistage, electronically controlled common rail injection system. This results in the “Tvcr” system, which not only meets Stage V emission standards without needing EGR or exhaust gas after-treatment but also minimizes fuel consumption by about five to six percent compared to a traditional diesel engine with similar features and power.
