Kubota presented a prototype micro-hybrid system to help OEMs downsize while maintaining overall machine productivity.
Designed to support the existing engine, the new system enables a three-cylinder unit to achieve similar performance levels to a conventional four-cylinder, while avoiding the need for installing the larger, heavier version.
An additional electric power boost of up to 10kW (13.4hp) immediate torque is available, and its battery pack is recharged when not initiated.
In addition to the extra power, the system allows for reduced fuel consumption and lower operational costs and the engine management control means it is compatible with many of the diesel, gasoline, LPG and natural gas engines across the power ranges offered by Kubota.
“Utilizing and benefiting from an independent driveline, the micro-hybrid system maintains accessibility to the existing power take off positions of a conventional engine,” said Daniel Grant, marketing manager of Kubota Business Unit Engine Europe. “This can be particularly appealing to both existing applications and more compactly designed applications in the future.
“We believe in providing a proven power source solution for our customer needs and that there will not be just one power source in the future.
“It is clear that the trend toward downsizing is increasing, as the need for greater fuel efficiency, durability and total cost of ownership becomes the market focus.
“A micro-hybrid system that provides power assistance instantaneously is a genuine technological innovation that can make a real difference to our customer’s current and future needs.”
