The brand new Mild Hybrid powertrain presented at Agritechnica
Capitalising on over 25 years of experience in the development of integrated systems for material handling applications with electric drive
Once again, Agritechnica is the ideal showcase for Carraro Group to show off notable innovations that define unprecedented standards in the field of agricultural mechanisation.
One example is the heart of the Carraro stand, where a Mild Hybrid powertrain for specialised tractors is being presented for the first time - a product solution that brings together a number of new ideas.
The first is the new Carraro 3E22 endothermic engine (3 cylinders, 2227 cm3, 55kW). Developed for specialised agricultural applications, this engine - also available in a version that can be used on worksite machines - was designed to comply with the emission limits of T3B, Stage V, China IV and Bharat IV.
Thanks to the integration between the internal combustion engine and an electric motor - 48V from 20kW, this unprecedented Powertrain (transmission combined with a front axle with IFAS suspensions) offers the agricultural world the ideal solution for guaranteeing the same advantages as a 100 hp engine whilst optimising fuel consumption.
This is made possible by the reduced size of the endothermic engine and the smart management of the electrical boost function that can sustain and optimise the diesel engine overload (e.g. during transportation and work).
Thanks precisely to the downsized internal combustion engine - just 55 kW - this solution also avoids the need to install the SCR catalytic converter to meet the European STAGE V standards; this means undoubted advantages for the specialised tractor in terms of overall dimensions and cost.
The structure of this new powertrain confirms the outstanding skills of Carraro Group, including a knowledge of electrification built up in over 25 years in the material handling sector, with particular reference to electric drive transmission systems.
