Japanese truck and automotive parts giants Hino and Denso team up for fuel-saving refrigeration unit
Hino says it has drawn on its hybrid drivetrain expertise to help create a world-first in truck refrigeration technology.
The collaboration is with fellow Japanese automotive manufacturer Denso Corporation, well-known in Australia for its air conditioning units.
The new Hino/Denso system uses energy generated by the hybrid diesel-electric drivetrain system — while both driving and braking — to operate the refrigerator’s compressor.
The new system will debut in Japan on the heavy duty Hino Profia, known in Australia as the 700 Series.
“Compared with conventional truck refrigeration systems which require an auxiliary engine or power from the main engine to run the compressor, the Hino/Denso system provides improved fuel economy, more consistent refrigeration performance and quieter running,” Hino says.
“The lack of an auxiliary engine delivers a weight reduction of approximately 150 kilograms, and simplifies truck refrigeration set-up and maintenance through the inclusion of fewer parts.”
The system can be connected to an external power source to maintain refrigeration when the truck engine is switched off for extended periods.
Hino trucks and buses use hybrid technology developed by the parent Toyota Group of Companies, to increase fuel economy and reduce emissions.
Hino Australia launched what it says was the world’s first hybrid production truck, the light-duty Hybrid 300 Series, in Australia in 2007.
The hybrid system was refined in 2011 as part of a full 300 Series redesign.
“Hino has a long-term commitment to producing hybrid vehicles that deliver driving performance, fuel economy and low emissions without any operational downside,” says Alex Stewart, Hino Australia Divisional Manager Product Strategy, Marketing and Customer Care.
“And the expertise that has come from this is now leading to even greater things.”
