In operation since 2006, Effenco’s multidisciplinary team has developed a hybrid system for heavy-duty trucks equipped with hydraulic auxiliary systems, such as refuse and cement trucks. Designed with high-quality components, the hybrid system that was developed generates 20 per cent savings in fuel, triples brake lifecycles and reduces greenhouse gas emissions by 19 tonnes per truck per year. Effenco’s hybrid HEAD™ system is installed alongside the vehicle’s propulsion system in a parallel configuration, and saves up to $10,000 per year in operating costs.

Effenco Development is a Montreal-based company that develops and markets technology solutions for improving the energy efficiency of heavy vehicles and reducing greenhouse gas emissions. Effenco’s aim is to become a model in green technology for the transportation industry.

Says Effenco President David Arsenault, “In a context of rising fuel prices, the idea of saving 20 per cent annually on total fuel costs becomes very interesting for fleet operators. Additionally, being recognized as a leader in durable development isn’t too bad either. It’s a win-win situation.”

A patent application has been filed for the unique architecture of Effenco’s hybrid system. This system was designed to be installed on both new vehicles and vehicles already in service (retrofit) and includes an interactive dashboard that displays ecodriving tips. In addition, using its unique service that characterizes vehicle fleets, the Effenco team estimates the potential savings in operating costs prior to installing the systems to pinpoint routes where performance is optimal. This informs operators of the real potential of the hybrid system. Once the system has been installed, an interactive dashboard providing ecodriving tips helps maximize the system’s performance, thus reducing the time to achieve profitability.

Because it doesn’t affect how the vehicle is driven, operators can make the switch very easily. The system recovers the energy generated during braking through a hydraulic pump connected to the drive shaft via a transfer gearbox. The pump compresses the oil in a hydraulic accumulator that stores energy in the form of a pressurized fluid. The energy is then transmitted to the truck’s auxiliary hydraulic equipment (compactor, automated arm or concrete bucket, for example). This limits the solicitation of the internal combustion engine, generating fuel savings.
