To highlight performance, reliability and fuel consumption benefits, Allison Transmission will showcase its range of fully-automatic transmissions and hybrid propulsion systems for buses and coaches at this year’s UITP exhibition.
GENEVA, Switzerland - Allison Transmission will showcase the breadth of its transmission and hybrid technology for buses at the UITP Mobility & City Transport Exhibition on stand 4B525 (Palexpo; Geneva; May 26-30, 2013). Visitors to the exhibition can learn how the latest Allison Transmission technology can further improve driveline optimization and performance, while reducing fuel consumption and emissions.
The full range of Allison bus and coach transmissions will be on display, including the H 40/50 EP™ hybrid drive unit and Torqmatic® and 2000 Series transmissions, highlighting the wide scope of applications, which can benefit from Allison’s Continuous Power Technology™.
The advanced Allison 5th Generation control system integrates perfectly with the latest Euro 6 engines by incorporating new software and hardware that can enhance vehicle performance and efficiency. The all new Transmission Control Module uses a built-in inclinometer to further refine topography recognition, resulting in shift strategy and fuel saving improvements. The new chipset enables faster data processing and features enhanced End-of-Line programming and higher speed CAN bus compatibility (up to 500 Kbps). This new generation of electronic controls also provides two additional levels of acceleration rate management to allow for an even greater ability to improve fuel economy by moderating aggressive driving practices.
Fuel consumption and emissions reduced with hybrid systems
The H 40/50 EP™ hybrid drive unit will be displayed to familiarize visitors with the benefits and applications of the patented Allison dual-mode parallel hybrid system. By blending a traditional diesel internal combustion engine with dual electrical motors, the hybrid system offers a parallel architecture that reduces fuel consumption and CO2 emissions, while providing passengers with a smoother, quieter ride.
Notably, the Allison hybrid system has DC to DC converter capabilities and features HyValue™ strategy for better acceleration management to fit specific operating requirements.
“As a leader in the development of hybrid systems since the early 1990s, Allison Transmission has sold over 5000 H 40/50 EP™ hybrid systems to manufacturers worldwide. Much like our conventional transmissions, the Allison H40/50 EP™ is robust and reliable. It allows operators to manage their hybrid fleets as they would with traditional buses, but with advantages in performance and efficiency. In Europe, city buses equipped with the H 40/50 EP™ system have achieved up to 25 percent savings. In particularly severe urban routes, fuel consumption has been reduced even further,” explained Manlio Alvaro, Allison Transmission’s Europe, Middle East and Africa Marketing Manager.
