FRANCE: Valeo and Ricardo to jointly develop 42 volt diesel technology

By just-auto.com editorial team | 1 October 2001

Valeo and Ricardo today announced that they have entered a technical and strategic partnership that combines Valeo's 42 Volt electrical energy and thermal management systems with Ricardo's diesel powertrain and vehicle engineering expertise in systems integration and control.

The two companies plan to jointly demonstrate technologies for a 42 Volt mild hybrid diesel vehicle that aims to reduce fuel consumption by up to 30 percent as well as beat future emissions legislation by 50 percent.

Under the terms of the agreement, the jointly developed mild hybrid vehicle, called i-MoGen (Intelligent Motor Generator) will integrate a range of Valeo's 42 Volt systems, including the company's integrated starter-alternator, its Heating Ventilation Air Conditioning (HVAC), intelligent engine cooling and other electrical systems.

A high output downsized 1.2 litre diesel engine will constitute the core of the powertrain system together with a supervisory controller to co-ordinate system operation, both developed by Ricardo.

Global customer demonstrations of i-MoGen are planned for 2002.

The Valeo and Ricardo systems will be installed on a "C" category standard production vehicle which is expected to be the practical demonstrator for future mass market powertrain technologies.

It is claimed that I-MoGen 'promises numerous benefits for vehicle manufacturers by addressing the key areas of fuel consumption, emission control and vehicle performance facilitated by 42 Volt technology.'

The i-MoGen vehicle demonstrator is expected to be complete by the end of this year.

i-MoGen has been set the following operational targets:

* Fuel economy. Less than 4 litres/100 km
* Exhaust emissions of 50 percent of current Euro IV levels
* Acceleration from 0 to 100 km in 10 seconds
* Production vehicle refinement and driveability

"Ricardo's track record in powertrain, vehicle systems integration and control combined with Valeo's established expertise in 42 Volt systems such as the integrated starter-alternator, HVAC and engine cooling systems will add significant systems integration experience for both companies. Moreover, this is a significant advancement for the automotive industry from which our customers and ultimately consumers will benefit," said Thierry Morin, Chairman of Valeo's Management Board.

"Valeo's committed research in 42 Volt technology, and its electrical energy management and thermal systems are an excellent fit with our powertrain systems experience," said, Neville Jackson, Director, Technology Product Group, Ricardo. "Our results so far have reiterated the importance of systems engineering, which is our joint expertise, especially when combining such intricate and advanced systems. Initial discussions with vehicle manufacturers to describe the vehicle concept have been met with enthusiasm."
