A major trend has been the gradual emergence of eco-friendly vehicles, which have systems that automatically switch off vehicle engines during idling, for instance at red traffic lights. According to various research studies, vehicles are at a standstill for one-third of the time while in urban areas. Stop-start systems could help make cities quieter, boost fuel efficiency and reduce exhaust pipe emissions.

Developing systems takes a lot of engineering effort simply to obtain a stop-start function. “Setting aside the additional cost,” said Mike Dowsett, senior manager for micro-hybrid systems at Controlled Power Technologies, “the critical issue for automotive engineers developing stop-start is product refinement and how much confidence the driver has in the system..."

Dr Gerhard Wagner, member of the board of management, ZF Group and responsible for the group’s car driveline technology division, told us: “The savings potential of a start-stop system is solely due to the fact that the combustion engine is switched off once the vehicle is stopped. If even greater savings effects are to be generated, then more complex systems are required; systems that enable recuperation or shifting of the combustion engine’s operating point.”

This report looks at starter motors, alternators and new technologies (such as stop-start) affecting these components.

Following Chapter 1's Introduction, Chapter 2 The Market starts by reviewing recent activity from the major OE and afermarket suppliers including Prestolite, Bosch, Denso, Lucas Electrical, Mitsubishi Electric, Motorcar Parts of America Inc, Remy International and Valeo.

The chapter provides 2008 global market shares for OE alternator and starter motor manufacturing for cars and heavy duty applications.

Also provided is just-auto's latest market volume and value estimates. From 2006 to 2016, we provide market values of OE alternators and starter motors for passenger cars produced in North America, Western Europe, Eastern Europe, Japan and China, plus market volumes for alternators and starter motors sold in the aftermarket for each major European country (data provided for both cars and commercial vehicles).

Given the sheer volatility of the global economy at present, we have set out an ‘expected’, ‘best case’ and ‘worst case’ scenario for all our forecast estimates.

Chapter 3 Technical review
Stefan Asenkerschbaumer, president of Bosch’s starter motors and generators division, believes that the start-stop market will grow rapidly in the next five years. He said: “In 2008, roughly 5% of all vehicles in Europe were equipped with a start-stop system. By 2012, we estimate this technology will be [in] every second newly registered vehicle.”

This chapter provides coverage of the latest stop-start technology launches. Included is our interview with Controlled Power Technologies, exclusive comments from ZF, plus an interview with Antonov.
