Zytek EGS to be supplied to Formula Nippon
Zytek is to supply its Electrically-operated Gearshift System (EGS) to Japan’s major single seater racing series, Formula Nippon. All the cars racing in the championship will be fitted with the EGS, Zytek supplying twenty five systems in total for next season.

The EGS has already demonstrated its reliability after successfully completing two seasons fitted on all the cars in the A1GP series. The lightweight, high performance system has also been used on Zytek’s own LMP1 and LMP2 sportscars in 2004-2007 in endurance racing worldwide, as well as the renowned Le Mans 24 hour race. This season the system has been used in the three Acura teams racing in the American Le Mans Series.

The Zytek EGS is lighter and more straightforward than alternative pneumatic or hydraulic systems and the all-electric operation offers engine downshift protection, reliability, simple integration and improved gearbox life. The EGS can produce individual gearshifts in less than 40ms and up to five downshifts in less than one second.

The precise movement of the electric actuators also means that there is very little wear on the gear selector mechanism and dog rings, extending gearbox life and improving reliability and shifting accuracy. The fully electric approach removes the need for a separate hydraulic or pneumatic system, reducing vehicle mass and complexity. Once fitted, the system is essentially maintenance-free and there is no potential for leakage of air or hydraulic fluid.

The EGS requires extremely precise control and state-of-the art energy management. Zytek has made use of its extensive background in control electronics and software and the electromechanical design expertise of its electric vehicles division to engineer a system which can operate reliably in the most demanding race conditions without excessive power consumption. The EGS control unit includes built-in energy storage, which accumulates electrical energy from the vehicle alternator between gearshifts and delivers high power extremely rapidly for a super fast shifting action. All system components together with the control and calibration software have been developed in-house by Zytek.

Following the conclusion of the new deal with Formula Nippon Zytek’s Motorsport Products Applications Manager, Phil Lord said, “Zytek had an involvement with Formula Nippon for many years until 2005. We are very pleased to be able to renew our involvement in this professional championship with a new Gearshift Control system to be made available to all entrants. Formula Nippon creates international interest for drivers to sharpen their competitive skills and Zytek are proud to be involved again, and are grateful for the exposure Formula Nippon will present to other potential markets.”
