SKF Stop-start system for motorcycles reduces CO2 and fuel consumption
SKF has developed an innovative stop-start system for motorcycles and scooters. Called SKF StopGo, this automatic plug-and-play system reduces CO2 emissions and improves fuel economy by an estimated 6-8%, depending on driving conditions.
“Automatic stop-start has been seen mainly in the car segment until now. Although a relatively new solution it is becoming increasingly common across model ranges, because of the fuel saving advantages it delivers. With the launch of the SKF StopGo solution, we are now bringing this technology to the two wheeler segment,” says Franco Ferro, SKF Automotive Division, Powertrain & Electrical and Two Wheeler Business Unit Director. He adds, “This advance reaffirms our commitment to providing sustainable solutions and helping our customers and end-users reduce their carbon footprints.”
The SKF StopGo design concept allows it to be customised as a ready-to-fit unit which can be assembled quite easily by both OEMs and as a retrofit for a wide range of motorcycles and scooters already on the road. The system can be applied to a wide variety of vehicles, independent of engine size.
When the vehicle has stopped, for example at traffic lights, the SKF StopGo automatically detects the lack of motion and after a predetermined, but programmable, interval shuts off the engine. The system immediately restarts the engine as soon as the throttle is opened.
SKF StopGo is a three-in-one integrated sensor-bearing system that performs bearing, speed sensing and stop-start functions. The unit fits into the hub of the front wheel, in the same way as a standard bearing, and is connected by a standard connector to a mating unit attached to the engine electronics.
As well as sensing the speed for the stop-start function, SKF StopGo provides normal speed data for digital tachometers, which are becoming more preferred than analogue systems in new motorcycles and scooters. In addition, this new single-unit solution offers advantages of weight saving of up to 60% compared with conventional front wheel bearing and speed sensing mechanisms.
