Bosch brings electronic fuel system, connectivity to Asian motorbikes

October 31, 2014 // By Christoph Hammerschmidt
With an electronically controlled fuel injection system for motorcycles, supplier Bosch is offering a more efficient alternative to the predominant carburettor systems in this class of vehicles. The company has developed solutions for affordable two-wheelers in Asia. On top of the engine control solutions, Bosch also offers connectivity options to motorbikes. The offerings focus on the specific demand of Asian markets.

In Asia, motorcycles with engine displacement under 250 cubic centimetres are a means of mass transportation and at the same time a mass market. Currently, many machines are still fitted with carburetors. Here Bosch believes its technology offers a decisive advantage: compared with the mechanically controlled carburetor, and depending on situation, the electronically controlled fuel-injection system can reduce fuel consumption by up to 16 percent. This also significantly reduces emissions and use of resources.

For the Asian markets, Bosch has developed an affordable engine management system. At the core of the new Bosch engine management system is the control unit, a small computer that analyses data from the powertrain, from the ignition to the amount of fuel. The system interplays with safety systems such as the MSC motorcycle stability control system, which ensures safe braking and acceleration even when leaning into bends.

In addition Bosch offers a Bluetooth interface and a connectivity control unit, which enables motorcyclists to connect their vehicles to external devices such as a smartphone. Apps will then enable new functions. Bosch has already unveiled three possible applications: an enhanced on-board computer, software for remote diagnostics, and an app-controlled immobilizer. The enhanced on-board computer can display data on fuel consumption and average speed, for instance. This makes it possible for motorcyclists to analyse their trips after they have returned home. If a diagnostic app has been installed, the rider's smartphone can serve as a readout device. It displays error codes, for instance, thus making repairs easier.

Connectivity is also gaining importance in the Indian market, as the example of the smartphone-based immobilizer shows: fuel injection and thus also the engine can only be activated by means of the rider’s own smartphone. Two-wheelers can thus be personalized, which provides additional protection against theft. Going beyond connectivity with smartphones, an on-board computer that can be personalized and connected both to the two-wheeler’s systems and the internet is a promising
