Motorcycle markets are
undergoing a radical shift thanks to stricter global exhaust standards. Since
new specifications are difficult or impossible to fulfill with carburetor
engines, gasoline injection is becoming the standard. This is especially the
case in Asia, where motorised two-wheel vehicles are considered an
indispensable means of transportation for many.
As a result, there is a high
demand for marketable injection systems. With its M4L engine control unit,
Continental offers a highly efficient system for single-cylinder gasoline
engines with engine displacements between 50 and 250 ccm. The system stands out
for its extremely compact and robust design and sets new standards for
Now the technology company has further developed the
functions of the highly-integrated M4L module – which includes electronics that
take up less space than a pack of cigarettes – and made it Bluetooth capable:
The new version, M4L_BLE (Bluetooth Low Energy), brings connectivity to the
motorcycle alongside injection technology. Continental is presenting the
innovative solution at the EICMA in Milan, demonstrating the new possibilities
offered by its newly developed app functions, such as displaying average fuel
“With the M4L module, we are
adding a microprocessor to the motorcycle that can be used for more than just
engine management. We have used this opportunity to consistently develop the
system to offer better connectivity” says Torsten Bellon, head of Injection
Systems for the 2-Wheeler and Powersports area at Continental. “Thanks to this
additional functionality, our M4L system helps make motorcycles ready for future
exhaust standards and connectivity demands,” says Bellon.
The app prototype developed by
Continental allows drivers to display their average speed or average
consumption using a smartphone, for instance and to read out the error memory
of the on-board diagnostics system. In addition, the app can also offer a key
function to facilitate Keyless Start: Once they are sitting on the bike, riders
can be authenticated via their smartphone. All they need to do to start the
engine is press a button.
???????The M4L engine
management system is the latest generation of the “Air Module Engine Control
Unit” by Continental. This engine management system, which is specially
designed for lightweight motorcycles and scooters, integrates all key
components necessary to control the combustion engine into the throttle valve
housing – ranging from control electronics including microprocessor to the
actuator and sensors. This concept allows for an extremely compact design.
This miniaturisation is a key
advantage for two-wheeled vehicles with very limited installation space.
Another advantage: Eliminating exterior connections and cables to sensors and
actuators makes the system highly robust. Just like all engine control units by
Continental, the M4L system is a flexible solution that can be adapted to the
requirements of the market or manufacturer. It fulfills the newest exhaust
standards of Asian markets and already falls below the limit values of the Euro
5 exhaust standard planned for Europe in 2020.
