The
development of an ECU-integrated throttle body module for an
electronic fuel injection system for small motorcycles
Honda has a goal to reduce the total emissions of HC (hydro-carbon)
from new vehicles to approximately 1/3 and to further improve
the average fuel economy by approximately 30% (both from 1995)
by the year 2005. To realize the goal, we at Asaka R&D Center
considered that the small motorcycles used in many countries
in the world should be improved further for clean exhaust gas
and low fuel consumption. Accordingly, we have started development
of the PGM-FI system for small motorcycles with engines of 125cc
or smaller, including air-cooled engines.
To ensure clean exhaust gas and high fuel economy, the control
of combustion through an accurate fuel supply is a must. As
the conventional FI system (electronic fuel injection system)
applied to motorcycles is bulky and costly, its application
has been mostly in large motorcycles using multi-cylinder engines.
In the newly developed PGM-FI, in order to apply to small displacement
models, the obstacles have been eliminated by fully using Honda's
techniques to down-size components as well as making maximum
use of the FI techniques attained from the large motorcycles.
The compact PGM-FI offers new benefits such as the reduction
of released environmentally detrimental substances and the improvement
of driveablity, economy, etc.
