Development of “idling stop system” for small-size motorcycles
advanced system aimed to reduce fuel consumption and exhaust
emissions by means of an automatic engine stop, while the vehicle
is stopped due to a traffic signal, traffic jam, etc.
||Ever since its inception, Honda
has been conscious of environmental protection, as evidenced
by the challenges for application of 4-stroke engines
in Honda products. Shifting to 4-stroke engines for all
Honda motorcycles, including scooters, to reduce fuel
consumption while assuring clean exhaust gases, Honda
introduced the new-generation 4-stroke scooter in 1999.
While maintaining fundamental performance, this scooter
became the benchmark in terms of environmental protection
by reducing CO and HC emissions approximately 50% below
the 1998 Domestic Exhaust Emission Regulations. Also fuel
consumption was decreased by approximately 30% from the
previous models. All this was achieved by applying the
latest 4-stroke engine technologies. Additionally, the
newly developed “idling stop system” was employed to minimize
idling, further decreasing fuel consumption, exhaust emissions,
vibration, and noise. When compared to models without
the “idling stop system”, fuel economy improved by 5.1%.
In 2001, the “Crea Scoopy-i” was introduced as the first
50cc scooter equipped with a water-cooled 4-stroke engine,
which is lightweight and has an outer-rotor-type ACG starter.
Coupled with the use of the “idling stop system”, the
fuel economy improved by 5.5%* while reducing CO2 emissions
by 5.2%, CO by 8%, and HC by 2% without an additional
emission control system.
