We want to actively

to introduce environmental

vehicle technology

used by several people.

In doing so, we want

help improve

Global Environment

even a little. This is

base position for Honda

Environmental Technology

including fuel consumption

and cleaner exhaust gas.

Asaka R & D Center has developed

PGM-FI technology developed

for short trips

engines such as 125cc and

newly developed

electronically controlled fuel

injection devices, PGM-

FI, suitable for use in 4-stroke,

50cc scooters, the current

marketed by Honda as "Net

4 ".

World's First as a mass

produced 4-stroke, 50cc

Motor

Electronic control

fuel injection system, PGM-FI

with fuel

consumption and net

flue gas is

developed for mass-produced

50cc 4-stroke engines to

first time in the world.

With this technology,

further reduction of fuel

consumption and net

flue gas will be promoted

for the 50cc engine class

including the largest sales

domestic market.

Technology Features

The most remarkable feature

CAG is the integration of

Starter control and PGM-FI

the shield through

installation of processors that are higher than

32bits. In addition, new

technology has been developed

to mount a 50cc

scooters, including the new

injectors, ultra-small fuel

circuit pump and a new system

to revive. In addition,

number of copies

15-8 is reduced as

compared with PGM-FI

designed to model a large

through the efforts

integration of various functional

section, detection of consolidation

functions and new design

The main parts including fuel

pump. Low cost, compact

electronics and light

controlled fuel injection

system has been achieved.

Built ECU

It functions

consolidation for low

costs through the adoption of high

CPU speed and 32bit

PGM-FI integrate control

ECU with ACG starter

control ECU. In comparison

with conventional 16bit

Processor speed, the treatment was

increased and 3.5times

doubled the memory capacity

which allows the integration

FI control and ACG

control starter in the shield.

Compared with the ECU to

for conventional 50cc

scooter, reduced size

21%.

New ECU 32bit 32bit processor performance

Compact fuel pump

To keep the floor flat to

50cc scooters, ultra-compact fuel

developed, which can

The new injector

The number of gasoline

required for combustion in

small-displacement engine

very small as 50cc

and small amounts

gasoline must be burned as

efficiently as possible. There is

It is therefore necessary to fuel

injectors one minute

Idle air control valve

For small motorbikes, such as

developed for 50cc scooters,
