The honda pgm motor cycle histories

honda pgm motor cycle histories

Honda began more than 20
years ago to develop a FI
system to continuously provide
The optimum air-fuel ratio
required by the engine using
electronic control techniques.
Since then, Honda has been
actively promote the
application of the FI to
motorcycles as a technique to
to achieve ecological
performance and a high level
handling.

In 1982, Honda launched the
first-in-the-world, fuel injected
CX500TURBO motorcycle,
who achieved both a better
acceleration
and better than the CB900F
fuel economy than the base
Model CX500. In 1998, the
eco sport
tourer model was VFR800FI
the market. This model, using
the PGM-FI and the new
developed three-way catalyst,
reaches 1 / 30 CO emission and
1 / 10 HC + NOx emissions
The EURO1, which is the
European emission standards
regulations adopted in 1999.
And now, the race machine
'RC211V' is
dominates the MotoGP races.

The "RC211V" uses the PGM
FI, which helps in allowing the
overwhelming power
the RC211V to be checked
efficient use of the rider.
Honda always keeps improving
the fuel injection system
the highest level of technical
competition.
The first engine equipped with
with an electronic fuel
Injection - CX500TURBO
In the late 1970s, Honda R & D
was filled with enthusiastic
to achieve "core
technologies that would
the development of new
technologies in the year 1980 ".
Through discussions about what
should be the core
technologies, "turbocharging"
was chosen, and CX500
was selected as the base
model. Honda defined the
goal of "turbo"
not only as an extra boost of
ability of a large
displacement, but a
increasing the specific power
of small-size
engine, and an increase in
thermal efficiency by reducing
The friction losses at
output. Simply put, it was
both an increase in reach
power and reduce
in energy loss. Most critical in
development were the
turbo charger and fuel
injection systems.

The
CX500TURBO ultimately made
The first stage of innovation
in the 1980s with his
acceleration
better than the "CB900F" and
fuel economy better than the
base model "CX500".
Computer controlled fuel
injection
One of the characteristics of the
CX500TURBO was
practical application of the
Computer controlled fuel
injection. Instead of
using the then-conventional
airflow meter, computer
controlled fuel injection
system calculated the
injection volume with the two
control charts, ie, one for the
boost area where the basic
injection volume was
determined by the engine
revolutions and the boost
pressure, and the other for
The area where the throttle
Basic injection volume was
determined by the engine
revolutions and throttle
opening. The actual injection
volume was adjusted by the
intake density compensation,
inlet pressure and / or
inlet air temperature,
Supplement for acceleration,
warm-up, starting the
compensation for the battery
voltage, etc.

Also
included in the computer
controlled fuel injection
system is a self-diagnosis
system activated
warning light and the backup
system for the engine to keep
performed when a fault
occurred in the system.
CX500TURBO
The racing machine of the 21st
century - RC211V
In the world of championship
motorcycle road racing, the
requirements of the machine
Pinnacle 500cc class
underwent a drastic reform,
and changed its name to
"MotoGP" in 2002. The
device regulations changed
a 2-stroke, 500cc engine
a 4-stroke, 990cc maximum
displacement, and the name
of the class was changed to
"MotoGP". The Honda RC211V
The machine was
developed to meet the new
regulations. Honda
developed a unique motorcycle
V-5 configuration.

After dominating the races in
the debut year 2002, the
RC211V will win in a
overwhelmingly in 2003.
RC211V
FI provide superior control
driving
MotoGP machine
completely closed or partially
open gas conditions
way more than the
Formula 1 race cars, for
example. Compared with the
Formula one car that use
fully open gas
often, the manageability
of power is more
critical than the maximum
power. Honda
developed and implemented new
techniques for beautiful offer
handling of the PGM-FI
used in the RC211V.
Twin Injector
Providing the multi-bend
levigation hole injectors
before and after the throttle
valve, and each one
provide the low load zone
(After gas) and high
load zone (gas)
both driving and
high power are
realized.
Variable fuel pressure control
The accurate control of fuel
and gas supply
manageability are achieved by
The ECU continuously
controlling the fuel pressure.

Predictive control of the remaining
fuel injected
When the throttle is opened
or closed (fully open, fully
closed, not when kept in a
partial opening), the "amount
of fuel stick "at the inlet
port walls and flows into the
combustion chamber during the
The following combustion
cycle is predicted and used
the control to ensure
most appropriate air-fuel ratio for
improve the ride quality
and fuel consumption.
List of Honda motorcycles
equipped with PGM-FI
The PGM-FI is one of the most important
technologies to achieve
goals of clean exhaust and
fuel. An inevitable
next goal is to extend the
the application of innovative
technique for models in various
categories that respond to a
larger number of users.

With the newly developed
compact PGM-FI, Honda
increases the application of the
large Touring models, the
Super Sport models, and
models aimed at
more people.
