 
Cold
Start-Up System |
A
Cold Engine Start-Up System must be installed. Alcohol
and gasoline present different physical characteristics
and, when temperature is below 15ºC and the tank
filled with alcohol, engine start-up is hard.
In order to overcome the cold-starting issues, a 15-percent addition
of gasoline is recommended each time you fill the tank. This
may offset the problem, but will not guarantee immediate engine
start-up at very low temperatures.
ALCOFLEX´s program facilitates the use of cold start system,
but we stress that there may be situations in which a second
start attempt must follow.

Fuel
pumps |
This
is a particularly delicate issue in fuel conversion (using
ALCOFLEX or any other equipment). After a while, the
fuel pump may need to be replaced according to the car
brand, model, manufacturing year and corrosion tolerance
for adulterated fuels. It is important to mention that
the gasoline currently available in the brazilian market
has an estimate 25 percent alcohol addition, which lead
us to conclude that the fuel pumps on the market already
have a protection against alcohol corrosion.
Another important alcohol characteristic is that, once it
presents no solvent in its composition, all those impurities
deposited in the bottom of the tank resulting from gasoline
use may detach and cause filters and pre-filters to be stuck,
blocking the fuel flow and therefore harming the pump. See
details in http://www.dana.com.br
A pump pressure test is adviseable both during installation
and after 1,000 km, when it should be repeated.
Warning: sudden increase in fuel consumption and engine
cranking without starting may indicate problems with pumps. |

Injection
Nozzles |
| No
need for replacement. There is no relation between alcohol
use and a reduction in estimated lifespan. |

Engine |
No
changes need to be made in the original engine or injection
module parameters. |

Compression
Ratio |
ALCOFLEX,
as well as any other electronic conversion system or
device, does not compensate the compression ratio. See
more details in“MYTHS
& TRUTHS”.
What in truth happens after installing ALCOFLEX is that no
increase in engine power is gained. The compression ratio remains
unchanged, and therefore the energetic and calorific potential
of alcohol is not fully used. On the other hand, there are
no significant losses in engine power and, in certain cases,
no losses whatsoever. Engine power is directly proportional
to compression ratio – in other words, the higher the
rate, the better the performance of your engine. |

Filters |
An
antecipated replacement in gas filters is highly recommended,
as mentioned above. Alcohol then provides a better engine
cooling and facilitates the removal of impurities from
the tank and the feeding system. Ideally, a replacement
should be done after 1,000 km. Oil
filters – There is no need for an immediate replacement.
It can be done after the next oil change. It is important to
mention that alcohol eliminates any possibility of oil contamination
by solvents, then increasing lubrication effectiveness and
cooling.

Fuel |
Be
extra careful while filling your tank. Your car will
surely not run well and have a very poor performance
in case you use by any chance adulterated alcohool. Seek
only reliable fuels. |

General
Vehicle and Engine Conditions |
In order
to instal ALCOFLEX, your engine and its parts must be in
perfect working conditions. Sensors, among other mechanical
and electrical parts, must be checked for a successful
installation. |
