            <div class="section-description padding-bottom">With any conventional gasoline fuel system, when refueling, <strong>fuel vapors are generated inside the tank</strong>. These fuel vapors are guided through a venting system to a charcoal
              canister where it is absorbed.<br>The charcoal is purged each time the combustion engine is in well-defined conditions.&nbsp;&nbsp;<br><br>When the vehicle is <strong>parked for several days</strong>, the canister will be loaded each
              time the internal tank temperature increases due to the heat variations during the day and would be only slightly purged when the temperature decreases.&nbsp;<br>&nbsp;<br>Consecutive diurnal cycles progressively load the canister which
              can <strong>only be purged when a new drive cycle start</strong>.&nbsp;<br>&nbsp;<br><strong><u>Case of hybrid vehicles</u></strong><br><br>Plug-in hybrid vehicles combines an Internal Combustion Engine (ICE) with an electrical drive
              train.&nbsp;<br>The <strong>ICE can be switched off for an extended period of time</strong>, rendering it <strong>unable to burn the fuel vapor which continue to accumulate in the tank</strong>.&nbsp;<br>&nbsp;<br>After a few days, the
              canister is no longer able to absorb the fuel vapors and an electronically controlled tank isolation valve prevents their release into the atmosphere, in accordance with environmental regulations.<br>&nbsp;<br>On a sealed fuel system,
              vapor generation creates <strong>internal tank pressure</strong> leading to <strong>significant deformation of the tank shell</strong>.&nbsp;<br>&nbsp;<br>Therefore, the <strong>tank shell must be reinforced</strong> with external and
              internal components to <strong>minimize the tank deformations</strong>.&nbsp;<br>&nbsp;<br>To avoid or at least limit the tank pressurization or the canister load, <strong>alternatives for managing fuel vapor</strong> may be of
              interest.<br></div>

ALTERNATIVE FUEL VAPOR MANAGEMENT

We have developed three solutions that aim to eliminate the negative effects of
fuel vapor generation in tanks.
The power supply of hybrid vehicles can take over from the combustion engine for
a long period of time, making it unable to burn the fuel vapors that continue to
build up in the tank, causing high pressure that can lead to deformation.


What do you think about it?


HERE IS THE PROJECT


YOUR ADVICE


ISSUE

With any conventional gasoline fuel system, when refueling, fuel vapors are
generated inside the tank. These fuel vapors are guided through a venting system
to a charcoal canister where it is absorbed.
The charcoal is purged each time the combustion engine is in well-defined
conditions.  

When the vehicle is parked for several days, the canister will be loaded each
time the internal tank temperature increases due to the heat variations during
the day and would be only slightly purged when the temperature decreases. 
 
Consecutive diurnal cycles progressively load the canister which can only be
purged when a new drive cycle start. 
 
Case of hybrid vehicles

Plug-in hybrid vehicles combines an Internal Combustion Engine (ICE) with an
electrical drive train. 
The ICE can be switched off for an extended period of time, rendering it unable
to burn the fuel vapor which continue to accumulate in the tank. 
 
After a few days, the canister is no longer able to absorb the fuel vapors and
an electronically controlled tank isolation valve prevents their release into
the atmosphere, in accordance with environmental regulations.
 
On a sealed fuel system, vapor generation creates internal tank pressure leading
to significant deformation of the tank shell. 
 
Therefore, the tank shell must be reinforced with external and internal
components to minimize the tank deformations. 
 
To avoid or at least limit the tank pressurization or the canister load,
alternatives for managing fuel vapor may be of interest.

SOLUTION

Solution # 1 - Thermoelectric cooler 
The first solution is to use a thermoelectric cooler (Peltier cell) to cool down
and to condensate (at least locally) the fuel vapor inside the vapor dome. 
 
Solution # 2 - Bladder
The second solution is to use a bladder (=a kind of bag) connected to the
atmosphere to compensate the pressure variation inside the tank. 
When the pressure inside the tank increases, the volume of the bladder reduces,
so the pressure inside the tank does not change. 
When the pressure inside the tank decreases, the volume of the bladder
increases.

Solution # 3 – Separation device


The third solution is to use a membrane to separate the hydrocarbons from the
mixture of hydrocarbon (HC) vapor and Air coming from the canister. 
 
The process works in different steps:

 1. The canister is loaded each time the internal tank temperature increases due
    to the heat variations. 
 2. At a well-defined moment, the purge pump is activated and the canister is
    purged. The HC/Air mixture coming from the canister is sent to the
    separation device. 
 3. A specific device separates the HC from the previous mixture.
