Creating a PANTONE multi fuel car on gasoline

Unread Messageby manoria68 » 20/10/08, 13:58

The purpose of my editing is to fuel a reactor with Pantone and EFI to use different fuels.

The ideal would be to cut the injection of the car and use as fuel in multi Pantone

Here is my reactor

Tube 12 / 14 rod heart 10mm and elbows brass 3 / 8 smaller

The tube that runs around is my boiler.
It can not be used

For the recovery of the signal, it is copied to the same as the original injection. (Function used to map)

Image

I also have the ability to send a PWM signal, thus sending a Sygnal in the injectors variable duty Hours of Operation: (not used) in french: open injectors to 0 100% but this function is not used.


The signal thus fueling a secondary injection rail placed in the cockpit.

Image

The latter feeds the reactor.

It is supplied by a tank mounted separately from the car

Image

of course, you can go from one energy to another by cutting the car's fuel pump or pantone
Image

Here is the reactor with some descriptions:

And connection to the motor:

These tests do not work as the car stopped and idling

After some advice, I changed to this:

I create a plastic adaptation between the throttle and the collector

His move aligns closer to the venturi cone throttle and not to repeat the EV idle



The adapter:

Image



All mounted

We can see the fabric filter between the hose and the copper tube
I did not put the injector to enrich for Ethanol currently.
Image



View from inside:

Image



So is mounting with his beautiful and well aspire to all plans. Just a little less when the throttle is opened fully.



Trials with injection origin disabled car and Pantone enabled:



At trial, the car is multi fuel to 30 Km / H (after pre heating) to the beyond, I must accelerate more and the engine takes over. I think depression is no longer adequate to the reactor, I know.



Injection tests with original car pantone activated and deactivated:

Leaving plugged injectors 2 the Pantone injection, I increase the richness of the mixture. Its means ...


After several minutes, the computer recalculates the wealth of the poorest manner mixture and the engine returns correctly.


Its means that rotates E85 to 50% and 50% for rapeseed oil and water at the moment.

We now see at the consomation will give her and also with different mixtures

Test 21 2008 October

Test performed with activated drive injection
Pantone activated and 1 injector on trendy 4

Or the conditions of a doping

The tank contains Pantone 40 40%% oil and water, 10% of rape, SP95 ect ...)

On 108Km, I consumed 1L mixture of Pantone tank and level of consumption, a decrease of 23%
Considering the price of a half liter of oil consumed his back the cost of the trip to 17% less


Tests on the same highway

Question for NLC

Is it possible with your editing impoverish the mixture?

http://chaenel.free.fr/cmsimple/?Electr ... thanol_E85

It would be interesting for my editing

She would order the original injection ramp -50% to + 20%
To make trial without the calculator will impoverish the calculation of mixture

Example: start ethanol + 20%
once the hot reactor, impoverish 50% of the mixture injected by the injection original engine and injectors connect 2 my injection rail Pantone

This is how my camera (and others too):

Image

So impoverish it is not theoretically possible, since we do not know in advance what will be the width of the injector pulse, so we can not know when to shut off the nozzle.

Would there be means to do to overcome the problem is to make the measurements injector pulse, but pass on impoverishment of the next pulse.

This is easy to do but I do not know if it would work correctly, since the shares of the injector pulse width arrive at the injector with 1 4 delay time cycle, so 2 towers engines (multipoint injection on sequential)

I guess on a single-injection ca would not be too serious since an impulse dedicated to a cyclinder would simply be shifted only following cyclinder. On a sequential multipoint suddenly I do not know what it could give.

Quite ok on what you just said, but what you have the opportunity to try on your installation?

Otherwise, I can also play on the pressure in the fuel rail
this seems less uncertain me

But if I install this kit on my car, his simplifierais me anyway mechanics ...

Yes ! But also how is regulated the pressure in the original injection rail? The pump pushes like a barbarian and the end of the ramp is a calibrated valve which opens to the desired pressure and let the fuel back into the tank?

A solution to change the pressure would be a pressure sensor at the ramp and a small electronics that change the voltage of the fuel pump PWM.

In this case the valve would no longer his role, there would be more fuel flow. Can be bad for the pump of the sudden?
