Re : engine management template

[peterlowrie]

A couple of questions...

1. Can anyone tell me where do I find premade or shared templates that I can import and customise.

2. In particular I'd like to find a virtual four cylinder four-stroke naturally aspirated petrol engine into which I can test various fuels and loads.

All of the work I do is done on Linux, but this shouldn't matter as I've been able to run VI's made on Windows on the Linux box and visa-versa.

TIA: Peter

Well that's a tall order as what you have not said is exactly what it is that you are attempting to discover form being able to modify these parameters and that has a massive influence on what is involved. I am assuming you aren't thinking of a complete engine simulation!!

There is no reason that LabVIEW won't do modeling but most people use a third party tool. I would put quite a bit of money on the fact that any complex models are probably being run on ABACUS, MATLAB, SIMULINK or other simulation packages rather than LabVIEW. (Well perhaps I should come clean and say I already have ).  The reason is that there is already a considerable amount of previous work available as wells as existing work in FORTRAN.

I think you need to narrow down the purpose of the model.

Hi Peter,

If you would like to model a complex engine in LabVIEW, you can use the toolkit called Simulation Module.  This module can create complex models.  If you can provide some more information regarding your model requirements, that would be great.  I hope this helps!

The final and exact outcome I'm looking for is still a secret, so if I told you I'd have to kill you. What I can say however is; In the process of preparing my alternative fuels paper I have researched various fuel mixtures on engines under load. It turns out that some fuels will make an engine run but will fail under load. Hydrogen is a prime example. Another take on the work involves addition of oxidisers (such as nitrous oxide, oxygen or water) to running engines under various load conditions.

If Berthots (theorems) Laws are to be taken seriously there exists in many fuels a bell curve of potential energy but that only the starting and ending positions apply to calculating overall available energy. My Australian colaborator and I are reviewing the equations relating to combustion plasmas and whether atomic ionising energies account for (or not) the bell curve mentioned above. If other mechanical processes used in fuel production are eliminated then Berthots theorems will need modifying.

Sorry about being so cryptic. A lot is lost in paraphrasing in a few words the entirety of the research undertaken so-far. I wonder if you'd mind sharing your VI with us.

Oops, typo...Sorry.

Berthlot should be Berthelot

I find my self in a similar position to yourself; in that the research being carried out is protected from public release (even the thesis documents) for 5 years. The objective of the model is slightly further down the chain and concerned more with what is going on as a result of the combustion, rather than the combustion process it's self.
