wire diagram

Hooray, we have finnaly put each components onto the wood board. when we took them out off a vehicle, we had to cut their connction wires to make job easy. as a result, now we have to re-wire them to make them work. Thanks to Tony, he has got all the wire diagrams which we need. and aslo we both agreed to use anti-freeze to simulate the fuel running in the fuel system which will avoid any cathing a fire accident. but i am still a little bit worried about that if we can successfully  get the fuel to the injectors and have desired spay patterns.

catch up

lucky, we have the chance to look at a EFI circuit board which is very professionally desgined. it really gives us a idea how to improve our project. After talking to our supervisor, we are happy to design our own EFI circuit as a extra part of our project which we think that will greatly help the purpose of education. if we can come up with a very nice finished project, we will have the chance to sell it to some educational institute. as a memeber of our team, Tiitii had a big surgery which is required to take this semester off by the doctor. so now only Tony and i have to fnish the project. we know it will be a chanllenge, but even though we will face it.

problems with our project

in our TC project, we have solved the issue which is how to control the distributor. we came up with the idear to use a DC speed motor to simulate the engine revolution. however, how to simulator the engine vacuum will be a real big problem. i did some researches which like using a Ford vucuum pump used in diesel engine. and aslo we can use a hand-operated vacuum pump in which we can exactly control the vacuum produced in the petrol engine. the other problem is that Tony thinks we can use a hammer to simulate the engine knock event. but as far as i know, the engine knock sensor actually only works in a specific frequency. so it won't pick up the unrelated noise. and in fact i saw some one failed to simulate the engine knock event by hit the engine with a hammer.
