Iconos......... I have one

[Qiaozhi]

Hmmm... I wonder if anybody ever built a long range diesel engine locator? Now some large diesels run at less than 60 rpm, others over 10,000 rpm... Maybe a tunable diesel flame sensor hidden in a secret compartment?

My thoughts behind that question, about whether Geo's car is petrol or diesel, is that the diesel engine does not have a spark coil. So, is this why there was no beeping inside the car?

Yes, true! But consider the recent discussion of using valves to improve the performance of a LRL... Diesel engines do have valves...

Do you think that you are so clever?

Hi Geo, thanks a lot for your patiently and humbly answers.
the last question that brought me up here is the kind of engine fueling system.(of course in petrol fueling)
as you know guys, the petrol fueling are 2 kinds: one with carburetor and latest is Injector. FG80 gets signal only from Injector types I have tested it frequently in different cars.
another thing: in those injector types with less engine capacity (e.g. 1350 cc) it get from maximum 1 meter.
whereas in more capacities(e.g. 1850 cc or more) it gets at least from 5 meters and when you go closer it behaves crazily (continuous beep).
maybe it depends on Injector power. however it's related to Injector. what's the exact fact, comment and justification???

Hi,
not exact about remote engine localization...

Qiaozhi is right about no sparks in diesel engines... you have not to wonder too much about engine remote localization...I know that the AC-130 Spektre device of the Vietnam war found many of these diesel engine's noise from the sky... then they destroyed about 10,000 trucks... and big part of them were diesel equipped.

The fact that there aren't sparks in diesel engines don't mean that they cannot generate other kind of electrical noise ... think e.g. at backup system for batteries that is directly moved by engine itself... so when engine runs also other kind of electrical noise is generated e.g. at contacts of generator etc.

Of course, with LRL it could mean that no noise could be detected cause noise from sparks is much more easy to detect... due to the larger amount of RF involved (like in any strong spark gap emission)... but then if you near detector to the e.g. side of car where is engine... you'll detect "other" noise by LRL quite easy cause the smallest RF generated will travel easy to sensor... without the shielding effect of the inside of car.

Anyway... are just empiric results... and not so reliable; one must use the Carl's approach with antenna and RF generator to best find if it will respond to some particular frequency / modulation.

Kind regards,
Max

Hi,
found this on wikipedia: http://en.wikipedia.org/wiki/Magnetic_Anomaly_Detector

This is the detector I mean. M.A.D. used in AC-130 during the Vietnam war was both magnetic and electric based anomaly detector...

Wikipedia say...

"During the Vietnam War the original AC-130A Spectre gunships employed the "Pave Mace"/"Black Crow" magnetic anomaly detection system to detect truck ignition coils in vehicles hidden under heavy jungle canopies. The electric field of the truck coil, rather than its magnetic disturbance, was detected, giving another clue to the nature of the MAD sensor."

and you can belive that if you want.

That thing was just passive detection device... using a receiving array of sensors to locate on ground targets... then the 130 had also a primitive but working digital target locking system (kind of computer) to lock on targets the gunship fire from the armed side of plane.

10,000 trucks destroyed or maybe many more on the Ho Chi Minh Trail by night ! So to be MAD... it works and pretty good.

Could an LRL find a truck at night ? That's the problem!

Kind regards,
Max

Hi Michael.
Benzin, 1800cc ... injection system from Bosch
If detector don't beep at all models then it is a Opel Vectra 1.8l Benzin not DIESEL
Bye

Hi and thanks Geo. If so, then is awfully exquisite.
congradulations and with wish for the best and greatest founds for you. one 10 tones gold hoard as I know is possible to be found in Greece.

[roberts]

No wonder... oldest European nation and culure. So much things happened there. Once they had 50 states there - "polis" (city=state). I beleive, Ivconic told me, Geo is from Sparta. Spartan way of life! When i was young i enjoyed reading Greek history, Homerus,Eshil,Sofokles,Euripide...now i am to old.. i dont read any more!

[Delbert grady]

Goblet of Fire

Did you read Harry Potter yet. Hey brother Geo any chance of a balance sheet yet. You know Purchase price of Iconyou = $$$$$$: Less. Value of Gold found so far = $$$$$$ = Profit/loss= £££££

Hi Roberts.
hahahaha
You know good the Greek history.
But i am on from Sparti. I am and i leave on the center of Greece.
It is a small city with 40...50000 reople population.
Bye

Did you read Harry Potter yet. ...

Some people really dont have nothing to remember; like shamefull and poor past - history. In those cases they relying on fairy tales!
I didnt needed to read Harry Potter....i have all movies on DivX. Nice fairy tale for kids. You enjoyed it ....?
