Kill switch for diesels

[OTEP]

Intended for LC80 with 1HD-T engine.

Is there anyway to rig a kill switch with delayed shut off for this rig? Diagrams, tips and other words of wisdom would certainly be appreciated. Thanks!

You mean someting like this?

Lots of others around but this one is different as it matches your driving to the timer

Actually, I'm looking into one to function as anti-theft device.

So when thief hotwires the vehicle, it will start. Only to stall a block or two from the scene.

Seems like thieves are less likely to rehotwire a car that stops in transit.

 

[roscoFJ73]

Maybe a well hidden fuel cut solenoid that can only use the fuel in the lines would do the same job.

Only problem with it is it still gives the thief time to get the vehicle out of the immediate area where it can towed or stripped.

I can see your point of a thief not wanting to hotwire a vehicle twice but this is a landcruiser and the parts are valueable.
Much better to look at options that totally immobilise it.

Landcruiser's are second only to Hyundai Excels for theft in west aust and have the lowest recovery rate

The injection pump of 1HD-T engine have any positive wire . ? or is pure mechanical . ?

In the 1KZ-T engine the inyection pump have a positive wire to proper injection pump function .. if you cut it the engine dosen't run.

absolute same thing with the HD-T

This is what I want to do as well.
Have a hidden fuel pump switch.
That way they can only drive a few blocks until they run out of fuel.

I highly doubt the thief will troubleshoot the problem.
He would have to find the swtich then assume it's a fuel pump cut off switch. Then pop the hood and reprime the diesel. Any thief I could imagine would crank on it for a bit and then run away. I doubt they are going to troubleshoot a stolen truck.

Please let me know what you find out.
As I will probably do the same.

Cheers,
Nick

i think sometime around the 90's some stinger car alarms had a feature similar to what you guys are talking about ... they were removed from the US market due to the liability involved in such a feature ....

if you think about it this could get someone killed .... what if the thug is already on the freeway doing 140kph and the engine shuts off ... in the states this would result as ivoluntary manslaughter and the owner of the vehicle would be held responsible

I don't necesarily agree with the american judicial point of view and i guess things are different in the Philipines (civil law right?) ... but it is just something to consider

the intelligent turbo timer looks nice

I know from experience a 3B will only go about 1/2mile before running out of fuel. A 1HD-T would not even go that far (especially at 140kph). So unless your parked on the onramp to the freeway is this really a problem?

Nick,


Otep had mentioned something about a delay in the shut off .... I guess a thirty second delay wouldn't be a big deal but say a 5 minute delay could get someone in trouble ....

maybe Otep's hospital is on a busy street .... what happens if his rig gets stolen and the thief gets it to the street and looses brake pressure and power steering after the engine shuts off and runs over someone or falls off a cliff

I know this is VERY circumstantial but it could happen and in some countries the chain of events could put the blame on whoever installed such a system

this is why this feature WAS available in some car alarms and has been removed .... all I'm saying is it is worth considering

regards,

By delay, I meant in seconds. Just enough to distance the vehicle from the victims in case of a carjacking. I'm thinking about a hundred meters.

The 1HD-T isn't that blindingly fast. I doubt if he'd hit breakneck speeds.

There are no cliffs here and it's pretty congested you'd prolly just have a fender bender in the process.

I was just thinking out loud regarding the idea. Your inputs are certainly appreciated.

The concept on those " secity " system are, you need specific amount of time, to runout of the attack secene for example .. if the system cut the diesel a few meters after .. you are in the same place with the attacker.

would love to hear a lawyer opine on this one.... I've gotta guess that even in the usa, it would be tough to create a situation in which a vehicle owner could be held liable for an accident that happened after his/her vehicle is stolen. Please, someone, please tell me that I'm right!

Maybe if you put a small sticker on the window glass with a "By intruding into this vehicle without owner's permission, entrant expressly waives all future claims against owner" or some stupidity of that sort.... it works for software manufacturers, right?

We have been installing hidden toggle switches for years as a starter interrupt.
What you are thinking of (a dead man's switch) is common on snomobiles in case the rider falls off.
The problem with shutting the engine down is liability.
First of all, you don't want to have the switch for fuel anywhere where it can be accidently toggled. Hypothetically, if the engine stalled and the passenger took over to steer, it would be very difficult from that angle because you loose the power steering and the power brakes.
I never recommend ever going into the fuel or ignition system. There are too many unknowns and too many situations that are not foreseen.
Some lawyer would have a field day with such a situation with a vehicle wired accordingly.

Nice thought, but it has been tried on the old carb vehicles. Car stopped in the middle of intersection and family was hurt. Happened more than once.

Thanks for the thoughts

I don't know if liability will be an issue. Most GSM-based anti-theft systems sold here enable you to send an SMS message and instantly kill the engine should the rig ever get stolen.

But GSM-based systems are expensive.

A GSM-based system is standard on the limited edition Mitsubishi Pajero Field Master (the most stolen vehicle here).
