E Logo on F1 cars?

ELECTRICITY???
related to the KERS system.

 

The E logo indicates the positioning of a safety device that kills electrical power in the car. It's really to indicate the marshals where it is so that they can turn it off when they need to.

And N is for the device to put the car in neutral.

 

As an SCCA corner worker when I see an "E" sticker, it means that's where I can activate the fire suppression system if the driver hasn't already. (E=extinguisher) The sticker looks like the pic below. The second sticker is to indicate where the master switch is to kill the power. You might also see a red circle on some cars with a white "T" in it, which is the location of the transponder. Finally, the "Tow" sticker and/or arrow is probably pretty self-explanatory. The fire, kill switch, and tow locations must be clearly marked on just about every type of competition car as far as I know.

Thanks.

What is the meaning of the N sticker? A switch to put the car in neutral to remove it from the spot?

PS: The 2002 F1 Ferrari has a E and a N sticker.

 

Yep - although I've never worked an F1 race it's my understanding that there is a switch/button in the location of the N sticker so safety/corner workers can engage neutral to push the car. (We don't run into too many "paddle shift" cars in SCCA.)

 

Not related to KERS, just the standard "push here to switch the electrics off".

 

Maybe things are different down here in the States, but see my post #5 above. Now I'm curious. Is the "E" on an F1 car different than the "E" for "extinguisher" on every other race car?

 

E - for the driver/marshals to kill the electricity to prevent a fire during an accident. Normally located near the fuel tank area.

N - Neutral, specifically for marshals, to show them where to hit the neutral button in case the car is in gear, in order for them to remove it from a dangerous spot.

 

I think I'll probably not bother answering again....... :?

 

I've heard it explained by a few commentators like Martin Brundle {ex driver of course} and the couple of guys on Speed, Steve Matchett, David Hobbs and the hair guy. They also went over the other symbols on the car.

It's a different series, so they can have different rules, guidelines and safety precautions.

 

Wow,

This is a classic case of a "myth" becoming reality via "weight of public opinion". Problem is, most of the above is *wrong* ("Electrical shutoff" - Fail! KERS "stuff" - fail!.....)

"E" - stands for "extinguisher" and, if pressed [EDIT, or possibly "pulled"], will fire the onboard extinguisher system. [*Nothing* to do with the electrical system.]
"N" - (Should) engage neutral to allow the car to be pushed.

The "E" requirement has been around since the dark ages BTW.

Ed, 100% agree with your OP: "E" for extinguisher, "lightning bolt" for electrical power. This is not geographic location dependant - Track workers are (usually) local, and this is one standard they all *know*.

However, I'm curious, why would a track worker be concerned with the location of the transponder?

TIA,
Cheers,
Ian

 

As a corner worker I could give a rats a$$ where the transponder is. However, I think some regions make them put the "T" sticker on to identify the transponder location to the tech inspection guys and timing & scoring. I've never seen the "T" sticker personally, but I hear it is used in some regions in the South.

 

That's what I suspected, but figured I'd ask - Thx for the response.

Yep, that makes sense.

cheers,
Ian

 

No, that's the master switch, and its position is indicated by the lightning symbol Ed posted.

 

Nop ! The E sticker indicateur de fire extinguisher for marshalls for electric cutoff the stickers look like a blue triangle with a red lightning inside

 

Technical Regulations 2019 - clause 14.1.8

Any triggering system having its own source of energy is permitted, provided it is possible to
operate all extinguishers should the main electrical circuits of the car fail.
The driver must be able to trigger the extinguishing system manually when seated normally
with his safety belts fastened and the steering wheel in place.
Furthermore, a means of triggering from the outside must be combined with the circuit
breaker switches described in Article 14.2.1. They must be marked with a letter "E" in red at
least 80mm tall, with a line thickness of at least 8mm, inside a white circle of at least 100mm
diameter with a red edge with a line thickness of at least 4mm.

 

Master switch :
14.2.1 The driver, when seated normally with the safety belts fastened and the steering wheel in
place, must be able to cut off the electrical circuits to the ignition, all fuel pumps and the rear
lights by means of a spark proof circuit breaker switch.
This switch must be located on the dashboard and must be clearly marked by a symbol
showing a red spark in a white edged blue triangle.
