No.

ok :^(

That requires some sick tolerances druing manufaturing and some high precision machinery.

Plus some extreme voltage and current for the spark to jump with enough energy to ignite the fuel

>>5528

I understand it would be impossible (or at least extremely impractical) at the present. But if it becomes feasible in the future, it seems like it would allow for much faster and less inhibited ignition. It's similar to the reasoning behind side-gapped plugs, but taken to the greatest possible extreme.

I doubt it, if anything replaces current spark plugs it will be laser ignition.

No, just no, We could see pressure-ignited petrol engines.

I kind of want to try that now.

>buy a high powered laser for each cylinder, the kind that can set paper on fire

>change electronics so they're permanently "on" and run off the car's 12 volts

>remove ignition coil because you no longer need huge amps

>create laser-holders that screw into spark plug fittings

>connect lasers to spark plug wires so they laser for a split second as the distributor goes around

Why wouldn't it work? The biggest problem I can think of is the plastic housings of consumer lasers melting due to the heat.

>>5572

Besides the plastic housing, I doubt the internals of the laser could withstand engine temps for long periods or exposure to the combustion. Plus if they need to be replaced, you have to contend with the fact that good lasers are tens to hundreds of times more expensive than spark plugs.

You could probably do it with a decently sized gap and a very high potential.

Not sure if you'd be able to use a coil/transformer to get the potential up that high with a normal car battery.

>Distributor

Please, it's MUCH easier to use a coil-on-plug ignition.

>Distributor has air gap meant to be jumped by the high voltage discharge

>Spark plug wires are too high resistance to conduct 12v effectively

With coils on plugs you've got 12V drivers already in place for each cylinder.

>>5549

That's a great idea. We would be able to remove all the electronics associated with the ignition, and replace it with some sort of heating element that gets hot that only needs to be used when starting the car. We will need crazy high compression though, and maybe an iron block.

Hyundai is actually working on a gas engine that acts like this. It doesn't use glowplugs, but it has a cam timing that allows the combustion chamber to have more heat for the next ignition.

>>5608

iron block petrol engine?

Yea fucking right…

Just redisgn the alumicrap block with some structural reinforcing around the cylinders and maybe iron inserts for the head bolts…

Stupidest idea so far. Youll need a very powerful laser. Even the comercially available burning lasers arent strong. And those have a liffe cycle of about 10000 hours and way way less with the amount of heat in the engine

So think about it. Changing a $2000 laser diode every 5000 hours( being generous). Thats basically a $12000 tune up every 2-3 years…
