One of my first cars was a used 1970 Subaru 1066 cc, 4-speed manual trans, which gave me more than 40 miles a gallon for the 13 years I had it. The NGK long reach plugs always had a soft tan colored residue on each of the the spark plug insulators. I was amazed how well designed the engine was and how well it ran, giving so much efficiency using old technology of carburetor, copper core plugs, ignition points and required valve tappet adjustments. It was pre-catalytic convertor and ran on leaded gas for at least half of its life. It ran so cool that the muffler would rot out frequently due to condensed moisture for which there was even a drain port on the bottom. I got the idea to pour some paint inside a new one and fully coat its interior which extended the muffler life substantially and never even caught fire even!

It’s amazing how much spark plugs have improved in such a short time. Anyone who is at least 50 remembers when we had to clean or replace our spark plugs every few months/few thousand miles. These modern plugs will go 75,000-100,000 miles or more without even needing to be cleaned! I remember when you would pull them and clean/regal them every few months and they still would wear out and need to be replaced after a year or two. My current car has over 100k on it and I only replaced the plugs once! Honestly they didn’t even need to be replaced at 50k but I just got nervous and changed them out because I was worried they would get sized in the heads after being in there for 5 or 6 years! Anyone remember points? Yea we used to have to do a lot more maintenance on cars back then. Granted modern cars have lots of other problems and I’d gladly go back to points and the old plugs, it really wasn’t bad having to replace plugs and points every other oil change because those older cars were a lot easier and more pleasant to work on compared to these late model ones where you have to take half the car apart to get to anything. Leaded fuel didn’t help fouling but the real improvements are in the materials. Those old plugs just wore out the gap got bigger and bigger and after a few months it got so large that the engine started misfiring. When I pulled the ones out of my current car after 50,000 miles the gap was almost the same as a new plug! We’re talking about maybe 0.010 wear, those old school plugs eroded that much or more in 5,000 miles.

Some of us young folk still know how to take an emery cloth to a points dizzy! And truthfully, I agree with the sentiment behind going back to points and old plugs. I daily drive a 77 Mercury Cougar and do all my own maintenance on it. Oil changes, brakes and bearings, carb and timing adjustments, and most importantly diagnosis... I can do it all with simple tools and from the comfort of my own garage. Some people call me crazy for driving a gas guzzling land yacht but honestly I wouldn't trade that kind of straightforward, analog, accessible ease of work for a newer car. Hearing recently about Dodge's new non-serviceable transmission, in addition to watching a very disappointing video review of their new Hornet SUV (from a channel here on KZbin titled "The Fast Lane Car"), really made me take a step back from the idea of the modern automobile. In an age where planned obsolescence and reliance on technology are becoming more and more prevalent, I think it's increasingly reasonable to seek a product made at a time when planned maintenance and longevity were the premiere focus. I really do.

My father invented a self igniting spark plug, it contained a piezo crystal and used engine compression to put pressure on the crystal causing it to make a spark, a man from the patent office came to see the prototype in action and was impressed to see a 250cc engine running with the plug, it was to receive a patent but my father could not afford the fees at the time and it was shelved. The plug needed more development as i found out when i tried it in my Yamaha FS1E 2 stroke, i think the compression was too low, but it had potential even as a get you home device should your cars electrics fail, i see piezo electric ignition on model engines these days but they dont operate the same way my fathers did

A primary reason for the switch from distributor to distributorless ignition systems is coil life. Beyond the increased wear on distributor cap and rotor conductors, having just one coil limited the peak voltage by what the coil could recharge to. It doesn't take a long time for coil saturation, but when you have a six or eight cylinder engine running at higher loads and RPMs can cause issues. Having a coil only firing once or twice per complete firing cycle allows them to run cooler, last longer, and provide higher voltages.

That's an answer to a problem that doesn't exist. Old cars with distributors run every bit as good as cars with distributorless ignition. They maybe a percentage point or two less efficient, but they are far easier to service because there's no (expensive) module to burn out...and wonder where you're going to find a diagnostic tool to test it with. On top of that, a lot of companies are discontinuing replacement parts for those earlier distributorless systems, making the prospect of keeping cars from the 90s on the road much more of a challenge. Because the parts are more sophisticated, they require more volume in sales to justify their production. Older cars with simpler parts cost less to keep in the market place.

@@tempest411 This is probably one of the worst takes I've seen on this. Higher ignition energy is required for higher output engines, which modern engines are. We're talking cylinder pressures more typical of race engines in the 80s than regular cars. This higher energy puts more stress on any arcing part, eroding it faster. I have had a lot of experience with carbs, points, distributors, early electronics, early and modern distributorless, and fuel injection systems from K Jet to 2024 model year direct injection. I built several hot street engines, and once you're having to run an MSD or other high energy ignition, the cap and rotor life goes down to about 10k, and that's if it doesn't start arc tracking and misfiring. The "unreliability" of modules is a myth as well, a lot of perfectly operational ones were condemned as a black box that nobody understood, and diagnosis isn't hard once you've actually worked with this stuff for a while. I've got 30 years now across all these various iterations of ignition and induction, and I'd gladly take a 100k+reliable electronic system over having to adjust my carb because it's 2° warmer today, or I had to fill up at a different station.

Usually I had to change the plugs and wires at 75-90k, depending on the specifics of the use, and the engine at 200k. The oil pressure usually dropped way off around 220-230k, so it was preemptive. I replaced engines, throttle bodies, harnesses, transmissions, differentials, but not once did I ever have a computer failure. None of the Fords did either. Same with the Mercedes and Cummins diesel ones. Now I've been running a smaller fleet in the rust belt with the same company, only 31 vehicles, for the last year and change.

@@TheLtVoss Yeah, about the coil packs. Kinda helps when the mechanic that installed the last set of coil packs actually plugs in all the wires correctly. We had to pay like $120 for a new set of coils, only to end up with the mechanic botching the job and didn't have cylinder 1 plug wire properly plugged in. It was just kinda jammed in at about a 45⁰ angle under the rubber boot, bent the connector at the end of the wire, and ended up burning up the replacement coil pack due to arcing at the connection. We almost had no choice but to have the plug wires replaced due to that crap, which would have required removing the intake manifold and all that good jazz. But I managed to salvage it, at least they gave us the old set of coils and 2 of the 3 were still good. So I did that coil swap my damn self to make sure it was done right for a change, and I salvaged the plug wire by bending the clip back into shape, wire brushing it clean, and making quite sure all the plug wires were completely plugged into the coils this time. Saddest part is the mechanics that botched the job had just recently done all the surgery to replace all the plugs and wires, only to screw up one of the wires and burning out not one but two coil packs, from the same plug wire no less! Honestly I don't really know if that wire goes to cylinder 1 or cylinder 4, nor do I really even care, it's a double fire coil pack setup so either way works.

I know that it did its job as when the system started to fail, it began misfiring and stuttering, the system was there to extract more efficiency out of it and doing so at its limit with help of such sensor, but as it was early design of such thing, it was over-engineer and is damn expensive. Saabs are very reliable, but cost of repair is high, you got to stick to maintenance very strictly.

It was at the time more expensive to change the 4 coils on a VW/Audi 4cyl engine. Edit: The ION sense function and DI coil pack was put in production 1988 in 9000CD turbo.. But in the beginning they used to ION sensing for missfire and cylinder/Cam sync. 1993 they started to use the ION sensing for knock detection.

13:00 you claim that higher octane is lower volatility. This is incorrect. Shorter chains have a higher octane rating AND are more volatile. Hence propane having >100 octane, while obviously far more volatile.
@CarBleach3 ай бұрын
yes higher octane is more volatile because lower octane gas is heavier. but higher octane gas is more resistant to spontaneous combustion which is what i think he meant to explain.

Imagine a time when things were being invented but they had no real use for them at that time. "Hey guys, I've invented this thing that makes cool zappy sparks!". "Cool, what's it for?" "Um..."

No mention is made of the 1839 patent holder and inventor of the spark plug , Mr Edmond Berger, i wonder why.
@stuarthardee55108 ай бұрын
Unless ALOT of improvement is made in the range, recharge time and price of electric vehicles the spark plug is not going to disappear any time soon.

Very interesting. Thou from I read, no one is using ion measurent for detecting knock in commercial sense. Saab did, but it never caught on…?
@thiswillprobhrt8 ай бұрын
BMW used it on their s85 V10. Although that’s some time ago now. I believe Mazda skyactive uses it also.

Psa, iridium is better than platinum because it has a higher melting temperature

Edmond Berger, a freed slave, invented the spark plug in 1839. Berger is credited with the invention even though he did not obtain a patent. The spark plug is a key component of all engines, using electricity to pass a spark between two electrodes to ignite fuel and generate power.

Nice review of the technology. But don't play the stock market, as your forecast of the end of the IC engine due to BEVs is a pipe dream.

100% only clicked on the video to see all the "re-upload" comments. Was surprised one wasn't the top comment.
