But also useful for priming the oil system. Indeed even on early FI cars like K-Jetronic you could wire a switch to the fuel pump to prevent firing.

    Great video. Most of the issues with start up wear disappear if you run the engine on LPG instead of petrol. It's a big urban myth that engines won't start cold on LPG, actually the complete opposite is true, no enrichment required and they start instantly. Because the fuel always enters the engine fully vaporised even from cold, no bore washing occurs. Additionally because the fuel supply can be turned on/off instantly (not possible with a carburettor) I can crank the engine on the starter without fuel until oil pressure builds, then turn on the fuel and the engine starts immediately, virtually eliminating the bearing wear problem. It's a fantastic fuel for classics, I can never understand why it is so unpopular, with petrol currently £2 a litre but LPG in some places still under 70p, maybe people will wake up to it again..

    Great stuff. I have always resisted temptation when starting any engine. Always been mindful of the oil circulation. I had a neighbour with a lovely sounding throaty V8 TVR, but he knew nothing about cars. For several years he would start it from cold and instantly fling it up to very high revs like a teenage boy. Then before it even had chance to warm up, he'd switch it off. An hour later did it again. He did this multiple times per day each summer weekend for several years. Eventually, it went from sounding really sweet to sounding like a washing machine full of knives and forks. He has not started it for at least 5 years now. I am certain he trashed the bearings. I am also certain it was for all the reasons Ian describes here. Great video.

    If only I'd known at the time that my BL Marina wasn't supposed to start when you turned the key in the morning, needing to crack the motor over for several minutes before it started was in fact a design feature to prevent premature engine wear, as was the need to apply copious amounts of WD40 to the engine compartment the surplus oil enhanced the rust proofing filled the cabin with that unmistakable WD40 aroma!
    Being serious an ignition kill switch might be useful as it would allow you to crank the engine over building up some oil pressure before starting and if hidden under the dash could double as a cheap anti theft device.

    If you have an old fashioned immobiliser as was fitted in the 80s/90s, activate it, turn the engine over several times, deactivate and start the engine which allows the oil to be primed around the engine

    • @CaptHollister
      @CaptHollister 2 роки тому +1

      Depends if the immobiliser cuts the ignition or the fuel. If you get fuel with no ignition, as was the case with my wife's 90s Civic, you will drown the engine and even get fuel in the oil.

    • @aston-martin-internationalist
      @aston-martin-internationalist 2 роки тому +2

      As above, a lot of immobilisers work by cutting the ignition. Most fuel injected cars of that time have an easily accessible fuel pump relay, just pop that out and turn over to prime.
      My Aston has a feature whereby on cold start from long layover, you can depress the accelerator fully and press the start button and it'll turn the engine over without firing. Aston actually make a note of those also in the handbook. I guess these types of vehicles see less use than regular daily drivers - but still, it's a nice feature. If I haven't used mine for longer than a 3 or so week interval, I'll used this feature to build pressure before then actually starting.

I bought a 3.5hp lawn mower years ago for $150 and modified the throttle to allow for a healthier warm-up procedure. Last weekend I coached a friend on starting his 2-stroke 6cyl boat engine regarding tapping the electric choke button to keep it running just after starting as on many engines like those die if the choke is on for an extra few seconds and die with the choke off for a few seconds.

    On something that's stood long time it can be worth taking the plugs out and spinning the engine on the starter until the oil pressure comes up, then put the plugs back in to start. That way there's no compression so very little load on the bearings. Of course, this does depend on the car being one designed for fairly easy access to the plugs

    • @guymonty96
      @guymonty96 2 роки тому +3

    Hi Lain , You have no idea how much I appreciate your channel , and this particular tutorial on starting/worm up engines. Since young age I had interest in cars and engine functionality. Just as I personal prospective, and by nature been over carrying for my personal stuff, I developed an interest on extending engine life, especially if I build it, . I then search into this subject, after experience at work, during maintenance on a paint industry, on the routing starting of a generator, every six months, just for to keep it in good working other . This is a big ex little ship four Cylinders diesel engine where I used to walk between the Cylinders, and the conrods where exposed. Before occasionally starting it, we used to pressurize the engine oil with a "not a small V8 diesel engine", that in turns (because itself also wasn't started often), with the add of a hand pump, we used to PRELUBRICATE IT , and create an oil pressure in to it before starting it...... Say no more!!! Since then, I starting research in engine pre lubrication, and I Found this video on big container ships engines starting, to witch no matter how big the oil pump would be, by the time the oil would lubricate the critical parts and Create a (CUSHION OF OIL BEARING), the engine would almost disintegrate in no time!! Since then and still in my younger age, whenever I rebuild an engine, I create a secondary oil pic up, from the oil pan "between the crankshaft", ( but not necessary from there), it could be a pic up from the oil pan as well, as long not from the very bottom or dirty oil would be picked up). Then sucking engine oil trough a filter (of any car brand) into of any OUTSIDE Block gallery, with a quality non return valve, ( because once the engine will fire, (if without the non return valve), it will loose oil pressure back to the oil sump) On my last beautiful Ford V8 351 cu", engine , I used a forklift pump, it happened to be a 24 Volts pump, ( but it don't have to be a big electric motor, a simple and small one would do.) In my case it was convenient because it has a gear pump already attached to it. all I had to do was to attached a small (Toyota) oil filter with an after market attachment, on to the same gear pump and no matter how long the engine hasn't been started,....... in a few seconds of the electric switch activation , the oil pressure goes sky high , and when subsequently I start the engine, it starts as smooth as a baby bump, without hydraulic lifters noise as they usually do make noise well after 12/15 hours the engine hasn't been running, if no pre pressurising the engine.. I know by facts of the big difference, as I only can tall the difference. As a matter of facts, this pre lubrication/pressure, pump it only needs to be operated only once daily, usually in the morning, (or after years stud still). This is the crucial time needed, to keep the engine lubricated before initial starting after approx.. a 15 hours rest......! Thinking that we got in the past to remove the distributor before engine starting after long engine rest, and spinning the oil pump with a drill, (on here we could of course) and after reassembling the distributor , tuning again the engine. When I was a very young fallow in Italy , I learned way Alfa Romeos would take their time for the engine starting. I am going back in the late 50s. The reason is because they have a simple and very affordable oil pressure switch that would delay the electric power to reach the spark plugs until the oil pressure would close the contacts . The same electric switch used by regulation on any ricing cars today operating electric pumps in case they roll over, to stop the petrol, or any combustible fuel to continuing pumping. Easy to purchase it from any ricing car industries. From $ 80.00 to $150.00, circa, the work all just as good!! it won't pressurize the engine like a pump such, but at list lubricate the engine ready for the conrod smashing the big ends bearings !! How much you LOVE your engine, since the major wearing is when you starting it????

    For a car that’s sat awhile, I was taught to disconnect the coil and crank the engine, while counting to 5 then stop for a few seconds. Repeat this until pressure shows on the oil pressure gauge (to keep over stressing the starter). Then reconnect the coil, set the choke and start the car. You can then set off, but do not over rev until the temp gauge begins to move. I follow this procedure on my 1965 TR4A.

    An excellent piece this. I have a few things to add. Bearing lubrication is critical, but having a background in competition engines it is also important not to idle too slowly because you can take out the cam lobes unless they get a good supply of oil. The cam lobe is the most highly stressed part of an engine in terms of the contact pressure it has to bear between the sliding surfaces of the lobe and the follower. We would always get oil pressure by cranking with spark plugs removed, fire up and run at around 2500 to 3000rpm with no load on the dyno until fully warm. A road cam profile won't be quite so demanding, so I agree with your lower rev advice for a standard engine. The worst (other terrible engines are available) offender here was the Pinto which had its camshaft suspended in mid air, miles from any oil supply (OK, they did eventually fit an oil spray bar but they were still notorious for knocking out cam lobes), whereas modern 16V engines generally leave the cam lobes and followers sitting in a nice puddle of oil once the engine is turned off. Incidentally, the easiest engine I ever dealt with here was the works Chevette HS engine. We ran an external oil pump driven by a belt and it was a simple matter to slip the belt off and turn the pump with a speed brace on the dyno - full oil pressure and the engine hasn't even been turned over!
    You will have confused some viewers at 10:40 when you said there were no chokes, but all 12 chokes needed fuelling! The cold start choke is a completely different item to the venturi choke in the carb barrel - but you know that anyway. Just pointing it out for anyone just learning.
    One thing that you covered rather briefly here is what you do with the throttle. I've lost count of the number of times I've seen someone start an engine from cold and then constantly blip the throttle to let the revs shoot up and down. Sounds great, but to anyone who knows what they're doing they just look like an ignoramus. Even some people who should know better have been seen to do this. Whether you have an ancient or modern, almost all engines have transient enrichment to richen things up as the throttle is blipped. An old engine will have a throttle pump and a modern will have an enrichment curve in the software. This is a disaster for bore and piston ring wear. The only engine I know of without this enrichment is in my lawnmower and that's a bugger to raise the revs on without it stalling.

    • @iain_tyrrell

      Great info, Roger. And knowing that more modern engines allow the cam lobes to sit in an oil puddle on shut down seems like great common sense design.
      Something I’m always mindful of if I’ve parked on a very steep hill is the position of the oil pickup in the sump as it may not be submerged in the oil depending whether you’ve parked facing up or downhill. I always try to roll to flatter ground before start up if safe to do so.

    It's great to see someone knowledgeable addressing the subject of oil starvation upon cold start up, and the dynamics are similar for practically all types of engines. I first was introduced to this topic during my stint as the driver of a touring top sportsman/pro modified drag racing team. When I was to start the engines, I had to crank the engine on the starter until the oil pressure gauge sustained at least 30 lbs of pressure for about 10 seconds, then hit the ignition and fuel switches to light off the engine.

  • @jdmjesus6103
    @jdmjesus6103 Рік тому +6

    The biggest factor in engine wear in my experience is oil quality. Oil choice and age can be what kills an engine (and usually is, long before cold starts come into play). Good video though, I learned why the nearest bearing fails finally! I always put it down to dirt getting though the pump but that makes sense too.

    • @djwmunro

    Good info. Many of these tips are also appropriate to Lycoming & Continental piston aircraft engines. At 1:45 Iain says on cold start "engines need a much lower fuel to air ratio". I think the intent is the opposite: more fuel, less air. A richer mixture is higher fuel to air ratio, lower air to fuel ratio.

    Some modern engine management systems incorporate a flood-start sequence. For a dead start after a long rest, hold the throttle to the floor and crank. The engine will turn but NOT start as long as the throttle is fully open as fuel delivery is bypassed. (Obviously, not something to try with a carbureted car). Start the engine normally once the clatter sounds "normal".

    • @jonathanrabbitt
      @jonathanrabbitt 2 роки тому +1

      On a carbureted car with a manual choke and fixed jetting, holding the throttle wide open during start will extend the cranking time before firing with the mixture being very lean (due to the low venturi velocity).

    The subject of initial oiling has long been a interest of mine, the absolute best way as far as my research shows is to have both a oil pre heater, and an independent oil pressure pump to circulate oil before the engine is turned, this system is used on most WWII aeroplanes with RR Merlin engines and works very well, there is a big market out there for a compact unit to fit on classic cars, or you can just isolate the ignition and turn the engine over a few times before turning it on.
