The spark plug in detail Electrode Gap EA EA Connector for the spark plug ( The illustra-tion shows an SAE connector , older vehicles are fitted with connectors with M4 threads ). A spark plug (sometimes, ... Other variations include using a recessed central electrode surrounded by the spark plug thread, which effectively becomes the ground electrode (see "surface-discharge spark plug", below). I then pulled the spark plug and it was melted. Read this crucial post to find the real reasons behind the melted car plug. The most common reason that we find is that the spark plug in any of the cylinder has melted. Hi guys, few days back my car was misfiring badly under full boost and the boost controller is set at 1 bar but once it hits 0.8bar, the car misfires and the boost bounces around 0.8 bar. Spark Plug with Oil Deposits – Besthomegear.com. The common reasons are many. Ones I've seen with only a burnt electrode had the piston melting. Pick up some merchandise at: https://lolfit.bigcartel.com They have no given heat range as the electrode design prevents the firing tip from overheating, and the insulator is flush with the metal shell to dissipate heat quickly. The steel pin (ignition pin) enclosed in a gas-tight fit within the conductive glass melt, Projected square platinum electrode (PSPE) spark plugs apply a square shaped tip of platinum to the end of a shortened ground electrode. All designs create a spark along the insulator nose to remove carbon build-up. Clean it by spraying your spark plug with brake cleaner, letting it soak for about 10 minutes, then wiping it with a clean cloth. Other manufacturers indicate loose plugs can be the cause due to vibration (NGK), also loose plugs tend to damage plug threads, as the thread is the point of electrical connection and loose plugs would experience intermittent grounding. Best Engine Air Filters: Our Top Picks in the Market, The issue does not go away even after you install some ngk platinum, after carefully tightening it by hand with some dielectric grease, Cylinder seems fine for a while; however, after being idle, the car stops, See if there is a hole in the piston of the spark plug. A taper cut ground electrode serves a similar function to a cut back ground, fine wire ground and angled ground electrode. Next time you see a melted car plug, relax! Add your valuable comments below. These gaps are never to be adjusted.) Furthermore, indicating the plug is in the correct heat range and has been operating in a “healthy” engine. Save Share. The fuel solenoid might be sticking closed. A yellow glaze on the spark plug’s electrode and the tip can inhibit conductivity, keeping the spark from being able to jump the gap. Ground electrodes come in a variety of shapes and sizes. Iridium, like platinum, is a precious metal and has extraordinarily superior properties for a spark plug electrode, for example high-temperature withstand, high strength, and … When the insulator becomes clogged with carbon, the ignition voltage jumps over to the side electrodes, enabling the plug to operate even under severe conditions. Developed for engines that tend towards increased carbon depositing as a result of their design, hybrid spark plugs have a standard ground electrode as well as two smaller ground electrodes on each side. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long. Surface discharge plugs may be required in high compression applications or with high energy ignition systems. Sometimes the end of the plug … Here, let us analyze common issues and find their solutions too. You could try to richen it up and add some TR7s.

Thus, if the engine design requires a side discharge plug, more ground electrodes extend plug life. This may be for combustion chamber design as in the case of a rotary engine, or a surface gap design as used in leaner air/fuel ratio’s on industrial engines. In an electrode for a spark plug, an elongated blank metal is made of a nickel-based alloy and including a front surface. It is important to note that multi-ground does not mean multi-spark, there will still only be one spark at a time. The nickel on the sparkplug doesn't melt until 2600 degrees.. Reducing the electrode size on a standard nickel plug would result in a drastically shortened life span, so smaller electrodes require exotic metals such as platinum or iridium to maintain (and at times surpass), the longevity of a traditional spark plug. Autolite uses a one-piece ground shield strap design on their HT (High-Thread) plug for improved heat transfer. Opened up the spark plugs and were shocked to find that plug #1 and #4 were melted while plugs #2 and #3 is seemingly fine. my 1991 pontiac grand am le is melting only one spark plug. Oversized electrodes are designed to withstand higher thermal and mechanical shock inherent with high compression motors. “These spark plugs melted and caused damage to our customers’ engines, which is annoying, costly and avoidable”, says Kai Wilschrei, Manager Technical Services Aftermarket EMEA at NGK SPARK PLUG EUROPE. Mineral Oil – Which Option Will You Choose? A smaller electrode also reduces flame quenching. knocking). A carbon-fouled plug will have black, dry soot on the electrodes and insulator tip. Most often car owners find that the spark plug in their cars has turned inefficient. Double fine wire electrode (DFE) spark plugs apply a fine wire pin to the ground electrode in addition to a fine wire center electrode. Complete a test for compression. The most common reason that we find is that the spark plug in any of the cylinder has melted. The U-groove cut in the ground electrode gives room for the spark to grow into a larger flame for greater firing energy and more complete combustion. Synthetic Oil V/s. The plug electrode did look fractured to me rather than melted though but I guess that could also happen from detonation. Cause: Overheating caused by auto-ignition. Some engine designs require the spark plugs have the ground electrode placed to the side of the center electrode rather than below as on a traditional plug. Replace the plugs if you have to, but check the real reasons behind the issue. See if the pump is in good condition. My ski was running real rough. Loose spark plugs pull air into the combustion chamber and lean that cylinder. Read this crucial post to find the real reasons behind the melted car plug. How To Solve 2000 Dodge Dakota Transmission Problems? Erosion at these points creates a larger gap between the center and ground electrodes, causing plug misfire. Check if you use an ECU program with no rev limit and the car is running lean. This ground electrode shape allows the spark to be focused between the fine-wire center electrode and projecting platinum ground electrode. Ground electrode variations include, PSPE (projected square platinum electrode). The aluminum piston melts at only 1250. Now it is running the same as before. The spark plug should be replaced. If the firing end of a spark plug is brown or light gray, the condition can be judged to be good and the spark plug is functioning optimally. Electrode Gap Metric Conversion Gapping Specifications (Bosch OE Fine Wire Iridium, OE Fine Wire Double Platinum, and OE Fine Wire Platinum Spark Plugs come with gaps pre-set at the factory. Double fine wire electrode (DFE) spark plugs apply a fine wire pin to the ground electrode in addition to a fine wire center electrode. E3 has taken multiple spark plug design features, such as cut back ground electrodes, sharp edges and surface gaps, and combined them to create a new ground electrode design. Its low profile design is resistant to vibration. Worn electrodes Note: The brown to greyish tan color and minimal amount of electrode erosion. A cut back ground electrode serves a similar function to a taper cut ground, fine wire ground and angled ground electrode. Check this post and get out of the problem with a smile. You have tried to replace it twice, and yet the issue continues. The wide gap improves ignition capability and is less sensitive to gap growth. If the plug has been used for too long, the insulator nose can be cracked by deposits between the center electrode and the insulator and from corrosion of the center electrode. it has quite a few miles on it and i need to know whats wrong with it. Therefore, these plugs are susceptible to fouling in cold applications. An electrode for a spark plug as recited in claim 1, wherein, when the slug is melted, a cone-shaped interface is provided between the firing tip and the end surface of the elongated blank metal. Carbon fouled. ・ As a countermeasure to increased stress on the ground electrode, changing to a spark plug with a small ground electrode is an effective way to handle the problem from the plug side. Cut back ground electrodes decrease the obstruction of the flame kernel to the air/fuel mixture, preventing quenching. Cars are the lifeline for all of us! Image 18: This damage is from impact, drop or pressure on center electrode. Caution should be made in selecting a "high performance" plug. You might even take a few degrees out from the timing. In a semi-surface discharge design, the voltage path skims across the surface of the insulator. NGK SPARK PLUG’s Technical Service team recently became aware of cases where customers bought CR9EIX NGK spark plugs on the internet, which proved to be fake products. You sometimes see a very bright white electrode with black dots on it also as a heat range issue in some cases cracked electrodes. remember that the wide band only picks up the integrated O2 ratio of the cylinders, A few cylinders can make a tough vacuum signal, The manifold design can rob other cylinders off the much-required, Do check your cars static compression ratio, a 150-hp shot seen in one system is totally different from the others, Pull out the plugs and inspect them carefully, The car might be either running on lean, or has too much ignition advance, or both together, Or the fuel filter is obstructed, or fuel pump is defective, Place the timing back to about 20 degrees, Replace the plugs if you have to, but check the rea, Most Common and Visible Issues, Top 10 Hidden Crucial Reasons. Appearance - Ceramic insulator tip appears to have a melted, glazed coating. Additionally the concave cut in the ground electrode promotes even gap growth. Once the plug has reach operation temperature and the deposits are removed, it returns to "normal" operation, with the spark jumping between the center and main ground electrode. ... Could have been a bad sparkplug but I've never seen a plug that bad. For instance, due to ignition being too far advanced, combustion deposits in the combustion chamber, defective values, defective ignition distributor, poor-quality fuel. Identify the stuff you use to retard or control the timing. Here, let us analyze common issues and find their solutions too. Surface gap plugs present the flame kernel to the piston (or rotor) more directly, reducing the travel time from the spark to the combustion gases. If your car came OE with a multi-ground plug, your engine will likely wear through single electrode plugs, especially fine wire plugs, at a rapid rate. Examples: 2-ground electrode plug, small ground electrode plug (taper cut), racing plug, surface discharge plug, etc. If you are very mechanically inclined you can try and pinpoint the problem, or take it to a qualified small engine mechanic to diagnose. Check if your fuel pump is going out. All trimmed designs have the same purpose: to reduce quenching and shadowing by reducing the surface area between the electrodes which could hinder the growth of the flame nucleus. Feeds the ignition voltage to the central electrode. Causes can include the engine overheating, incorrect spark plug heat range, a loose spark plug, incorrect ignition timing or too lean of an air/fuel mixture. Ground electrode variations include angled, cut back, DiamondFIRE, DFE (double fine wire electrode), flat, hybrid, inverted v-tip, low-angled, multi-ground, oversized, PSPE (projected square platinum electrode), semi-surface discharge, shield strap, side discharge, slant, square, surface discharge, surface gap, taper cut, tapered v-profile, trapezoid cut, trimmed side, U-groove, v-trimmed, and wedge shaped. When you are running a ported head, for instance, it may have a 5.7 head or not. This same design reduces quenching, which has a negative effect on the spark. Bosch Super Plus Spark Plugs also have factory-set gaps. A smaller electrode requires less voltage to jump the gap, resulting in fewer misfires, which translates to increased fuel economy and horsepower. I'd be watching the exhaust like a hawk for any signs of black smoke and listening for any sounds of detonation during the dyno pull. Check to see if the timing is controlled. Will be checking plugs again soon. If you doubt that the plugs are too heated, then that's the reason for the issue. Overheating of the plug causes the center electrode to expand, and this can break the insulation. Dry and Wet Fouling. E3's DiamondFIRE design features an open section at the top of the ground electrode, combining the benefits of additional sharp electrode edges with a cut-back electrode design. The increase of available edge-to-edge surface area encourages a more rapid spark discharge while also reducing quenching and shadowing. However, fundamentally, it is necessary to select a spark plug that matches the … Even if you change one of the spark plugs, it does not solve the problem! When the spark discharges, it burns off any carbon build-up. Normal Spark Plug Color. Standard spark plugs typically feature a traditional ground electrode. Its low profile design is resistant to vibration. Side discharge ground electrodes move the ground electrode to the side of the center electrode, reducing the obstruction of the flame kernel to the air/fuel mixture, preventing quenching, and presenting the flame kernel to the piston (or rotor) more directly, reducing the travel time from the spark to the combustion gases. Replace with a colder heat range of Autolite spark plug. The electrode tip of a spark plug presents a major source of auto-ignition. Its low profile design is resistant to vibration. A normal spark plug will have brown or grayish-tan deposits on the side electrode. A trapezoid cut ground electrode is a variation of a taper cut ground, which serves a similar function to a cut back ground, fine wire ground and angled ground electrode. A smaller electrode also reduces flame quenching. Many variations of the surface discharge plug exist, including the semi-surface discharge, intermittent gap, supplementary gap, and surface air gap plug. Photo 1: Broken ground electrode. If the engine is not performing properly and on removing a spark plug it is found that the electrodes have melted or the porcelain insulation has broken, this could be construed as a spark plug … All trimmed designs have the same purpose: to reduce quenching and shadowing by reducing the surface area between the electrodes which could hinder the growth of the flame nucleus. Most often car owners find that the spark plug in their cars has turned inefficient. Also known as an inverted v-tip, tapered v-profile, trimmed side, v-trimmed or wedge shaped ground electrode, all trimmed designs have the same purpose: to reduce quenching and shadowing by reducing the surface area between the electrodes which could hinder the growth of the flame nucleus. If the auto-ignition/thermal overload is bad enough, you can end up with simultaneous damage to the center electrode and ground electrode(s), and sometimes you end up with soft/spongy/cracked insulator tips (the white part). No power and wants to die. 5. An electrode for a spark plug as recited in claim 2, wherein the slug is in the form of pellet or powder. When you remove the spark plug from the first cylinder, you may find the following: See if the internal sides of the cap have any scratch. Should not use anti-seize on the threads, just proper torques. Heat can build up rapidly, and if it has no place to go it's going to do its thing on the air/fuel charge. See Spark Plug Gapping section. Inspect about the kind of shot it has, like 150.
