What happens when you put two spark plugs on the same cylinder?
But when you have two spark plugs on opposite sides of the cylinder, the fuel-air mixture burns from the edges of the cylinder, moving inward.
Why does a hemi engine have 2 spark plugs per cylinder?
With the quest for more and emissions playing a big part the “new” Hemis have two plugs per cylinder. This cleans the emissions up for the Hemi. Why do aircraft engines have two spark plugs per cylinder?
What are the benefits of having two spark plugs?
There's another major benefit to having two spark plugs per engine, and that is power. When two spark plugs fire at the same time in a cylinder, you get something called a "twin flame front".
How do dual spark plugs work on a piston engine?
Piston aircraft engines often have dual plugs and dual magnetos. An instrument panel switch, often combined with the starter switch, allows the pilot to alternatively select both or one or the other of the two magnetos that energize the dual plugs.
Why do some rotary engines use two spark plugs?
Most rotary engines have two spark plugs. The combustion chamber is long, so the flame would spread too slowly if there were only one plug. When the spark plugs ignite the air/fuel mixture, pressure quickly builds, forcing the rotor to move.
Can there be two spark plugs per cylinder on a 4 stroke engine?
In most cases, four-cylinder engines have 1 spark plug per cylinder. A fair number of engines feature more power. There is more to it with Alfa Romeo Twin Spark engines. There are 2 spark plugs per cylinder, which is what it sounds like.
How does a twin spark engine work?
Two spark plugs placed diametrically opposite to each other in the combustion chamber fire simultaneously igniting the charge. The benefit of this concept is improved fuel economy, better drivability, and reduced engine on a emissions.
How many spark plugs should there be for each cylinder of the engine ignition system?
two spark plugsSpark plugs provide the source of ignition. Each cylinder has two spark plugs which improves combustion of the fuel/air mixture, results in a slightly higher power output, and provides redundancy.
Is twin spark better?
The logic behind this technology is that two spark plugs can burn the fuel/air mixture much quicker than a single spark plug by ignition at two different points at once thereby giving twin spark engine cars a greater efficiency.
What engine has two spark plugs per cylinder?
Several modern Mercedes-Benz engines also have two spark plugs per cylinder, such as the M112 and M113 engines. Some motorcycles, such as the Honda VT500 and the Ducati Multistrada, also have dual ignition.
Are twin spark engines good?
Variable valve timing gave the Twin Spark engine very good performance for its cubic capacity, but it is one of the weaker areas of the 16-valve engine. The original variator that controls the cam timing is prone to wear or jam, although replacement part carries a different part number and has improved reliability.
What is Twin Plug?
Adjective. It is a word used to refer to someone who is bi-sexual.
What is meant by DTS i engine?
DTSi, or Digital Twin Spark Ignition System, is a technology developed and patented by Bajaj Auto Limited. It was first used in their Pulsar and Avenger models. At the time of its introduction to the market, it was considered revolutionary as it both saved fuel and improved engine performance.
How many spark plugs do I need for a 4-cylinder?
4 spark plugsTypes of Spark Plugs For example, if you drive a 4-cylinder engine, you need 4 spark plugs. To go along with engine fit, most spark plugs get made from different types of metal, some being cheaper than others.
Does a 4-cylinder car have 4 spark plugs?
If you have a four-cylinder engine, you will have four spark plugs, and so on. It is here that they receive an electrical current from the ignition coils. Next, they create the electric spark that ignites the compressed air-fuel mixture in the combustion chamber.
How many spark plugs does a V8 HEMI have?
Most V8s have eight spark plugs — one per engine cylinder. However, twin spark engines with no distributor, and newer HEMI engines with MDS (Multiple-Displacement Systems), will have two spark plugs per engine cylinder — so sixteen in total.
Why do cars have twin spark engines?
A Car brands have invested many billions in trying to efficiently combust all the fuel injected into the cylinder in an effort to improve performance and/or reduce fuel use . So-called twin-spark engines were designed to do just that.
Does Alfa Romeo have a spark plug?
Alfa Romeo marketed the technology heavily with its TSpark engines before reverting to a single spark plug for even more efficient new-generation engines.
Why do you need two spark plugs?
There's another major benefit to having two spark plugs per engine, and that is power. When two spark plugs fire at the same time in a cylinder, you get something called a "twin flame front". That means that instead of your fuel-air mixture igniting from one point in the cylinder, it ignites from two separate locations on opposite sides of the cylinder.
Why do airplane engines have two spark plugs?
By having two spark plugs per cylinder, your aircraft engine is more reliable, produces more power, and burns fuel more evenly . And when you combine all three, you get an ultra-reliable engine that keeps you aloft until you decide it's time to land.
How does a spark plug work when it is only one spark plug?
When you only have one spark plug per cylinder, the fuel-air mixture burns top-down from the center, moving outward. But when you have two spark plugs on opposite sides of the cylinder, the fuel-air mixture burns from the edges of the cylinder, moving inward. This even burn helps prevent hot-spots in the cylinder, ...
What happens if you only have one spark plug?
Let's say you had a spark plug stop working in-flight. If you only had one spark plug per cylinder, you would lose more than 25% of your power, if you were flying a 4-cylinder engine. And if you've ever flown a small single-engine plane, you know that a power decrease like that could mean the difference between cruising and not being able to maintain altitude.
Why is it important to have a fuel air mixture?
This is important for two reasons: 1) the fuel air mixture burns more quickly, and 2) the fuel air mixture burns more completely. And when you have both of those things happening in your cylinder, you get more power, which is something almost every pilot is looking for.
Why burn a cylinder?
This even burn helps prevent hot-spots in the cylinder, and distributes pressure more evenly across the cylinder, which is important with the big, high-compression, air cooled engines found in most airplanes general aviation airplanes.
Can you have two spark plugs on a dual ignition?
By having a dual ignition system with two spark plugs, none of this is a problem. If you have a magneto fail, you'll probably see a slight drop in engine RPM, but the other magneto, and the spark plugs that it's connected to, will keep firing on all cylinders. And if you simply have a spark plug fail? The same thing happens.
How does having 2 plugs per cylinder increase the power of an engine?
However, having 2 plugs per cylinder increases the power of the engine by making sure as much fuel is burnt as possible, leaving less un-combusted fuel to go out the exhaust. The 2 plugs are placed as far apart as they can, so that as much gas can be burned. 8 clever moves when you have $1,000 in the bank.
Why do hemi engines have 2 spark plugs?
More or less, modern Hemi’s have 2 spark plugs per cylinder to help the car get better combustion, and thus more power and cleaner emissions. Unlike what others may think, modern Dodge engines with the ‘Hemi’ badge do not have the hemispherical combustion chambers that gave the original Hemi’s their name. However, having 2 plugs per cylinder ...
How many spark plugs does a car have?
It depends on the engine. Some have no spark plugs. Some have 1 spark plug per cylinder. Some have two and some even have three.
Why did the 1920s have two spark plugs?
Moreover, the Dual Ignition design made it less likely that any individual fouled plug, a very common problem in the 1920s and 1930s, would cause a miss, or that high compression under load would “blow out” a spark when there was a weak coil or the eroded spark plug gap was too wide .
How many spark plugs did the Silver Ghost have?
In the Silver Ghost engine the plugs had separate and independent ignition sources. Six of the twelve plugs were energized by a conventional battery points and coil ignition. The other six spark plugs were separately powered by a magneto.
Why is dual magneto redundancy important?
Although there can be performance advantages to this dual plug/dual magneto design, the primary reason for the redundancy is reliability and safety.
Why did Nash use 16 plugs?
Why did Nash choose to use 16 rather than 8 plugs? There were a number of issues. The first was one of fuel quality and especially volatility. Automobile gasoline available to motorists in the 1920s and 1930s was not only poor quality, that quality was variable. (Note that during the war years fuel quality was even worse.) And one of the big problems was fuel volatility, especially at cold ambient temperatures. That problem was exacerbated by long intake manifolds in which some of the fuel/air mixture could condense in the manifold leading to lean mixtures, of already hard to ignite fuel, reaching the end cylinders on a block.
Why use a second spark plug?
By using a second flame front provided by a second spark plug, the distance traveled is reduced, as is time for the mixture to completely burn, and this tends to more completely burn the fuel/air mixture. This reduces hydrocarbon emissions, lessens detonation issues.
Why do you need a second spark?
A second spark reduces the odds of that happening, the 1 in 100 odds drop to perhaps 1 in 10,000 and make for a smoother feeling engine and better emissions performance. It's mainly emissions that's the problem for a bike engine, a car can have a large enough exhaust and cat to get rid of the effects of unburned fuel before it exits the tailpipe, a bike, not so much.
What is dual spark technology?
Suzuki’s Dual Spark Technology, unique in this class, utilises two spark plugs per cylinder for precise ignition. Combined with the newly adopted high-ignition nickel spark plugs, it contributes to increased combustion efficiency, smoother power delivery, lower fuel consumption and lower emissions.
How to get fuel to ignite properly?
To get fuel to ignite properly you need the correct mix of fuel and air at and near the ignition point and a source of heat, like a spark.
Does Suzuki use budget brakes?
Not sure I agree with this, as all the motorcycle companies are fully embracing "good technology" IMHO. Suzuki saves money by using budget brakes and suspension, plus whatever else in the parts bin can be transferred to another model, this is a pretty common practice all around. The Stroms for example are being improved with every edition, they can hopefully only get better. :fineprint:
Does the GSXR have 2 SP heads?
I think it may decrease horsepower though. GSXR's don't have 2 SP heads and pass emissions testing.
Why do race cars use Exstream ignition?
when the spark plug's fire under exstream presure, they actully losse some of there power , thats why race cars and 1000hp dragsters use such exstream ignition and coil set ups. the stock coils just dont have enough umph to give the hotest spark, thats why the 6.1 and the crate motors have a biger coil pack. the more compresion and fuel, the more spark power is needed. like i said, shorty wire loose power, granted its not much lose but its a lose. unless your going to run nitrues then the lose is a good thing.
Who has 6.1 coils?
Hemiwoods from Virtual.Dodge has the 6.1 coils on his truck. Some pics as he installed, tied them in and then wrapped them.
Do you need oem wires for Nitrous?
04 I think. I believe its more to do with the fact that he was running nitrous. You need to have oem wires, Taylor or other long wires or coil packs to properly run nitrous. The shorty wires cause problems with nitrous, they blow the wires right off.
Does Bosch 4.7L run like Shizz?
Return the Bosch plugs and get some NGK's.Bosch made my 4.7L run like shizz.NGK's just idle nicer and the truck feels alot better.
Why do cars have spark plugs?
Full combustion results in heat, water, and carbon dioxide. NOx emissions are only significant during incomplete or partial combustion, due to the lack of available oxygen, high temperatures, and various chemical reactions. That's why catalytic converters have been standard on cars for the past three decades. The extra set of spark plugs on the HEMI and on previous engines are designed to reduce emissions before a catalyst is needed. They add some horsepower, but not very much.
Why do plugs fire during power stroke?
The extra plug fires during the power stroke to more fully burn the hydrocarbons. The second ignition allows additional power in the down stroke while lowering the need for restrictive catalyst plates in the converter.
What is the coil pack on a Hemi engine?
Each cylinder on a Hemi engine has an ignition coil pack over one spark plug, and a regular plug wire connected to the other spark plug. Further, the coil pack also has a plug wire attached to it that extends to the opposite cylinder bank.
How does a cylinder fire?
Each cylinder shares a coil pack with another cylinder. Each of the two plugs on a given cylinder is fired by a separate coil. One plug has a coil directly attached, and the other is fired via an ignition wire connected to a coil located on another cylinder on the opposite bank.
Why are NOx emissions only significant during incomplete or partial combustion?
NOx emissions are only significant during incomplete or partial combustion, due to the lack of available oxygen, high temperatures, and various chemical reactions. That's why catalytic converters have been standard on cars for the past three decades.
