In this case, the alcoholic fuel is fed into the engine as a separate fuel and diesel is directly injected into the combustion chamber. Simple hydrocarbons such as methane, ethane, propane and octane are shown in (Figure 1) and are found in gaseous form. Also, take note of the octane numbers. imprint No data. var google_conversion_format = "2"; What happens during combustion is an interesting process. You can run higher compression ratios (up to 16:1 is ok, 13.8:1 is our ideal) if you wish but it works great on 10:1 too. A combination ranging from 100% water to 50% water / 50% methanol is sprayed into the intake of an engine. An immediate injection doesn't provide the same breathing space. DJ Safety, Most new vehicles that employ closed fuel systems will not have any problems. var _onload = function(){ These rules aren’t folklore created by fuel salesmen and the aftermarket; these rules all have a scientific reason behind them. & Injected Alky Engine. You should remind your customer of the 70/30 winter blend possibility and set the engine up appropriately. To learn more about these handy systems and whether or not your car can get one, go ahead and call us at (281) 492-0645 today. Alcohol-fueled engines emit carbon dioxide (CO2)and water (H2O). He’s a “gun-for-hire” for various OEM and aftermarket companies to design products, parts, CNC code and process improvement. It is cheaper. Stay up to date by signing up for the Engine Builder newsletter. Zoomie Headers. It is more susceptible to spark plug fouling, and as a result, it is not as popular, however E85 works well with mechanical fuel injection. }; This takes the simple hydrocarbon and makes what we call simple alcohols shown in (Figure 2). Thus, a methanol molecule’s atomic weight is 32 (4 hydrogens, 1 carbon, 1 oxygen) while ethanol’s atomic weight is 46 (6 hydrogens, 2 carbons, 1 oxygen). GENERAL RECOMMENDATIONS The bulk of the engines that utilize a normally aspirated alcohol injection system require an NGK–8 (Autolite 3934), NGK –9 (Autolite 3933) or NGK-10 (Autolite 3932) spark plug. if your engine is over 600 cu inches. This site has been var google_conversion_value = 0; But, an alcohol-based fuel will result in significantly reduced CO emissions when compared to a gasoline-fueled engine. Aftermarket cylinder heads, camshaft, and a forged lower end were assembled with the idea of digesting roughly 200-250 hp of nitrous oxide. fjs.parentNode.insertBefore(js, fjs); The above procedure may seem simple but actually requires practice and a keen ear. Well, you’ve probably experienced this phenomenon before. The water methanol injection process requires a leaner air-fuel ratio during normal operation, providing a higher level of efficiency for your engine. (function(d, s, id) { Between KillerRONS and Steve Schmidt Competition Engines there is literally daily experience with 10*, 12*, 14* and 18* engines and to date there have been zero issues related to the use of alcohol injection. As we continue to create longer chains, we go from gases, to liquids, to waxy solids. Alcohols range from a low of 106 octane to a high of 115 octane. surroundings since the car can lurch forward at any time. Illustration for Enderle Square Barrel Valve when using: Blown Gas, Blown E-85 or UnBlown any fuel (Not Blown Alcohol) Valve “A” 16-20 lbs. A dyno tuned engine with an alcohol injection kit will help maximize the power your engine can deliver. Enjoy all the advantages of water/methanol injection with one of our top-brand water/methanol injection systems. The article claims that water/meth injection increases power “…factor anywhere around 20% horsepower gains on a forced induction engine.” I would argue that a 350whp EVO is, if not an above average candidate, at least an average candidate for good gains due to water/meth injection, and the numbers above show a 5.7% increase in horsepower. /* ]]> */ He is as wizard in gaining performance while keeping vehicles within emissions standards. if (d.getElementById(id)) return; var google_conversion_color = "ffffff"; But, we already know with our Latent Heat Vaporization values of alcohol, we are removing a significant amount of heat from the chamber, so in effect, an alcohol motor is not temperature affected by timing increases. var google_conversion_label = "-DXeCK6WxgcQqNmu_QM"; If the engine is an older model with a carburetor you will need to increase the size of the metering jets to allow increased fuel flow. The addition of gasoline makes the cold starts easier so that heat may get into the engine and get up to temperature easily. All logos and images are reserved. Previous: Next: Side Effects. We offer Alcohol Injection Kits, Water Injection Systems, Water and Methanol Injection. Our friendly staff is always happy to provide inquiring minds a free estimate. The OH atoms that were added to the base hydrocarbon to create the alcohol break off and team with another hydrogen atom. 2. Static compression was set up at 12.5:1 with dynamic compression at 9.3:1. As the liquid enters the intake, it absorbs heat energy from the surrounding air and travels along with the air. var google_conversion_id = 1068215464; The main purpose of the oil is to prevent corrosion of water injection and fuel system components; it may also assist in engine lubrication when running in a high power state. fbds.src = '//'; This approach provides high substitution ratios and flexible operation based on the fuel availability—diesel only or dual fuel. Simply pull the alcohol carb, cap off the fuel feed lines that contain alcohol, bolt on the gasoline carburetor, and plumb a line from the fuel pump to an external fuel can. var js, fjs = d.getElementsByTagName(s)[0]; About the Authors: Norm Brandes owns and operates Westech Automotive, Inc., a machine shop and vehicle repair service business located in Silver Lake, WI. window._fbq = window._fbq || []; We were able to make significantly more power with a a properly designed and tuned E85 engine! Alcohol burns more slowly so it doesn’t build as much engine heat each run. The camshaft was set up for nitrous usage, so it bleeds off a lot of compression, yielding a very low dynamic compression value of 8.2:1. The engine will die if too much, or not enough gas is primed at the exact moment. Keys to low cost are the following: a standard opening small blower (not the more expensive delta lower opening) mechanical fuel injection hat with only hat nozzles (no port nozzles) for methanol fuel. SCE Gaskets, Remaining focused on the lambda values and not the readings on the air/fuel ratio meter is the first step to success. Pre-Owned Parts | An hour of time can give the body a nice cushion and prevent alcohol poisoning. Our first case study is a newly freshened GM Gen III engine. You probably also noticed that the engine runs quite a bit cooler when running alcohol. What causes this? var google_remarketing_only = false; The secret lies in the Latent Heat Vaporization, Autoignition Temperature and Energy of Stoichiometric Mixture of alcohols. Thanks to the adoption of direct fuel injection, teaming gas and ethanol has the potential to beat diesel efficiency. Physics dictates that a certain amount of heat is required to convert a liquid to gas. Why would you want to burn a fuel that has 60 percent of the available heat of gasoline and has incombustible water as a product of combustion? ga('send', 'pageview'); Search | pressure for unblown Gas, E-85 , Alky- Increase to 3-5 lbs. According to EPA studies, when using ethanol over gasoline: • Nitrogen oxides (NOx) reduced by up to 20%, • Emissions of Volatile Organic Compounds (VOCs) reduced by 30%, • Emissions of cancer-causing benzene and butadiene reduced by, • Significantly reduced Sulphur dioxide (SO2) and Particulate. Unfortunately, it is next to impossible to achieve a perfect burn, so as a result, carbon monoxide (CO) is also present, which is poisonous and is watched carefully by the EPA. We asked Lake Speed, Jr. of Driven Racing Oil about the the special requirements for engine oil when used with alcohol. Press Releases | A good rule of thumb is if it is a fuel and it burns, odds are it is in the hydrocarbon family. Milodon, As the load and rpm increase, timing also increases reaching its highest level around peak torque. This combination makes H2O, or what we know as water. You can continue to create these chains of atoms to achieve more and more complex alcohols. Performance Products | What this essentially means is that when the engine is setup to run at the given Stoichiometric mixture, a cubic foot of any of the four fuels will yield roughly the equivalent energy (94.8 vs 94.5 vs 94.7). The Blower Shop (TBS), Wilwood and This motor wasn’t a good candidate for running E85 on motor only, but, with the size of the nitrous shot, we forged ahead. Water/methanol injection for gas engines is a proven means for effectively reducing engine inlet air temperatures and suppressing harmful detonation on high compression naturally aspirated (NA) race engines. if (!window.__adroll_loaded){__adroll_loaded=true;setTimeout(_onload, 50);return} This is one of the reasons that we like to use supplemental alcohol injection on forced induction engines even if they are running gasoline. But it is an interesting thought experiment that helps to understand the effects of alcohol, so let’s watch the video. We know that gasoline will drop the chamber temperature about 40° F, therefore, ethanol will drop the temperature roughly 100° F while methanol will drop it roughly 135° F. Thus, at these Stoichiometric values, we see a significant drop in temperature of the air/fuel mixture. Another problem we ran into in the past was increased timing usually meant that the engine ran hotter and we’d have to design around this issue to cool the engine. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.The general chemical formula for alcohol fuel is C n H 2n+1 OH. var scr = document.createElement("script"); scr.type = "text/javascript"; } close to the turning blower belt. Looking at the open loop fueling tables we notice that alcohol requires more fueling with colder temperatures. Given that the atomic weight of water is 18, you can see that in the case of ethanol, 39 percent of the molecule cannot be burned and does not contribute to power added. But, on open fueling systems, or in instances where water has been introduced to the fuel system, adding benzene, acetone and butyl alcohol will increase the water tolerance of E85. Torque also increased (542.9 lb-ft at 6,300 rpm), although it … Alcohol Injected BB/Chev Pro-Filer 12 degree Solid Heads, Brodix Solid block, Callies Magnum 4.750 crank, Oliver rods 6.7 Diamond J.E. color colorless shape No data. What Would Happen if You Injected Alcohol? Therefore, we can use both narrow band and wide band oxygen sensors to monitor and trim fuel. Fast forward to 1861 where German inventor Nicolaus Otto, also known as the father of the modern four stroke engine, developed an internal combustion engine that ran on pure ethyl alcohol with a heated carburetor. Keith McCord is president of McCord Consulting Group in St. Louis, MO. ((document.getElementsByTagName('head') || [null])[0] || Max power jumped 39.8 hp to 655.2 at 6,400 rpm. created & maintained by Good Vibrations Motorsports. /* OPTIONAL: provide email to improve user identification */ We now have more alcohol to burn and a cooler air charge, but what about lighting the charge? Finally, with the increase in compression ratio, we also get more heat in the chamber, which equates to not only a better burn, but also better vaporization. Alcohol injection will work as good or better than a gasoline carburetor in most any normally aspirated engine regardless of runner positioning, valve angle or chamber size. Drug Survey. Gasoline has a heat value of 20,400 BTUs while ethanol has a heat value of 12,800 BTUs. If you’ve ever poked around an alcohol-fueled engine equipped with carburetors, you probably noticed that the intake runners are iced over during idle, especially if equipped with a large overlap camshaft. As far as unleaded race gas goes, there isn’t much available above 104 octane. _fbq.loaded = true; Henry Ford introduced the Model T to run on both ethanol and gasoline. DevilsOwn Alcohol Injection is the Best source for your Methanol/Water Injection System needs. (function() { })(); fbds.async = true; As a result, we have a much more knock-friendly fuel as compared to gasoline. As you know, this is an easy way to make more horsepower and torque in an engine. A peek inside a GM flex-fuel ECM reveals that there’s only one volumetric efficiency table regardless of the fuel used. To keep a fair comparison, we swapped to a 60 injector set and strapped the car to a Dynojet dyno and began tuning. Gasoline, ethanol, methanol, propane, butane, and kerosene are all included in the family of hydrocarbons. Ethanol, or moonshine whiskey has been used as either fuel or liquor since the mid-15th century. Only necessary crew This allows racers to reliably increase boost and advance ignition timing—without using high-octane racing fuel—for improved power gains. var _fbq = window._fbq || (window._fbq = []); (function () { Tests by the EPA have shown negligible differences in the above percentages when comparing ethanol (E100) and a blended ethanol/gasoline mixture (E85). [CDATA[ */ var js, fjs = d.getElementsByTagName(s)[0]; js = d.createElement(s); = id; A small hand wheel on the end of the starter is turned clockwise to engage the As more ethanol is sensed, the open loop fueling will be biased more towards the ethanol fueling table up to the point where we are running unmixed E85 only from the ethanol table. The ignition of the diesel fuel starts the combustion of the alcohol–air mixture. In the liquid state, the alcohol is very difficult to ignite and start the combustion process. One example is how GM handled its flex-fuel timing issues by creating an “adder” table where they either added or subtracted timing from the base gasoline timing tables. Control Cable, FIE, What allows this to occur is both fuels have a lambda value of 1.000 at stoich. Gasoline is used by some, but it is a bit harder to tune. if (window.addEventListener) {window.addEventListener('load', _onload, false);} Total Seal Rings, And one must always be aware of their As you can see in the video you posted the isopropyl alcohol will make the engine run somewhat, but the fuel was not entering the cylinder as a vapor which is the best way to operate a spark ignition engine. Both of these byproducts are extremely environmentally friendly and non-poisonous. (function(d, s, id) { if (d.getElementById(id)) return; if (document.readyState && !/loaded|complete/.test(document.readyState)){setTimeout(_onload, 10);return} Prolong, Why not use race gas? scr.setAttribute('async', 'true'); Billet Connection, Alcohol is less flammable so it is safer and easier to handle. ga('create', 'UA-214369-3', ''); }()); /*
