First, please understand that it is a fuel to air ratio, or an air to fuel ratio. For a diesel engine, it may go as rich as 18 to 1 air fuel ratio. If the diesel engine goes much richer than that, it tends to smoke too much for most applications.A gasoline engine can go as rich as 9 to 1 air fuel ratio. This ratio is approaching the rich limit of combustion. Additionally, this air fuel ratio is richer than Peak power. This Rich of an air fuel ratio is done to cool engine components such as the catalytic converters, the exhaust valves, or the piston crowns.One last note, differing fuels will have differing air fuel ratios that represent Peak efficiency. A fuel that is highly oxygenated will run a much richer air fuel ratio. Whereas a 9:1 air fuel ratio for gasoline is very very rich, nitromethane is very happy at 1.7 to 1 air fuel ratio.
First of all petrol and gasoline engines are the same. Maximum air fuel ratio will be for diesel engines. Air fuel ratio of petrol engine can be varied from 9:1 to 21:1 depending on the requirement and for diesel engines this is from 15:1 to 80:1. Since stoichiometric air fuel ratio of petrol is 14.7:1 and diesel is 14.5:1, diesel engines never go to richer side and will be always running in the lean side to avoid smoke. This is one reason for higher mileage of diesel engines. Note that the above mentioned values are overall air fuel ratios and local air fuel ratio of diesel engines will be lower and in the combustible limit
Can I use methanol in a lawn mower engine?
Can methanol be run in a lawn mower engine? If it can, what kind of power can it have? My friend ran methanol inside the engine with 20% nitromethane and the exhaust turned orange. I would do just plain methanol. What problems could arise from this? I know methanol is clean burning and since it would be leaner, I would richen the air fuel ratio. Is it possible?
By not extracting every possible amount of power from it. Radio Control engines run on nitro and last just fine. Really it's no different than any engine design, except the charge has oxygen built into the fuel.
Why not nitromethane as automobile fuel?
first nitromethane is not a good fuel for an automobile as the fuel consumption is quite high. a top fuel dragster will use 22 gallons of nitromethane in one minute, sorry vicinic but you are wrong on the fuel consumption rate. with gasoline you have a stoicheometeric, this just means an ideal air/fuel ratio, of 14.7:1. meaning 14.7 parts air to one part gasoline. for nitro it is closer to 1.8:1. top fuel engines run on the verge of hydrostatic lock at full power. and the flames you see coming out of the headers is not oxygen, it is burning hydrogen. one more thing, top fuel engines are actually running as diesels for the last half of the 1/4 mile as the spark plug electrode have burned completely away. as for the expense of the fuel, it runs something like $50 per gallon these days, and the racers buy it in 55 gallon drums, which lasts two and one half runs. sorry but nitro is not a good alternative fuel source. i know this because we used nitro as part of our fuel mixture in the late 70's when were were running in the old fuel altered class at the drag strip. in those days the top fuel guys would use a mere 12 gallons of fuel per 1/4 mile pass, including the burnout and staging.
Interesting....A top fuel dragster wouldn't run on just the nitromethane without any oxygen. In fact, the air/fuel ratio is around 1.7 parts air to 1 part fuel.(Compared to 14.7 parts air to 1 part fuel for a petrol/gasoline engine!).The amount of fuel/air consumed by a nitromethane fuelled dragster during a run is staggering..! (An average of 3,000 Cubic Feet/minute plus around 12 gallons of fuel, per second).As for gasoline/nitrous-oxide without any atmospheric oxygen, you might be onto something! The nitrous-oxide is simply a way of introducing more oxygen into an engine (it's easily dissociable) which, along with extra fuel, produces more power. So, if all the oxygen were provided by the nitrous-oxide, it *might* work! Starting it & throttle control might be difficult!But, the basic idea works well enough in rockets...
Can I use Nitro Methane in my 2003 Dodge Neon instead of regular gas?
NO it isn't any longer risk-free ! it won't harm the engine yet will destroy the gasoline device rubber factors. the only distinction between time-honored gasoline and E85 automobiles is in all RUBBER factors used to seal and carry rigidity for the gasoline pump/gasoline lines/ gasoline injector O-rings and the gasoline rigidity regulator. the vehicle could run positive till the gasoline device began leaking then you definately could go KABOOM !!!!! right it extremely is the interior song to back up my declare: are you able to adapt a time-honored vehicle to run on E85? no longer without a chemistry degree, money to burn, and numerous unfastened time. The supplies on your vehicle's gasoline device, alongside with plastics and aluminum, could desire to be designed to deal with ethanol. some factors, alongside with rubber o-rings and gaskets could positioned on out greater at present or go through harm, if uncovered to ethanol. Your vehicle's injectors additionally could desire to get replaced, alongside with the motor vehicle's computing gadget. The adjustments are rather low priced whilst completed on a mass production foundation on the production facility. yet we does not advise you attempt to retrofit a vehicle for E85 in the present day.
What can cause an air fuel ratio sensor to keep going bad in a 1998 Toyota Rav4?
I have had this car for about 5 years now, and the air fuel ratio sensor has needed replacement 3 times already. The car felt very jerky the first time, so I took it to Toyota where they found the problem and they replaced it. Then about 6 months ago, I was trying to pass my CA emissions test and failed because the sensor was bad again. It was replaced a second time. Yesterday my check engine light came on, and today Toyota diagnosed it as a bad air fuel ratio sensor again. This is the third time. What can make this continuously happen?? It is $600 each time for replacement, and I am losing my mind. Please help!
Can a stock production vehicle run on nitro methane?
No. Ideal ratio of air/fuel for a gasoline engine is 14.7:1 while the ideal ratio of a nitromethane fueled engine is 1.7:1. The stock fuel injectors and factory fuel maps would simply be unable to handle the volume even if the internal components could.
Can a car engine run on something that's not gas?
Kerosene requires more atomization than gas does, as well as a more powerful spark, on kerosene it may sputter a bit and smoke but it wont really run. Alcohol is way to hot when burned to run in a factory engine, plus it has no lubrication qualities. It will destroy an engine in a few minutes. I have seen factory Carb cars run on propane with great results, but its too expensive to need to done that way. Kerosene would be undriveable the car would barely start much less stay running. Alcohol can melt pistons, scratch compression rings and score the cylinder bore from lack of lubrication. DONT TRY THESE THINGS,o
