GASOLINE VS. ETHANOL
Gasoline makes one-third more energy than ethanol but by mixing ethanol and gasoline at a ratio of 85 to 15 percent the new fuel is around thirty percent less powerful than gasoline. Ethanol is similar in many ways to gasoline and produces similar effects when being used as a fuel, but ethanol get less miles per gallon than gasoline.
One of the main reasons to be against ethanol is that it causes damage to fuel systems and engines that gasoline doesn't. The most important problems are water contamination and fuel separation. The ethanol attracts water from the air and if it absorbs enough water fuel water contamination occurs in the car’s gas tank and that can have a prominent affect on engine performance. If you were to let the car sit for a while fuel separation occurs; the gas and water separate into layers and if the motor sucks the water layer into the engine,a lot of damage can happen.
Ethanol is pretty much just alcohol and alcohol can corrode the metal parts and the plastic parts in the fueling system. The main reasons to be for ethanol is that it produces less emmisions than gasoline and it is made from corn. Using ethanol is a huge money making opportunity and many advocates for ethanol are calling it "agribusiness".here.

BAD TRANSMISSION Solenoids then call JUNK CAR BUYER AUSTIN 512-789-2177
SOLENOIDS are pretty much just tightly wound metal coils. They're used in all sorts of machines, there are many in cars used for many different things including the starter. The starter solenoid receives two currents, a large electric current from the car battery and a small electric current from the ignition switch. When the key is turned to start the car the small electric current forces the starter solenoid to close a pair of heavy contacts and that relays the large current to the starter motor. Manual transmissions use the clutch to change gears but automatic transmissions use a complicated hydraulic system, and the transmission solenoids are essential for this process.
There are many solenoids in the transmission with many different jobs such as the transmission shift solenoid, lockup solenoid, or transmission control solenoid. They open or close hydraulic valves and regulate fluid flow depending on the speed. The speed sensors around the engine activate the solenoids to increase or decease the fluid flow and in turn the speed

BAD CAT AUSTIN TX CASH FOR CARS 512-789-2177
The combustion process of gasoline is never perfect and some small amounts of harmful emissions are produced in car engines. Catalytic converters are designed to reduce carbon monoxide which is a poisonous gas that is colorless and odorless, hydrocarbons or volatile organic compounds are a major component of smog, and nitrogen oxides which are a contributor to smog and acid rain and also an irritant to people.
Most cars are equipped to reduce all three of the regulated emissions through three stages. The first stage uses a reduction catalyst and it uses platinum and rhodium to rip the nitrogen atom out of the NO or NO2 molecule when it contacts the catalyst and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2.

WHAT IS A CATALYTIC CONVERTER?
A CATALYTIC CONVERTER IS A DEVICE ON THE VEHICLE THAT CONTROLS
EMISSIONS THAT TURNS TOXIC GASSES, AND POLLUTANTS IN EXHAUST GAS
TO LESS TOXIC POLLUTANTS. CATALYTIC CONVERTERS ARE USED WITH
INTERNAL COMBUSTION ENGINES FUELED BY GASOLINE OR DIESEL ALSO
INCLUDING LEAN-BURN ENGINES. THE CATALYTIC CONVERTER OFTEN LAST FOR
A VERY LONG TIME (10 YEARS) BUT CAN BE DAMAGED BY CONTAMINANTS, CLOGS OR
OVERHEATING. CONTAMINANTS CAN BE SOURCED TO LEADED GAS, WHICH CAN POTENTIALLY
DESTROY THE CATALYST.
A CLOGGED CAT CAN MAKE THE CAR RUN VERY SLUGGISH AND NOT GO OVER A CERTAIN SPEED AS DIFFERENT FROM A BAD TRANSMISSION. BUT WE BUY THEM NO MATTER WHAT IS WRONG WITH THEM AT JUNK CAR BUYER AUSTIN 512-7489-2177

VISABILITY IS VERY IMPORTANT FOR CARS AND TRUCKS AUSTIN, TX
.In almost all vehicles it is a legal requirment to have some form of windsheild wiper and yet it is a commonly overlooked aspect of car care. The blades of teh wiper are like a squeege, they pull the flat peice of rubber flush across the glass of the windsheild to clear away water and snow. But this is common knowledge, but many people don't know what actually has happened to the wipers when they aren't working anymore.
As the rubber gets older and is used more and more nicks and imperfections form on the edge of the rubber, when this happens it becomes harder for the wiper to form a clean seal against the windsheild and that's how we get streaks. Another way you might be getting streaks is if you have an uneven amount of pressure throught the blade. A ot of times this can happen when snow or ice sit on the blade and weigh it down in different areas.
In theory we would just push down harder or smoothing down that edge and our wipers could last much longer than they currently do but our cars our not programmed to use more force as our wipers age and it is not common car care to wipe the edge of your wipers.

What does “four cylinder” mean anyway?
When you talk about cars, “cylinders” comes up often. Four-cylinder usually comes up with smaller cars and is thought to be economical but not exactly powerful. Eight-cylinder comes up around men’s wagging tails and is usually associated with power and speed. But what exactly is a cylinder and what does it do for the car?
Long story short, a combustion engine works by pushing gas into a chamber - you guessed it- the cylinder, mixing it with air and then blowing it up. Now don’t panic, the car is not going to blow up. These explosions are tiny and expertly timed (that’s another article) to make the engine work. This process repeats over and over as the cylinders move up and down. The process can be broken down into four parts:
· Intake: Inside the cylinder is a piston. The piston strokes down on a rack that moves kind of like a bicycle pedal. The downward movement draws the air and fuel into the cylinder. At the bottom of the stroke, the valve closes, holding the air and fuel inside.
· Compression: The piston then strokes up in the cylinder and compresses the mixture according to the compression ratio of the engine. Ratios range from 8:1 to 10:0 for the most part, meaning the mix is getting squashed to a tenth of it’s original volume. Ratio varies, but the point is it's getting tight in there.
· Power: The fun part. At the top of the cylinder there’s a spark plug which does just that: sparks. The spark ignites the gas and the explosion makes the compressed mixture get lots bigger. The expansion of the vapor creates enough force when it pushes the piston down the cylinder that it turns the crank shaft to move the car.
· Exhaust: The clean-up. If you behaved like I did as a child, you know blowing things up makes a bit of a mess. Vapor is no different. Your cylinder is now full of burned gas, aka exhaust. When the piston is at the bottom of the cylinder, the exhaust valve opens letting the exhaust out to the exhaust system. This is super pressurized and loud as it rushes out, sort of like the car version of a loud fart, warranting the muffler on the exhaust system. As the piston moves up the cylinder, it chases out the remaining exhaust in preparation to start the whole thing over again.
This happens in each cylinder, each at a different time. This is the firing order. Firing order and timing are a whole other topic, but the Reader’s Digest version is:Each cylinder will have fired once to turn the crank shaft two times. So more cylinders, more “pushes” per turn. Not faster, but more oomph. This is what burns your gas, so fewer cylinders may mean better fuel economy, dependent on factors such as weight. Obviously, it takes more power to push an older car made of heavy steel than a car made of newer, lighter materials.

Blown Head Gasket
BLOWN HEAD GASKET JUNK CAR BUYER AUSTIN
A head gasket is a gasket that sits between the engine block and cylinder head(s) in an internal combustion engine.The gasket itself is a mechanical seal that prevents leaks between two things joined under compression by filling the space between them. It works similarly to a washer on a bolt. By preventing leaks, you ensure the best compression and you keep coolant from leaking into the engine. The head gasket in the engine has to take both hot and cold temperatures, back and forth, over and over. Cracks and leaks are bound to happen. The head gasket has a tough job and is the weakest link of the chain of parts that keep the combustion engine moving, so it’s more likely to fail than other parts.
If a head gasket leaks or blows, it’s usually not just one event that leads up to it. Either could happen during normal driving. The heat of the engine can gradually wear the gasket down with no major problems ever occurring. Until it leaks or blows, however, it’s hard to know if the head gasket is running out of time. It’s not something you can see looking at the engine; it’s way the heck in there and can’t be accessed without some major disassembly. Other things may signal your head gasket’s cry for help. You may see coolant leak from below the exhaust, you may be losing coolant with no visible leak or noticing bubbles in the radiator or coolant overflow tank. The engine may smoke (this will be white smoke; if not, keep looking because your engine has another problem), the exhaust may smell sweet or the oil may look like a rancid milkshake.
So what to do if you have a head gasket problem? It’s not a cheap repair. Let’s face it, this thing sits inside the engine. If it’s a minor leak, you may be able to seal it with products available like Blue Devil or K-Seal. Talk to a mechanic you trust to determine whether this will do the trick. Using these products could be as simple as pouring it in and letting it move through the works as you drive or may require a drain and flush of the cooling system—either option is far cheaper than replacing the gasket itself. Be forewarned that products like Blue Devil are meant to be permanent. Speaking from personal experience, once it’s sealed, there’s no going back or getting it out or working around it. That’s generally the idea, but sometimes folks look at it as a temporary patch.

The Dreaded Timing Belt
So you’re sitting in the waiting room, catching up on issues of magazines you would never order for yourself when your mechanic steps out from the mysterious back shop and says you need a new timing belt. You don’t know what this is but you know by the price he just quoted you, they’re definitely proud of it. You may not have noticed a problem. Perhaps you came in for something else. And you may have heard stories about shady shops recommending work you don’t need in an effort to add items to the bill. So do I really need one? Or does my mechanic’s kid need braces? Well, what is it and why? A timing belt is a rubber belt with teeth that goes along one side of your engine to keep the crank and camshafts timed properly.
In English, it’s part of a system that keeps the top half of the engine- cylinder head, valves- synchronized with the bottom half- crankcase, pistons (thanks for the simplification, Freddy “Tavarish” Hernandez). If you have a car that’s from the 90’s or before, you likely have a timing belt. Newer cars from certain manufacturers will have them still, but some have changed over to a timing chain which, in theory, lasts longer. Great, but I didn’t notice a problem. Why would I need a new one? You wouldn’t necessarily have any warning from the car if a timing belt is “going bad.” If it’s already broken, your car won’t start. If it’s on the way out, sometimes a squeak or an odd noise might give it away. If you were in for an oil change, a mysterious noise, or a service light from the dash, your mechanic may have noticed cracks on the belt or worn teeth that made him sound the alarm or he may be checking your mileage. Belt lifespan varies from model to model. At minimum, they’ll give you 60,000; some will double that and most will fall somewhere in between. Depending on your manufacturer recommendations, if you’re at 105,000 and you stare blankly at the tech when he asks if your belt has been changed, he’s likely going to recommend replacement. Even if you agree the belt needs to be changed, you have that dirty, four-letter word to contend with: COST. Parts are generally nothing special for this task, ranging from $150 to $250 in the most common models, even though certain models can be higher. What can often be misconstrued as fighting words is the labor cost. Also highly variable, labor could range from $170 to $600 or more.
The major factor is accessibility. To access the timing belt, you may be removing accessories, an engine timing cover, the water pump, pulleys, tensioners—no biggie if you have space to work under the hood but an unholy nightmare taking many labor hours if you’re poking around a V6 sedan with no easy access to inner parts. But that’s several hundred dollars I’m not prepared to part with yet. Do I really have to? No, the only things we have to do are pay taxes and die. Talk to your mechanic.
Cracks in the belt may not necessarily mean it’s bad. It could carry you a couple thousand more miles until you can sock away the cash. However, if your mechanic is particularly concerned for it’s condition, you may want to bite the bullet. No sense adding a tow bill and missing a morning of work to a project that’s already potentially costly.

Your exhaust produces harmful emissions of hydrocarbons, carbon monoxide and nitrogen oxides that are damaging to the atmosphere if released into the air.
A catalytic converter substantially reduces the amount of harmful pollutants by taking these gases and converting them into water vapor and less harmful gases via a series of chemical reactions. All gas cars manufactured since the early 1990’s requires having a catalytic converter fitted to the exhaust.
The catalytic converter includes a core of ceramics spotted with pores that measure less than 1mm. The pores are coated with powdered catalysts that contain metals such as platinum, palladium and rhodium. Because the pores are close to the engine they heat up and the chemical structure of the exhaust gases passing though it changes so that harmful gases that cause smog are removed and converted into nitrogen and oxygen. Converters are so efficient that the difference in emission readings for cars with converters and those without are considerable. The good news is that catalytic converters are expected to have a good life, but still need to be checked periodically for internal and external damage.
Catalytic converter issues can lead to increased exhaust emissions and a decrease in engine performance. Most issues stem from temperature changes in the exhaust system. Excessive unburnt fuel in the exhaust can cause the catalyst to reach extremely high temperatures which can cause damage to the fine catalyst material. (An engine that is performing at peak efficiency will burn all the fuel in the combustion chamber during the combustion process. An engine that is not performing properly, that is not burning all the fuel, will allow unburned or excess fuel to enter the exhaust system. When this excess or unburned fuel contacts the hot core of the converter it will ignite.) As a result, the catalytic converter becomes less effective, less chemical conversions take place and the exhaust output contains more harmful gases.
Similarly, rapid cooling of the catalytic converter, such as by being submerged in water, can cause the internal honeycomb structure to break apart and obstruct the exit to the exhaust pipe. If the catalytic converter becomes plugged, engine efficiency will decrease noticeably.
There are ways to keep your CAT Clean, remember that having a CAT on your car is a necessity and is a violation of the Clean Air Act not to have one, even off roading.
Keep your CAT clean and your environment beautiful!
