Market full of oil, price trend "fake": Ahmadinejad

By Hashem Kalentari Tue Jun 17, 2:59 AM ET

ISFAHAN, Iran (Reuters) - The market is full of oil and the rising price trend is "fake and imposed," Iran's president said on Tuesday, partly blaming a weak U.S. dollar which he said was being pushed lower on purpose.

"At a time when the growth of consumption is lower than the growth of production and the market is full of oil, prices are rising and this trend is completely fake and imposed," President Mahmoud Ahmadinejad said in a televised speech.

"It is very clear that visible and invisible hands are controlling prices in a fake way with political and economic aims," he said when opening a meeting of the OPEC Fund for International Development in the central Iranian city of Isfahan.

Iran, the world's fourth-largest oil exporter, has repeatedly said the market is well-supplied with crude and blames rising prices on speculation, a weak U.S. currency and geopolitical factors.

"As you know the decrease in the dollar's value and the increase in energy prices are two sides of the same coin which are being introduced as factors behind the recent instability," Ahmadinejad said.

Oil steadied on Tuesday after touching a record near $140 the previous day, with traders caught between a weaker dollar and expectations that top exporter Saudi Arabia will ramp up output to its highest rate in decades.

Iran has often said it sees no need for the Organization of the Petroleum Exporting Countries (OPEC) to boost output.

"EVER-INCREASING DECREASE"

Ahmadinejad reiterated his view that oil should be sold in a basket of currencies rather than U.S. dollars, an idea which has failed to win over other OPEC members, except Venezuela.

"The ever-increasing decrease in the dollar's value is one of the world's major problems," he said.

"A combination of the world's valid currencies should become a basis for oil transactions or (OPEC) member countries should determine a new currency for oil transactions," he said.

Iran, embroiled in a standoff with the West over its nuclear program, has for more than two years been increasing its sales of oil for currencies other than the dollar, saying the weak U.S. currency is eroding its purchasing power.

Ahmadinejad, who in the past has called the dollar a "worthless piece of paper," suggested "some big powers" were driving it lower on purpose:

"The planners for some big powers are acting to decrease the dollar's value," he said. "For years they imposed inflation and their own economic problems to other nations by injecting the dollar without any support to the global economy."

Foes since Iran's 1979 Islamic revolution, Tehran and Washington are also at odds over Tehran's disputed nuclear activities as well as over policy in Iraq. Iran says its atomic work is peaceful.

Cooling fan Relay always faulty


Another problem arise, This happen so many times, The relay cooling fan hot and brunt, so i have to scratch the burnt place and connect it back to the connector base. It ok for a while 4-5 weeks then burn again. SO i change the relay. then burnt again. I don't know what is the real problem. Is that the wiring or the relay or the lose connector or the cooling fan itself? Things that i've done change the relay and tghtimg the connection between the base connector and the relay. 2 is left the wiring and the cooling fan not changed yet. I found this Q&A, I think this would help.

Question: 1999 Ford Taurus V6 3.0 mileage: 65,000. When I put the air-conditioner on it works fine until the condenser heats up at which time the clutch slips. The problem is that the fan under the hood does not come on when the air is turned on. What activates this fan to come on when the air is turned on?

Answer: First, check for 12-volts to the fan motor when the air-conditioning is on. Also, check the wiring for damage and poor ground connections. The fan is controlled by an integrated controller. You may need a cooling fan motor.

May be I will try select this option :- change the cooling fan.

Oxygen Sensor -How does it Works?


This is eg. of the burnt O2 sensor.

Every new car, and most cars produced after 1980, have an oxygen sensor. The sensor is part of the emissions control system and feeds data to the engine management computer. The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible.



A gasoline engine burns gasoline in the presence of oxygen (see How Car Engines Work for complete details). It turns out that there is a particular ratio of air and gasoline that is "perfect," and that ratio is 14.7:1 (different fuels have different perfect ratios -- the ratio depends on the amount of hydrogen and carbon found in a given amount of fuel). If there is less air than this perfect ratio, then there will be fuel left over after combustion. This is called a rich mixture. Rich mixtures are bad because the unburned fuel creates pollution. If there is more air than this perfect ratio, then there is excess oxygen. This is called a lean mixture. A lean mixture tends to produce more nitrogen-oxide pollutants, and, in some cases, it can cause poor performance and even engine damage.

The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The mechanism in most sensors involves a chemical reaction that generates a voltage. The engine's computer looks at the voltage to determine if the mixture is rich or lean, and adjusts the amount of fuel entering the engine accordingly.

The reason why the engine needs the oxygen sensor is because the amount of oxygen that the engine can pull in depends on all sorts of things, such as the altitude, the temperature of the air, the temperature of the engine, the barometric pressure, the load on the engine, etc.

When the oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing. Your car performs poorly and uses more fuel than it needs to.

Why 'Fuel Saver' in your car supposedly 'save th fuel' don't make any differencee?

Newly car always have computer controlled engine which include of O2 sensors, fuel injection system and so on integrated and calculated to produce the efficiency of the engine, how much fuel to the sparkplug and so on. In some car it called ECU

Fuel saver try to save your fuel consumption, for example the hyrogen producing fuel saver that inject hidrogen+oxygen the the air intake and mix with the petrol to make more combustible engine which in turn make fuel lesser for longer distance. Saves fuel. Less fuel more kilometers.

In my opinion and from what i've read. The ECU or computer seeing this phenomena differently. Whenever external substances added and make the engine leaner with less fuel, the computer keep trying to correct the situation by adding more fuel to make engine idle to at the previous state. Because the computer sees this situation as abnormal and try to correct it. So instead of it saves fuel now it consume more fuel.

So after a long time many claims that the fuel saver don't works anymore. It just funtion well at the beginning, it smoothes the engine when idle for example. it saves fuel but now back to previus state.

After reading some articles in internet, There is a guy which uses the HHO technique as fuel saver. He also introduce a method/technique to fools the O2 sensor. The method is to send the false signal to the O2 sensor that eventhough the hho gas injected to the combustion chamber the engine is fine no demand for more fuel, the engine is normal. So by this way the 'fuel saver works. It saves gas.

The method is to troduce simple electronic circuit to the O2 sensor in the middle before it reach to the ECU/computer box.

More info:


EFIE Circuit


In the past, fuel savers would not work when applied to fuel systems with oxygen sensor feedback circuits. These systems were designed to prevent efficient combustion!

Modern fuel systems use an oxygen sensor to maintain a constant air-fuel ratio of the engine. Increasing the combustion efficiency of the engine increases the percentage of oxygen in the exhaust because the engine uses less fuel for the same volume of air and more oxygen is free because the engine produces less carbon monoxide and oxides of Nitrogen.

The increased oxygen content in the exhaust is read by the computer to be a lean mixture in the engine. As a result, the computer then adds extra fuel to bring the pollution back to normal. In other words, when the computer sees extra oxygen in the exhaust, it sends enough fuel to maintain a 14.7 parts air to 1 part fuel ratio. When the computer sees less oxygen in the exhaust, it backs off on the fuel to maintain a 14.7 to 1 fuel ratio. The EFIE's function is to modify the oxygen sensor's output-signal by adding a floating voltage; so the computer will not see the extra oxygen and fight your fuel saver by adding extra fuel.

May this info might help.

Why My Radiator Water Keeps Dropping?

There are several reasons of engine cooling system failure.

Common Engine Cooling Problems:

Let's look at the common problems cars have with the cooling system.

Broken tubing. Hoses and tubing wear out and leak coolant fluid. Once the coolant has left the system it can no longer cool the engine and therefore the engine will over heat.


Broken fan belt. The water pump is driven by the engine through a fan belt. If this belt breaks the water pump can not turn and coolant will not be pushed through the car engine. This will also lead to the engine overheating.


Damaged radiator cap. The radiator cap is designed to hold a certain pressure in the coolant system. Most caps hold 8 - 12 PSI. This pressure raises the point in which the coolant will boil and maintains a good, stable system. If your cap does not hold enough pressure, then the car engine could overheat on hot days since the system never becomes pressurised.


Water pump failure. Most commonly you will hear a horrible screeching noise and will be able to see engine coolant leaking from the front of the pump or underneath the car. Often there are early signs of trouble with small spots of coolant under the car after being parked overnight and a strong coolant odor whilst you are driving.


Head gasket. Do you have large amounts of white smoke flowing out of your exhaust? Then you could have a problem with your head gasket. The head gasket seals the cylinder head to the engine block and also seals the coolant passages. When this gasket fails coolant can enter the cylinder and it will be turned to vapor as the engine fires. Head gaskets most often fail after the engine has overheated in the past. When very hot, the cylinder head can warp and prevent the engine head gasket from sealing properly.

My car have water radiator level keep falling after a 3-4 day drive. And need to top up after 3-4 days. In the past i have car breakdown due to cooling fan malfunction. So engine become overheating and make me to stop the car in the middle of the road. After repaired (cooling fan replaced) the water level of my radiator keep falling after few days. I have checked no water leakage and my mechanics also found no leakage.

I think the head gasket is the problem as it suit what happen to my car in the past. And I never replaced the head gasket yet.

Energy Crisis - Alternative Source?

These days increases fuel price almost inevitable. Is there any possiblities the price of gasoline fall to 50 usd per barrel? Look now it the trend is going up? from 100 now far away reaching to 200 per barrel. What is next year what is the price 5 years or 10 years from now?

It is time to change. We must explore alternative sources of energy. The Alternative souces will be multiple source. We can't hardly depends on one source as now we depends on oil. I believe no single alternative energy can replace oil. As oil can be produce by mass production in a day depends on in availability and volume at the oil producing countries. So we need multiple sources energy to replace oil to cover our energy demands or need.

What are the alternative energy sources? There are several to name.
1. Solar energy
2. Wind Power
3. Hydro electric
4. Hidrogen fuel cell
5. Geothermal
6. Tides
7. Biofuel or biodiesel to replace diesel
8. etc

What is Inflation?

Question: What is Inflation?

Answer: To understand inflation, we first must understand what the word means. The Economics Glossary defines Inflation as:

Inflation is an increase in the price of a basket of goods and services that is representative of the economy as a whole.

A similar definition of inflation can be found in Economics by Parkin and Bade:

Inflation is an upward movement in the average level of prices. Its opposite is deflation, a downward movement in the average level of prices. The boundary between inflation and deflation is price stability.

Why Inflation happen?

inflation is caused by a combination of four factors:

1. The supply of money goes up.
2. The supply of other goods goes down.
3. Demand for money goes down.
4. Demand for other goods goes up.

How to control inflation especially individually, you must cut expenses, cut cost, budget your expenses, that helps you save more money than before. But how to overcome the infaltion?

To control and overcome the inflation is 2 different thing. To overcome inflation your must be wealthy. In other word you must much more richer than you are now. When you are rich you don't care much if the price of petrol goes up. Or the grocery prices go up. You still have much money.
So you don't care much about prices because you can afford them, not a burden anymore.

Harga Minyak Malaysia naik?

Elaun menteri2 patut kena potong juga, sbb duit yang bayar elaun menteri tu pun duit rakyat juga. rakyat tanggung susah cakap kita sama2 berjimat cermat, padahal menteri2 tak rasa apa pun sbb dapat elaun itu dan ini, gaji pun besar. Duit elaun rakyat yang bayar. Rakyat makin kedana.

Bukan kata potong duit elaun tu boleh buat bayar subsidi minyak negara. Memanglah tak logik, tapi supaya menteri2 dapat merasa kenaikan harga minyak ni dgn nyata. Berat sama dipikul ringan sama di jinjing. Kata nak sama2 berjimat cermat so rasalah sendiri harga minyak yang lebih rendah berbanding negara2 lain ni, terutama negara2 miskin. Tak bandingkan dgn Negara Brunai ke?

So sekarang ni macam mana Pak Lah? Pakai cara apa nak tangani harga minyak ni? Ada Plan mesra rakyat tak? Harga minyak ikut harga pasaran dgn 30sen je subsidi? Kalau minyak naik lagi 150usd setong? 170 usd setong? mcm mana? tak cukup rasanya dgn rm 2.70 sen seliter mesti kena naik lagi. 3 ringgit ke 4 ringgit ke seliter tak gitu?

Harga minyak nak turun? Skrg ni harga minyak tgh naik. OPEC tak nak tingkatkan pengeluaran minyak sbb dia cakap bekalan minyak dunia mencukupi, harga sekarang adalah harga spekulasi contohnya sbb ketegangan di asia barat, permintaan tinggi negara Cina dgn India, dan yg baru2 ni ancaman Israel nak serang Iran terun harga minyak melonjak naik. Betul juga .. harga spekulasi. tapi masalah nya harga minyak tak turun tapi terus menaik. OPEC pun terus berkeras.

Mungkin juga nilai dollar yg semakin menyusut. Nilai dollar yg semakin menyusut membuatkan harga minyak semakin mahal. Kuasa beli US semakin rendah dan lemah sbb harga dah jadi mahal. Nilai dollar utk beli setong minyak makin mahal. Penyusutan dollar di sebabkan oleh krisis subprima yg berlarutan dan sebagainya. Tapi USA berusaha utk menyorok kelemahan sendiri dgn menyatakan sbb yg lain kenaikan harga minyak. Seboleh2nya tidak mengaitkan dgn kelembapan ekonomi US.

So harga minyak Malaysia nak naik lagi la ni, bukannya setakat 2.70 sen tapi terus manaik tak gitu?
