How Electric Car Works

Electric cars are shown up in the news nowadays. The hybrid vehicles and especially the electric cars are talk of the town. The electric car is the best alternative for the petroleum cars. The reason for this includes many statements. The electric cars have a lot of advantages over the old fashioned petroleum cars. The popularity of the electric cars has reached almost all over the world. We are taught in schools about the alternative sources of energy. The alternative sources of energy are solar energy, gas energy, electrical energy, etc. The electric cars are the cars which can run on electricity. Actually the petroleum cars can also be converted into electric cars. It is very easy to convert a petroleum car into electric cars. Most of the petroleum cars are being converted into electrical cars as electrical cars is cost cutting.

It is almost not difficult to understand how an electric car works. The architecture of the electric car is quite different then the petroleum car. A electrical car is consist of lots of wiring. The electrical car has following main components:

Electric Motor
Motor Controller
Batteries

An electric car is powered by an electric motor while a petroleum car is powered by a petroleum engine. This is how an electric car defers from the petroleum car. Instead of a petroleum engine an electric motor is placed inside the electric car. The electric motor gets power from the controller. Number of rechargeable batteries provide power to the controller.

The controller gets the power from the batteries and gives it to the motor. The accelerator pedal is tied with a pair of potentiometers (variable resistors), which provides the signal for the controller how much power it is to to deliver.

The 300 volts dc current is inoput to the controller from the battery and  controller converts it into a maximum of 240 volts AC, three-phase, and  sends to the motor. Inside the controller there is a transistor which turns onand off rapidly. A connector connects these two potentiometers and the padal, when you push on the gas pedal, The controller gets information about how much power to deliver to the electric car’s motor from the potentionmeters. There are two potentiometers for the sake of safety. The controller checks the readings of the both potentiometers to be equal. If they are not, then the controller stops operating. When accsilator is pressed, the controller turns the switch on, and when it is removed, it would turn it off.

The batteries are the main sources of power for the electrical car. Number of rechargeable batteries provide power to the controller. The motor can use both AC and DC batteries. Batteries  run by chemicals such as lithiuem. You can recharge the batteries by just plugging in the wire to the electric socket.

In this article we discussed about the architecture and working of electrical cars. Hope that this information increased your knowledge about the electrical cars.

How Hybrid Car Works

Many people are now getting frustrated with their usual gas-guzzling conventional car because of the constant increase in fuel prices. Because of this, more and more people are looking for alternative modes of travel. Some people with cars are now leaving it on the garage and walks from home to work almost everyday to conserve fuel and some are taking the subways, and other transportation services that exist in order to save money.

However, there are some people who simply just need their car for their work. Because of this, many of this people are now considering selling their old conventional gas-guzzling cars and purchase a new kind of car that can cut fuel consumption by half. These new line of cars are called hybrid cars. Just imagine, you can effectively go more than 60 miles per gallon with hybrid cars.

Also, hybrid cars produce fewer pollutants than conventional cars. This means that not only will you cut fuel consumption by more than half, but you will also decrease the level of pollution that is poisoning the environment and people. With hybrid cars, everyone can benefit from it.

Now that you know about hybrid cars and is now considering to get one for your own, you now want to know how it works. You also want to know how it can relatively cut fuel consumption by half and you also want to know why it emits fewer pollutants than conventional cars.

First of all, you have to consider that hybrid cars can be quite expensive. However, when you compute the overall cost that you will spend on gasoline during the lifetime of the hybrid car and the conventional car, you will see that you will spend more money on conventional cars of the same weight class as the hybrid car with a higher retail price included and taxes.

Hybrid car buyers also enjoy tax incentives imposed by the government. So, when you purchase hybrid cars, you will enjoy tax breaks. Therefore, you will save more money.

The concept of the hybrid car is quite simple. Hybrid cars combine electricity, which is the cleanest energy source available, and internal combustion gasoline engine to run the car.

In simple words, hybrid cars utilize both electricity and gasoline energy to power the car. First of all, the hybrid car works when once you start the car and is in idle mode or not running, the gasoline engine is automatically shut off. This means that the car is purely running on electricity. This will explain why hybrid cars are very quiet. This will also explain why it can effectively conserve fuel consumption. Once you step on the accelerator, the internal combustion engine will automatically start up again. There are also hybrid cars that can run purely on electric mode. This is very useful if you are only using the car for local travels. You virtually don’t even need to put gasoline in the car.

However, in this type of hybrid car, you have to consider putting gasoline for long travels. You can even say that the gasoline will be used for back up power in case the battery is discharged. Most hybrid cars developed today don’t need to be plugged in like the electric car. The used kinetic energy when you are braking will be the one to recharge the battery.

This is how simple a hybrid car works. It will be comprised of a battery for energy storage, a generator, an internal combustion engine, a fuel tank, and an electric motor.

Now that you know how hybrid cars work, you now see how beneficial it can be if you are driving one. You will not only save a lot of money from fuel consumption, but you will also help save the environment by emitting far lower toxic fumes than conventional cars.

Green Tea Weight Loss: How it Works

Green tea weight loss has been the talk of the town recently. The brew’s beneficial health effects have been enticing more people to start including green tea in their daily diet. Here are the reasons why green tea is touted as the natural way to lose weight.

Green tea speeds up your metabolism.

A study has found that green tea extract helped increase energy expenditure, or enhancement in the body’s metabolism process. Researchers were able to conclude that green tea causes a boost in a person’s metabolic rate by 4 percent. The effects were considered to be a result of the activity of major green tea components called catechin polyphenols. These substances function by helping to improve the process of fat oxidation and thermogenesis, which refers to the rate at which the body burns calories. The increase of a person’s metabolic rate then causes a greater number of calories to be burned and body fat to be lowered, rendering green tea weight loss programs effective.

Green tea regulates glucose and slows down fat absorption.

Green tea has been found to be valuable in regulating the body’s glucose by slowing the rise in blood sugar, most especially after a meal. By acting as a glucose regulator, green tea prevents high insulin spikes, which leads to fat storage. Green tea also helps by slowing down the action of amylase, a certain digestive enzyme. The course involving the slowing down of amylase is essential in green tea weight loss as this helps stem the breakdown of starches or carbohydrates, which are the main causes why blood sugar levels rise after a meal. The catechins in green tea also help to suppress the passage of glucose into fat cells. The effectiveness of green tea weight loss programs are then made possible through glucose regulation and the repression of fat absorption.

Green tea weight loss programs can help cut down calories.

Compared to coffee, green tea is a more suitable drink for people who want their caffeine fix but don’t want the extra calories. Drinking coffee with calorie-loaded cream and sugar wreaks havoc on your waistline. Due to this, green tea weight loss programs advise against taking coffee to help cut back on calorie intake and eventually lose weight.

Green tea may help decrease the desire for food.

Animal studies done by scientists revealed that green tea can help lose up to 21 percent of body weight in rats. In the experiment, rats were injected daily with a green tea extract for seven days. The results showed that the rats lost their food cravings, which was evident in their food consumption that experienced a decrease of up to 60 percent. Researchers suggested that the reaction may have been caused by the way green tea regulates blood sugar.

With all these green tea weight loss benefits, people may wonder just how much green tea they have to take. Though answers vary, it’s generally considered that 3 to 5 cups of green tea day is most favorable. This amount can help burn an additional 70 calories a day.

Everything About Dieting: #1 How Dieting Works

Dieting is one of those things that is completely integrated into American culture. On any given day, a huge portion of the U.S. population is “on a diet” and “counting calories” in one way or another. And look at how many of the diet names in the following list you recognize: The Atkins Diet, The Cabbage Soup Diet, The Grapefruit Diet, The Hollywood Miracle Diet, The Rice Diet, The South Beach Diet…

You probably recognize many of these names because you hear them all the time!

In this article, we will look first at weight gain and why gaining weight is so easy. Then we will look at what you can do about weight gain—in the form of diet and exercise—to maintain a consistent weight.

Your Body’s Efficiency
Have you ever wondered why, for so many people (and especially for anyone older than 30 years old), weight gain seems to be a fact of life? It’s because the human body is way too efficient! It just does not take that much energy to maintain the human body at rest; and when exercising, the human body is amazingly frugal when it comes to turning food into motion.

At rest (for example, while sitting and watching television), the human body burns only about 12 calories per pound of body weight per day (26 calories per kilogram). That means that if you weigh 150 pounds (68 kg), your body uses only about:

150 X 12 = 1,800 calories per day

Twelve calories per pound per day is a rough estimate.
Those 1,800 calories are used to do everything you need to stay alive:

They keep your heart beating and lungs breathing. They keep your internal organs operating properly. They keep your brain running. They keep your body warm.

In motion, the human body also uses energy very efficiently. For example, a person running a marathon (26 miles or 42 km) burns only about 2,600 calories. In other words, you burn only about 100 calories per mile (about 62 calories per km) when you are running.

Interesting facts:
You can see just how efficient the human body is if you compare your body to a car. A typical car in the United States gets between 15 and 30 miles per gallon of gasoline (6 to 12 km/L). A gallon of gas contains about 31,000 calories. That means that if a human being could drink gasoline instead of eating hamburgers to take in calories, a human being could run 26 miles on about one-twelfth of a gallon of gas (0.3 L). In other words, a human being gets more than 300 miles per gallon (120 km/L)! If you put a human being on a bicycle to increase the efficiency, a human being can get well over 1,000 miles per gallon (more than 500 km/L)!

That level of efficiency is the main reason why it is so easy to gain weight, as we will see in the next section.

Re: How VTEC works

The DOHC i-VTEC system (one of the two cams shown). Found in the Honda/Acura K series, F20C and F22C1 engines, the i-VTEC system uses roller rockers, continuously variable intake cam timing (VTC, not shown) and three separate cam profiles for both the intake and exhaust valves of each cylinder. These features improve power and efficiency of the engine across its entire rpm range. Below 5800 rpm the offset and low lift of the valves aids in fuel atomization. This provides improved low end torque and fuel efficiency by creating a powerful swirl in the cylinder and by keeping the intake air charge at high velocity. Above 5800 rpm a high lift, long duration cam profile is engaged by the synchronizing pistons to provide greatly improved high rpm power and torque.
