How Hybrids Cars Operate

October 2nd, 2009

A hybrid car’s engine and motor perform and operate differently depending on what type of driving you are doing. Your hybrid car will act differently in different situations. Sometimes the electric motor is operating; sometimes the gasoline engine and sometimes they are both working together. To get the best gas mileage you can; it is wise to understand how a hybrid vehicle works.

When you are at a full stop, such as a stop sign, usually the gas engine shuts off. This eliminates idling and reduces emissions. The electric motor is used to start the vehicle in motion when you push on the gas pedal. In cities and where there is a lot of stop and go traffic a hybrid vehicle can save you a lot of fuel.

When you are first starting off from a stop and when you are driving below 15 mph the electric motor runs the car by using its battery pack. The gas engine turns on and off as needed when you are driving your car. If you have a lead foot and floor the gas pedal when a light turns green you will not be saving as much on fuel. This is because heavy acceleration calls for extra power and causes the gas engine to start running.

During heavy acceleration usually the power comes from both the engine and the motor working together. During typical highway driving usually the vehicle is being powered by the gas engine. This is also when the gas engine is charging the electric motor battery pack.

The main reason why you never have to plug-in a hybrid car is because when you brake gently or coast you are actually charging the electric motor’s battery pack. The electrical motor acts like a generator to charge the battery pack.

Understanding how a hybrid vehicle works will help you to get the best fuel mileage and help clean up the environment.

Understanding Bio-diesel

September 26th, 2009

As more and more people are becoming aware that we need to do what we can to improve our environment. We have seen an increase in hybrid vehicles and alternative fuel is becoming more available. Bio-diesel is becoming a popular choice for substitution of petroleum fuels used in diesel engines.

Bio-diesel is the common name for fatty acid alkyl esters, which is a biological based fuel for diesel engines. It can be made from several different things including, animal fats, virgin vegetable oil or algae. It can also come from recycled oils from deep fryers used by restaurants.

Bio-diesel is eco-friendly and burns cleaner than fossil fuel. It also produces less carbon monoxide and soot than regular diesel fuel. On the other hand, it does release more nitrous oxide than regular diesel, which is a factor that causes smog.

Bio-diesel is what is referred to as a carbon neutral fuel. This means even though it releases carbon dioxide, it is the same type of carbon absorbed by plants or animal source it was produced from. Fossil fuels, which traditional diesel fuels are made from release carbon dioxide that could remain trapped below the earth’s surface instead of polluting the atmosphere.

Diesel engines also have the ability to run on straight vegetable oil or SVO. However modifications are required to the diesel engine. Vegetable oil is thicker than conventional fuel and needs to be heated before it can flow properly. A conversion system is needed to the heat the vegetable oil to the appropriate temperature before it can be burned in the engine.

Alternative fuels are the wave of the future. Everyday new technology and advances are being made to make more environmentally friendly fuels for vehicles. This means that as progress is made the availability will increase and the prices will decrease. This is good news for your pocket book and also good news for the environment.
