HYBRID CARS

ABSTRACT

Have you pulled your car up to the gas pump lately and been shocked by the high price of gasoline? As the pump clicked past $20 or $30, maybe you thought about trading in that SUV for something that gets better mileage. Or maybe you're worried that your car is contributing to the greenhouse effect. Or maybe you just want to have the coolest car on the block.

The auto industry now has the technology that might answer all of these needs. It's the hybrid car. Any vehicle is a hybrid which combines two or more sources of power.(gasoline & electric power )

Increasing gas prices and higher levels of carbon dioxide, which contributes to the greenhouse effect, have led car manufacturers to create a new, more efficient car called a hybrid. A hybrid car is a gasoline and electric powered car. It uses both a gasoline engine powered by gasoline in a fuel tank and an electric motor powered by batteries.

We have collected information about the HYBRID CARS , which includes need of hybrid cars , advantages & disadvantages of hybrid cars, Maintenance ,mileage of hybrid cars and at the of the report we have also mentioned recent development of the hybrid cars.

INTRODUCTION

o What is a hybrid

Increasing gas prices and higher levels of carbon dioxide, which contributes to the greenhouse effect, have led car manufacturers to create a new, more efficient car called a hybrid. A hybrid car is a gasoline and electric powered car. It uses both a gasoline engine powered by gasoline in a fuel tank and an electric motor powered by batteries.

Gas powered cars have a fuel tank as the source of energy. Gasoline is supplied to the engine, which turns the transmission, turning the wheels. A tank of gasoline can fuel a car for about 300 miles, with a maximum of 100 hp, 8,000 RPM, and a speed of about 150 mph.

Electric cars use batteries to turn an electric motor. The motor then turns the transmission, which turns the wheels. An electric car can run for 50 to 100 miles on each charge, with a maximum of 15,000 rpm, 100 kilowatts of power, which gives it sports car like acceleration.

Gas and electric power can be combined in two ways to make a hybrid car. In a parallel hybrid, a fuel tank powers a gas engine and batteries power an electric motor, then both the motor and the engine turn the transmission, which turns the wheels. The engine is usually a small, 4-cylinder engine, making it more fuel efficient. The motor is also small. The fuel tank in a parallel hybrid usually has a 500 mile range. The batteries can store energy recovered from braking or generated by the motor. In a series hybrid, gasoline turns the generator. The generator then either charges the batteries or powers the electric motor, which then drives the transmission.
