How Well Do Hybrid Autos Perform

Introduction

It is said that, "hybrid" is product of elements of different nature. In the automotive sector this definition applies to hybrid engines that combine results from engine heat combustion with a conventional electric motor. The purpose of the application of hybrid engines in cars is to minimize the level of emissions and the consumption of fuel, without having to connect to a network power to recharge. This seems to be the bet and trend of car manufacturers. In the market today there are already several brands of builders who are adding some kind of hybrid engine in various prototypes and models of cars, among which may include the following: Audi Duo, Chrysler Citadel DYNALTO Citroën, Fiat Multiple Hybrid, Ford P2000 HEV, GM IMPACT ADVANCE SUW Mitsubishi, Renault and Volvo ECC VERT (Anderson & Anderson, 2010).

Discussion

The basic features of design of these cars with hybrid engines are incorporating small displacement engine and a body built in materials with optimized aerodynamics light to minimize the strength of the wind, and thus compensate for the weight of the batteries. The marketing of these hybrid cars aims to achieve a wide range of advantages over traditional cars, without causing substantial losses in both vehicle performance, such as autonomy and security. Hybrid vehicles are classified into two types: parallel, both the thermal and the electric motor can spin the wheels, and series, the internal combustion engine generates electricity and traction is provided by the electric motor only.

In the case of gas-electric hybrids, when the internal combustion engine works, what does with its maximum efficiency? If you generate more energy than necessary, the electric motor is used as a generator and charges the batteries of the system. In other situations, only the electric motor works by feeding on the energy stored in the battery. All electric cars use batteries charged by an external source, which causes them problems of autonomy of operation without recharging. Some may recover kinetic energy during braking (Bradley, 2002), which is usually dissipated as heat in the brakes, turning it into electricity. This type of brake is often called "regenerative".

The combination of a combustion engine always operating at peak efficiency, and the recovery of braking energy (useful especially in the city), makes these vehicles achieve better yields than conventional vehicles. All electric cars use batteries charged by an external source, which causes them problems of autonomy of operation without recharging. This prevents common complaint with hybrid cars.

The term hybrid drive is used to refer to vehicles with more than one source of propulsion. The systems can incorporate hybrid variety of energy storage and / or power converters. The objective of the development of hybrid technology is to combine two sources of energy; so that the qualities of each system to be used under conditions of generation variables, so that the overall benefits of hybrid system development outweigh the cost of ...
