Hydraulic Hybrid Vehicle for a Green and Clean Environment

In today's age, it is very essential to consider how we can keep our environment clean, green and pollution free. We need to find out the environmentally friendly options available to us and save and preserve our earth. One of the most popular reason for pollution is the transport. With so many vehicles running here and there on the roads, more smoke is emitted out from different corners. New technologies always try to find alternatives in place of hazardous new invention. That is the reason, the reputed auto makers of the world are coming up with the latest entrant in the automobile market, that is the hydraulic hybrid vehicle.

A hydraulic hybrid vehicle can make a lot of difference to the environment. This is the best alternative to a standard car. These vehicles cause no damage to the ozone layer. A hybrid vehicle uses power for functioning or movement from more than one source. Hydraulic hybrid cars use hydraulic technology or fluid power, along with gas or diesel. This is an additional source of power and a replacement for battery technology which is dangerous for the environment and also expensive and bulky. In hydraulic hybrid vehicles, the car's engine powers the hydraulic pump, which charges the accumulator of high pressure. This accumulator drives one or more pump motors which are connected to the wheels. There can be a single pump motor to drive a pair of wheels or one pump motor for each wheel. This depends on the design of the car. The hydraulic circuit is completed by the second accumulator of low pressure. The pump motors on the wheels reverse themselves while braking, and thus recharge the accumulator and capture the energy.

Hydraulic hybrid cars can not only keep the environment clean but also can also save money on fuel. When a hybrid car stops, it shuts off the gasoline engine at an instant. Such advantages have made hydraulic hybrid technology very popular and if everyone can afford to use a hydraulic hybrid car, the air will be a lot less polluted in a few years to come.

The US Environmental Protection Agency has been working on the designing and testing of hydraulic hybrid vehicles. A hydraulically driven UPS truck was displayed at the International Fluid Power Exposition in Las Vegas, stressing the need for using the fluid power as an alternative source of power.
