Hybrid and green cars in the Philippines
Hybrid or green cars are motorized vehicles which use two or more power sources and fuel options to run. These vehicles use another source to power their movements other than the conventional fossil fuels like gasoline and diesel.
Other alternative power sources include electricity from a charged battery installed in the vehicle together with an electric motor, Liquified Petroleum Gasoline (LPG) which has been promoted as an alternative fuel and can be used via an LPG converter kit; and Petro-air whose engine uses a combination of compressed air and gasoline to power its cylinders with its "active chamber" doubling the energy output by heating the air in a designated compartment.
Relevance of Hybrid cars
The demand for hybrid or green cars arose because of a need for fuel efficient cars that produced less carbon emissions. These cars are known to be the automotive industry’s answer to the worsening greenhouse effect and global warming.
Car manufacturer’s have also included a separate line of models that are hybrid only- such as the Toyota Prius, which is known as the most sold hybrid-electric car in the world. Other car manufacturers prefer to simply include a hybrid version of an existing model such as the Ford Escape Hybrid and the Nissan Altima Hybrid. These vehicles are known as full or strong hybrids because they can run on a combination of power sources.
How do Hybrid cars work?
Aside from having a non-fuel power source that can be accessed together or separately with the fuel engine, hybrids have a different design than other regular cars that makes them fuel efficient and eco-friendly.
Some of the best characteristics of hybrids are that they are made of lighter materials making them weigh less; they have a different suspension or power distribution system, a smaller gasoline engine with fewer cylinders, low rolling resistance tires and advanced aerodynamics that reduce drag.
Power assist and mild Hybrids
Another classification of hybrids are known as “power assisted” which use their electric motor to improve the performance of their gasoline engine, such as the Honda Civic Hybrid and mild hybrids, which have starter motors that allow the engine to stop and restart quickly to save on fuel, like the Chevrolet Silverado Hybrid.
