Fuel efficiency is a form of thermal efficiency, which is the process of converting chemical potential energy contained in a carrier fuel into kinetic energy. Overall fuel efficiency varies per vehicle, and is understood as fuel economy in the context of transportation. In the United States, fuel efficiency is expressed in miles per gallon or mpg. Fuel efficiency is dependent upon many factors such as engine parameters, aerodynamic drag, as well as weight and rolling resistance.
Hybrid vehicles utilize two or more distinct power sources to propel the vehicle. Hybrid electric vehicles combine an internal combustion engine with one or more electric motors. Power for hybrid vehicles can be derived from many sources such as rechargeable energy storage systems, compressed air, electricity, radio waves, and liquefied natural gas.
Hydraulic and pneumatic hybrid vehicles use engines that charge a pressure accumulator to propel the wheels via hydraulic or pneumatic drive units. Hydraulic energy is understood as dealing with the mechanical properties of fluids. Hydraulic energy is utilized for the generation and transmission of power with the use of pressurized liquids. Pneumatic hybrid vehicles compress air using various devices such as reciprocating and axial-flow compressors, thereby aiding in mechanical motion.
The two most common ways to measure fuel usage in vehicles is by monitoring fuel consumption and fuel economy. Fuel consumption denotes the amount of fuel used per distance. Canadian laws allow for the use of either liters per 100 kilometers or miles per gallon. Fuel economy or efficiency is defined as output per distance travelled, or distance travelled per unit of fuel used. Car buyers can consult a Dodge Edmonton dealer if they have further questions about fuel consumption and economy.
An improvement in fuel economy for a relatively inefficient vehicle can provide greater financial savings and lessen environmental impact. This is most intuitively demonstrated using the inverse scale: gallons per mile or liters per kilometer. Car buyers should familiarize themselves with the mechanics that govern fuel economy and efficiency, which will aid them in selecting the best vehicles at Dodge Edmonton dealerships.
Some electronic devices have been marketed as fuel savers. Such devices can be plugged into a vehicle's cigarette lighter and display LEDs. It is claimed that such devices can maximize fuel economy up to 25 percent by power conditioning the vehicle's electrical systems. Car buyers should ask Dodge Edmonton dealerships about such devices.
