These can be battery or fuel powered but in either case, use less fuel, do no harm to the vehicle's engine, and reduce or eliminate emissions. [3] Other vehicles, including police, military, service trucks, news vans, fire trucks, ambulances, and hydraulic bucket trucks can be equipped with mobile power idle reduction systems, similar to a ...
This means that a bicycle will use between 10 and 25 times less energy per distance travelled than a personal car, depending on fuel source and size of the car. This figure does depend on the speed and mass of the rider: greater speeds give higher air drag and heavier riders consume more energy per unit distance. In addition, because bicycles ...
When gas prices soar, the Sentra's small fuel tank can make filling up less heartbreaking than larger cars with even bigger ones. Base price: $21,745 EPA combined/city/highway: 34/30/40 mpg
Fuel-saving devices are sold on the aftermarket with claims they may improve the fuel economy, the exhaust emissions, or optimize ignition, air flow, or fuel flow of automobiles in some way.

NOS may not be permitted for street or highway use, depending on local regulations. N 2 O use is permitted in certain classes of auto racing. Reliable operation of ...
To fuel a hydrogen car from water, electricity is used to generate hydrogen by electrolysis. The resulting hydrogen is an energy carrier that can power a car by reacting with oxygen from the air to create water, either through burning in a combustion engine or catalyzed to produce electricity in a fuel cell.
