Hypermiling
Hypermiling is driving or flying a vehicle with techniques that maximize fuel efficiency. Those who use these techniques are called "hypermilers". In the case of cars, this is an extreme form of energy-efficient driving. Hypermiling can be practiced in any vehicle regardless of fuel consumption. It gained popularity due to the rise in gasoline prices in the 2000s. Some hypermiling techniques are illegal in some countries because they are dangerous. In 2008, the ''New Oxford American Dictionary'' voted "hypermiling" the best new word of the year. Safety and awareness program Hypermiling has come under fire from several sides because some hypermilers show dangerous or illegal behaviour, such as tailgating larger vehicles on motorways to save fuel, cycling between accelerating and coasting in neutral, and even turning the engine off when its power is not needed. For this reason, the Hypermiling Safety Foundation was established in August 2008 to promote a safety and education program ...

Energy-efficient Driving
Energy-efficient driving techniques are used by drivers who wish to reduce their fuel consumption, and thus maximize fuel efficiency. The use of these techniques is called "hypermiling". Simple fuel-efficiency techniques can result in reduction in fuel consumption without resorting to radical fuel-saving techniques that can be unlawful and dangerous, such as tailgating larger vehicles. Techniques Maintenance Underinflated tires wear out faster and lose energy to rolling resistance because of tire deformation. The loss for a car is approximately 1.0 percent for every drop in pressure of all four tires. Improper wheel alignment and high engine oil kinematic viscosity also reduce fuel efficiency. Mass and improving aerodynamics Drivers can increase fuel efficiency by minimizing transported mass, i.e. the number of people or the amount of cargo, tools, and equipment carried in the vehicle. Removing common unnecessary accessories such as roof racks, brush guards, wind deflector ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fuel Efficiency
Fuel efficiency is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier (fuel) into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per application, and this spectrum of variance is often illustrated as a continuous energy profile. Non-transportation applications, such as industry, benefit from increased fuel efficiency, especially fossil fuel power plants or industries dealing with combustion, such as ammonia production during the Haber process. In the context of transport, fuel economy is the energy efficiency of a particular vehicle, given as a ratio of distance traveled per unit of fuel consumed. It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) ...

Tailgating
Tailgating is the action of a driver driving behind another vehicle while not leaving sufficient distance to stop without causing a collision if the vehicle in front stops suddenly. The safe distance for following another vehicle varies depending on various factors including vehicle speed, weather, visibility and other road conditions. Some jurisdictions may require a minimal gap of a specified distance or time interval. When following heavy vehicles or in less than ideal conditions (e.g. low light or rain), a longer distance is recommended. Causes There can be several reasons for tailgating. Preventing cut ins Tailgating can occur when a vehicle attempts to prevent another vehicle on the right or left from cutting in front of them. The tailgating (or preventing) vehicle will drive as close as possible to another leading vehicle to prevent the side vehicle from cutting in. Like all forms, this practice of tailgating is illegal and attempts to force the side vehicle to slow dow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

VariEze
The Rutan VariEze is a composite, canard aircraft designed by Burt Rutan. It is a high-performance homebuilt aircraft, hundreds of which have been constructed. The design later evolved into the Long-EZ and other, larger cabin canard aircraft. The VariEze is notable for popularizing the canard configuration and moldless glass cloth composite construction for homebuilt aircraft. Overview Work on the VariEze design, which grew out of Rutan's experience designing and building the VariViggen, began in 1974. The first prototype, designated Model 31 and registered N7EZ, first flew on May 21, 1975 after four months of construction. This aircraft used a Volkswagen engine conversion. Three months later it was shown at Oshkosh where Dick Rutan piloted it to an under 500 kg class distance record of . Rutan believed that by engaging in a program of breaking class records he could further fine-tune the design. The aircraft was so popular at Oshkosh that Rutan redesigned the airc ...

Fuel Economy In Automobiles
The fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. Consumption can be expressed in terms of volume of fuel to travel a distance, or the distance traveled per unit volume of fuel consumed. Since fuel consumption of vehicles is a significant factor in air pollution, and since importation of motor fuel can be a large part of a nation's foreign trade, many countries impose requirements for fuel economy. Different methods are used to approximate the actual performance of the vehicle. The energy in fuel is required to overcome various losses ( wind resistance, tire drag, and others) encountered while propelling the vehicle, and in providing power to vehicle systems such as ignition or air conditioning. Various strategies can be employed to reduce losses at each of the conversions between the chemical energy in the fuel and the kinetic energy of the vehicle. Driver behavior can affect fuel economy; maneuvers such as sudden acceler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rat Running
Rat running (also known as rodent running, cut-through driving, or dive-bombing) is the practice by motorists of using residential side streets or any unintended short cut such as a parking lot, delivery service lane or cemetery road instead of the intended main road in urban or suburban areas. Background Rat running is a tactic used to avoid heavy traffic and long delays at traffic signals or other obstacles, even where there are traffic calming measures to discourage its use or laws against taking certain routes. Rat runs are frequently taken by motorists familiar with the local geography. Rat running is controversial. When traffic is especially heavy on a highway or main road, rat-running vehicles may cause another traffic jam on the rat-run streets, along with accompanying problems such as collisions, pollution from exhaust, and road rage. It is sometimes opposed by residents on the affected streets, as they may regard it as a disturbance of their peace. Sometimes, it caus ...

Driving Techniques
Driving is the controlled operation and movement of a vehicle, including cars, motorcycles, trucks, buses, and bicycles. Permission to drive on public highways is granted based on a set of conditions being met and drivers are required to follow the established road and traffic laws in the location they are driving. The word driving, has etymology dating back to the 15th century and has developed as what driving has encompassed has changed from working animals in the 15th to automobiles in the 1800s. Driving skills have also developed since the 15th century with physical, mental and safety skills being required to drive. This evolution of the skills required to drive have been accompanied by the introduction of driving laws which relate to not only the driver but the driveability of a car. Etymology The origin of the term ''driver'', as recorded from the 15th century, refers to the occupation of driving working animals, especially pack horses or draft horses. The verb ' ' ...
