A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids.
A catalytic converter is an exhaust emission control device that converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves.
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.
A vehicle start-stop system or stop-start system automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions. This is most advantageous for vehicles which spend significant amounts of time waiting at traffic lights or frequently come to a stop in traffic jams. Start-stop technology may become more common with more stringent government fuel economy and emissions regulations. This feature is present in hybrid electric vehicles, but has also appeared in vehicles which lack a hybrid electric powertrain. For non-electric vehicles fuel economy gains from this technology are typically in the range of 3–10%, potentially as high as 12%. In the United States, idling wastes approximately 14.8 billion liters of gasoline per year.
The Honda Insight is a hybrid electric vehicle that is manufactured and marketed by Honda. Its first generation was a two-door, two passenger liftback (1999–2006) and in its second generation was a four-door, five passenger liftback (2009–2014). In its third generation, it became a four-door sedan (2018–2022). It was Honda's first model with Integrated Motor Assist system and the most fuel efficient gasoline-powered car available in the U.S. without plug-in capability — for the length of its production run.
The Ford Escape is a compact crossover SUV sold by Ford since 2000 over four generations. The first generation was jointly developed with Mazda which also created the Mazda Tribute and Mercury Mariner as the twin model. Second generations of the Ford Escape, Mercury Mariner, and Mazda Tribute were released in 2007 for the 2008 model year, but mostly restricted to North America. In other markets, the first generation models were either replaced by updated first generation versions, or replaced by the Mazda CX-7 (2006) and Ford Kuga (2008). Unlike the collaborative approach taken with the previous model, this time the design and engineering was carried out solely by Ford. Since 2013, the model has been paralleled with the Kuga sold outside North America, making them essentially identical. A hybrid option was again available.
The Mazda3 is a compact car manufactured by Mazda. It was first introduced in 2003 as a 2004 model, replacing the Familia/323/Protegé in the C-segment.
Homogeneous Charge Compression Ignition (HCCI) is a form of internal combustion in which well-mixed fuel and oxidizer are compressed to the point of auto-ignition. As in other forms of combustion, this exothermic reaction releases energy that can be transformed in an engine into work and heat.
Hydrogen fuel enhancement is the process of using a mixture of hydrogen and conventional hydrocarbon fuel in an internal combustion engine, typically in a car or truck, in an attempt to improve fuel economy, power output, emissions, or a combination thereof. Methods include hydrogen produced through an electrolysis, storing hydrogen on the vehicle as a second fuel, or reforming conventional fuel into hydrogen with a catalyst.
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 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 acceleration and heavy braking waste energy.
The Partnership for a New Generation of Vehicles was a co-operative research program between the US government and the three major domestic auto corporations that was aimed at bringing extremely fuel-efficient (up to 80 mpg‑US vehicles to market by 2003.
Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power.
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".
A hydrogen internal combustion engine vehicle (HICEV) is a type of hydrogen vehicle using an internal combustion engine. Hydrogen internal combustion engine vehicles are different from hydrogen fuel cell vehicles. Instead, the hydrogen internal combustion engine is simply a modified version of the traditional gasoline-powered internal combustion engine. The absence of carbon means that no CO2 is produced, which eliminates the main greenhouse gas emission of a conventional petroleum engine.
Honda Advanced Technology is part of Honda's long-standing research and development program focused on building new models for their automotive products and automotive-related technologies, with many of the advances pertaining to engine technology. Honda's research has led to practical solutions ranging from fuel-efficient vehicles and engines, to more sophisticated applications such as the humanoid robot, ASIMO, and the Honda HA-420 Honda-jet, a six-passenger business jet.
The Hyundai Blue-Will is a plug-in petrol-electric hybrid concept compact car designed by the South Korean car manufacturer Hyundai Motor Company. The vehicle was debuted at the 2009 Seoul Motor Show in South Korea.
The Mazda Kazamai is a concept car made by the Japanese car manufacturer Mazda. It was first introduced at the 2008 Moscow International Motor Show in August.
Skyactiv is a brand name for a series of automobile technologies developed by Mazda that increase fuel efficiency and engine output. The initial announcement of the Skyactiv technologies included new engines, transmissions, body, and chassis, which appeared in Mazda products from 2011 onwards.
An internal combustion engine is a heat engine in which the combustion of a fuel occurs with an oxidizer in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons, turbine blades, a rotor, or a nozzle. This force moves the component over a distance, transforming chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. This replaced the external combustion engine for applications where the weight or size of an engine were more important.
Nagare(流, flow) is an automotive design language created by Franz von Holzhausen and Laurens van den Acker for Mazda. Incorporated into a number of concept cars, starting with the car of the same name, the Nagare design lineup was intended as a showcase of what Mazda's cars may have looked like in 2020.
