Fuel pump
A fuel pump is a device that moves fuel from a vehicle's tank to its engine at the pressure and volume the fuel system requires.
Fuel tank
A fuel tank, also called a gas tank, is a container that safely stores fuel on board a vehicle or aircraft and supplies it to the engine.
Gasification
Gasification is a thermochemical process that converts carbon-containing materials like coal and biomass into syngas by reacting them at high temperature with controlled oxygen or steam.
Gasoline
Gasoline, also known as motor spirit, gasolene, or bensin, is a volatile hydrocarbon fuel refined from crude oil and blended with additives and ethanol, used mainly in vehicle engines.
Gasoline direct injection
Gasoline direct injection, also called petrol direct injection, is a fuel system for spark-ignition engines that injects fuel at high pressure directly into the combustion chamber.
Half-Heusler thermoelectric modules
A half-Heusler thermoelectric module is a solid-state generator converting heat into electricity via p-type and n-type half-Heusler alloy legs, suited to medium- and high-temperature waste heat recovery.
Heat engine
A heat engine, or thermal engine, is a device that converts heat from a hot source into mechanical work, rejecting the rest to a cold sink.
Heat of combustion
The heat of combustion, also called the heating value or calorific value, is the energy released when a unit amount of a substance burns completely in oxygen.
Hemispherical combustion chamber
A hemispherical combustion chamber, also called a Hemi-head, is a domed engine cylinder head chamber that allows large valves and short flame travel, used in Chrysler's Hemi V-8s from 1951.
High Sulphur Fuel Oil
High Sulphur Fuel Oil (HSFO) is a residual marine fuel with up to 3.5% sulfur, the dominant bunker fuel for ships until the IMO 2020 sulfur cap.
High-entropy oxide electrocatalysts for oxygen evolution
High-entropy oxide electrocatalysts for oxygen evolution are single-phase oxides containing five or more metals that catalyze the oxygen evolution reaction, an alternative to costly iridium and ruthenium catalysts.
History of gasoline
The history of gasoline runs from an 1860s waste byproduct of kerosene refining to the dominant US car fuel, shaped by cracking, leaded fuel, and regulation.
History of the internal combustion engine
The history of the internal combustion engine spans Étienne Lenoir's first commercial gas engine of 1860, Otto's four-stroke cycle of 1876, the Benz automobile, and Rudolf Diesel's 1897 engine.
Hydrothermal gasification
Hydrothermal gasification is a thermochemical conversion method that reacts wet biomass or organic waste in hot, pressurized water to produce gas rich in hydrogen or methane, with pilot plants only.
Hydrothermal liquefaction of plastics
Hydrothermal liquefaction of plastics (plastic HTL) is a thermochemical recycling process that decomposes waste polymers in hot, pressurized water into an oil refined into fuels and chemicals.
Hydrotreated vegetable oil
Hydrotreated vegetable oil (HVO), also known as renewable diesel or green diesel, is a liquid biofuel made by hydrogenating vegetable oils and waste fats, usable in diesel engines without modification.
Hyliion Holdings
Hyliion Holdings is a Texas-based power technology company founded by Thomas Healy in 2015 that builds the KARNO Power Module, a fuel-agnostic linear generator running on more than 20 fuels.
Hyundai Gamma engine
The Hyundai Gamma engine is a family of 1.4- and 1.6-liter four-cylinder petrol engines that Hyundai developed in 2006 for compact cars like the Accent and Elantra.
Ignition system
An ignition system is the assembly of components that initiates combustion in an internal combustion engine, using a high-voltage spark in petrol engines and compression ignition in diesels.
Ignition timing
Ignition timing is the crankshaft angle at which the spark plug fires in a spark-ignition engine, expressed in degrees before or after top dead center.
Induction generator
An induction generator, also called an asynchronous generator, is an induction machine that produces electricity when driven slightly above synchronous speed, commonly used for small hydro and wind energy.
Intercooler
An intercooler, also called a charge air cooler, is a heat exchanger that cools air compressed by a turbocharger or supercharger, raising air density so the engine makes more power.
Internal combustion engine
An internal combustion engine (ICE) is a heat engine in which fuel burns inside the engine, pushing a piston that rotates a crankshaft to produce mechanical work.
International Sustainability and Carbon Certification
International Sustainability and Carbon Certification (ISCC) is a certification system, operated by ISCC System GmbH, verifying sustainability and greenhouse gas performance of feedstocks and fuels through third-party audits.
Inverter model
An inverter model is a mathematical or simulation representation of a power inverter, used in power system engineering, with fidelity levels from switched models, through averaged circuits, to positive-sequence phasor models.
Jet A
Jet A is a kerosene-based jet fuel specified in ASTM D1655 and the grade most prevalent in the United States, with a freezing point of −40 °C.
Jet fuel
Jet fuel, also known as aviation turbine fuel or Jet A-1, is a kerosene-based petroleum product burned in aircraft gas turbine engines, with civil grades Jet A and Jet A-1.
JP-10 (fuel)
JP-10, or Jet Propellant-10, is a single-component high-energy-density hydrocarbon fuel made almost entirely of exo-tetrahydrodicyclopentadiene, developed by the US Air Force and Navy in 1978 for missiles.
JP-8
JP-8 (NATO designation F-34) is a kerosene-type jet fuel, essentially commercial Jet A-1 with additives, used by the United States military for aircraft and ground vehicles.
Kaplan turbine
The Kaplan turbine is an axial-flow water turbine with adjustable runner blades for low-head, high-flow hydropower, invented by Austrian engineer Viktor Kaplan and patented in 1913.
