The World Gasoline Engine is a family of straight-4 piston engines, based on the Global Engine Alliance design. Three engines have been produced: a 1.8 L, a 2.0 L, and a 2.4 L. The initial design of the engine block and cylinder head was handled by Hyundai as part of the Global Engine Alliance. The engines feature an aluminum engine block with ...
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The majority of automotive four-cylinder engines use a straight-four layout [1] : pp. 13–16 (with the exceptions of the flat-four engines produced by Subaru and Porsche) [2] and the layout is ...
The inline-six engine (also referred to as a straight-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders.
The five most abundant greenhouse gases in Earth's atmosphere, listed in decreasing order of average global mole fraction, are: [5] [6] water vapor, carbon dioxide, methane, nitrous oxide, ozone. Other greenhouse gases of concern include chlorofluorocarbons (CFCs and HCFCs ), hydrofluorocarbons (HFCs), perfluorocarbons, SF6, and NF3.
A gas is a substance which (a) at 50 °C (122 °F) has a vapor pressure greater than 300 kPa (43.51 PSI) or (b) is completely gaseous at 20 °C (68 °F) at a standard pressure of 101.3 kPa (14.69 PSI). Gases are assigned to one of three divisions division 2.1 Flammable gas; division 2.2 Non flammable, Non-toxic gas; division 2.3 Toxic gas
The straight-five engine (also referred to as an inline-five engine; abbreviated I5 or L5) is a piston engine with five cylinders mounted in a straight line along the crankshaft . Although less common than straight-four engines and straight-six engines, straight-five engines have occasionally been used by automobile manufacturers since the late ...
RCP8.5 would result in the highest greenhouse gas concentration (measured as CO -equivalents). Representative Concentration Pathways ( RCP) are climate change scenarios to project future greenhouse gas concentrations. These pathways (or trajectories) describe future greenhouse gas concentrations (not emissions) and have been formally adopted by ...
The Balmer series is characterized by the electron transitioning from n ≥ 3 to n = 2, where n refers to the radial quantum number or principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 3 to n = 2 is called H-α, 4 to 2 is H-β, 5 to 2 is H-γ, and 6 to 2 is H-δ.
