61Supercharger — A supercharger is an air compressor used for forced induction of an internal combustion engine. The greater mass flow rate provides more oxygen to support combustion than would be available in a naturally aspirated engine, which allows more fuel… …
62Production–possibility frontier — In economics, a production–possibility frontier (PPF), sometimes called a production–possibility curve or product transformation curve, is a graph that compares the production rates of two commodities that use the same fixed total of the factors… …
63Coefficient of performance — The coefficient of performance or COP (sometimes CP), of a heat pump is the ratio of the change in heat at the output (the heat reservoir of interest) to the supplied work. Contents 1 Equation 2 Derivation 3 Improving COP 4 …
64Robust statistics — provides an alternative approach to classical statistical methods. The motivation is to produce estimators that are not unduly affected by small departures from model assumptions. Contents 1 Introduction 2 Examples of robust and non robust… …
65Carnot heat engine — A Carnot heat engine [In French, Carnot uses machine à feu , which Thurston translates as heat engine or steam engine . In a footnote, Carnot distinguishes the steam engine ( machine à vapeur ) from the heat engine in general. (Carnot, 1824, p. 5 …
66Turbocharger — A turbocharger, or turbo, is an air compressor used for forced induction of an internal combustion engine. Like a supercharger, the purpose of a turbocharger is to increase the mass of air entering the engine to create more power. However, a… …
67Production-possibility frontier — In economics, a production possibility frontier (PPF) or “transformation curve” is a graph that shows the different rates of production of two goods that an economy (or agent) could efficiently produce with limited productive resources. Points… …
68Productivity — in economics refers to measures of output from production processes, per unit of input. Labor productivity, for example, is typically measured as a ratio of output per labor hour, an input. Productivity may be conceived of as a measure of the… …
69Actual Grace — • A grace that is given for the performance of salutary acts and is present and disappears with the action itself Catholic Encyclopedia. Kevin Knight. 2006. Actual Grace Actual Grace …
70Fuel injection — Fuel rail connected to the injectors that are mounted just above the intake manifold on a four cylinder engine. Fuel injection …
