Accumulator The basic work register of a computer. Actuator A device which performs an action in response to an electrical signal. A D also ADC Analog-to-digital converter a device which is proportional to the analog voltage level input. Analog Circuits Electronic circuits which amplify reduce or otherwise alter a voltage signal which is a smooth or continuous copy of some physical quantity. Assembly Language An abbreviated computer language which humans can use to program computers. Assembly language eventually is converted to machine language so that a computer can understand it. BDC Bottom dead center the extreme lowest position of the piston during its stroke. Bit A binary digit the smallest piece of data a computer can manipulate. Block Diagram A system diagram which shows all of the major parts and their interconnections. BSCO Brake specific fuel consumption the ratio of the rate at which fuel is flowing into an engine to the brake horsepower being generated. BSHC Brake specific HC the ratio of the rate at which hydrocarbons leave the exhaust pipe to the brake horsepower. BSNOx Brake specific NOx the ratio of the rate at which oxides of nitrogen leave the exhaust pipe to the brake horsepower. Byte 8 bits dealt with together. CAFE Corporate-Average-Fuel-Economy. The government mandated fuel economy which is averaged over the production for a year for any given manufacturer. Capacitor An electronic device which stores charge. Catalytic Converter A device which enhances certain chemical reactions which help to reduce the levels of undesirable exhaust gases. Closed-Loop Fuel Control A mode where input air fuel ratio is controlled by metering the fuel response to the rich-lean indications from an exhaust gas oxygen sensor. CO Carbon monoxide an undesirable chemical combustion product due to imperfect combustion. Combinational Logic Logic circuits whose outputs depend only on the present logic inputs Combustion The .
