Exhaust gas analyzer of this sensor and to create smaller devices.Typical NDIR sensors cost in the (US) $100 to $1000 range. Used by older aircraft, the Cambridge Mixture Indicator displayed air-fuel ratio by measuring the thermal conductivity of exhaust gas. It was manufactured by the Cambridge Instrument Company. This device was installed on airplanes in the 1930s, including the Lockheed Model 10 Electra flown by Amelia Earhart on her last flight. Exhaust gas analyzer An exhaust gas analyser or exhaust CO analyser is an instrument for the measurement of carbon monoxide among other gases in the exhaust, caused by an incorrect combustion, the
Exhaust manifold the exhaust is allowed to flow freely. Exhaust manifold In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word "manifold" comes from the Old English word "manigfeald" (from the Anglo-Saxon "manig" [many] and "feald" [fold]) and refers to the folding together of multiple inputs and outputs (in contrast, an inlet or intake manifold "supplies" air "to" the cylinders). Exhaust manifolds are generally simple cast iron or stainless steel units which collect engine exhaust gas from multiple cylinders and deliver it to the exhaust pipe. For many engines, there are aftermarket tubular exhaust
