Air–fuel ratio (AFR) is the mass ratio of air to a solid, liquid, or gaseous fuel present in a combustion process. The combustion may take place in a controlled manner such as in an internal combustion engine or industrial furnace, or may result in an explosion (e.g., a dust explosion ).
An exhaust gas temperature gauge (EGT gauge or EGT sensor) is a meter used to monitor the exhaust gas temperature of an internal combustion engine in conjunction with a thermocouple-type pyrometer. EGT gauges are found in certain cars and aeroplanes. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR).
The basic operation of a feedback carburetor: The carburetor would take in a signal from the oxygen sensor and would determine if the mixture was correct; If the mixture needed to be adjusted, a solenoid or stepper motor would move to adjust the AFR; Most included electric chokes for cold starting
A carburetor (also spelled carburettor or carburetter) [1] [2] [3] is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. [4]
SECU-3 manages AFR on the carburetor engines (similar to AXTEC AFR systems), idle cut-off valve and wide open throttle mode valve in carburetor systems, controls electric fuel pump and gas valves in closed loop mode according to the feedback from the oxygen sensor. The SECU-3 system provides unique opportunities for reassigning the I/O pins of ...
Of the three types of carburetors used on large, high-performance aircraft engines manufactured in the United States during World War II, the Bendix-Stromberg pressure carburetor was the one most commonly found. The other two carburetor types were manufactured by Chandler Groves (later Holley Carburetor Company) and Chandler Evans Control ...
