The correct spelling of the term "induction manifold" is /ɪnˈdʌkʃən ˈmænɪfoʊld/. This term refers to a component in internal combustion engines responsible for evenly distributing air to all cylinders. The spelling of the first syllable "induction" reflects the "duh" sound that is represented by the letter "d." The second part, "manifold," is spelled with the "ow" sound, which is written as "o" in the phonetic transcription. Correct spelling of technical terms is essential for accurate communication in engineering and related industries.
The induction manifold is a component of an internal combustion engine that facilitates the flow of air and fuel mixture into the combustion chambers. It is an essential part of the engine's intake system, situated between the intake manifold and the cylinder head. The primary objective of the induction manifold is to distribute the air-fuel mixture evenly to each cylinder, ensuring optimal combustion efficiency and engine performance.
Typically made of metal, the induction manifold consists of a series of tubular passages designed to guide the mixture from the intake manifold to the intake ports of the cylinder head. It is strategically designed with various lengths, diameters, and shapes in order to enhance the velocity and turbulence of the mixture, promoting a more thorough fuel atomization.
The induction manifold undergoes a complex process known as induction, where it creates a pressure differential to draw in the air and fuel from the intake manifold. It utilizes engine vacuum, created by the downward stroke of the pistons, to pull the mixture into the combustion chambers.
In addition to its primary function of distributing the air-fuel mixture, the induction manifold also acts as a mounting point for various sensors and valves integral to the engine's control systems, such as the throttle position sensor and idle air control valve.
Overall, the induction manifold plays a crucial role in the proper functioning of an internal combustion engine by ensuring efficient delivery of the air-fuel mixture, which directly affects power output, fuel efficiency, and emissions performance.
The term "induction manifold" is derived from two different origins.
Firstly, the term "induction" comes from the Latin word "inductio", which means "bringing in" or "introduction". In the context of an engine, "induction" refers to the process of introducing air and fuel into the combustion chamber.
Secondly, the term "manifold" comes from the Old English word "manigfeald" which means "many" or "multiple". In engineering and mechanics, a manifold typically refers to a pipe or tube that connects multiple outlets or inlets.
Therefore, the term "induction manifold" is a compound term that combines the concept of "induction" with the functionality of a "manifold" to describe a component in an internal combustion engine responsible for distributing air and fuel mixture to the individual cylinders.
