Air injection is a process that involves the introduction of air into an engine’s combustion chamber to increase the efficiency of the combustion process. This process helps to reduce emissions, increase fuel economy, and improve engine performance. In this article, we will explore the definition and meaning of air injection, its origin, associations, synonyms, antonyms, and example sentences.
Definitions
Air injection is a process that involves the introduction of air into an engine’s combustion chamber to improve the combustion process. The air is typically introduced through a secondary air injection system that is designed to reduce emissions and improve fuel economy. This process is commonly used in modern vehicles to meet emissions regulations.
Origin
The origin of air injection can be traced back to the 1960s when the first emissions regulations were introduced in the United States. These regulations required automakers to reduce the amount of pollutants emitted by their vehicles. Air injection was one of the solutions developed to meet these regulations.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, air injection is defined as “the introduction of air into the exhaust system of an internal combustion engine to promote more complete combustion of unburned hydrocarbons.”
The Oxford English Dictionary defines air injection as “the process of injecting air into the combustion chamber of an engine to improve the combustion process and reduce emissions.”
Associations
Air injection is often associated with emissions reduction and fuel economy improvement. It is also associated with modern engine technology and is commonly used in vehicles with advanced emissions control systems.
Synonyms
Some synonyms of air injection include air injection system, secondary air injection, and air injection pump.
Antonyms
Some antonyms of air injection include emissions increase, fuel inefficiency, and engine malfunction.
The same root words
Some words that have the same root as air injection include air intake, air filter, air pump, and air cleaner.
