Exhaust Gas Recirculation (EGR) is a nitrogen oxide emissions reduction technique used in internal combustion engines, where a portion of the engine's exhaust gas is recirculated back into the intake manifold to lower combustion temperatures. This process enhances fuel efficiency and reduces harmful emissions, contributing to compliance with environmental regulations.

nitrogen oxide emissions reduction

Internal combustion engines convert the chemical energy of fuel into mechanical energy through the process of combustion inside the engine's cylinders. They are widely used in various applications, including automobiles, aircraft, and industrial machinery, due to their efficiency and power output.

An intake manifold is a component in an internal combustion engine that distributes the air-fuel mixture to the engine's cylinders, optimizing air flow for efficient combustion. Its design significantly impacts engine performance, fuel efficiency, and emissions, making it crucial for both naturally aspirated and turbocharged engines.

Fuel efficiency refers to the ability of a vehicle or engine to convert fuel energy into kinetic energy, maximizing distance traveled or work done per unit of fuel consumed. It is a critical factor in reducing environmental impact, lowering fuel costs, and enhancing energy sustainability in transportation and machinery.

Environmental regulations are rules and standards set by governments or international bodies to protect the environment from harmful human activities. They aim to balance economic growth with the preservation of natural resources and ecosystems, often requiring businesses to adopt cleaner technologies and practices.
