Explanation:
Back pressure develops whenever the exhaust flow is restricted in the exhaust system. While some back pressure is advantageous, excessive back pressure lowers volumetric efficiency, which raises fuel consumption and decreases engine efficiency.
Explanation:
Exhaust gas recirculation (EGR) is a technique used to reduce NOx emissions, and the evaporation emission control (EVAP) system completely prevents fuel vapours from entering the atmosphere.
Explanation:
In addition to improving performance, insulation and shielding of the exhaust pipes will make the engine as a whole seem magnificent and stunning. Insulation ensures that heat is kept where it is needed and doesn't dissipate to harm other areas.
Explanation:
The most efficient method of lowering NOx emission is exhaust gas recirculation (EGR).
EGR involves channeling some exhaust flow back into the intake system, typically right after the throttle is opened.
As a result, the combustion chamber's temperature drops and NOx emissions decrease.
Explanation:
The most crucial external purification component placed in an automotive exhaust system is a three-way converter. It can oxidize and reduce hazardous gases like CO, carbon monoxide, HC hydrocarbons, and NOx nitrogen oxides released from vehicle exhaust. harmless nitrogen, water, and carbon dioxide.
Explanation:
Exhaust manifolds, which gather engine exhaust gas from several cylinders and transfer it to the exhaust pipe, are typically straightforward cast iron or stainless steel components.
