What Causes the Engine Emission Warning Light to Illuminate?
1 Answers
The illumination of the warning light is typically caused by poor fuel quality leading to damage of the oxygen sensor in the three-way catalytic system, poisoning of the catalytic converter, or malfunctions in the fuel pump or ignition system. Below is an introduction related to turbocharged engines: 1. Overview of Turbocharged Engines: A turbocharged engine refers to an engine equipped with a turbocharger. The turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It utilizes the inertial force of exhaust gases expelled by the engine to drive a turbine in the turbine chamber, which in turn drives a coaxial impeller. The impeller then pressurizes the air delivered through the air filter pipe, forcing it into the cylinders. 2. Function of Turbocharged Engines: The primary role of turbocharging is to enhance the engine's intake air volume via the turbocharger, thereby increasing the engine's output power and torque.
