What are the reasons for the Civic's engine emission control system check?
1 Answers
The following are the specific reasons for the tenth-generation Civic's engine emission control system check: excessive carbon deposits in the intake system and at the base of the intake valves, causing the air-fuel mixture to be too lean during cold starts. Severe contamination of the throttle body leads to insufficient air intake. The starter motor's speed does not meet the required level. Below is additional information on the technical features of the tenth-generation Civic's engine: The engine's valve drive mechanism adopts a hydraulic support roller rocker arm structure. Compared to the commonly used hydraulic tappet valve drive mechanism in current gasoline engines, this innovative valve drive mechanism has the advantage of relatively lower friction torque, thus requiring less driving force, which effectively reduces engine power consumption and lowers fuel consumption. To effectively reduce the overall vehicle weight, the 1.4-liter gasoline engine uses an aluminum alloy cylinder block, achieving significant weight reduction. Special materials and specially processed plastic intake manifolds are used to replace traditional metal intake manifolds, not only achieving weight reduction but also effectively reducing intake manifold wall resistance, improving intake efficiency, and increasing engine power.
