Why does the 10th-generation Civic check the engine emission control system?
1 Answers
Here are the specific reasons why the 10th-generation Civic checks the engine emission control system: 1. Excessive carbon deposits in the intake system and at the root of the intake valves, causing the air-fuel mixture to be too lean during cold starts. 2. Severe throttle body contamination, leading to insufficient air intake. 3. The starter motor's speed does not meet the required specifications. Below are additional technical features of the 10th-generation Civic's engine: 1. 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 general gasoline engines, this innovative valve drive mechanism has the advantage of relatively lower friction torque, thus requiring less driving force. This effectively reduces engine power consumption and fuel consumption. 2. To significantly reduce the overall vehicle weight, the 1.4-liter gasoline engine uses an aluminum alloy cylinder block, achieving a notable lightweight effect. 3. Specially processed plastic intake manifolds replace traditional metal ones, not only achieving weight reduction but also effectively reducing intake manifold wall resistance, improving intake efficiency, and increasing engine power.
