Solutions for excessive HC emissions are: 1. Regularly use copper-based three-way catalyst cleaner to remove carbon deposits from the intake tract, combustion chamber, and the surface of the three-way catalytic converter, which can effectively reduce HC content in the exhaust. 2. Intake system malfunctions can also cause excessive HC emissions; repair the intake system. Additional Information: 1. Modern vehicle intake systems mainly consist of variable intake systems. 2. Variable intake systems are primarily divided into four types: VVT, CVVT, VVT-i, and i-VTEC. These four variable intake systems are the most commonly used in today's automotive market.
