Does the Lavida have a particulate filter?
1 Answers
The 2021 Volkswagen Lavida 1.4T is equipped with a particulate filter, while the 1.5L version does not have one. The naturally aspirated 1.5L small-displacement engine meets environmental protection requirements, so it doesn't need a particulate filter. However, the 1.4T model doesn't meet the standards, hence the installation of the particulate filter. A particulate filter is a ceramic filter assembled in the diesel engine exhaust system, which can capture particles before they enter the air as chemical emissions. The particulate filter effectively reduces particulate emissions by first trapping the particles in the exhaust gas and then oxidizing the captured particles to regenerate the filter. During prolonged operation, the gradual accumulation of particles in the filter will increase engine backpressure, leading to reduced engine performance. Therefore, it's necessary to regularly remove the deposited particles to restore the filter's performance.
