Disadvantages of China VI Diesel Vehicles?
1 Answers
Below are the disadvantages of China VI diesel vehicles: 1. Impact on normal vehicle operation; If the sulfur content is 10PPM, the passive regeneration time of the DPF is 100 hours per cycle. As the sulfur content increases, the passive regeneration time of the DPF will decrease. With reduced passive regeneration time, frequent stops for passive regeneration are required, which will inevitably lower the vehicle's operational efficiency. 2. Severely reduces the service life of the DPF: Leads to premature scrapping of the DPF, and the replacement cost for this part is also quite expensive, even reaching tens of thousands of yuan. Due to the high fuel quality requirements in the China VI phase, if post-processing issues arise due to substandard fuel quality, even during the warranty period, manufacturers may refuse warranty claims. Therefore, many OEMs require proof of fueling at regular gas stations for up to one year prior to the incident date during maintenance and warranty services.
