What are the two types of non-scheduled vehicle maintenance?
1 Answers
Non-scheduled vehicle maintenance is divided into break-in period maintenance and seasonal maintenance. China's vehicle maintenance system is classified into three categories: routine maintenance, scheduled maintenance, and non-scheduled maintenance. Scheduled maintenance is further divided into first-level, second-level, and third-level maintenance. More details about non-scheduled maintenance are as follows: 1. Vehicle break-in period: This refers to the initial mileage of a new vehicle or a vehicle after major repairs. During this initial usage phase, the friction surfaces of moving parts undergo mutual grinding, continuously improving fitting precision to smoothly transition to normal operating conditions. The service life, operational reliability, and fuel economy of a vehicle largely depend on the break-in process during its initial use. Therefore, the purpose of break-in period maintenance is to help the vehicle quickly adapt to various working conditions, significantly extend its service life, and reduce repair costs. 2. Seasonal maintenance: Changes in seasons and climate conditions inevitably affect vehicle operating conditions, impacting performance, service life, and fuel economy. To ensure reliable operation of vehicles in different regions and seasons, seasonal maintenance is performed before seasonal changes, combined with scheduled maintenance, to help vehicles smoothly adapt to regional and seasonal variations.
