What are the reasons for an LNG-powered vehicle not being able to accelerate?
1 Answers
There are several reasons why an LNG-powered vehicle may struggle to accelerate: 1. Increase the ignition advance angle: The main component of natural gas is methane, which has relatively stable chemical properties. Additionally, the ignition point of natural gas is higher than that of gasoline, and its flame propagation speed is slower. Therefore, even though natural gas has a high combustible component, it cannot be fully burned, leading to decreased power and fuel efficiency. Practical experience shows that increasing the ignition advance angle can help control power loss to a certain extent. Generally, the ignition advance angle should be increased by 12°-17° from the original vehicle setting. 2. Adopt high-energy ignition: Since the ignition point of natural gas is higher than that of gasoline and its flame propagation speed is slower, a stronger spark is needed to speed up flame propagation. Therefore, it is necessary to replace the original ignition coil with a higher-performance one to enhance the vehicle's power performance.
