The pros and cons of installing an ignition advance device in a gasoline-to-gas conversion are as follows: 1. Pros: The ignition advance device for natural gas fuel, due to its higher octane number and superior fuel performance compared to gasoline, can enhance engine performance by advancing the ignition timing. The installation of an ignition advance device increases engine power and torque while reducing energy consumption, thereby improving the power performance and fuel economy of dual-fuel vehicles to some extent. It also significantly addresses issues such as poor uphill acceleration performance and high gas consumption after the vehicle's gasoline-to-gas conversion. 2. Cons: Currently, the ignition advance device in engines is already optimized upon leaving the factory. Blindly installing such an ignition advance device may disrupt the engine's inherent ignition timing, leading to reduced engine power and operational vibrations in mild cases, and even engine knocking in severe scenarios.
Converting to CNG and installing an ignition advance device has its pros and cons. The benefits include improved engine efficiency—since natural gas burns slower, advancing the ignition allows for more complete combustion, saving fuel costs and significantly reducing monthly fuel expenses while also lowering emissions for better environmental friendliness. However, there are notable drawbacks: the installation cost is quite high, potentially costing several thousand yuan, and maintenance becomes more complex. If improperly adjusted, engine power may drop or overheating could damage components. Having done this modification myself, I initially saved a noticeable amount, but later required frequent maintenance to prevent malfunctions. I recommend seeking professional shops to avoid safety risks. Overall, while it saves money long-term, you should budget for repairs and avoid blindly following trends.
This thing is quite practical for money-savers. After installing the ignition advance device, my fuel costs dropped significantly—natural gas is cheap, saving a few cents per kilometer. The downside is the high initial installation and parts cost, plus you need to buy compatible equipment. Maintenance is also troublesome; sometimes the car feels sluggish or starts slowly, affecting daily commutes. Long-term cost savings are worthwhile, but you need extra budget for unexpected repairs. Regular circuit checks are recommended to ensure smooth operation—don't lose big for small gains. Before modifications, consult your insurer to confirm compliance, avoiding claim issues later.
