Timing Advance Processor Factory introduces the reasons for the decline in car power after gas
(L) The nature of natural gas is stable and the burning speed is slower, so more ignition energy is needed to ignite it.
(2) The theoretical air-fuel ratio of a natural gas engine is 10:1. When the fuel enters the engine, natural gas occupies about 10% of the intake port volume, so the amount of air sucked into the engine is relatively reduced by about 10%, that is, the intake efficiency decreases. Causes the power of the engine to decrease.
(3) After the modification, the air-fuel ratio, ignition advance angle and other parameters have not been adjusted as necessary. Maintenance practice has proved that when the engine uses natural gas, the ignition timing should be appropriately advanced. As a countermeasure, when a car uses natural gas for a long time, it should be operated with gasoline for 10 minutes every month (preferably every week). The purpose is to prevent premature aging of the fuel supply system, deterioration of gasoline in the fuel tank, gelatinization, and increased moisture in the gasoline. It is recommended that natural gas vehicles use gasoline for continuous driving for more than 50km every 3000km, or use gasoline for cold start and warm-up every day.
