What is the optimal tuning data for automotive gas?
2 Answers
For an 80-liter tank, the pressure is thirteen cubic meters. The following is a related introduction to automotive gas: 1. Types: Small vehicles mainly use CNG (Compressed Natural Gas), which has a short driving range and low gas consumption, with relatively low CNG tank costs; Large vehicles primarily use LNG (Liquefied Natural Gas), which offers a long driving range and high gas consumption, with higher LNG tank costs. 2. Properties: Gas supplied for automotive use must undergo processing. Generally, natural gas and liquefied petroleum gas supplied for civilian use contain many impurities. If used directly as automotive fuel, they can cause damage to vehicles. If the engine combustion is abnormal, it may also affect the vehicle's lifespan.
The optimal tuning data for automotive gas cannot be generalized, as it depends on your specific vehicle and fuel system. Common parameters like the air-fuel ratio should typically be adjusted between 14.5 to 15.0 to ensure complete combustion without being too lean or rich, which could affect power output. Ignition timing is also crucial—advancing it by a few degrees usually improves combustion efficiency and reduces waste. Pressure settings must remain stable within standard ranges; for example, CNG vehicles typically require around 200 bar, otherwise, the engine may experience vibrations or issues. Remember to dynamically adjust data based on engine load and RPM changes to achieve optimal performance. I recommend frequently checking diagnostic tool readings rather than guessing parameters to avoid problems during high-speed driving. In short, it's best to gradually calibrate using the vehicle manual and professional tuning tools—don't rush the process.
