What are the reasons for higher gas consumption after converting from gasoline to natural gas?

[VanEloise]

The reason for higher gas consumption after converting from gasoline to natural gas is that the ignition point of natural gas is relatively high, making it less easy to ignite compared to gasoline. Therefore, more gas is required to achieve successful ignition. Below is a detailed introduction about converting vehicles from gasoline to natural gas: 1. Overview: Natural gas burns noticeably slower than gasoline, which affects power output, and the starting performance will not be as ideal. Consequently, another direct issue is that the engine power of the vehicle will decrease after the conversion, typically by around 15%. 2. Others: The compressed natural gas (CNG) used in vehicles is in a gaseous state, even though it is under pressure. However, compared to the volume change of gasoline, it is relatively much smaller. In the special energy conversion mechanism of an internal combustion engine, the expansion and work efficiency of natural gas is far inferior to that of gasoline. Thus, despite the high calorific value of natural gas, it can instead bring about side effects.
