What is the reason why a dual-fuel vehicle suddenly cannot switch to gas?
1 Answers
Conversion switch or the circuit controlling the conversion switch may have problems, and it needs to be repaired at a 4S shop. The following is a detailed introduction about dual-fuel vehicles: 1. Overview: A dual-fuel vehicle refers to a vehicle that uses both fuel and liquefied petroleum gas (LPG) as fuel, mainly existing in the taxi market. 2. Advantages: Stable combustion, no knocking, and convenient cold and hot starts. The storage, transportation, decompression, and combustion of compressed natural gas are carried out under strict sealing conditions, making leakage unlikely. In addition, the gas cylinders have undergone various special destructive tests, ensuring safety and reliability. Compressed natural gas burns safely, produces less carbon deposits, reduces vapor lock and knocking, which helps extend the service life of various engine components, reduces the number of maintenance and repairs, and significantly lowers maintenance costs. 3. Disadvantages: Due to the low energy density of gaseous fuels, natural gas vehicles carry less fuel and generally have a shorter driving range than gasoline vehicles. Since gaseous fuels occupy a certain volume in the combustible mixture in the cylinder (the volume occupied by liquid fuel in gasoline engine cylinders is negligible), the work done when using natural gas as fuel is less under the same cylinder working volume.
