What are the available dual-fuel vans?

Currently, the available dual-fuel vans include Kia, Elysee, Emgrand EC718, JAC Bin Yue, Focus Hatchback 2.0 Manual Sport, and Dongfeng Fengshen S30 CNG. A dual-fuel vehicle, also known as a bi-fuel vehicle, is equipped with two fuel supply systems. One system supplies natural gas or liquefied petroleum gas (LPG), while the other supplies another type of fuel. These two systems deliver fuel to the combustion chamber in a predetermined ratio, where the fuels mix and burn inside the cylinder. Examples include diesel-compressed natural gas (CNG) dual-fuel vehicles and diesel-LPG dual-fuel vehicles. Characteristics of dual-fuel vehicles include significant savings in operating costs, minimal engine modifications required, no reduction in power output, and the ability to operate on either dual-fuel or the original pure diesel mode, ensuring high safety. Additionally, they offer lower emissions, extended engine lifespan, and reduced maintenance cycles. The downside is that due to the low energy density of gaseous fuels, natural gas vehicles carry less fuel, typically resulting in shorter driving ranges compared to gasoline vehicles. Furthermore, since gaseous fuels occupy a certain volume in the cylinder's combustible mixture (unlike liquid fuels in gasoline engines, whose volume is negligible), the same cylinder displacement yields less power when using natural gas as fuel.
I've been researching dual-fuel vans recently and found them quite suitable for families and small businesses. For example, I checked out the Wuling Rongguang Dual-Fuel version, which offers both gasoline and compressed natural gas modes. It saves a lot on fuel costs, especially for long-distance highway driving - with sufficient gas stations available, it can cut fuel expenses by half. Although the trunk space is a bit smaller, it's sufficient for daily necessities or small cargo. It's quite convenient for my family's daily use like picking up kids and deliveries, and it's also quieter than pure gasoline vehicles. When purchasing, pay attention to the distribution of gas stations - rural areas might have fewer options. I suggest first checking reviews from local car owner groups, don't just focus on the price, but also look into the actual failure rates.
I believe the highlights of bi-fuel vehicles (gasoline and natural gas) lie in cost savings and environmental friendliness. My family's van often runs on natural gas in urban areas, resulting in ultra-low expenses and reduced pollution emissions. Models like the Changan Honor dual-fuel are quite common in the market, providing sufficient power for both passenger and cargo transportation. However, it's important to note the higher maintenance frequency – I have to inspect the gas tank system every two months, as safety comes first. In the long run, these vehicles are suitable for friends with limited budgets or those engaged in delivery services. Just don't overlook the range issue; switching to gasoline as an emergency backup when out of gas works fine.
