It’s a fact that natural gas vehicles produce less greenhouse gasses than either gasoline or diesel cars and trucks. But clean or no, some concerns have naturally been raised about a major shift to CNG. The most obvious one has to do with refueling. Most gas stations are equipped to gas up gas burning cars and trucks.Click to see full answer. Subsequently, one may also ask, are natural gas cars reliable? Natural Gas Cars: The Pros Both are fuel-efficient vehicles that burn low-emissions fuel that’s better for the environment than petroleum-based fuels. They aren’t expensive to build and don’t pose any danger greater than that of traditional gasoline vehicles. Here are the pros of driving a CNG car.Also Know, how do cars run on gas? A gasoline car typically uses a spark-ignited internal combustion engine, rather than the compression-ignited systems used in diesel vehicles. In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air. The air/fuel mixture is ignited by a spark from the spark plug. Secondly, are there cars that run on natural gas? Available production cars Existing gasoline-powered vehicles may be converted to run on CNG or LNG, and can be dedicated (running only on natural gas) or bi-fuel (running on either gasoline or natural gas). Until recently, the now-discontinued Honda Civic GX was the only NGV commercially available in the US market.Is natural gas better than gasoline?It’s cheaper than gasoline, that’s for sure. It is also a lot better on the emissions front and it has comparable engine efficiency rates to gasoline cars. What’s even better, natural gas is a safer fuel: it is lighter than air and dissipates in case of an accident, unlike liquid gasoline.
