Attention plug-in hybrid drivers
The fuel in the tank spoils
If you drive an electric hybrid engine almost exclusively to save costs and emissions, you may be in for a nasty surprise: The fuel in the tank spoils like milk forgotten in the refrigerator.
Each new technology creates unexpected problems. When the first fuel vehicles with partial hybrid electric (PHEV) and electric vehicles with gasoline engines appeared as power generators, engineers faced a new question: What if you were constantly driving with electricity from a battery and almost never needed a combustion engine? Mechanics want to work, otherwise they are at risk of damage.
This is one of the reasons why the combustion engine turns on from time to time, sometimes to fill a 12-volt battery. But now another problem appears: if the fuel is never used, it spoils like milk forgotten in the refrigerator. Gasoline ages in the tank – which we never noticed in the “normal” car because we use it. But that’s why the lawn mower won’t start after winter.
Gasoline does not like air
subordinate Mitsubishi Outlander PHEV About calls in German “Cars and Sports”, which addressed the topic, sometimes fills with 15 liters of fresh fuel when the combustion engine is rarely used. why? The specialist German magazine conducted interviews with experts. According to them, it takes from two months to a year for the hydrocarbons that manage to ignite during the cold start. There is also oxidation: gasoline becomes viscous and forms a kind of sludge that can clog lines, fuel pumps, and the like.
How fast depends on the conditions: the warmer the weather, the more empty the tank (that is, the more air the fuel can interact with), the faster – in tight and cold storage, gasoline will stay fresh for years. Therefore, you should keep the tank full if you drive a mostly electric hybrid electric vehicle.
Diesel life is faster
And diesel drivers are even worse off: diesel aging 2 times faster than gasoline, and then the “diesel plague” clogs everything. But this is rare with plug-in hybrids: Peugeot has had a diesel hybrid on occasion, and it is only currently combined mercedes diesel engine with plug.
