LNG – Liquefied Natural Gas

Posted by Krzysztof Lis on January 30, 2014

LNG, or liquified natural gas, is natural gas in a liquid state. It has been cooled to cryogenic temperatures, and because of that in atmospheric pressur it is in liquid state.

LNG can be used as car fuel, as well as CNG (compressed natural gas) can. Both these fuels have significant advantages over gasoline and diesel fuel.

Because of the liquid state, LNG is more than twice as dense as CNG. It needs to be stored in insulated tanks because of the low temperature, but under pretty low pressures, as compared to compressed natural gas. The latter requires over 200 times atmospheric pressure (3,000-3,600 psi, or 21 to 25 MPa), while LNG requires only 70-150 psi (0,5-1,0 MPa, 5-10 times the atmospheric pressure). LNG is supplied to the engine in liquid state and then vaporised, similarly to LPG (liquefied petroleum gas, propane-butane mix, also known as autogas).  WAIT! There is more to read… read on »

Diesel fuel / heating oil replacement

Posted by Krzysztof Lis on June 4, 2010

Many people want to know, whether it’s possible to replace heating oil with diesel fuel. In case heating oil in your tanks run out, is it possible to use diesel fuel instead?

Or the opposite question: is it possible to pour heating oil into your diesel truck fuel tank?

Let’s find out… WAIT! There is more to read… read on »

Diesel fuel – article from Wikipedia

I don’t want to repeat all the great information about diesel fuel that’s already published on Wikipedia, so instead I will just insert this article here. I will use this article as a reference in my future posts.

LPG – Liquefied Petroleum Gas – Autogas

Posted by Krzysztof Lis on July 1, 2008

Liquefied Petroleum Gas, abbreviated as LPG, is an internal combustion engine fuel, a mixture of propane and butane. It is an alternative to gasoline / petrol, in some countries it is very popular. In Poland, where I live, it’s very popular because it’s price is less than half of gasoline price! Because of that the cost of autogas (common name for LPG) conversion is returned pretty quick. WAIT!
