LNG & Dual Fuel

How can we help?

LNG stands for ‘Liquefied Natural Gas’. LNG is used as a fuel for road transport and in marine and industrial applications.

Driving on LNG - LNG is an ideal fuel for heavy and long vehicles. The global consumption of LNG is growing rapidly and LNG plays an increasingly important role as a source of energy.


Compared to diesel and petrol, LNG is more environmentally friendly and cost effective.

Dual fuel

​Compressed Natural Gas, or CNG, and Liquefied Natural Gas, or LNG, are the same substance. CNG is received and stored a vehicle’s tank is gaseous form. To obtain LNG, natural gas is compressed and cooled to extremely low temperatures, at which point it turns to liquid. LNG can then be shipped, stored, and used to fill the tanks of LNG vehicles. Much of the global natural gas trade occurs in the form of LNG. Some countries, such as South Korea and Japan, receive almost all of the natural gas they use in LNG form.

In vehicle applications, the main advantage that LNG has over CNG is that it is more dense. For two tanks of the same size, the LNG tank will allow a vehicle to drive further than the CNG tank. This makes LNG an interesting option for heavy trucks traveling long distances.

The Diesel/Natural Gas Dual Fuel system is an innovative system for conversion of diesel engines on commercial and public transport vehicles into engines capable of running on a blend of diesel and natural gas.

The system’s sophisticated special electronics blend the two fuels, giving preference to use of natural gas with the economic benefits this brings.

The Diesel Dual Fuel Electronic Control Unit calculates in real time the amount of diesel fuel it can decrease and the amount to be injected, ensuring the same power output and fewer pollutants compared to the original engine, thus reducing consumption and running costs while retaining the same lifespan and performance of the original engine.


Autogas LNG

​When travelling with a natural gas fuelled car you save a lot on fuel costs: you will start saving as soon as you drive.

Natural gas is one of the cleanest energy sources: it has no unburned hydrocarbon emissions, which are considered hazardous and carcinogenic, and cuts CO2 emissions by 20%. This is why these vehicles are allowed on the road when others are not.

Prins natural gas systems permit conversion of all types of vehicles, with sequential, direct and conventional fuel injection.


  • Driving with natural gas ensures a significant reduction in both carbon dioxide emissions and the cost of traffic per kilometer. It is characteristic that the price of natural gas is much lower than that of gasolineabd diesel, ensuring rapid savings to anyone who uses it.
  • In environmental terms, the use of natural gas in auto motion achieves reduction in hydrocarbon emissions up to 80%, thus justifying its widespread use in developed and environmentally friendly countries.
  • As concerns the safety of the fuel, it should be emphasized that this is undeniable as auto-gas systems are of high standard and comply with the most stringent quality standards and control. Additionally, the safe operation of the gas is enhanced by the fact that it ignites only under exceptional circumstances (limited range of mixture with air).
