The trucks

Currently a number of major truck manufacturers are moving towards the standardization of natural gas powered trucks. These trucks often come from the factory to run on CNG. CNG and LNG combust in the same way in the motor, only the storage method and the supply to the motor is different.

The truck’s biggest advantages:
  • CLEAN Cleaner than Euro 6, without extra fittings like filters!
  • QUIET PIEK certified, 70% noise reduction relative to diesel!
  • SUSTAINABLE With liquified biogas, 80% CO2 neutral!
  • ECONOMICAL Savings on fuel costs of 2 to 3 cents per kilometre!
Iveco is currently the leader with regard to the technology for natural gas trucks producing 270-330 hp. Rolande LNG uses the Iveco Stralis as a demonstration truck to give transporters the chance to experience driving with this new fuel. This 270 hp truck has a range of over 1200km on one tank. The Iveco Stralis is CNG powered from the factory and is converted to LNG. The biggest modifications and differences are:

 

Fuel tanks

The fuel tanks (CHART) are round, vacuum insulated and are produced by a manufacturer with many years of experience with cryogenic materials and LNG. With the double-walled tank, the liquid is kept cold for as long as possible to delay warming and pressure build-up for as long as possible. A full tank can sit for over 10 days without problems before the pressure becomes too high and needs to be vented. With normal use of the truck, venting of the fuel is seldom to never necessary. As long as the truck continues to run regularly, the pressure will decrease sufficiently each time, avoiding the need for the tank to be vented. In the unexpected event of a situation in which the truck is out of use for a longer time, the Flair is installed for this. 

Heat exchanger:

The heat exchanger is an important component of the LNG/LBG truck. Because the motor needs to receive the gas at 7 bar for optimal combustion and performance, a heat exchanger and pressure regulator are used. The heat exchanger heats the cold gas, so that the liquid evaporates and becomes gaseous. The pressure regulator adjusts the pressure so that the motor is always supplied with the right amount of gas.
