LNG is stored under extreme cold temperature -161 degrees in the tank. The tank contains two pressure relief valves with a mechanical and electronic shut-off valve. In addition, a number of safety provisions are integrated in the tank valve which provide safe storage of the LNG.

The fuel sensor is mounted in tank and based on the tank contents, it sends an electrical signal to the fuel switch with fuel level display. LEDs are used to inform the driver about the current fuel level. There is also an analogue gauge on the tank showing pressure

When LNG mode is selected, the shut-off valves will be activated. By activating the shut-off valves, LNG can flow to the pressure regulator. A filter is installed at the inlet of the pressure regulator, which filters the LNG. The pressure regulator will reduce the pressure and adjust it to a fixed differential pressure (delta pressure). To maintain a constant temperature and pressure, the regulator is connected to the engine coolant system. LNG is sequentially injected into the inlet manifold by the gas injectors. The filter unit is placed between reducer and injectors. It filters the LNG to prevent contamination of the gas injectors. A combined pressure/ temperature sensor is installed in the filter unit. This combined sensor measures the gas temperature and system pressure. There is also a MAP sensor placed in the intake manifold. The system pressure minus the intake manifold pressure (MAP) is the differential pressure (delta pressure) over the injector. These signals are processed by the Diesel Blend computer to obtain the proper mixture correction.

During cold start, the engine will run on diesel for a while, before switching to LNG. The switch-over time is calculated by the Diesel Blend computer and also depends on engine temperature.

The Diesel Blend system can be diagnosed by using the Diesel Blend diagnostic program. Any trouble codes present can be read and deleted. It is also possible to read-out parameters and program calibration parameters while calibrating the system.
