Automotive Injection Pump
Cryostar is participating to the High pressure injection concept by developing and building a fuel pump
based on Canada-based Westport Innovations Inc.’s cryogenic technology used in the heavy duty automotive
market. The Cryostar LNG pump system is powered by the truck’s hydraulic system; it works like a
double-acting jack. The high-pressure side is similar to Cryostar’s standard pumps, but adapted to the
specific environment of the system. The pump has been designed especially for integration in the Westport
LNG tank.
Features of Westport HPDI:
● higher dual fuel engine efficiency
● use of cold rather than saturated LNG
● lower particles emissions
● diesel-cycle operation with approximately 95% replacement of diesel fuel
● single nozzle refueling
Peak Shaving Systems
Functional speed 20 50 cm
Functional pressure 318 Bar
Gas outlet T° -20 80 °C
LNG T° -162 °C
The peak shaving system allows storing and supply-
ing natural gas on demand in case of increasing gas
consumption, or lack of gas supply from the natural
gas grid.
These systems usually require very high flows, as well
as medium to high pressure.
Once the LNG is pressurized, it is sent to the vapor-
izers before being injected into the grid.
This system is composed by LNG storage tanks, high
pressure pumps, vaporization system, regulation system,
and is managed by the global plant control system
with remote access possibility.
