It is expected that the number of vehicles with compressed natural gas (CNG) powertrain systems will continue to rise in the years to come.
The fuel-rails provide the CNG fuel with the required pressure from the pressure regulator up to the natural-gas injection valves.
The natural-gas injection valve injects natural gas (compressed natural gas – CNG) at system pressure into the intake manifold.
The electronic engine control unit is the central control unit and the heart of the engine management.
The distributor supplies LNG or CNG under stable pressure to all active injectors.
The high-pressure sensor measures the fuel pressure in the high-pressure fuel rail of engines with gasoline direct injection (GDI).
An alternative powertrain systems are helping to reduce emissions and operating costs.
Natural gas (compressed natural gas – CNG) stored under high pressure is supplied by way of the pressure regulator in the fuel rail.
The natural-gas injector injects natural gas (CNG, LNG) into the intake manifold at system pressure.
The LEGV meters gas into the intake manifold on the engine with extreme precision and ensures that the air and gas are mixed extremely well.
