The first Bosch natural-gas injection valve came onto the market years ago. The new NGI2 injector was specifically developed for the demands of automotive CNG injection. It features a series of technical innovations and serves as a benchmark for gas metering
The components through which gas flows are designed to cope with the high gas volumes and the high throughflow velocity.
Pressure losses before the throttling point and operating noise are kept to a minimum by a special flow guide.
The solenoid can be triggered by a standard driver stage, and its surface has been specially coated to prevent wear when used with oil-free gas.
With its special design, the NGI2 is far superior to all previously known gas-injection valves, and can be easily integrated in existing intake-manifold geometries.
