Additional injection of fuel

On some versions of catalytic NOx converters additional injection of fuel can lead to NOx dogoraniye. It leads to that the main injection of fuel proceeds during 200 ° after VMT during a working step and a release step. Additional injection of fuel provides giving of a certain amount of fuel in fulfilled gases.

Unlike control and main injections injected fuel does not ignite, and in the form of steam takes away residual heat from the fulfilled gases. During a release step the mix of the fulfilled gases and fuel via final valves gets to system of production of the fulfilled gases. The part of fuel through system of a retsirkulyatsiya of the fulfilled EGR gases comes back to cylinders for a dogoraniye and brings besides to effect, as control injection of fuel. Catalytic NOx converters use fuel in the fulfilled gases as the actuation mechanism for reduction of the maintenance of NOx in the fulfilled gases.

As additional injection of fuel leads to dissolution of engine oil, such injection should be approved by the manufacturer of engines.
