Abstract
A method and a system provide direct injection of an improver enriched fuel into an internal combustion engine of a motor vehicle. The method comprises providing a fuel with a fuel pump under a first pressure at a fuel inlet of an injector nozzle and providing a fuel improver with an improver pump under a second pressure at an inlet bore of the injector nozzle arranged downstream of the fuel inlet with respect to a nozzle outlet of the injector nozzle. The second pressure is higher than the first pressure at least for a limited time interval prior to injection to enrich the fuel with the fuel improver within the injector nozzle. The method also comprises injecting the improver enriched fuel into the internal combustion engine at the nozzle outlet.
