New CEC Gasoline Direct Injection Fuels Test - Comparison of Deposits and Spray Performance from New and Used Injectors 2019-28-2392
The use of deposit control additives in European market gasoline is well documented for maintaining high levels of engine cleanliness and subsequent sustained fuel and emissions performance. Co-ordinating European Council (CEC) industry fuels tests have played a crucial role in helping to drive market relevant, effective and low-cost deposit control additives into European market fuels. Until now, there hasn’t been a Gasoline Direct Injection engine test available to fuel marketers in any market globally. However, a new CEC engine test is currently being developed to address that gap. Based on an in-house VW injector coking test, it shows promise for becoming a useful tool with which to develop and measure the performance of deposit control additives. A key requirement of industry tests should be to replicate issues seen in consumer vehicles, thereby providing a platform for relevant solutions. For this paper, injectors from the new VW injector coking test in a clean and coked state were compared to injectors from vehicles in the market in respect of deposit geometry, elemental composition and injector spray performance.
