“…A 4.6% Injector 3: B10 biodiesel 3.6% Figure 10 shows the analysis of the composition of the deposits for the three injectors [20]. The figure shows that zinc accounted for up to 31% of the deposits in injector number 1, up to 25% of deposits in injector number 2 and significant lower content in injector 3.…”

“…The second engine was the turbocharged Ford Puma engine which used a conventional, distributor pump injection system. It was claimed that "this system is extremely close to a common-rail system without actually being one" [20]. The test cycle was also developed by the CEC but this cycle requires zinc added to the fuel to produce deposits and the engine is not representative for the current market.…”

“…In reference [20] the influence of zinc on the mechanism for the creation of deposits was investigated through an analysis of the injector deposits at the end of the test. It was reasoned that with the use of zinc, a "possible mechanism is that zinc is acting as an accelerant or catalyst for the normal deposit processes and would exaggerate the normal mechanism of injector fouling."…”

Current developments in fuels and emissions regulations are resulting in increasingly severe operating environment for the injection system. Formation of deposits within the holes of the injector nozzle or on the outside of the injector tip may have an adverse effect on overall system performance. This paper provides a critical review of the current understanding of the main factors affecting deposit formation.Two main types of engine test cycles, which attempt to simulate field conditions, are described in the literature. The first type involves cycling between high and low load. The second involves steady state operation at constant speed either at medium or high load.
