A common method of reducing pollutant emissions in modern internal combustion engines while increasing efficiency is to inject the fuel directly into the combustion chamber. Direct injection requires that the respective injector (gasoline or diesel) has access to the combustion chamber.

As a result, the sensitive nozzle head permanently comes into contact with exhaust gases (including soot). Depending on the driving style and fuel quality, deposits quickly form at the fuel outlets on the nozzle head. The injected fuel can therefore no longer mix optimally with the air, which in turn leads to higher consumption and an associated increase in pollutant emissions. As time goes on, more combustion residues such as soot are produced, clogging the fine outlets even more.

This leads to even worse combustion, right up to blocking of the injector or failure of the system, which can entail costly repairs. Another problem with direct-injection gasoline and diesel engines is that the intake area is not cleaned. On the one hand, this is contaminated by the exhaust gas flowing back at the valve overlap or by the crankcase ventilation (deposits on the intake valves), and on the other hand by the exhaust gas recirculation system. This combination of exhaust gas tract and intake tract causes what can be enormous deposits on the intake side of the engine. The resulting problems are varied – from a completely contaminated intake area, through a defective exhaust gas recirculation valve, to poorly closing intake valves and the associated loss of compression. 

JetClean Tronic II, in combination with our Pro-Line JetClean Tronic II additives, eliminates problems with the fuel and intake system quickly and reliably.
