Fuel system, intake system and particulate filter cleaning with JetClean Tronic III or JetClean Tronic III Pro

Clogged fuel system

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

As a result, the sensitive nozzle head is constantly in contact with exhaust gases (including soot). Depending on the driving style and fuel quality, deposits quickly form at the fuel outlet holes on the nozzle head. The injected fuel can therefore no longer mix optimally with the air, which leads to higher fuel consumption and an associated increase in pollutant emissions. Over timer, more combustion residues such as soot are produced clogging the fine outlets even more. This leads to even poorer combustion and even to the blocking of the injector or failure of the system, which can result in costly repairs.

Clogged intake system

Another problem with direct-injection petrol and diesel engines is the lack of cleaning of the intake area. On the one hand it is contaminated by the exhaust gas flowing back through the valve overlap or the crankcase ventilation (deposits on the intake valves), and on the other hand by the exhaust gas recirculation system.

This connection between the exhaust and intake tracts sometimes causes enormous deposits on the intake side of the engine and on the intake valves. The resulting problems are manifold - from a completely contaminated intake area and a defective exhaust gas recirculation valve to poorly closing intake valves and the associated loss of compression. 

Clogged particle filter

Many diesel vehicles also suffer from a clogged diesel particulate filter (DPF). In many cases, this is caused by short distance trips that do not allow the filter to regenerate properly through free-burning, by defective sensors that control regeneration and lead to incomplete cleaning or by poor fuel quality, which can lead to faster clogging. 

If the filter remains clogged, this can have serious consequences such as engine damage due to excessive exhaust gas pressure. The increased load on individual engine components also increases the risk of high wear and expensive repairs to the engine, exhaust system or particulate filter.
