Description
Technical field
Single cylinder diesel technical field is the utility model is related to, espespecially a kind of single cylinder diesel cleaner.
Background technology
In single cylinder diesel, increasing single cylinder diesel has all carried out direct-injectionization improvement, direct injection combustion mode
Benefit be fuel-efficient, discharge is few, easily starts.But the nozzle opening of used fuel injector is more much smaller than conventional diesel, directly
Spray formula diesel engine requires very high to the cleannes of diesel oil.Diesel oil on the rural market of China, especially under-developed area
Cleannes all do not reach requirement, if do not filtered to diesel oil, injection pump and fuel injector can be caused often stuck, so as to cause
The frequent scram of diesel engine.Therefore, diesel engine with direct injection in fuel tank between fuel injector, will typically set diesel oil filtering to fill
Put.
At present, typically diesel oil is filtered by cleaner, the diesel oil after filtering is entered by injection pump and fuel injector
Enter combustion chamber to be burnt, in actual applications, the excess oil for being introduced into combustion chamber can be typically left in fuel injector, in the prior art
When excess oil is reintroduced back to typically by oil returning tube the operated fuel injection that next time is carried out in injection pump, but used in fact with machine
Between extension, spot can be produced inside machine, these usual spots, which can incorporate, to be entered in the diesel oil of combustion chamber, therefore, spray
Diesel oil in the oil returning tube of oily device often contains more impurity, is directly entered if without filtering by fuel injector and fired
Room is burnt, injection pump is not only resulted in and fuel injector is often stuck, so as to cause the frequent scram of diesel engine.Also as impurity
In the presence of causing diesel oil not burn fully, and then can not ensure also produce and can produce while machine efficiently runs well
The harmful tail gas of poison, so as to cause the pollution of environment, influences the living environment and health of the mankind.
Therefore, the applicant is directed to studying a kind of single cylinder diesel cleaner.
The content of the invention
The purpose of this utility model is to provide a kind of single cylinder diesel cleaner, ensure that into injection pump, fuel injector and
