In lubrication system, several filters with the different filtration capacity, i.e. collecting filter and fine filter, are installed in parallel and in series with the main oil passage respectively. Therefore, the filter can be divided into full flow type. The full flow filter, that is, the primary filter, is connected in series with the main oil passage, so all engine oil passes through it. It can filter out impurities with large particle size (diameter more than 0.1mm) in the engine oil, and the filter element is paper. In order to prevent the oil cut-off due to the blockage of the strainer, a bypass valve is installed at the head of the strainer. Once the bypass valve of the strainer is blocked, it can be opened to allow the unfiltered oil to be input into the main oil passage to ensure the lubrication of all parts of the real estate bureau.

風(fēng)流濾清器即細濾器，細濾器可以濾去直接的0.001mm以上的細小雜質(zhì)，它和主油道并聯(lián)，濾芯亦為紙質(zhì)。機油經(jīng)細濾器濾清后回到油低殼，由于發(fā)動機工作過程中總有一部分機油通過細濾器進行過濾，因此提高了總體濾清效果，延長了機油使用壽命。

The air flow filter is the secondary filter. The secondary filter can filter direct fine impurities above 0.001mm. It is connected in parallel with the main oil passage, and the filter element is also paper. The engine oil returns to the low oil shell after being filtered by the fine filter. Because part of the engine oil is always filtered by the fine filter during engine operation, the overall filtering effect is improved and the service life of the engine oil is prolonged.

全流式濾清器必須與分流式濾清器一起使用，不可只用分流式濾清器代替全流式濾清器。

The full flow filter must be used together with the shunt filter, and the shunt filter cannot be used instead of the full flow filter.

KTTA型柴油機使用的全流式機油濾清器由濾清器座和濾芯組成。濾清器座有三種類型：全流式機油濾清器座；旁通式濾清器座；組合式濾清器座。濾清器座有鋁制和鑄鐵制兩種：老式K38型用鋁制濾清器座；新式K38型和K50型用鑄鐵制濾清器座。

The full flow oil filter used in KTTA diesel engine is composed of filter base and filter element. There are three types of filter seats: full flow oil filter seat; Bypass filter base; Combined filter base. Filter seats are made of aluminum and cast iron: old K38 aluminum filter seat; The new K38 and K50 filters are made of cast iron.

全流式機油濾清器座，全部機油從冷卻器流到全流式機油濾清器座，經(jīng)濾芯到柴油機主油道。旁通式機油濾清器座只有部分機油留到旁通式濾清器座和濾芯。組合式機油濾清器座含全流式濾芯和旁通式濾芯。

Full flow engine oil filter base: all engine oil flows from the cooler to the full flow engine oil filter base and to the main oil passage of the diesel engine through the filter element. Only part of the oil in the bypass oil filter base is left to the bypass oil filter base and the filter element. The combined oil filter base contains a full flow filter element and a bypass filter element.

全流式機油濾清器座的組成由壓力調(diào)節(jié)閥、濾清器旁通閥和活塞冷卻閥。

The full flow oil filter base consists of a pressure regulating valve, a filter bypass valve and a piston cooling valve.

壓力調(diào)節(jié)閥——保持柴油主油道中的正確的機油壓力，并將主油道不需要的機油返回機油道。

Pressure regulating valve - maintain the correct oil pressure in the diesel main oil passage and return the unnecessary oil in the main oil passage to the oil passage.

旁通閥——在機油濾芯中阻力過大時。旁通機油，避免濾芯堵塞時柴油機因缺油而損壞。

Bypass valve - when the resistance in the oil filter element is too large. Bypass the engine oil to avoid damage to the diesel engine due to lack of oil when the filter element is blocked.

活塞冷卻閥——控制機油只流向有濾清器座的柴油機一側(cè)?；钊鋮s油道有一分開的活塞冷卻閥，控制機油流向與有濾清器座相對一側(cè)的活塞冷卻出道。

Piston cooling valve - controls the flow of oil only to the side of diesel engine with filter base. The piston cooling oil passage has a separate piston cooling valve to control the oil flow to the piston cooling outlet on the side opposite to the filter base.
