Oil filter system for vehicle

Abstract

An oil filter system for a vehicle is provided at a cylinder block of an engine and collects engine oil from blow-by gas generated in a crank case. The oil filter system may include a blow-by path configured to recirculate the blow-by gas so that the blow-by gas generated in the crank case is combusted together with a fuel-air mixture, a filter case formed between the crank case and the blow-by path, filters disposed in the filter case to collect the engine oil contained in the blow-by gas, and an oil pan mounted in the cylinder block to collect the engine oil collected at the filters, wherein the filters collect the engine oil in a forward direction flow and a reverse direction flow of the blow-by gas.

What is claimed is: 
     
         1 . An oil filter system for a vehicle, which is provided at a cylinder block of an engine and collects engine oil from a blow-by gas generated in a crank case, the oil filter system comprising:
 a blow-by path configured to recirculate the blow-by gas so that the blow-by gas generated in the crank case is combusted together with a fuel-air mixture;   a filter case formed between the crank case and the blow-by path;   filters disposed in the filter case to collect the engine oil contained in the blow-by gas; and   an oil pan mounted in the cylinder block to collect the engine oil collected at the filters,   wherein the filters collect the engine oil in a forward direction flow and a reverse direction flow of the blow-by gas.   
     
     
         2 . The oil filter system of  claim 1 , further comprising a forward baffle plate disposed between the crank case and the filter case, and a reverse baffle plate disposed between the filter case and the blow-by path. 
     
     
         3 . The oil filter system of  claim 2 , wherein the forward baffle plate and the reverse baffle plate are provided with pores through which the blow-by gas passes. 
     
     
         4 . The oil filter system of  claim 3 , wherein the filters include:
 a forward filter for filtering the blow-by gas passing through the pores of the forward baffle plate; and   a reverse filter for filtering the blow-by gas passing through the pores of the reverse baffle plate,   wherein the forward filter and the reverse filter collect the engine oil when the blow-by gas passes through the forward filter and the reverse filter.   
     
     
         5 . The oil filter system of  claim 4 , wherein the engine oil collected at the forward filter or the reverse filter drops down by its own weight, and the dropped engine oil is collected at the oil pan through an oil collection port. 
     
     
         6 . The oil filter system of  claim 2 , wherein the forward baffle plate and the reverse baffle plate are integrally formed with the cylinder block. 
     
     
         7 . The oil filter system of  claim 1 , wherein the filters include at least two filters to collect the engine oil in each of a forward direction flow and a reverse direction flow of the blow-by gas. 
     
     
         8 . The oil filter system of  claim 1 , wherein a filter in the filters is formed of a fiber material. 
     
     
         9 . The oil filter system of  claim 1 , wherein a filter in the filters is formed of a soft and downy fleece material. 
     
     
         10 . The oil filter system of  claim 1 , wherein the cylinder block is formed to include a space in which the oil pan is mounted, the crank case, the filter case, and the blow-by path, which are spatially separated from each other. 
     
     
         11 . The oil filter system of  claim 1 , wherein each filter in the filters is formed of a fiber material. 
     
     
         12 . The oil filter system of  claim 1 , wherein each filter in the filters is formed of a soft and downy fleece material.
