The method for calculating the fuel injection amount of a fuel vapor dual purge system may include the steps of calculating, by a controller, volumetric efficiency of a combustion chamber, determining, by the controller, a fuel vapor detection delay time at which the fuel vapor is detected in a surge tank according to the calculated volumetric efficiency of a combustion chamber, calculating, by the controller, a time at which the fuel vapor is injected into the combustion chamber based on the determined fuel vapor detection delay time, and calculating, by the controller, a fuel vapor total injection amount at the time at which the fuel vapor is injected into the combustion chamber. The method may be performed in a turbocharger operation section.

Method and system for calculating fuel injection amount of fuel vapor dual purge system

The present disclosure relates to a dual purge system for a vehicle, which varies a purging amount depending on a pressure condition of an intake manifold surge tank to realize desired purging efficiency suitable for a vehicle driving range. In the dual purge system, by desorbing fuel evaporation gas from all canisters in a state of engine negative pressure, a purging amount increases thereby improving fuel efficiency, and by desorbing the fuel evaporation gas from some canisters in a state of engine positive pressure, flow resistance of the gas is reduced in comparison with previous flow resistance thereby increasing desorption efficiency.

An oil filter system for a vehicle may provided at a cylinder block of an engine for collecting engine oil from a blow-by gas generated in a crank case. The oil filter system may include a blow-by path 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 that is a space formed between the crank case and the blow-by path, a filter partition disposed to divide the filter case into two spaces, and configured to collect the engine oil contained in the blow-by gas, and an oil pan mounted in the cylinder block for collecting the engine oil that have been collected by the filter partition. The filter partition may collect the engine oil in a forward direction flow and a reverse direction flow of the blow-by gas.
