摘要： PROBLEM TO BE SOLVED: To suppress sludge becoming likely to be generated in oil of an internal combustion engine when a fuel containing alcohol is used and to suppress bad influence of the generation of sludge on lubrication by the oil in the engine.
SOLUTION: In the case that concentration of alcohol of the fuel is high, a gas flow rate of blowby gas returned from a crank case 10 to an intake passage 3 increases compared with the case that concentration of alcohol in the fuel is low, for example, a fuel of which alcohol concentration is 0% is used and more blowby gas containing much moisture is returned to the intake passage 3 quickly. Thus, sludge is suppressed to become likely to be generated in the oil of the engine 1 while the fuel containing alcohol is used and the bad influence on the lubrication by the oil in the engine 1 caused by the sludge generation is suppressed.
