Abstract: An engine includes: a first part that is provided in a first passage that interconnects an inside of a crankcase and a part of an intake passage at a downstream side of an adjustment part adjusting an intake air amount and changes gas flow in the first passage; and a second part that is provided in a second passage that interconnects the inside of the crankcase and a part of the intake passage located at an upstream side of the adjustment part and changes gas flow in the second passage. If an engine temperature is higher than a given value, and the degree of fuel decreasing correction exceeds a given value, the first part decreases the gas flow rate through the first passage and the second part restricts a flow direction in the second passage to a direction in which gas flows to the crankcase from the intake passage.

Abstract: Methods and systems are provided for flowing crankcase gases through an aspirator arranged in a PCV line. The aspirator regulates PCV flow, and may also generate vacuum depending on a position of a pintle extendable across a horizontal passage of the aspirator. When regulating PCV flow and not generating vacuum, the aspirator is fully closed and crankcase gases in the horizontal passage are metered through an orifice in the pintle. When generating vacuum, the aspirator is at least partially opened and PCV flow through the horizontal passage generates vacuum at a vacuum port of the aspirator.

Abstract: This invention is to provide a fuel-air separation structure improvement for engine blow-by, which features an extra oil recirculation tube set up in between the bottom of the fuel-air separator and the engine, where the flow connection of the oil recirculation tube is controlled by a check valve, and the direction of the check valve is enabled only in a unidirectional way, pointing from the fuel-air separator to the crankcase of the engine, whereas the reverse direction is being cut off. By means of the aforementioned structure, the problems of carbon deposits in engine and exhaust pollution due to an excess of oil along with blow-by in the fuel-air separator can thus be substantially improved.
