Abstract
An engine apparatus that utilizes a gas pressure regulation valve not only for pressure adjustment but also for removal of lubricant. An engine apparatus includes a blow-by gas returning device to return a leakage of blow-by gas from a combustion chamber to an intake system. The engine apparatus includes an expansion chamber, into which the blow-by gas is introduced from the gas pressure regulation valve. In the expansion chamber, lubricant contained in the blow-by gas is isolated. The blow-by gas is returned to an intake side of an engine from the expansion chamber.
