Abstract
An intake regulating system of an engine equips with an intake regulating-device connected with a breather hose for drawing the oil vapor and the leaked gases from the crankcase of the engine, thereby to mix with outside air to feed into the engine for re-combustion. The intake regulating-device comprises a housing and a pressure-sensing valve. The housing has an air inlet hole, an air outlet hole, and a slender hole. The air outlet hole and the slender hole both are in communication with the air inlet of engine via an intake manifold for generating a pressure difference thereby to drive the pressure-sensing valve. Preferably, the intake regulating-device provides a pair of regulating knobs for adapting the pressure-sensing valve with various intake volumes of an engine.
Claims14
An intake regulating system of engine having an intake regulating device conneced to an intake path of an engine, wherein the engine comprising a crankcase, a PCV (Positive Crankcase Ventilation) device, an intake manifold and an air inlet, and wherein the intake regulating-device comprising:
- a housing, having an air inlet hole, an air outlet hole and a slender hole, the air inlet hole connected to an air cleaner and a breather hose which is communicated with the crankcase;
- both of the air outlet hole and the slender hole connected to the air inlet of engine via the intake manifold;
- and
- a pressure-sensing valve movably installed inside the housing for controlling the path between the air inlet hole and the air outlet hole of the housing according to the pressure difference between the air outlet hole and the slender hole,
- wherein the air outlet hole of the housing connects the PCV device and the intake manifold of the engine via a three-way joint and communicates with the air inlet of the engine via the intake manifold.
