Abstract: The present invention relates to an optimization system of a smart logistics network capable of providing an optimal plan in terms of an architecture of a logistics network of a shipper, the number and capacity of logistics centers, a transport network, a router, etc., in order to be able to minimize distribution cost and CO2 emission at the present time and over the medium and long term.

Abstract: A variable valve actuator may include a rocker arm which may be pivotally connected to a rocker shaft, and of which a rocker arm hydraulic pressure supply line and a rocker arm hydraulic pressure exhaust line may be formed therein, a variable control piston which may be fluid-connected to the rocker arm hydraulic pressure supply line and slidably interferes the rocker arm hydraulic pressure exhaust line to selectively close the rocker arm hydraulic pressure exhaust line according to supplying hydraulic pressure of the rocker arm hydraulic pressure supply line, an actuating portion which may be selectively fluid-connected to the rocker arm hydraulic pressure supply line and the rocker arm hydraulic pressure exhaust line by the variable control piston such that the actuating portion selectively protrudes according to the supplying hydraulic pressure of the rocker arm hydraulic pressure supply line, and a valve unit opened according to reciprocation of the actuating portion.

Abstract: A cooling circuit of an oil cooler for a vehicle that reduces the number of parts and provides an elegance appearance of the engine by applying a cooling circuit structure of a parallel type oil cooler having a good layout and a high cooling efficiency to configure the cooling circuit of the oil cooler having a simplified and independent flow path structure without any pipe coming out of the engine. The cooling circuit receives a cooling water of the lowest temperature through a cooling water inlet formed in a cylinder block to cool the oil cooler and directly connects the cooling water of the oil cooler to a cooling water intake established in a water pump.
