Abstract: A turbo charge system of an engine minimizes energy loss of exhaust gas as a consequence of a crossover pipe that connects exhaust manifolds respectively mounted to cylinder heads at both sides of the engine with each other and that is mounted in each cylinder head, and the crossover pipe is formed as a double pipe structure. The turbo charge system of the engine may include a pair of exhaust manifolds respectively mounted to cylinder heads at both sides of the engine; a pair of turbo chargers connected respectively to the pair of exhaust manifolds and increasing intake air amount by using energy of exhaust gas; and a crossover pipe connecting the pair of exhaust manifolds with each other, wherein a crossover pipe is mounted in each cylinder head.

Abstract: An intercooler assembly for a vehicle. The intercooler assembly may include an inflow portion on which an inflow hose is mounted, the inflow portion including a buffering space to temporarily accumulate an in-flowing air, a first cooling portion fluidly connected to the inflow portion, an outflow portion on which an outflow hose is mounted, a second cooling portion fluidly connected to the outflow portion, and a turnaround portion fluidly connecting the first cooling portion and the second cooling portion, wherein the turnaround portion changes a flow direction of the in-flowing air and guides the in-flowing air toward the outflow portion so as to discharge the air.

Abstract: A cooling apparatus of an exhaust gas recirculation system includes a first cooling portion, made of a first material, that receives recirculation exhaust gas; and a second cooling portion, made of a second, different material, that receives the recirculation exhaust gas from the first cooling portion and exhausts the recirculation exhaust gas out of the apparatus. A cooling method of an exhaust gas recirculation system includes receiving a recirculation exhaust gas in a first cooling portion made of a first material; cooling the recirculation exhaust gas in the first coolant portion; receiving the recirculation exhaust gas in a second cooling portion made of a second, different material; and cooling the recirculation exhaust gas in the second coolant portion.

Abstract: A method and system of controlling a swirl control valve includes determining whether a current condition is in Tip Out by detecting positions of VGT vanes and an EGR valve, fully opening the swirl control valve if the current condition is in Tip Out, and not opening the swirl control valve if the current condition is not in Tip Out.

Abstract: An EGR coolant control system according to an exemplary embodiment of the present invention may include a coolant exhaust pipe connected with the coolant supply pipe, an EGR coolant supply pipe connected with the coolant supply pipe and the coolant exhaust pipe, a coolant control plate that is disposed in a junction portion of the coolant supply pipe, the coolant exhaust pipe, and the EGR coolant supply pipe, and that controls supply of a coolant, and an actuator controlling the coolant control plate according to in engine rotation speed.
