Abstract: A variable compression ratio engine according to an embodiment of the present invention comprises a first cylinder which performs an intake stroke and a compression stroke; and a second cylinder which performs a power stroke and the compression stroke, and is arranged to be adjacent to the first cylinder, wherein part of compressed air generated in the compression stroke of the first cylinder can be supplied to the second cylinder performing the intake stroke. Therefore, part of the compressed air generated in the compression stroke is supplied to the adjacent cylinder performing an intake stroke, thereby reducing a compression ratio and improving intake efficiency. In addition, the compression ratio in the compression stroke is variably controlled according to an operational state, thereby improving fuel efficiency, and reducing vibration and noise.

Abstract: The present invention relates to a method for bonding an Ex-Mani for a vehicle, wherein the method bonds a joint part which exhaust gas is joined in and penetrates to a turbine housing with an induction brazing method using copper-based filler metal and a high-frequency induction coil, thereby relieving fatigue strength in a bonding part between the turbine housing and the joint part, and preventing bonding defects such as thermal deformation, spatters, cracks, or back beads. More specifically, the present invention provides the method for bonding the Ex-Mani including the turbine housing and the joint part which discharges the exhaust gas of a vehicular engine after joining the exhaust gas in a single path, wherein the method comprises: a step of separately installing the high-frequency induction coil outside the bonding part; a step of spreading or applying the filler metal on the bonding part; and a step of welding the filler metal by heating the high-frequency induction coil.
