Abstract: PURPOSE: A charging pressure control valve of a turbo charger is provided to prevent the leak of the exhaust gas by blocking the exhaust gas passing a bypass passage by closely contacting a section change part and a section change receiving part. CONSTITUTION: A charging pressure control valve of a turbo charger is composed of a valve body(1), a valve seat(3), a valve(7), a valve supporting part(11), a section change part, and a section change receiving part. A bypass passage bypassing the turbo charger with the exhaust gas is formed in the valve body. The valve seat is installed inside the valve body. The valve has a valve head(5) which opens/closes the bypass passage with the relative position change about the valve seat by the lineal sliding motion. The valve supporting part is integratedly formed in the valve body to guide the stem of the valve linear-slidably. The valve head is closely contacted to the valve supporting part by linear-sliding at the condition opening the bypass passage. The cross section of the section change part is gradually expanded according to the longitudinal direction of the stem.

Abstract: A structure for reinforcing a bulkhead of an engine cylinder block is provided to facilitate rotation of a crankshaft by firmly maintaining a mounting state of a main bearing cap. A structure for reinforcing a bulkhead of an engine cylinder block comprises a mounting part(12a) at which a main bearing cap(30) is mounted. The mounting part is formed at the lower end portion of a bulkhead(12). A under cut(12c) is formed at both corner sections(12b) of the mounting part. The bulkhead is formed at a cylinder block to partition the lower space of a cylinder. The main bearing cap has a journal support section for supporting a journal of a crankshaft. Both ends of the main bearing cap are coupled with the lower end of the bulkhead through a bolt. A support state of the crankshaft is stabilized by the main bearing cap, so that the crankshaft easily rotates and thus vibration and noise are reduced during an operation of an engine.
