Abstract: PURPOSE: A turbine housing of a vehicular turbocharger is provided to improve the durability of a partition wall which corresponds to repeated expansion and compression by forming a slit to the partition wall. CONSTITUTION: A turbine housing of a vehicular turbocharger comprises a turbine wheel accommodating chamber(15), a scroll part, a partition wall(14), and one or more slits(18). The turbine wheel accommodating chamber is shaped into a circular hole in order to position a turbine. The scroll part is internally formed with the turbine wheel accommodating chamber. The scroll part forms an exhaust gas passage along the rotational direction of the turbine wheel. The partition wall partitions the passage of the scroll part into two. The slit is radially formed on the partition wall.

Abstract: PURPOSE: A PCV valve of an engine is provided to enhance the flow of blow-by gas since if a vehicle runs under a cold weather condition, the freezing of the moisture in blow-by gas is prevented. CONSTITUTION: A PCV valve of an engine comprises a valve body(10), a plunger(20), an elastic member(30) and a freezing prevention unit. The valve body comprises an inlet(11) and an outlet(12). A fluid passage is formed in the valve body. The plunger is prepared on the fluid passage and moves back and forth by the pressure change of blow-by gas and intake manifold. The elastic member is prepared on the fluid passage and presses the plunger to close the fluid passage. The freezing prevention unit is prepared on the plunger and prevents the freezing of the fluid passage.

Abstract translation: 目的：提供发动机的PCV阀，以增强窜气的流动，因为如果车辆在寒冷的天气条件下行驶，则防止窜气中的水分冻结。 构成：发动机的PCV阀包括阀体（10），柱塞（20），弹性构件（30）和防冻单元。 阀体包括入口（11）和出口（12）。 在阀体中形成流体通道。 柱塞在流体通道上准备，并通过窜气和进气歧管的压力变化来回移动。 弹性构件在流体通道上制备并按压柱塞以关闭流体通道。 在柱塞上准备防冻单元，防止流体通道的冻结。

Abstract: PURPOSE: A twin scroll type turbocharger is provided to prevent cracks as the relative displacement difference due to the thermal deformation in a barrier and peripheral portion is absorbed by a reduced section portion. CONSTITUTION: A twin scroll type turbocharger comprises a barrier(1), a periphery portion(3), and a reduced section portion(5). The barrier divides an exhaust gas flow path. The periphery portion forms the exhaust gas flow path, and is connected to the barrier. The reduced section portion is formed between the barrier and the peripheral portion, and absorbs thermal deformation generated between the reduced section portion and the barrier.
