Abstract:
PURPOSE: A driving structure of air conditioner of automobile is provided to increase the freedom of design of an engine and to reduce noise. CONSTITUTION: A driving shaft(11a) of a power steering pump(10) and a driving shaft(11b) of an air conditioner compressor(12) are placed coaxially with each other. The driving shafts are connected with each other by a joint shaft(13) to directly transmit power. Damping rubbers are mounted in the joint shaft to intercept vibration and to damp the shock due to sudden acceleration or deceleration to increase the durability of the air conditioner compressor. The driving shafts are directly connected to simplify the whole structure of an engine and reduce the power loss and noise.

Abstract:
PURPOSE: An intake port of a lean-burn engine and a core thereof are provided to improve fuel efficiency of the engine, and to reduce harmful gas discharge by manufacturing the linear port and the swirl port with the core and installing the injector properly. CONSTITUTION: An intake port of a lean-burn engine is composed of a linear port(1) and a swirl port(3), and a connecting part(5) is formed between the linear port and the swirl port to supply fuel from the injector. The linear port is separated from the swirl port excluding the connecting part to form swirl efficiently within the range of lean-burn operation of the engine. The swirl port is contacted to the linear port with a single circle(7) in the installation portion of the injector, and two cylinders(9) are branched from the circle to the linear port and the swirl port. The linear port is communicated with the swirl port in the intersection.
Abstract:
PURPOSE: A flange coupling structure of a hydraulic type exhaust manifold is provided to achieve improved coupling force between the inlet flange and cylinder head, while minimizing deformation of flange. CONSTITUTION: An exhaust manifold includes first to fourth runners(15 to 18) connected to each exhaust port of a cylinder head. First to fourth inlet flanges(11 to 14) which are not connected with each other are welded to the outer surfaces of first to fourth runners, respectively. A coupling portion(20) to be coupled to the contact surface of the cylinder head through a bolt(or nut), is formed at the outer surfaces of the inlet flanges, so that first to fourth inlet flanges are independently coupled to the exhaust port of the cylinder head.

PURPOSE: An optimum engine output is maintained by improving respondence of valve shutting in a continuous variable valve timing device. CONSTITUTION: A continuous variable valve timing device comprises a valve timing controller(10) to generate valve timing variable control signal by an engine rpm of an automobile. An oil control operating portion(20) has an advance hole and a retard hole to convert oil flow passing the advance hole and retard hole to form an advance passage and retard passage by received valve timing variable control signal. A cylinder head is mounted with the oil control operating portion. A vane housing(50) has an advance chamber and a retard chamber corresponding to the advance hole and the retard hole to change a cam shaft position by oil pressure difference of the advance chamber and the retard chamber.
