Abstract: PURPOSE: A control method of a diesel engine is provided to prevent a shock in engine start by reducing a maximum engine output at a first speed of a transmission without changing a design of a power train. CONSTITUTION: A control unit outputs a control signal to a traveling sensor of a vehicle. The traveling sensor detects velocity and engine RPM(Revolutions Per Minute) from a velocity sensor and an engine RPM sensor and then transmits the data to the control unit. The control unit reads the velocity and engine RPM from the traveling sensor, sets a shift level and calculates a gear ratio. If the first shift level is selected, the control unit outputs a control signal to inject fuel for reducing engine output corresponding to the first gear ratio and returns to the main routine. Otherwise, the control unit outputs a control signal to inject fuel corresponding to a shift gear ratio and returns to the main routine. Therefore, a power train is applied to a vehicle without changing a design.

Abstract: PURPOSE: The present invention is directed to an apparatus and method for controlling the aerodynamic behavior of an aerosol jet stream used to process a solid surface provided within a processing chamber. More specifically, the present invention is directed to an aerosol chamber and the processing of a solid surface, such as a silicon wafer, for cleaning a contaminated surface while maximizing contaminant particle removal efficiency. The present invention also applies to the coating of a surface for improving even particle deposition. CONSTITUTION: An aerosol cleaning apparatus and a method of treating a substrate within such an apparatus prevent contaminant recirculation by controlling the post-impingement exhaust flow through control of the aerodynamic behavior of the contaminant laden exhaust stream. By the present invention, the post-impingement exhaust flow is divided into two streams. A first stream is the main stream flowing initially over the contaminated side of the wafer and carrying most of the suspended contaminants into the exhaust. The second stream flows initially over the cleaned side of the wafer and eventually into the exhaust stream. A flow separator is provided for dividing the post-impingement aerosol spray into plural flow streams. Additionally, the aerosol chamber can advantageously include a shroud positioned within the aerosol chamber just to the side of the nozzle but further away from the exhaust than the nozzle for restricting flow from the second post-impingement stream around the nozzle and into the first post-impingement stream. In accordance with a preferred embodiment, the apparatus is designed for cleaning the surface of a semiconductor wafer by impinging the surface with a cryogenic aerosol spray.
