Filed: 1988-01-29
Abstract: PURPOSE:To rapidly plot a smooth curve by appropriately determining the step interval DELTAt of a parameter (t) required at the time of expressing a Bezier cubic curve on a straight line approximation basis in accordance with the shape of the curve. CONSTITUTION:A difference vector between a current plot point for plotting a Bezier cubic curve Pt (0<=t<=1) and a plot candidate point to be forecasted as the next plot point is found out and an angle formed by said difference vector and a difference vector between the preceding plot point and the current plot point is calculated. The angle theta is compared with a previously determined limit value thetaL and whether the plot candidate point is used as the succeeding plot point or not is determined in accordance with the compared result. In case of 'NO', a new plot candidate point is found out by using the intermediate (t) value between the (t) value of the current plot point and the (t) value of the current plot candidate point. Thereby, the step interval can be set to a small value in a curved part with a small radius of curvature and set to a large value in a curved part having a large radius of curvature. Consequently, a smooth curve can be rapidly plotted.

Title: Compression ratio-variable direct injection diesel engine
Inventor: OGAWA HIROSHI
IPC: F02B75/04
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of smoke due to the reduction of the swirl ratio by shortening the stroke length of a piston to reduce the compression ratio of a combustion chamber with a compression ratio changing means, and reinforcing a swirl with a swirl reinforcing means. SOLUTION: The compression ratio is determined by a setting map in response to the engine speed and load. A control unit 20 operates a motor 19, rotatively displaces a ring gear 17, changes the initial phase angle, and changes the compression ratio so that the compression ratio is made the largest at the time of a start or at the time of a low load at a low speed and the compression ratio is made smaller as the speed and the load are increased. When the compression ratio is changed by the stroke length of a piston, the swirl ratio at the compression top dead center is reduced. To compensate this, the control unit 20 squeezes a swirl control valve 7 when the compression ratio is low, increases the swirl ratio at a compression start, increases the swirl ratio near the compression top dead center, and realizes the swirl ratio as required.
