    • A phase recognition device for an internal combustion engine with a crankshaft comprising a transmitter disc (10) comprising incremental angular marking means and a sensor associated with the transmitter disc for generating a sensor signal representative of the passage of the incremental angular marking means in front of the sensor. The transmitter disc (10) rotates at half the speed of the crankshaft. The incremental angular marking means comprises at least two series of a multiplicity of incremental angular marks (12, 14), which extend over complementary angular portions of the transmitter disc (10), each series of a multiplicity of incremental angular marks (12, 14) causing the sensor to generate a distinct sensor signal.

    • Disclosed is a direct ignition system for an internal combustion engine incorporating a first magnetic sensor for determining the crank shaft position and a second magnetic sensor for determining the cam shaft position. A counter weight integral with the crank shaft includes two patterns of four slots each representative of the speed and position of two of four pistons, respectively. One of the slots of one of the patterns of slots is substantially wider than the remaining slots and as such represents a signature slot. The first magnetic sensor sends a signal to an onboard computer representative of the slot patterns as the crank shaft rotates. The cam shaft includes a magnet at one of its ends opposite the cam sprocket. The magnet includes a plurality of alternating pole sections in which predetermined areas of the pole sections differ in size. The second magnetic sensor is positioned adjacent the magnet such that it sends a signal indicative of a change from one pole to an adjacent pole of the magnet. By arranging the magnetic poles and the slots in an appropriate configuration, a timing diagram representative of the first and second magnetic sensor signals can be compared. By this, a single position on the timing diagram can be determined to isolate the position and speed of a particular piston and determine if it is in an exhaust or firing stroke. Therefore, engine position can be determined within one revolution of the crank shaft.
    • 公开了一种用于内燃机的直接点火系统,其包括用于确定曲轴位置的第一磁传感器和用于确定凸轮轴位置的第二磁传感器。 与曲轴一体的配重包括四个槽的两个图案,分别表示四个活塞中的两个的速度和位置。 插槽之一之一的时隙中的一个基本上比剩余的时隙更宽,并且因此表示签名时隙。 当曲柄轴旋转时,第一磁传感器将信号发送到表示槽模式的车载计算机。 凸轮轴包括在与凸轮链轮相对的一端的磁体。 磁体包括多个极性部分,其中磁极部分的预定区域的尺寸不同。 第二磁传感器位于磁体附近,使得其发送指示从磁极的一个磁极到相邻磁极的变化的信号。 通过将磁极和槽布置成适当的构造,可以比较表示第一和第二磁传感器信号的时序图。 由此,可以确定时序图上的单个位置以隔离特定活塞的位置和速度并确定其是否处于排气或击发冲程。 因此,可以在曲轴的一圈内确定发动机位置。
