摘要： PROBLEM TO BE SOLVED: To provide a device for measuring an ignition charging signal generated by a coil of a coil on plug device of an internal combustion engine. SOLUTION: This signal detector 12 is provided with an insulating substrate having a first flat conductive layer on a first surface and a second flat conductive layer on a second surface. The first layer is connected to a signal wire, and the second layer is connected to an earthing wire. When the signal detector 12 is held in close contact with a coil 4 of the coil on plug 2, an ignition signal generated by the coil 4 to pass a plug 6 is detected. The detected signal is displayed and analyzed by connection to the signal analyzer. The amplitude of the signal output by the signal detector is controlled to various coils having different output signal strength by varying the surface area ratio of the first layer to the second layer.

摘要： PROBLEM TO BE SOLVED: To provide an ignition timing control function confirmation method allowing visual evaluation of a warp ignition control. SOLUTION: In the ignition timing control function confirmation method of an ignition device 2 having a plurality of ignition timing characteristics, the optimum ignition timing is obtained even at the time of an acceleration/ deceleration. A dummy pulsar voltage waveform signal P corresponding to an engine revolution number and an accelerator pedal open degree is outputted from an optional wave form generation means 1 and the dummy pulsar voltage waveform signal P outputted from the optional waveform generation means 1 is inputted to the ignition device 2, i.e., an object to be inspected. The dummy pulsar voltage waveform signal P and a primary voltage V of an ignition coil 3 generated by an operation of the ignition device 2 to which the dummy pulsar voltage waveform signal P is inputted are inputted to a voltage phase difference measuring means 4 and an ignition time control function of the ignition device 2 is confirmed from a phase difference of the dummy pulsar voltage waveform signal P and the primary voltage V of the ignition coil 3.

摘要： PURPOSE:To accurately measure the firing internal, in an firing interval measuring device, of an internal-combustion engine by comparing the phases of the signals respectively developed at an ignition timing and a top dead center. CONSTITUTION:A first detector 5 is made up of a plug ignition sensor which is clipped to the ignition plug code 4 of the first cylinder, for example. A second detector 6 is made up of a pressure sensor which is fit to the head part of the first cylinder and applied for detecting a top dead center. A phase comparing circuit 7 finds a difference between the phases of the signals, one of which indicates said ignition timing and the other of which indicates the top dead center. In the figure, 9a is an analogue display consisting of meters and 9b is a digital display. The firing interval may be thereby accurately measured.
