摘要： PURPOSE:To detect abnormality of the reference position signal and angular position signal of a crank shaft respectively by detecting the abnormality of either the reference position signal or position signal by a specific combination of logical states that the 1st and the 2nd flags indicate. CONSTITUTION:The 1st flag is placed in a specific logical state unless a specific number of the 2nd position signals T24 are generated after the 1st reference position signal T04 is generated. Further, the 2nd flag is set in a specific logical state if the 1st position signal T04 is generated after the 1st reference signal T04 is generated and before a specific number of the 2nd position signals T24 are generated. Then, the abnormality of an least either of the 1st reference position signal T04 and the 2nd position signals T24 is detected by the specific combination of the logical states that the 1st and the 2nd flags indicate respectively. Consequently, the abnormality of at least the reference position signal and angular position signal of the crank shaft is detected respectively.

摘要： PURPOSE:To test distinctively a multicylinder engine, cylinder by cylinder, by obtaining a cylinder identification signal from the signal of the ignition plug of the 1st cylinder and the pulse signal of the driving torque of a driving motor. CONSTITUTION:A testing engine 2 is rotated by the driving motor 1 and the pluse signal (d) of the driving torque is detected by a pulse signal detecting means 20. This pulse signal (d) and a No.1 pulse (b) as the pulse signal of the ignition plug of the 1st cylinder are sent to each cylinder identification output means 22 of a cylinder signal output device 21. When a 4-cylinder engine 2 is tested, the signal (d) is outputted in the order of the 1st, the 3rd, the 4th, and the 2nd cylinders, so the 1st cylinder is identified with the signal (d) and No.1 pulse (a) and then the 3rd, the 4th, and the 2nd cylinders are identified. Singnals classified by the cylinders are outputted from the output means 22 and the test is taken by using pieces of information classified by the cylinders.

摘要： PURPOSE:To improve accuracy of measurement of the top dead point of a piston by a relatively simple apparatus, by providing an encoder for detecting the rotary angle of a crank shaft, a sensor for detecting the movement amount of the piston, and a counter for the encoder. CONSTITUTION:An encoder 8 for detecting the rotary angle of a crank shaft 3 and a sensor 24 for detecting the movement amount (x) of a piston 2 are attached to an engine block 4. The crank shaft 3 is rotated rightward. When the piston position (x) becomes H+A, the crank shaft is stopped. Then it is rotated leftward. When the piston position becomes H, the content of the counter of the encoder 8 is made to be zero. The crank shaft is further rotated leftward. When H+A is reached, the crank shaft 3 is stopped. It is rotated rightward again. When the height H is reached, the pulse number per unit movement, which is sent by the encoder 8, is doubled. The rightward rotation is further continued. When the content of the counter becomes zero, the crank shaft 3 is stopped. The piston position at this time is the accurate top dead point.

摘要： PURPOSE:To obtain the top position signal of a cylinder in compression and explosion strokes in a fuel cycle very accurately and easily, by processing the output signals of a cam shaft rotating position detector and a fly wheel rotating position detector by an operator. CONSTITUTION:A fly wheel rotating position detector 5 outputs the fly wheel signal in correspondence with the so-called top position of a cylinder 1 as shown in (A). A cam shaft rotating position detector 8 outputs the cam shaft signal corresponding to the top position of the cylinder 1 at the rate of once per two strokes as shown in (B). An operator 10 outputs the fuel cycle signal is synchronization with the cam shaft signal as shown in (C). The width of the pulse of the fuel cycle signal is about the same as that of the fly wheel signal. In this constitution, the cam shaft signal is obtained only when the signal corresponds to compression and explosion strokes. Therefore, the top position signals at the compression and explosion strokes are readily and accurately outputted by the operator 10 as the fuel cycle signal all the time.

摘要： PURPOSE: To simplify a system and to detect precisely the combustion starting time by detecting the combustion starting time based on a microwave signal and a light signal.
CONSTITUTION: A microwave 1 is transferred to a cable Fc through a circulator 2. It is converted into a wave guide mode TE in a coaxial wave guide conversion part, converted into a coaxial mode TEM in the said part, conducted to auxiliary chamber AC, and entered in a main chamber MC. If a piston is not at a resonance position, the microwave is reflected and enters a circulator 2. Then it is separated from a transmission wave, it turns into a low frequency signal owing to a detector, and it is sent to a processing part. A photodiode outputs a spark signal following ignition. The processing part III processes the low frequency signal from the detector 3 at a peak detecting part 15, processes the light signal at a processing part 16, then outputs the time difference between the central peak of the microwve signal and one tenth the peak point of the light signal at a time difference computing part 17, and displays the injection time and angle on a display unit DD1W3.
