摘要:
A sensor (16) is connected to a high pressure line (13) in a fuel injection system for an internal combustion engine. The sensor (16) produces an output current which is proportional to the pressure in the line (13). The current is converted into a corresponding voltage and a displayed a voltmeter (21). An alarm is produced when the voltage exceeds a predetermined value or range. A second voltmeter (23) is energized to display the voltage when the alarm is produced.
摘要:
A fluid pressure passageway (14) such as a high pressure fuel line in a fuel injection system is pressurized to an upper predetermined value. Then, the passageway (14) is isolated and the length of time for the pressure to drop to a lower predetermined value is measured. The greater the degree of leakage, the shorter the measured length of time. An alarm (24) is energized when the measured length of time is shorter than a predetermined length of time.
摘要:
A sensor (16) produces an electrical signal corresponding to the pulsating pressure in a high pressure fuel line (13) leading to a fuel injection valve (14), the pulsations being produced by opening and closing of the valve (14). The electrical signal and a reference signal are fed to a cathode ray tube display unit (18) to produce a Lissajous figure. The shape of the Lissajous figure indicates whether the Schnarren phenomenon is present and, if so, to what extent. The frequencies or amplitudes of the electrical signal and reference signal are compared to produce a signal indicating the difference therebetween which is fed to a digital display unit (22).
摘要:
The present invention provides early insulin secretion stimulators consisting of triterpenes represented by the following general formula (1) and/or triterpenes represented by the following general formula (2). [where R1 represents COOH, etc., R11 and R12 represent CH2OH, etc., X1 represents hydrogen or OH and X11, X12, X21 and X22 represent OH, etc.]
摘要:
The invention provides an early insulin secretion stimulator consisting of corosolic acid, etc. The early insulin secretion stimulator of the invention is capable of rapidly inducing secretion of insulin immediately after meals without inducing secretion of excess insulin in the absence of blood glucose increase.
