Development of a New Measurement Tool for Fuel Injection Rate in Diesel Engines

A new instrument for the measurement of fuel injection rate in diesel engines was developed. The instrument, whose measurement principle is based on the Zeuch's method, i.e., the constant volume method, incorporates a device for the precise calibration of the volume elasticity of the fuel. This instrument was proved experimentally to have a capability of measuring injection rate with +- 1% accuracy up to an injection pump rotating speed of 2500 rpm.
