Key result
The Zuech constant volume technique and the Bosch rate of injection meter produced almost identical injection rate shapes, with integrated values within a few percent of physically measured quantities.
The newly developed Zuech constant volume technique produces almost identical injection rate shapes compared to the standard Bosch rate of injection meter.

Adds comparable injection measurement option; leaves open standardization in engine research.
This paper will discuss the fundamentals of the Bosch rate of injection meter which has been the standard measurement tool for the last 25 years and a newly developed tool which uses the Zuech constant volume technique. A fundamental and experimental comparison is presented. Using a high pressure accumulator type injector, each of the injection systems produced almost identical injection rate shapes. The integrated values of these traces (injection quantity) were within a few percent of the physically measured quantities.

Bower et al. (1991) studied this question. Zuech constant volume technique vs. Bosch rate of injection meter was evaluated on Injection rate shapes and integrated values (injection quantity). The Zuech constant volume technique and the Bosch rate of injection meter produced almost identical injection rate shapes, with integrated values within a few percent of physically measured quantities.
