Authors Abstract
Content
AFTER stating the general conditions affecting injection systems and, in particular, the difficulties of small cylinder size, the authors treat simple systems analytically, and demonstrate experimentally the validity of their treatment, limited, in the first instance, to open nozzles. The variables investigated include pipe length, engine speed, nozzle dimensions, throttle position, and also the viscosity, elasticity, and density of fuels. Conclusions are summarized.
The authors next state the general conditions in the more usual systems embodying spring-loaded nozzle valves, piping, and special pump delivery valves, and gave a general mathematical treatment of these factors. They also investigate these systems experimentally, and here discuss the effects of variables: speed, throttle opening, pump delivery valve design, nozzle conditions. They conclude with deductions of value to engine designers.
