internal combustion engine, throttle valve, numerical research, experimental research
Abstract
In the article the simplified numerical research methodology was presented, to designate the throttle valve flow characteristics. It was agreed that it is the alternative for long and expensive experimental research, especially referring to the prototypes. The 6 subsystems in two groups were subjected to the analysis. In the first one, the flap throttles used in car engines were grouped, in the second one - motorcycle slider throttles. The experimental verification showed the alignment of the numerical concluding with the experimental one in some cases.
