Model andControl Strategy of Jet Duty--cycle for LPG Engine
Translated Abstract
On the condition of theoretical air--fuel ratio （A/F）, a study on the strategy of open --loop control of jet duty--cycle for some low--power LPG engine was carried out. The throttle percentage and engineer speed were selected as the effecting factors of jet duty cycle by analyzing various effecting factors, and a multivariate linear regression equation for jet duty--cycle was fitted. The result showed the regression equation has a high accuracy, and the relative errors between the observations and predictions are less than 3.0~. The regression equation, instead of map of jet duty--cycle, can be used directly for software programming for open--loop control, and the overshoot can be down by 7.0% based on the application of new control system.
