【Abstract】 The full load Characteristics and rated speed fuel consumption characteristics have been carried cut on a turbochanged engine using the turbocharger with a variable throat device. The results show that both engine performance at low speed nd specific fuel consumption are obviously improved. Because it is simple in design,reliable in construction, practical in use and easy in control, the variable throat device is valuable to intioduce into practical application.更多还原
