Abstract

Engine
torque and power are one of the problems in LPG applications for vehicles with
first-generation converter kits. Therefore, this paper presents the
results of the development of a mixer prototype to be applied to LPG fueled
vehicles with first-generation converter kits (converters and mixers). A series
of work is done beginning from design, prototyping, and
ending by testing of prototypes to vehicles. The prototyping
process includes design activities and machining activities. Design activities
are carried out with Pro-Eng software and machining activities are carried out
with a turning machine. Furthermore, the prototype mixer was tested on a 1500
cc engine. Output torque and power are measured on a chassis dynamometer with
the standardized test method. The results of this study indicate that the
mixer with secondary venturi shows better output torque and power than a
standard mixer at almost all daily speeds for public fleet and private
vehicles. In conclusion, mixer with secondary venturi is feasible to
implement, especially for public transport with heavy loads.
