Abstract: A linear engine-alternator combination power system was developed for Hybrid Electric Vehicle
(HEV) application. The linear engine prototype was accomplished based on a two-stroke original engine using
modification of a mechanical system and an electronical control system. According to the experimental objective
at earlier stage, a measurement and control system was developed including a transient data acquisition system
and the software based on LabVIEW. Starting process control of the engine was realized after the design of
software and hardware based on Infineon processing chip XC167CI. The feasibility of the prototype was verified
with some exploratory experiments made to study the linear engine movement characteristics. The results show
that the developed prototype can operate normally.

Key words: hybrid electric vehicle (HEV), linear engine, control system, data acquisition system
