An investigation about generating electric power on operated parameters of powerpack utilizing linear engine

The research shows the experimental results for a free piston linear engine according to operation conditions of the linear engine and the structure of linear generator for generating electric power. Each parameter such as input calories value, equivalence ratio, spark timing delay, electrical resistance and air gap length were settled for identifying the combustion characteristics of the linear engine. As a result, the piston frequency was 57.2 Hz and the maximum generating power was 111.3 W where the operation conditions were as follows: 1.0 of equivalency ratio, 1.5ms of spark timing delay.
