A linear engine has advantages in terms of volume and weight, because there are no rotating parts. Thus, it is considered that linear engines might be suitable in hybrid vehicles. However, the linear engine has challenges in terms of the engine ignition timing and efficiency, so the engine has not been commercialized yet. In this study, the dynamic and combustion characteristics of the linear engine might be specified by various loads which are changed by conductance. The engine used in this experiment consists of two combustion chambers, four compressors, two linear alternators and a mover with a piston head and magnets. The way fuel is supplied in the experiment is by propane fuel being mixed with air in the carburetor, then being delivered into combustion cylinders via compressors. In the experiment, conductance is altered from 0.04 to 0.16mho, and the ignition timing is ahead by just 5.0mm from the maximum stroke. As a result of the experiment, frequency, stroke, input calories and maximum pressure are decreased when the conductance is increased. Meanwhile, IMEP, generation efficiency and electric power are increased when the conductance is increased. Therefore, it might confirm that high conductance generates more efficient electric power, but that thermal efficiency is the highest in the state of 0.08mho.
