WebFor a compression ignition (CI) free piston engine linear generator (FPLG), injection timing is one of the most important parameters that affect its performance, especially for the one-stroke starting operation mode. In this paper, two injection control strategies are proposed using piston position and velocity signals. It was found experimentally that the injection … WebWhile the minimum compression a 2 stroke engine needs to complete the combustion process is 90 psi, you cannot expect a leaf blower with such a low compression reading to produce much power. According to most manufacturers, even a small 30 cc leaf blower engine should have a reading of 100 psi.
