The invention discloses an LPG engine with a semi-balance drift angle and parabola mean camber line wing-shaped blade. A balance drift angle phi is formed between an angle bisector from the two side edges of an opening of a C-shaped ring (56a), additionally arranged on a crankshaft (57) of the LPG engine, of a crankshaft valve (56) to the circle center angle of the circle center of the crankshaft and a center connecting line from the circle center of the crankshaft to the circle center of a large head of a connecting rod, selecting is actually conducted in the range from 2 degrees to 22 degrees, and the value of 10 degrees is primarily used at present. According to a semi-balance method of a single-cylinder engine, the exciting force amplitude and compound upsetting moment of a resultant force elliptic equation are reduced, drift angle balancing is actually the appropriate offsetting of a balance gravity center, the inappropriate semi-balance of a single cylinder is improved, and the mechanism is worthy of be
