Abstract: A vehicle engine is provided to increase the crank offset and compression ratio in the low speed region and decrease in the high speed region by the tilting of cylinder. A vehicle engine(1) comprises an engine case(2); a piston(10) connected to a crank shaft(20) arranged inside the engine case through a connecting rod(15); a cylinder(30) which forms a combustion chamber with the piston arranged inside and is arranged so that the central axis is offset from the crank shaft; and a pivot unit(40) which is arranged between the cylinder and the engine case and, when the RPM of the crank shaft is increased, reduces the offset degree and compression ratio by rotating the cylinder so that the central axis of the cylinder becomes close to the crank shaft.

Abstract: A balance shaft structure is provided to reduce the number of parts by arranging a crankshaft and two balance shafts in a longitudinal direction so that the balance shafts can be driven without an additional idler, and to remove noise generated by a gear due to the elimination of the gear. A balance shaft structure arranges a balance shaft longitudinally relative to a crankshaft, and connects the crankshaft to the balance shaft using a double-sided chain(90), so that the balance shaft is driven without an additional gear, that is, idler. In the balance shaft structure, two balance shafts are arranged continuously in a longitudinal direction. One of the balance shafts is connected to the outer surface of the chain, while the other balance shaft is connected to the inner surface of the chain.
