Two cylinder-four stroke-internal combustion engine for e.g. quad, has piston with offsets shifted opposite to each other around angle counted in rotation direction to produce uneven ignition for obtaining road grid for vehicles

摘要

The engine has a piston working in different cranks of a crankshaft, where offsets of the piston are shifted opposite to each other around a displacement angle, which amounts around 90 degrees between the cranks. The displacement angle is counted in a rotation direction of the engine such that the cranks are arranged at 0 and 90 degrees to produce uneven ignition with ignition spacings from 270 and 450 degrees for obtaining road grid for motor vehicles.
