Abstract
An internal combustion engine for vehicles comprising a primary and an auxiliary engine unit each comprising vertically disposed cylinders and a crankshaft operatively connected to the respective cylinders. The crankshafts are arranged in parallel. A first output shaft is positioned parallel to both crankshafts and at an intermediate position between extensions of the crankshafts. The auxiliary engine unit is spaced apart from an end of the output shaft defining a space. The cylinders of each engine unit are arranged in staggered disposition. A clutch is disposed in the space between the auxiliary engine unit and the output shaft for transmitting an output of the auxiliary engine unit to the output shaft. A gear train comprises three gears including a first end gear secured to the crankshaft of the primary engine unit, a second end gear secured to an output shaft of the clutch, and an intermediate gear secured to the first output shaft engaging with both end gears. A switch provides for engaging the clutch when engine load exceeds a predetermined value.
