A cruciform internal combustion reciprocating engine characterized by two right angularly related pairs of axially spaced cylinders with related piston units including pairs of axially aligned, axially spaced pistons, each piston is engaged in one of the cylinders. The pistons of each unit are rigidly connected by an elongate yoke. A crank shaft has an eccentric crank pin at right angle to the axes of and positioned between the cylinders of the pairs of cylinders. A double isosceles sliding block linkage motion-translating mechanism drivingly couples the crank pin and the yokes and includes a twin eccentric disc driver rotatably carried by the crank pin with the discs thereof rotatably engaged with the yokes. The pistons of the piston units include elongate annular bearing sleeves in rotary bearing engagement about the pistons and in linear sliding and rotary bearing engagement with the bores of related cylinders. The bearing sleeves transmit high side loading forces directed onto the pistons by the motion-translating mechanism and their related yokes onto the cylinders as the pistons approach both top and bottom dead center. The bearing sleeves maintain the pistons aligned in their cylinders and guide the piston units linearly as they reciprocate.
