ABSTRACT OF THE DISCLOSURE The present disclosure relates to internal combustion engines of the kind comprising two working cylinders arranged in vertical side-by-side parallel relationship, there being two oppositely working pistons in each cylin- der, and the movement of the four pistons being transmit- ted to a common drive shaft between the cylinders. The top pistons in each cylinder are connected to piston rods which in turn are secured to a crosshead and which cross- head has a pivotal connection for a connecting rod the other end of which is connected to drive a drive shaft. The lower or bottom two pistons are in like manner connect- ed through a crosshead to the drive shaft. Fuel injection occurs into a common precombustion chamber communicating with the midpoint of each cylinder between each of the two pistons in each cylinder. As to each cylinder intake air is ported in above the injector and exhaust air is ported out beneath the injector. The angular spacing of the cranks on the crankshaft is such that the intake control- ling pistons, being the upper one in each cylinder will be forced to lag behind the exhaust controlling piston, being the lower one in each cylinder, in such a manner that the exhaust porting is forced to open prior to the opening of the intake porting and said exhaust porting is forced to close prior to the closing of the intake porting.
