摘要： A piston with a piston body extending along a longitudinal central axis and having a crown portion and a pair of pin bosses is provided. The crown portion includes a combustion wall with a combustion bowl formed therein and a pair of ribs depending from the combustion wall. One of the ribs depends from the combustion wall directly below the combustion bowl, and the other rib is radially spaced from the combustion bowl. As such, one of the ribs depends lower along the longitudinal central axis than the other of the ribs. The ribs provide support to the crown portion and also act as a heat sink to extract heat from the combustion wall.

摘要： An external auto-ignited four stroke cycle gas engine with a combustion chamber which is arranged in the piston rotation symmetrically with regard to the cylinder axis and which in the upper dead center point of the piston absorbs nearly the total gas-air mixture. The engine, furthermore, includes means for imparting turbulence upon the gas-air mixture about the longitudinal cylinder axis, and also has a trough which is arranged in the cylinder head, and into which a spark plug extends. The combustion chamber in the form of a truncated cone open and widening toward the cylinder head has a substantially plane bottom while the greatest diameter of this truncated cone-shaped combustion chamber equals from 55 to 70% of the piston diameter and the depth of this combustion chamber is in a range from 15 to 20% of the piston diameter. The mantle surface of the combustion chamber is at an angle of from 10.degree. to 30.degree. inclined relative to the longitudinal axis of the cylinder. The trough into which the spark plug extends is truncated cone shaped and located entirely above the opening of the combustion chamber. The greatest diameter of the trough amounts to about twice the diameter of the thread of the spark plug while the depth of the trough amounts to from 20 to 25% of the trough diameter. Adjacent to and communicating with the trough is an ignition passage which ends in a tip at the longitudinal cylinder axis.The present invention relates to an external auto-ignited four-stroke cycle gas engine with a combustion chamber which is arranged in the piston rotation-symmetrically with regard to the cylinder axis and which in the upper piston dead center point absorbs approximately the entire gas-air mixture, the gas engine being provided with means for generating turbulence of the gas-air mixture about the cylinder axis and furthermore being provided with a depression provided in the cylinder head while an ignition plug extends into this depression.It is an object of the present invention to provide an engine of this type which in spite of the fact that its exhaust gases are substantially free from harmful components has a low fuel consumption and a high output.
