The deficiencies of the needle gun were more than compensated for by the famous Krupp 6-pounder (3 kg) steel breech-loading cannons being issued to Prussian artillery batteries. Firing a contact-detonated shell, the Krupp gun had a longer range and a higher rate of fire than the French bronze muzzle loading cannon, which relied on faulty time fuses.

paragraph_text: Most automotive pistons have three rings: The top two, while also controlling oil, are primarily for compression sealing (compression rings).

At least two piston rings are found on most piston and cylinder combinations. Typical compression ring designs will have an essentially rectangular cross section or a keystone (right angled trapezoidal) cross section.

There are some taper - faced top rings as well, and on some old engines simple plain - faced rings were used.
