Q: Is a piston a component of reciprocating engines? ¶
A: Yes, and reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms.
Q: Is a piston a piston for a petrol engine that has been reduced in size and weight as much as possible? ¶
Q: Are pistons nearly always comparatively thin discs: their diameter is several times their thickness? ¶
Q: Were pistons of cast iron? ¶
A: Yes, but there were obvious benefits for engine balancing if a lighter alloy could be used.
Q: Are pistons cast from aluminium alloys? ¶
Q: Are pistons used in two-stroke engines with crankcase compression? ¶
A: Yes, where the gas flow within the cylinder must be carefully directed in order to provide efficient scavenging.
Q: Is a piston responsible for gas sealing and carries the piston rings? ¶
Q: Are pistons long relative to their diameter? ¶
Q: Are pistons single-acting? ¶
Q: Is a piston purely a mechanical guide? ¶
