Description
Pistons - VESPA Nose piston- Vespa 150cc VL1T, VL2T, VL3T, VB1T
Replacement piston for the 150cc cylinders of Vespa models VL1T, VL2T, VL3T, VB1T - 57.4mm is the 2nd oversize. Nose pistons are used in cross-flow scavenged two-stroke engines to keep the fresh gas flow away from the open exhaust. The nose sits on the piston crown and deflects the gas flow upward. The inlet cross-section can be larger than in cross-flow scavenged engines with flat pistons. Nose pistons also cannot prevent fresh gas from escaping into the exhaust at all loads and speeds, and they cause an unfavorable combustion chamber shape. After reverse scavenging was developed in the 1920s, cross scavenged engines became less important.
