| 释义 |
The Lempor ejector is a steam locomotive exhaust system developed by noted Argentine locomotive engineer Livio Dante Porta. The name is a combination of those of Maurice Lemaître, Belgian locomotive engineer, and Porta. OperationIn a steam locomotive, draft is produced in the firebox by exhausting the steam coming from the cylinders out of the chimney, or also by a blower. The Lempor ejector ejects differently from the conventional blastpipe; as one cylinder ejects it creates a vacuum in the other cylinder, thereby requiring less power to drive the piston. ResultsThe Lempor exhaust is claimed to deliver a 100% improvement in draughting capacity over traditional exhaust systems and a 40% increase in ejector performance.[1]{{Citation needed|date=January 2010}} References1. ^http://www.trainweb.org/tusp/lempor/lempor_theory.html External links
