Pump action

摘要

An innovative pump designed by UK engineers could lead to major improvements in the energy-efficiency of the oil systems used in diesel engines. Developed by Birmingham's Concentric, the new variable flow oil pump (VFP) is said to use significantly less power than conventional fixed flow pumps. Indeed, the pump has demonstrated savings for heavy-duty engines of between 3 and 4hp at rated speed and more than 1hp at cruise speed.
