Problems solved by technology

The engine draws the same volume of air-fuel mixture as a naturally aspirated engine, but due to the higher pressure and therefore higher density, more air and fuel mass is supplied to the combustion chamber in a controlled manner

Abstract

An axial compressor (30) is disposed upstream of the compressor wheel (16) and is mountable in the inlet duct (32) of the compressor housing (26) of the turbocharger (10). An axial compressor (30) can increase the pressure ratio by about 1.3. The axial compressor (30) may be driven by a motor (40), such as a magnetic stepper motor, a servo motor, and a squirrel cage motor. The axial compressor can have a fan (34), wherein the boost pressure can be controlled by the rotation speed of the fan (34), which can be accelerated or decelerated according to the usage status. A magnetic stepper motor (40) can drive a fan (34) having a fan wheel (36) with a magnet (44) associated with an energizable coil (42) that produces a magnet (44) that can following the rotating magnetic field.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and all benefit of US Provisional Application 61 / 894,955, filed October 24, 2013, entitled "Axial Compressor with Magnetic Stepper or Servo Motor." [0003] field of invention [0004] The invention relates to a turbocharger with an axial compressor driven by a motor. More specifically, the present invention relates to an axial compressor that increases the pressure ratio upstream of the compressor wheel of a turbocharger. Background technique [0005] The benefits of turbocharging include increased power output, lower fuel consumption, reduced pollutant emissions, and improved transient response. Turbocharging of engines is no longer viewed primarily from a high power performance point of view, but is seen as a 2 ) emissions to reduce fuel consumption and environmental pollution. Currently, the main reason for turbocharging is to use exhaust energy to reduce fuel consumption and emis...
