- Summary:
- Complex FEAD system in modern powertrain is reality today due to demanding regulation, hybrid powertrain and increasing customer expectation. Gasoline engines going to be preferred over diesel engines specially for passenger car application. Use of overrunning alternator pulley (OAP) is globally accepted as cost effective and technically proven product for FEAD system to make it robust by optimizing the system performance such as belt tension, hub load, slippage and vibrations to improve fuel consumption and to reduce engine emissions. Overrunning alternator pulley (OAP) is a mechanical device with one-way clutch unit which eliminates the torsional vibrations coming from engine crankshaft and ensures only accelerating proportions of crankshaft forces are transferred to alternator which means reduction in force level of belt drive system. This current paper will describe use of advanced overrunning alternator pulley in achieving improved fuel consumption and reduction in emissions, to make the FEAD system efficient over the rigid alternator pulley by eliminating the rotational irregularities coming from FEAD system. In this paper, we had simulated the various engine driving conditions to assess FEAD system performance in terms of hub load, belt pre-tension, belt slippage and vibrations by comparing rigid pulley and overrunning alternator pulley, followed by engine validation, which shows effectiveness of OAP
