Low Cost Catalytic Configurations for Mid-Range CNG Lean Burn Engines for BSIV Emission

This paper deals with the optimization of the catalytic convertor for CNG Lean burn Engine based on BS4 compliances. In addition to the present catalytic convertor the work is carried out for the optimization of catalytic convertor and also to meet the BS4 compliance and also to reduced cost for the same. In this project we have prepared the samples with some variation in the substrate with res...

Dynamic Optimization of Lean Burn Engine Aftertreatment

The competition to deliver fuel e cient and environmentally friendly vehicles is driving the 1 2 Submitted to Journal of Dynamics Systems, Measurement, & Control automotive industry to consider ever more complex powertrain systems. Adequate performance of these new highly interactive systems can no longer be obtained through traditional approaches, which are intensive in hardware use and nal co...

Dynamic Modeling of a Lean NOx Trap for Lean Burn Engine Control

A control oriented dynamic model of the Lean NOx Trap (LNT) behavior has been developed in SIMULINK. The model simulates the trapping and purging phenomena and includes the important parameters which affect the LNT behavior. These include the trap temperature, trapping and purging duration, air fuel ratios and the mass flow rates of the exhaust gases. Engine dynamometer test data have been used...
