Heavy-Duty Engine Emissions: Response

The effect of hydrogen and nitrogen addition on heavy duty diesel engine emissions under reactivity controlled compression ignition combustion

The aim of this study is to evaluate a heavy duty diesel engine operation under reactivity controlled compression ignition combustion fueled with diesel oil and natural gas enriched with hydrogen and nitrogen addition. In this study, a single cylinder heavy– duty diesel engine is set to operate at 9.4bar gross IMEP (Mid- Load). The amount of injected diesel oil per cycle into the engine combust...

Neural Network Modeling of the Emissions and Performance of a Heavy-Duty Diesel Engine

SYNOPSIS Internal combustion engines are being required to comply with increasingly stringent government exhaust emissions regulations. Compression ignition piston engines will continue to be used in cost-sensitive fuel applications such as in heavy-duty buses and trucks, power generation, locomotives, and off-highway applications, and will find application in hybrid electric vehicles. Close co...

A Fuel-Based Inventory for Heavy-Duty Diesel Truck Emissions

A fuel-based method for estimating heavy-duty diesel truck emissions is described. In this method, emission factors are normalized to fuel consumption; vehicle activity is measured by the amount of diesel fuel consumed. For the San Francisco Bay Area during summer 1996, on-road heavy-duty diesel trucks were estimated at the upper bound to emit 110 × 103 kg/day of nitrogen oxides (NOx) and 3.7 ×...
