Analysis of recoverable exhaust energy from a light-duty gasoline engine

Analysis of Recoverable Exhaust Energy from a Light-Duty Gasoline Engine

While EER (Exhaust Energy Recovery) has been widely pursued for improving the total efficiency and reducing CO2 emissions of internal combustion engines, the maximum regenerated power from the exhaust energy has been proposed and calculated in terms of endoreversible cycle. In this paper, based on the experimental data of an EER system installed on a light duty gasoline engine, the exhaust ener...

Impact of Methanol–Gasoline Fuel Blends on the Performance and Exhaust Emissions of a SI Engine

Feasibility Study of a Scroll Expander for Recycling Low-Pressure Exhaust Gas Energy from a Vehicle Gasoline Engine System

The growing number of vehicles on the road has led to a rapid increase in fuel consumption and toxic gas emissions, so the challenges in fuel efficiency improvement and reduction of CO2 and NOx emissions have always been on the top agenda of the automotive industry. The paper presents a feasibility study of recovering the low-pressure exhaust gas energy via by-pass connection of a scroll expand...

Measurements of ion concentration in gasoline and diesel engine exhaust

The nanoparticles formed in motor vehicle exhaust have received increasing attention due to their potential adverse health effects. It has been recently proposed that combustion-generated ions may play a critical role in the formation of these volatile nanoparticles. In this paper, we design an experiment to measure the total ion concentration in motor vehicle engine exhaust, and report some pr...

Methods of characterizing the distribution of exhaust emissions from light-duty, gasoline-powered motor vehicles in the U.S. fleet.

Mobile sources significantly contribute to ambient concentrations of airborne particulate matter (PM). Source apportionment studies for PM10 (PM < or = 10 microm in aerodynamic diameter) and PM2.5 (PM < or = 2.5 microm in aerodynamic diameter) indicate that mobile sources can be responsible for over half of the ambient PM measured in an urban area. Recent source apportionment studies attempted ...
