Effect of biodiesel fuels on diesel engine emissions
TL;DR: In this article, the authors collected and analyzed the body of work written mainly in scientific journals about diesel engine emissions when using biodiesel fuels as opposed to conventional diesel fuels, focusing on the most concerning emissions: nitric oxides and particulate matter.

Emissions from a diesel–bioethanol blend in an automotive diesel engine
TL;DR: In this article, an automotive engine using anhydrous bioethanol blended with conventional diesel, with 10% ethanol in volume and no additives, has been compared with those from pure diesel, and the results proved that the use of this renewable component provides a significant reduction on particulate emissions, with no substantial increase in other gaseous emissions.

Diagnosis of DI Diesel combustion from in-cylinder pressure signal by estimation of mean thermodynamic properties of the gas
TL;DR: In this paper, a thermodynamic approach, coherent with the mentioned species distinction, is also proposed, and the results of temperature correlations of the main thermodynamic properties are presented, as well as some results of the combustion diagnostic procedure from engine tests with different exhaust gas recirculation ratios.

Impact of fuel formulation on the nanostructure and reactivity of diesel soot
TL;DR: In this article, the impact of fuel formulation on diesel soot reactivity and nanostructure was investigated using a 2.5-liter, 4-cylinder, turbocharged, common rail, direct injection light-duty diesel engine.

Diesel emissions from biofuels derived from Spanish potential vegetable oils
TL;DR: In this paper, a stationary engine test bed, together with the instrumentation for chemical and morphological analysis, allowed to study the effect of these fuels on the engine emissions, soluble organic fraction of the particulate matter, origin of adsorbed hydrocarbons, sulphate content, particle number per unit filter surface, and mean particle diameter.
