- Abstract
- This paper shows an energetic analysis of a small diesel engine for micro-cogeneration applications at different
engine operating conditions. The aim is to evaluate the opportunity to perform cogeneration at different engine
speeds in order to strictly satisfy with the electrical demand while also providing heat from the engine. The
investigation was carried out on a prototype three-cylinder engine with 1000 cc of displacement. The engine
is equipped with a direct common-rail injection system that reaches a maximum pressure of 1400 bar. The
engine is provided with two emission reduction systems: a cooled EGR and an oxidation catalyst for the
reduction of NOx, and CO/HC emissions, respectively. Tests were carried out with conventional diesel fuel and
a biodiesel blend; in particular, a 20% v/v concentration of rapeseed methyl ester (RME) mixed with diesel fuel
was used. Combustion characteristics of the engine were analysed by means of both in-cylinder pressure and
rate of heat release traces. The heat recovery from the engine cooling water and from the exhaust gas was
calculated. Gaseous emissions were measured at the exhaust. A smoke meter was used to measure the
particulate matter concentration. The sizing and the counting of the particles were performed by means of an
engine exhaust particle sizer spectrometer. The results presented in this paper can be useful for the design of
more efficient and cleaner energy systems. It was found out that the adding of 20% v/v of RME to diesel fuel
does not affect significantly both the fuel conversion efficiency and the engine energetic flows. The adding of
20% v/v of RME to diesel fuel results in lower exhaust emissions. Nevertheless, at high engine speed, B20
emits larger particles because of the more advanced combustion with respect to diesel fuel. It can be argued
that the B20 combustion process can be optimized phasing properly the injection. (literal)
