This study examined the performance and emission characteristics of a household size trigeneration based on a diesel engine generator fuelled with hydrogen comparing to that of single generation, cogeneration using ECLIPSE simulation software. In single generation simulation, the engine genset...

A biofuel micro trigeneration prototype has been developed to utilise local energy crop oils as fuel in rural areas and developing countries. Straight plant oils (SPOs) only leave behind very little carbon footprint during its simply production process compared to commercial biodiesels in...

This paper presents a comparison of a high-temperature heat pump and an organic Rankine cycle (ORC) plant for the recovery of low-grade waste heat for a UK inorganic chemicals case study. Superficially, the two technologies appear equally suitable for use here; therefore, both technologies are...

In this paper, an exergy cost analysis method based on the structural theory of thermoeconomics is applied to a gas-fired micro-trigeneration system, which uses a small-scale generator set driven by a gas engine and a new small-scale adsorption chiller (ADC). The thermoeconomic model for the...

A conceptual analysis of the mechanism of the Miller cycle for reducing NOx emissions is presented. Two versions of selected Miller cycle (1 and 2) were designed and realized on a Rover "K" series 16-valve twin-camshaft petrol engine. The test results showed that the application of the Miller...
