“…Dual fuel mode of operation utilizes a high cetane, easy to ignite pilot fuel to combust a low cetane primary fuel such as natural gas, biogas, propane, etc. [18]. Biogas is a potentially renewable fuel, producible by cheap and environment friendly methods.…”

“…It is notable that for all loads in the dual fuel mode the values of NO x are much lower than for the single fuel operation. This is due to the fact that at around 30 % of the pilot fuel injected, the amount of pilot fuel decreases, and thus the jet becomes progressively smaller [18]. Also, the introduction of biogas increases the specific heat capacity of the fuel mixture, which thereby slows the flame propagation and consequently the production of NO x emissions is reduced [34,35,36].…”

This study is an attempt at achieving diesel fuel equivalent performance from diesel engines with maximum substitution of diesel with renewable fuels. In this context the study has been designed to analyze the influence of B20 algae biodiesel as a pilot fuel in a biodiesel biogas dual fuel engine, and results are compared to those of biodiesel and diesel operation at identical engine settings. Experiments were performed at various loads from 0 to 100 % of maximum load at a constant speed of 1500 rpm. In general, B20 algae biodiesel is compatible with diesel in terms of performance and combustion characteristics. Dual fuel mode operation displays lower thermal efficiency and higher fuel consumption than for other fuel modes of the test run across the range of engine loads. Dual fuel mode displayed lower emissions of NOx and Smoke opacity while HC and CO concentrations were considerably higher as compared to other fuels. In dual fuel mode peak pressure and heat release rate were slightly higher compared to diesel and biodiesel mode of operation for all engine loads.

“…Worldwide, in recent years, many drastic measures for reduction of pollutant emissions with negative effects on health and the environment have been imposed. Many research programs have been developed to study the possibilities for reducing of the pollutant emissions from combustion gases and of new control technologies of pollutant emissions, [3], [4], [5], [6], [7], [8], [9], [10].…”

The progressive diminution of the oil reserves all over the world highlights the necessity of using alternative fuels derived from durable renewable resource. The use of the alternative fuels represents a viable solution to reduce the pollutant emissions and to replace fossil fuels. Thus, a viable solution is the use of the animal fats in mixture with the diesel fuel at the diesel engines. A D2156 MTN8 diesel engine was firstly fuelled with diesel fuel and then with different blends of diesel fuel-animal fats (5% and 10% animal fats content). In the paper are presented some results of the experimental investigations of engine fuelled with preheated animal fats. The raw animal fats effects on the combustion process and on the pollutant emissions at different engine loads and 1450 rev/min engine speed are showed. The engine cycle variability increases at the animal fats content increase. The cycle variability for maximum pressure, maximum pressure angle and indicated mean effective pressure is analysed. The cycle variability coefficients values don’t exceed the recommended values of the standard diesel engine.

“…Surawski [3] shows that the use of LPG leads to the pre-mixed combustion of LPG-air mixture followed by the in-cylinder maximum pressure and pressure rise rate increase. Polk [4] limits to maximum the propane substitutions so the NO X and smoke emissions decrease. Boretti [5] converts a heavy duty truck diesel engine to operate with diesel fuel-LPG, showing the reduction of particulate and CO 2 emissions.…”

Study of the cycle variability at an automotive diesel engine fuelled with LPG

Abstract. Liquid Petroleum Gas is a viable alternative fuel for diesel engines due to its ability of emissions and fuel consumption reduction. Combustion variability at LPG diesel engine is analysed for maximum pressure, maximum pressure angle and indicated mean effective pressure. Combustion variability is influenced by the increase of LPG cycle dose which lead to the increase of the cycle variability coefficients values, but without exceeding the admitted values that provide diesel engine reliability. Analysis of COV values establishes the maximum admitted values of LPG cycle.
