In recent years, the world's largest democracies have recognized the threat posed by vehicle pollutants to our ecosystem, particularly the emission of hazardous gases. As a result, they have taken steps to tighten emission standards for motor vehicles in order to reduce toxicity. Additionally, the rapid urbanization taking place worldwide has led to increased consumption of petroleum products, such as diesel and petrol, which are derived from crude oil. Unfortunately, the reserves of crude oil are limited, and the availability of natural gas stocks is also restricted. Therefore, it is crucial to explore alternative sources of energy. This study focuses on examining the effects of using biodiesel as an additive in diesel engines (D.E) to observe its impact on various performance parameters such as noise emissions, break thermal efficiency, fuel consumption, carbon monoxide, and carbon dioxide. By comparing the effects of biodiesel blended fuels with conventional diesel fuel, we can analyze the behavior of diesel engines. The result shows the study indicate that the use of biodiesel as an additive reduces noise emission levels compared to diesel fuel. Additionally, the analysis of carbon monoxide and carbon dioxide emissions shows that biodiesel blended fuel results in lower carbon emissions when compared to traditional diesel fuel. These findings highlight the potential of biodiesel as a more environmentally friendly alternative in the context of diesel engines.

The use of biofuels to power compression–ignition engines makes it possible to reduce emissions of certain harmful components of exhaust gases. The purpose of this study was to determine the influence of second-generation biofuels on the course of indicator graphs and heat release characteristics of the Perkins 1104D-44TA compression–ignition engine. For comparative purposes, the same tests were carried out by feeding the engine with first-generation biofuel and diesel fuel. Babassu butyl esters (BBuE) were used as the second-generation biofuel. The second fuel was a first-generation biofuel—rapeseed oil methyl esters (RME). Analysis of the results made it possible to draw conclusions about the effect of using 2nd and 1st generation biofuels on the parameters of the combustion process. When the DF engine was powered, the lowest fuel dose per work cycle was obtained. In the case of RME and BBuE fuels, it depends on the engine load. For low loads, higher consumption is for RME, and for higher loads, fuel consumption for BBuE in-creases most often. This is due to the lower calorific value of the esters. The results of these tests indicate that feeding the engine with BBuE and RME fuel in most loads resulted in higher maximum combustion pressures compared to feeding the engine with DF which may be directly related to the higher cetane number of these fuels compared to DF and the oxygen content of these fuels. Feeding the engine with BBuE and RME esters compared to DF did not result in large differences in the maximum heat release rates HRmax. However, the values of the first and second maximum heat release rates x1max and x2max, in addition to the type of fuel, are strongly influenced by the operating conditions, especially the engine load. Analyzing the combustion angles of 5, 10, 50, and 90% of the fuel dose, it can be seen that feeding the engine with BBuE and RME esters for most measurement points results in faster combustion of the fuel dose compared to DF.

The use of biofuels is one way to reduce the increasingly visible harmful effects of diesel engines on the environment. At the same time, it is also a way to gradually reduce dependence on depleting oil resources. New sources for biodiesel production are currently being sought out. The authors of this article have produced esters from animal fat waste, obtaining a biofuel that can power diesel engines while obtaining a way to manage unnecessary waste. For this to be possible, it is necessary to confirm the possibility of using such biofuel to power compression ignition engines. To this end, it is moribund to conduct experimental tests on an engine dynamometer. The results of such studies made it possible to determine how such esters affect the parameters of the combustion process, which was the goal of the authors of this paper. In order to determine the effect of this biofuel on the parameters of the combustion process, indicator graphs of the pressure course in the engine cylinder were recorded. On their basis, heat release characteristics were drawn up and their most important indicators were determined. In addition, the parameters of the indicator charts were determined, such as the maximum pressure and the degree of its build-up during the combustion process. These tests were carried out on a Perkins 1104D-E44TA compression ignition engine, which is widely used in the construction industry as well as in agriculture. In order to be able to compare these results with diesel fuel, the same tests, under the same conditions, were carried out while feeding the engine with diesel fuel. It is worth noting that the tested esters were produced using a reactor designed and built by one of the co-authors of this publication. This reactor is used for the non-industrial production of biofuels from oils of various origins. Studies have shown that feeding the engine with esters results in an increase in the maximum fuel consumption of about 15%. This is dependent on the load and speed. Indicator graphs and their analysis indicated that feeding the engine with esters at lower loads results in higher maximum combustion pressures, depending on the engine load, compared to diesel fuel values by a maximum of about 10%. The calculated values of the degree of pressure increase during the combustion process showed that feeding the engine with esters at most loads results in an increase of up to 40% maximum. This is especially the case for a speed of 2200 rpm. In the case of parameters related to heat release characteristics, the relationship is the opposite, and feeding the engine with esters compared to diesel fuel results in higher maximum amounts and rates of heat release. These values are higher for esters from 20 to 40%. In addition, the percentage burnout of the fuel dose confirmed the information found in other publications that feeding the engine with biofuels causes faster combustion compared to diesel.
