“…It is seen from Figure 7 that increasing the engine load reduced HC emissions up to a specific load limit (75% load), with the trend reversing thereafter. This trend was also found by [42,67,68]. Increasing the engine load resulted in a richer mixture (lower AFR) within the combustion chamber and, therefore, a shorter ignition delay, corresponding to a reduced likelihood that the air-fuel mixture would be diluted by more air prior to autoignition.…”

Transportation is a vital necessity without which the entire world would come to a standstill. The fossil fuels used to power transportation are consumed at rates of approximately 100,000 times their rate of natural formation, and their consumption subjects the human environment and ecosystem to significant damage. As substitutes for fossil-based diesel, second-generation biodiesels can eliminate many of the challenges concerning first-generation biodiesels in terms of their high cost and the food versus fuel debate. The seeds of the date palm tree have significant oil content and are a promising prospective energy source. This study investigated the potential environmental benefits of this biofuel in terms of diesel tailpipe emission reduction. The various blends of palm date biodiesel were produced and matched to fuel standard requirements, resulting in four standard-compatible blends that were tested in a diesel engine at varying operating conditions for speed and load. Although the biodiesel emissions had lower concentrations of CO2, CO, and HC relative to fossil diesel, higher concentrations of NOx were detected. The results suggest that date-seed biodiesel could become a sustainable energy source for the transport sector, although further technical and economic investigations will be required before its wide deployment.

“…The tests verified the effect of biogas addition mainly on unit CO, NO, NO 2 , and PM emissions in the exhaust gases of the engine fueled by commercial diesel fuel and methyl esters of the used frying oil. It should be emphasized that in the studies of many authors [5,38,[61][62][63], the total amount of nitrogen oxides was investigated independently of the studied fuels and combustion systems. However, two of the most dangerous nitrogen oxides, NO and NO 2 , often occurring together, have been measured in the experimental studies-of which nitrogen dioxide is considered the most dangerous due to its impact on human health and other living organisms [59,60].…”

“…In such situations, a dual fuel combustion engine powering a generator [36,37] alternative, significantly limiting a farm's demand for energy from external sources and increasing level of independence of the indicated energy sources. Combustion engines are the main power source in transport [5,38]. Diesel engines in relation to spark-ignition engines are characterized by higher efficiency, associated with lower consumption of diesel fuel, [39][40][41] but higher PM and NOx emissions.…”

The aim of this study was to perform a comparative analysis of the unit gas emission value in the exhaust of a dual fuel diesel engine. The results of the effects of a diesel engine’s applications in biogas plants and the method for calculating mass gas emissions per unit of produced electricity are shown. The test was performed using a two-cylinder, naturally aspirated, liquid-cooled diesel engine. The diesel engine powered a generator connected to the grid. The engine was fed with liquid fuels—waste cooking oil methyl ester (UCOME) and diesel fuel (DF)—and with a gas fuel, biogas (BG). The engine ran at a constant rotational speed (2000 rpm ± 30 rpm) with variable load. The gas analyzer measured the amount of CO, NO, NO2, and PM (particulate matter) in exhaust gas. This gas content share was then converted to mass per engine generated energy unit. This experiment showed the effect of BG introduced to the intake manifold on fuel combustion, as well as an increase in CO and NO2 emission and decrease in NO and PM. In terms of dependence of exhaust emissions on the type of liquid fuel used, the use of UCOME as opposed to diesel fuel resulted in PM reduction and increase of NO emissions.

“…Advancement on biodiesel research has shown that mixing biodiesel with petro‐diesel would most likely solve technical challenges like fluid‐viscosity and other operational issues. Also, the use of additives (eg rapeseed oil methyl ester) can reduce the anthropogenic emissions from biodiesel engines .

Laboratory evidence of cyclic breaking in biodiesel products was recently reported. This study seeks to investigative biodiesel production from olive and soya biomass along recent scientific discovery. Research focus was on the analysis of mixed fossil‐biodiesel samples on diesel engine. The mixed blend of soya (B10 and B20) and olive (B10 and B20) were used in this study. The TD 200 diesel engine was used to examine the automobile implications of adopting olive and soya biodiesels for automobile applications. More so, the research seeks to know the effect of cyclic breaking on engine performance. Aside the normal parameters like torque, rotational speed, differential pressure, operational temperature, and power generated in the engine, five additional factors were considered that is sound of engine, power generated by engine in horse power, thermal efficiency, normal engine efficiency, and brake mean effect pressure. Most parameters show the effect of cyclic breaking in the mixed olive and soya biodiesel when the engine operates beyond 20 minutes. The temperature of the engine is increased by 41% and 29% for olive B10 and soya B10, respectively. The maximum engine efficiencies when pure diesel, Soya B10, and Olive B10 (at specific heat ratio of 8.5) were optimized was 0.44, 0.709, and 0.616, respectively. The shortcoming of the tested biodiesel products was highlighted in the research. The rate of cyclic breaking in biodiesel is recommended for further study.
