This study investigated the effects of palm oil methyl ester biodiesel blends on a common rail passenger car engine in terms of performance, oxides of nitrogen (NOx) and smoke emissions. Up to 40% biodiesel blend was used in this study. As expected, running on biodiesel reduces full load torque and power. The fuel consumption increased up to 10%, particularly at part loads. On the other hand, the thermal efficiency only exhibit small difference between the fuels. As much as 46% reduction in smoke emissions was observed at 40% biodiesel content. The NOx emission was shown to be slightly increased under certain operating conditions at part loads, while showing reduction at other conditions. In general, biodiesel showed more significant effects on the performance and emissions at part load conditions. Thus, low and medium speed/load region was proposed as an area where improvement by injection strategies optimization can be made.

In this study, the performance and emission of a thermal barrier coating (TBC) engine which applied palm oil biodiesel and diesel as a fuel were evaluated. TBC was prepared by using a series of mixture consisting different blend ratio of yttria stabilized zirconia (Y2O3·ZrO2) and aluminum oxide-silicon oxide (Al2O3·SiO2) via plasma spray coating technique. The experimental results showed that mixture of TBC with 60% Y2O3·ZrO2 + 40% Al2O3·SiO2 had an excellent nitrogen oxide (NO), carbon monoxide (CO), carbon dioxide (CO2), and unburned hydrocarbon (HC) reductions compared to other blend-coated pistons. The finding also indicated that coating mixture 50% Y2O3·ZrO2 + 50% Al2O3·SiO2 had the highest brake thermal efficiency (BTE) and lowest of brake specific fuel consumption (BSFC) compared to all mixture coating. Reductions of HC and CO emissions were also recorded for 60% Y2O3·ZrO2 + 40% Al2O3·SiO2 and 50% Y2O3·ZrO2 + 50% Al2O3·SiO2 coatings. These encouraging findings had further proven the significance of TBC in enhancing the engine performance and emission reductions operated with different types of fuel.

Smoke Opacity

A hydrocarbon fuel extracted from waste high-density polyethylene (WHDPE) by catalytic pyrolysis in a batch scale reactor is blended with diesel by 30% vol. (called as D70H30) is tested in a variable compression ratio engine equipped with a common rail system. Experiments were conducted at three compression ratios (16:1, 17.5:1, and 19:1) and exhaust gas re-circulation (EGR) rates (0%, 10%, and 20%) at the engine’s rated power to evaluate its combustion, performance and emission characteristics. The results revealed that, increasing the compression ratio resulted in higher peak cylinder pressure (PCP) and heat release rates (HRR). Introduction of EGR diminished both PCP and HRR peaks. The brake thermal efficiency of D70H30 blend was 4% lower than diesel at same operating conditions which got better at higher compression ratio without EGR. NOx emission was highest when injected at compression ratio 19:1 and at 0% EGR rate which was 6% and 3% higher than diesel and D70H30 blend operated at engine stock settings. In comparison with baseline diesel smoke opacity remained lower at all operating conditions, where lowest smoke emission was recorded at CR19 and at 0% EGR rate. UHC and CO emission followed the similar trend of smoke opacity. Whereas CO2 emission increased with compression ratio and reduced with induction of EGR. It can be concluded from the study that at higher compression ratio and low EGR rates D70H30 blend can be effectively utilized in a CRDi engine.

The main purposes of this research were to study the diesel engines' performance and emission characteristics of quaternary fuels, as well as to analyze their tribological properties. The quaternary comprised waste plastic pyrolysis oil, waste cooking oil biodiesel, palm oil biodiesel, and commercial diesel. Their compositions were analyzed by gas chromatography and mass spectrometry. By using mechanical stirring, four quaternary fuels with different compositions were prepared. Because Malaysia is expected to implement B30 (30% palm oil biodiesel content in diesel) in 2025, B30a (30% palm oil biodiesel and 70% commercial diesel) mixture was prepared as a reference fuel. In total, 5%, 10%, and 15% of each waste plastic pyrolysis oil and waste cooking oil biodiesel were mixed with palm oil biodiesel –commercial diesel mixture to improve fuel characteristics, engine performance, and emission parameters. The palm oil biodiesel of the quaternary fuel mixture was kept constant at 10%. The results were compared with B30a fuel and B10 (10% for palm oil biodiesel and 90% for diesel; commercial diesel). The findings indicated that compared with B30a fuel, the brake power and brake thermal efficiency of all quaternary fuel mixtures were increased by up to 2.78% and 9.81%, respectively. Compared with B30a, all quaternary fuels also showed up to a 6.31% reduction in brake-specific fuel consumption. Compared with B30a, the maximum carbon monoxide and carbon dioxide emissions of B40 (60% commercial diesel, 10% palm oil biodiesel, 15% waste plastic pyrolysis oil and 15% waste cooking oil biodiesel) quaternary fuel were reduced by 19.66% and 4.16%, respectively. The B20 (80% commercial diesel, 10% palm oil biodiesel, 5% waste plastic pyrolysis oil and 5% waste cooking oil biodiesel) quaternary blend showed a maximum reduction of 41.86% in hydrocarbon emissions collated to B30a. Compared with B10, the average coefficient of friction of the quaternary fuel mixture of B40, B30b (70% commercial diesel, 10% palm oil biodiesel, 10% waste plastic pyrolysis oil and 10% waste cooking oil biodiesel), and B20 were reduced by 3.01%, 1.20%, and 0.23%, respectively. Therefore, the quaternary blends show excellent utilization potential in diesel engine performance.

Palm oil methyl ester (POME) produced from crude palm oil have some excellent properties which makes it a feasible alternative to diesel fuel. However, its higher oxygen content makes it nitrogen oxide emission prone when burned in diesel engines. This problem can be resolved by emulsifying POME with distilled water in the presence of suitable surfactant. Two phase water in oil emulsion is prepared by using ultrasonic bath sonication. SPAN 80, a lipophilic surfactant is used for 1% by volume to prepare the emulsion. Water quantity in the emulsion is varied by 5% and 10% by volume and stability study is performed. It is found that emulsion with 5% water is more stable. Thereafter, POME emulsion samples are prepared with 5% water and tested in a variable compression ratio diesel engine. The performance and emission characteristics are investigated for a set of loads and compression ratios (CR). The experimental observations show that 5% water in POME produce 3.5% lower brake thermal efficiency and 11% higher brake specific fuel consumption as compared to baseline diesel. Furthermore, the exhaust gas temperature and other emissions like oxides of carbon, oxides of nitrogen and hydrocarbon for the emulsified POME are found to be lower than the baseline diesel.

Palm Oil Biodiesel

This study describes the effects of palm oil biodiesel blended with diesel on the combustion performance, emission characteristics, and soot morphology in a 4-cylinder common-rail direct-injection (CRDI) diesel engine. The operational condition is idle speed, 750 rpm (the lowest speed of the test engine without any operation by driver), and the load conditions of the engine are 0 Nm and 40 Nm. Five kinds of biodiesel fuels are blended with diesel in 0%, 10%, 20%, 30%, and 100% proportions by volume. A pilot injection was applied at BTDC 15 °CA and 20 °CA. Part of the pilot injection affects the combustion of the main injection due to the deterioration of the spray because of the high viscosity of palm oil biodiesel. Palm oil biodiesel is sufficient to keep the engine stable in an idling state, but the fuel economy deteriorated. The deterioration of the spray due to the high viscosity of palm oil biodiesel is offset by the effect of oxygen content and high cetane number, resulting in a constant nitric oxide (NOx) emission. However, particulate matter (PM) is reduced. When the engine load is increased, the carbon monoxide (CO) emission amount increased because of the insufficient intake air and oxygen content to reduce the fuel-rich areas. However, when the palm oil biodiesel blend ratio was above a certain level, the influence of oxygen content in the palm oil biodiesel increased, resulting in reduced CO emission levels. Hydrocarbon (HC) was reduced by oxygen atoms in palm oil biodiesel. The sizes of particulates emitted from diesel engine using palm oil biodiesel decreased with an increased blend ratio because of oxidization of hydrocarbons absorbed on PM.

Engine Control System

This study investigated the effects of palm oil methyl ester blends on a common rail passenger car engine in terms of changes in the fuel system response. Up to 40% biodiesel blend was used in this study. Operating on biodiesel causes the engine control system to modify the injection parameters by increasing the injection pressure and duration while advancing the start of injection timing for the same power output. This engine control system-response to biodiesel is due to the inherent low energy density of biodiesel. Low and medium speed/load region was proposed as an area where improvement by injection strategies optimization can be made.

Biodiesel has been immersed as an immediate alternative of fossil fuels for diesel engines. However, choosing a good combination of biodiesel blends based on both performance and emission depend on various factors. The chapter presents the modeling and optimization of performance and emissions parameters of a biodiesel-run diesel engine using an integrated MCDM approach. The integrated MCDM approach consists of entropy with MCRA method. An experimental case study on performance and emission study of diesel engine is considered to show the modeling capability of the proposed method. The results show that trail no. 4 yields the optimal setting compare to the other combinations. The trail no. 4 gives optimum operating condition such as 85-90% load and PB10 which provides optimum performance parameters like higher brake thermal efficiency (BTE), lower brake-specific energy consumption (BSEC), lower carbon monoxide (CO), lower hydro carbon (HC), and lower oxides of nitrogen (NOx), respectively.
