This paper addresses the physicochemical characteristics of petroleum based diesel, coal based diesel and blended diesel (volume ratio of petroleum based diesel and coal based diesel 1:1), the power performance, fuel economy and exhaust emission with the three kinds of fuel were investigated on an engine test bench. The results show that: without any change in the diesel engine, when the engine fueled with coal based diesel power slightly upgraded, fuel consumption rate change little, exhaust smoke decrease obviously compared with using petroleum based diesel, that means coal based diesel is a kind of low-pollution alternative fuel for diesel engine.

The physicochemical characteristics of a new composite oxygenated fuel named oligomeric polyoxymethylene dimethyl ether and DMM10 (the blend of this fuel and conventional diesel oil with 10% in volume) were analyzed. The power performance, fuel economy, combustion characteristics and exhaust gas emission of a four strokes, direct injection, turbocharged and intercooled diesel engine fuelled with DMM10 and diesel fuel were analyzed and compared. The results show that in comparison to original diesel engine, when the engine fuelled with DMM10 blend fuel, the power performance remains unchanged; BSEC decrease slightly, smoke emission decreases obviously and its decrease rate is up to 72%.

Biodiesel Blend

The main purpose of this research is to study the effect of various blends of an environmental friendly alternative fuel “methyl ester” on the performance of a heavy diesel engine. The biodiesel was obtained from a chemical process: the transesterification of waste oils (frying oils). Tests were conducted on an engine test bench in accordance to DIN 2020 standards. Results obtained demonstrate that the biodiesel gives very interesting ecological advantages but engine performance was reduced slightly comparatively to those obtained with a pure diesel fuel. We have noted about 5% decrease in power and torque and about 2% in Nox emission for every 10% of biodiesel blend added comparatively to pure diesel. However, the use of biodiesel has slightly increased specific fuel consumption (about 6% for every 10% of biodiesel blend added).

The problems facing the world, in relation to the increasing consumption of petroleum and its limited sources, as well as pollution by fuel-related gases, such as CO, have sparked research on the application of biogasoline as an environmentally friendly alternative fuel. Our research aimed to determine engine performance through mixtures of biogasoline and gasoline to measure torque, power, and fuel consumption rate, and to determine the effect of the mixture on the level of air pollution. The biogasoline used was previously prepared from cooking oil through a Cr-zeolite-catalyzed process. The testing methods on the fuel mixture as a working substance included engine performance and exhaust emission tests, applied to four-stroke engines with mixtures with gasoline and biogasoline ratios of 95:5, 90:10, and 85:15. The engine performance test results showed that the highest values of torque, power, and average effective pressure were of the fuel with a composition of 85:15. CO and HC, the two emitted gases with high toxicities, based on the air quality standard, should not be more than 5.5% by volume and 2400 ppm, respectively. In this research, the findings indicated that both substances, not exceeding 3.0% by volume and not more than 200 ppm, respectively, are safe and environmentally friendly.

AbstractHybridization of the drive train in commercial vehicles is a key solution toward meeting the strict future requirements to reduce carbon dioxide emissions within the European Union. In order to decrease fleet consumption a large number of different hybrid systems are already available in series in the passenger car sector. Due to the cheap and powerful 48 volt hybrid components and the lower hazard potential compared to high voltage, future commercial vehicles could also benefit from the 48V technology and contribute to lower fleet fuel consumption. Therefore, a complete 48V mild hybrid system was built on the diesel engine test bench as part of a research project. This paper highlights the utilization of a powerful 48V-motor to propel the coolant pump on a diesel engine of the 13-L commercial vehicle class. Three different drive variants of the coolant pump were implemented and measured on the diesel engine test bench. MATLAB®/Simulink®-simulations were conducted to assess the possible fuel savings in three different driving cycles. This paper provides a summary and interpretation of the measurement and simulation results. The simulation studies predict a decrease of fuel consumption of up to 0.94%. Furthermore, the additional advantages of electrified coolant pumps based on 48V are discussed.

Dosing Strategy

Urea dosing strategy for SCR is studied for a diesel engine fuelled with bio-diesel BD20. Bio-diesel BD20 is consisted of biofuels made from waste cooking oil and national V diesel, and biofuels accounts for 20% by volume. The results show that, bio-diesel engine torque decreases by a maximum of 0.55%, brake fuel consumption rate increases by a maximum of 0.53% ,when the urea dosing strategy is adjusted and the engine and SCR are not changed. ESC tests show that, the maximum of NOXconversion ratio is 95%, the minimum is 57%, and the average value is 74% under ESC 12 conditions except idling, the maximum of HC decrease ratio is 74%, the minimum is 35%, and the average value is 55%, when the urea is dosed. NOXemission is 1.55 g/(kW·h) in ESC test, NOXemission is 2 g/(kW·h) in ETC test, and NH3slip is lower than 10×10-6, which proves that the NOXemission from the engine fuelled with BD20 can meet national emission standards V by adjusting the urea dosing strategy.

To meet stringent exhaust emission norms worldwide, various exhaust pre-treatment and post-treatment techniques have been employed in modern engines. Using antioxidant additives in biodiesel fuels is a promising and effective NOx reduction technology. Non-edible jatropha oil based methyl ester was produced and blended with conventional diesel. Five fuel samples (Diesel, JB5, JB5DPPD0.15%, JB15 and JB15DPPD0.15%) were tested for their use as substitute fuel for a radiator-cooled four cylinder diesel engine. Experiment results show that DPPD antioxidant additive could be reduced NOx emission significantly with slight penalty on engine performance as well as CO and HC emission. However, when compared to diesel combustion the emissions of HC and CO were found nearly same or below. By addition of 0.15% (m) DPPD additive in JB5 and JB15 reduction of NOx emission were 12.68% and 13.36 % compared to biodiesel blends without additive at full throttle position. As conclusion, JB5 and JB15 with addition of 0.15% (m) can be used in four cylinder diesel engine to reduce NOx and consequently overcome the barrier to market expansion of biodiesel fuels.

Abstract This paper investigates the operating characteristics of an off-road diesel engine to enhance its power performance in plateau. First, the impacts of altitude on the power, fuel economy, and emissions characteristics were analyzed by a bench test. Second, the combustion and overall performance working at different altitudes were studied by three-dimensional numerical simulation, including the relationship between fuel injection parameters and engine performance. The results showed that altitude significantly affects the performance of the off-road diesel engine. As the altitude increased from 0 m to 2000 m, the engine power decreased as much as 4.3%, and the brake-specific fuel consumption (BSFC) increased as much as 6%. At the peak torque condition, the intake manifold boost pressure and the exhaust manifold pressure both reduced with a rise of altitude, while the intake and exhaust manifold temperatures both increased with a rise of altitude. Finally, after comparing the in-cylinder flow conditions and combustion characteristics given by six combustion chamber designs that have different shrinkage ratios, the engine performance at 4000 m altitude with five different fuel spray angles were further optimized. The engine rated power increased by 8.2% when the shrinkage ratio was 7.28% and the fuel spray angle was 150 deg at the 4000 m altitude.
