Cassava biogasoline was tested on electronic fuel injection vehicles in urban traffic conditions with varying engine load. Biogasoline tested includes B0, B10, B20, and B30. The engine speed was operated within 750 to 1800 rpm (low-speed range) to simulate urban traffic condition. The engine load was varied through the operation of air conditioner (AC). Fuel consumption was measured in real terms (ml/s) and CO emissions were measured with the Hesbon HG 520 Engine Gas Analyzer (EGA) in the percentage of total exhaust gas. The results showed that B10 has the lowest fuel consumption of 0.24 ml/s in conditions without AC and 0.41 ml/s with AC. Meanwhile, CO emissions tend to be constant with change in the proportion of cassava biogasoline and increased with additional AC load.

Tis paper provides an overview of possibilities for determining tractor’s engine load, fuel consumption and exhaust emissions in real operating conditions. Theuse of accumulated database in tractor’s electronic control modules for the analysis of engine load, fuel consumption and exhaust emissions is analysed. The methodology for analysis of engine power, speed and exhaust emissions’ dependencies, also for analysis of engine exhaust emissions is presented. Tis paper presents testing results of the unit combined of tractor “Massey Ferguson MF 6499” and drilling machine “Vaderstad Rapid” by engine load, fuel consumption and exhaust emissions. Drilling process time, engine load, fuel consumption and exhaust emission components’ distribution are presented in different engine speed and cyclic fuel injection modes. Test results are analysed separately for technological drilling and work processes at the headland. In the technological process of drilling, if the tractor engine speed and, correspondingly, the transmission gear ratio were reduced to get the set working speed, fuel consumption decreased, CO and CO2 emissions varied slightly, but the NOx increased significantly. Significant part of exhaust emissions occurred at headlands. The conclusion is that the fuel consumption and exhaust emissions, including harmful components, can be reduced only by complex optimization of technological processes and tractor operating modes.

Fuel Consumption And Emissions

This paper presents gain scheduling of control strategy for parallel hybrid electric vehicles based on the traffic condition. Electric assist control strategy (EACS) is employed with different parameters for different traffic conditions. The parameters of the EACS are optimized and scheduled for different traffic conditions of TEH-CAR driving cycle. TEH-CAR is a driving cycle which is developed based on the experimental data collected from the real traffic condition in the city of Tehran. The objective of the optimization is to minimize the fuel consumption and emissions over the driving cycle, while enhancing or maintaining the driving performance characteristics of the vehicle. Genetic algorithm (GA) is used to solve the optimization problem and the constraints are handled by using penalty functions. The results from the computer simulation show the effectiveness of the approach and reduction in fuel consumption and emissions, while ensuring that the vehicle performance is not sacrificed.

The objective of this paper is to find experimentally the suitable working conditions of a pressure wave supercharger (PWS) for SI engine. A belt-driven CVT was installed in order to drive the rotor of PWS to the appropriate speed regardless of engine speed. The maximum BMEP was achieved by changing speed of the PWS rotor at constant engine speed and throttle open ratio. From the experiment, the appropriate rotor speeds which led to maximum BMEP at every engine speed and throttle open ratio were achieved. The results showed that two power peaks existed during the range of the tested rotor speed. Since the drop in BMEP between these two power peaks was relatively small, the rotor speed range between these points was defined as effective rotor speed. At engine speed of 2000–4000rpm, the effective rotor speed was found at the engine-rotor ratio of 2.5. In addition, the maximum compression efficiency of PWS was 75% at engine speed of 3000rpm and the exhaust gas pressure reduced to the same level of commonly used turbochargers at all engine speed. Furthermore, results of the transient experiment showed that PWS had as good response as the small turbocharger, which was optimized for the tested engine.

In the present scenario, the designs of S I engine being used in automotives by various manufacturers are not properly suitable to Indian climate condition. India is among those tropical countries where the variation in the temperature is having very vast range i.e. from 0°C to 50°C in various regions of the country. Looking in to this vast varying temperature range, it is very difficult to say that which temperature is most suited for operating condition of engines and will give the best performance levels as far as SFC & BP is concerned. In this work, it has been tried to investigate the best option to run the SI engine and simultaneously to maintain the emission norms. Today research and development in the field of gasoline engines have to face double challenge; on one hand, fuel consumption has to be reduced, while on the other hand, even more stringent emission standard have to be fulfilled. The development of engines with its complexity of in-cylinder process requires modern developed tools to exploit the full potential in order to reduce fuel consumption. There are many strategies for improving fuel economy and reducing exhaust emission HC & CO. The experimental study is carried out on a three cylinders, four stroke, petrol, carbureted, water cooled engine test rig connected to eddy current type dynamometer. The objective of this work was to examine engine performance parameter i.e. specific fuel consumption (SFC), brake power (BP) and also exhaust emission on Varying Engine Temperature at 50, 60, 70, 80° C and at an engine speed of 1500, 2000, 2500 rpm with respect to engine load 6, 9, 12 kg. The results are shown by various graphs with effect of engine temperature on specific fuel consumption, brake power, engine speed, engine load and emission levels of Nox, HC, CO for gasoline and LPG to improve fuel consumption.

Engine Power

Tractor load influences engine work parameters having an influence on the working economy and productivity of the complete tractor aggregate. The operational economy and productivity of the tractor is mostly evident when its engine power is utilized at least at 80% and engine speed is as low as possible. The paper analyses the engine parameters of tractor Massey Ferguson MF 8480 during the operational period of road construction works. Control tests on the parameters of the engine load of the tractor engine in combination with the employed milling equipment WS 2500 produced by the company ‘Wirtgen’ were performed. The study was carried out using engine load tables and graphs collected and stored in the so called ECU Load Profileintegrated in Electronic Engine Control Units. Theoretical analysis was made and an equation presented to establish the relation between engine power, engine speed and the quantities of cyclic fuel consumption. The study results present the distribution graphs of work time and fuel consumption at different engine speed during the operational period. The paper also indicates engine load and fuel consumption graphs of the tractor in combination with milling equipment. The article has also disclosed that the analysis of engine speed and load modes using information obtained from tractor‐integrated digital microprocessors reveals the operation quality of the tractor.

The crude oil based fuel price is constantly increasing in India, So it is compulsory to utilize the fuel properly by the user. As most of the driver tends to press the gas pedal unnecessarily, the fuel used at that particular condition is excess than the requirement. This experiment focuses on improving the fuel economy by warning the driver to drive their vehicles in optimum Specific Fuel Consumption (SFC) range using electronic SFC Speed Range Indicator. In variable speed Internal Combustion Engines there will be an optimum SFC range for a particular load and Engine Speed. Our system will monitor the Engine speed and load continuously and also compare the values with best SFC speed range graph and depends on these values the three Light Emitting Diode (LED) on Specific Fuel Consumption Speed Range Indicator(SFCSRI) will glow accordingly to mention the driver about the optimum, low or high speed. This helps the driver to drive their vehicles on optimum SFC range

Traffic Conditions

The identification and analysis of the spatiotemporal dynamic traffic patterns in citywide road networks constitute a crucial process for complex traffic management and control. However, city-scale and synchronal traffic data pose challenges for such kind of quantification, especially during peak hours. Traditional studies rely on data from road-based detectors or multiple communication systems, which are limited in not only access but also coverage. To avoid these limitations, we introduce real-time, traffic condition digital maps as our input. The digital maps keep spatiotemporal urban traffic information in nature and are open to access. Their pixel colors represent traffic conditions on corresponding road segments. We propose a stacked convolutional autoencoder-based method to extract a low-dimension feature vector for each input. We compute and analyze the distances between vectors. The statistical results show different traffic patterns during given periods. With the actual data of Chongqing city, we compare the feature extraction performance between our proposed method and histogram. The result shows our proposed method can extract spatiotemporal features better. For the same data set, there is little difference in the number distribution of red pixels found in the statistics result of the histogram, while differences do exist in the results of our proposed method. We find the most fluctuated morning is on Friday; the most fluctuated evening is on Tuesday; and the most stable evening is on Wednesday. The distance captured by our method can represent the evolution of different traffic conditions during the morning and evening peak hours. Our proposed method provides managers with assistance to sense the dynamics of citywide traffic conditions in quantity.

The Impact

In order to simulate the impact of increased shipping activities to the arctic environment for a scenario with decreasing ice extent and ice volume, a simulation tool for ship travelling time was enhanced with regard to the determination of fuel consumption and exhaust emission on the Northern Sea Route (NSR). The tool was then used to investigate the impact of ships in different periods within the years 2000 and 2007 with various ice conditions. The transit speed is compared for different periods in the past and present by using ice records from different years together with route parameters and ship data as input for a simulation program. The program is able to calculate the ship resistance in open water and additional components due to wind, waves and ice within a speed range. By including specific propulsion data of the ship, a requested power is obtained for the speed range. The maximum speed is finally interpolated using the maximum available shaft power. The simulations are carried out for three different ship types with different hull shapes and propulsive power. The results show a significant decrease of travelling time for 2007 compared to 2000. Further in 2007 the season in which transport via the NSR is profitable is clearly extended to the winter months. In a second work task the program is further developed with respect to the determination of fuel oil consumption and exhaust gas emission. Due to increased resistance during ice breaking, high thrust has to be provided at low speed leading to an off design condition for propulsion arrangements which are optimised for service speed in open water. It can be found that the resulting actual fuel consumption is closely related to the operation profile of the ship. High values for fuel consumption thereby occur at service speed in ice free water but also at very low speeds in very tough ice conditions. For moderate ice conditions the fuel consumption and related emissions can be lower especially if the ship is forced to slow steaming for safety reasons.
