This study aims to determine the influence of distance traveled of used oil on fuel consumption rate and its maximum combustion temperature. In terms of consumption rate, used oil combustion tends to be slow because it must reach a certain point in order to burn. The maximum combustion temperature of used oil is comparable to other ordinary fuels, and it is suitable for use in metal casting. The study concluded that the longer the distance traveled, the faster the fuel consumption rate required. Used oil of 2200 km distance traveled is the fastest to burn, 0.8 liters in 745 seconds. The slowest to burn is the one with a distance traveled of 1800 km, which burns in 1031 seconds. The farther the distance traveled yields in a lower combustion temperature reached. At a distance traveled of 1800 km, the maximum temperature is 963.3 °C, while at 2200 km, the maximum temperature is 797.5 °C.Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh jenis oli bekas terhadap waktu konsumsi bahan bakar dan suhu maksimal pada pembakaran oli bekas. Ditinjau dari segi kecepatan konsumsi bahan bakar, pembakaran oli bekas konsumsinya cenderung lambat karena oli bekas harus mencapai titik tertentu agar dapat terbakar. Ditinjau dari suhu maksimal yang dihasilkan mampu bersaing dengan kompor – kompor dengan bahan lainya dan juga untuk ukuran kompor pengecoran logam sudah memadahi. Pada penelitian tersebut, dapat disimpulkan bahwa semakin jauh jarak tempuh maka semakin cepat/ rendah waktu konsumsi bahan bakar yang diperlukan. Jarak 2200 km merupakan waktu tercepat untuk menghabiskan 0,8 liter oli bekas dengan waktu 745 detik. Sementara waktu terlama yaitu 1031 detik pada jarak 1800 km. semakin jauh jarak tempuh maka suhu maksimal yang dihasilkan semakin rendah. Pada jarak 1800 km menghasilkan suhu maksimal mencapai 963,3 OC, sementara jarak 2200 km hanya mampu menhasilkan suhu maksimal sebesar 797,5  OC.

Taking a plateau high-pressure common-rail diesel engine as the research model, a model was established and simulated by AVL FIRE according to the structural parameters of a diesel engine. The combustion and emission characteristics of D, B20, and B50 diesel engines were simulated in the plateau atmospheric environment at 0 m, 1000 m, and 2000 m. The calculation results show that as the altitude increased, the peak in-cylinder pressure and the cumulative heat release of diesel decreased with different blending ratios. When the altitude increased by 1000 m, the cumulative heat release was reduced by about 5%. Furthermore, the emission trend of NO, soot, and CO was to first increase and then decrease. As the altitude increased, the mass fraction of NO emission decreased. As the altitude increased, the mass fractions of soot and CO increased. Additionally, when the altitude was 0 m and 1000 m, the maximum temperature, the mass fraction of OH, and the fuel–air ratio of B20 were higher and more uniform. When the altitude was 2000 m, the maximum temperature, the mass fraction of OH, and the fuel–air ratio of B50 were higher and more uniform. Lastly, as the altitude increased, the maximum combustion temperature of D and B20 decreased, and combustion became more uneven. As the altitude increased, the maximum combustion temperature of B50 increased, and the combustion became more uniform. As the altitude increased, the fuel–air ratio and the mass fractions of OH and NO decreased. When the altitude increased, the soot concentration increased, and the distribution area was larger.

In order to study a new clean and efficient combustion mode, which can relieve the pressure of traditional energy and ensure low emissions, in this study, a diesel/natural gas dual fuel engine is designed by non-dominant sorting genetic algorithm (NSGA-?), and its thermodynamic characteristics are studied. The WP10.290 Diesel engine is modified into a diesel/natural gas dual fuel engine. The emissions of harmful substances and thermal efficiency of the modified engine under different working conditions are compared. The combustion chamber structure and adaptability between combustion chamber and injection parameters are optimized by using NSGA-II algorithm and CFD software. The results show that the emission of NOx and CH4 and the fuel consumption rate can be reduced simultaneously by using the composite combustion model compared with the original engine. When the CH4 emission is close to zero, the fuel consumption rate decreases obviously, and NOx slightly increases. When the angle between the injection holes is 141.57? the amount of NOx in the cylinder is large. When the injection advance angle is 21.91?CA, the pressure in the cylinder is the highest, the CH4 production is the lowest, the NOx production is higher, and the oxygen content in the combustion mixture is less. The NOx production is the lowest. diesel/natural gas dual fuel engine can ensure efficient combustion while reducing emissions. In this study, the performance of the dual fuel engine at various speeds can be further studied, which can provide theoretical support for the design of diesel/natural gas dual fuel engine.

A biomass combustor based dryer was evaluated with different biomass for drying of ginger. Biomass combustor based dryer consists of fuel hopper, combustion chamber, heat exchanger, grate for proper combustion of the combustible gas, chimney, ambient air inlet, hot air outlet and drying chamber. The system was evaluated at five fuel consumption rate (1 to 5 kg.h–1) and five air flow rate (100, 150, 200, 300 and 400 m3.h–1) using maize cobs, sized wood and saw dust briquettes for ginger drying. The experimental performances show that the hot air temperature inside the dryer vary between 36 to 81ºC for maize cobs, 53 to 85ºC for sized wood and 49 to 87ºC for biomass briquettes at tested air flow rate and fuel consumption rate in the system. The maximum efficiency of the system was found at the fuel consumption rate of 1 kg.h–1 and 400 m3.h–1 air flow rate using maize cobs, sized wood and saw dust briquettes as fuel respectively. The cost of operation of ginger drying at 1 kg.h–1 fuel consumption rate and 400 m3/h air flow rate was Rs. 32.76, 34.26, 34.76 and 55 per hour using maize cobs, sized wood, saw dust briquettes and mechanical drying system, respectively. Hence, the drying of ginger in biomass combustor based dryer using maize cobs at 1 kg.h–1 fuel consumption rate and 400 m3/h air flow rate resulted in better performance.

China has set stringent fuel consumption rate (FCR) targets to address the serious environmental and energy security problems caused by vehicles. Estimating the technological progress and tradeoffs between FCR and vehicle attributes is important for assessing the viability of meeting future targets. In this paper, we explored the relationship between vehicle FCR and other attributes using a regression model with data from 2009–2016. We also quantified the difference in the tradeoff between local and joint venture brands. The result showed that from 2009 to 2016, if power and curb mass were held constant, 2.3% and 2.9% annual technological progress should have been achieved for local and joint venture brands, respectively. The effectiveness of fuel-efficient technologies for joint venture brands is generally better than that of local brands. Impacts of other attributes on FCR were also assessed. The joint venture brands made more technological progress with FCR improvement than that of local brands. Even if 100% of technological progress (assume the technological progress in the future were the same as that of 2009–2016) investment were used to improve actual FCR after 2016, it would be difficult to meet 2020 target. Accelerating the adoption of fuel-efficient technologies, and controlling weight and performance, are both needed to achieve the 2020 and 2025 targets.

Theoretical investigation with reasoning of petrol fuel combustion in the ambient and ozone medium was made. Methods of carrying out the experiment using the engine loading method due to application of power of mechanical losses of deactivated cylinders were worked out. Experimental studies envisage determination of influence of ozone additive into fuel air mix on the basic effective ICE performance, for this purpose cyclic fuel consumption parameter was used. After the analysis of ICE performance methods and control techniques, its condition was evaluated, for this purpose a compressor meter was used with preliminary pressurization of cylinders. During the experiment in order to load the engine its third and fourth cylinders were switched off. The results showed that the utmost fuel efficiency is found at crankshaft rotation values of 1450 and 3350 min-1, when cyclic fuel consumption rate has values of 1,35 and 1,27 mg/cycle respectively, which makes 7,4 and 7,0 % from identical indicators without ozonation of air mass at the same rotations. In general, the effect of fuel air mix ozonation makes it possible to develop target petrol-operated engine rotations at smaller fuel consumption rate, this way increasing its energy efficiency.
