With 110-d incubation experiment in laboratory, the responses of microbial quantity, soil enzymatic activity, and bacterial community structure to different amounts of diesel fuel amendments were studied to reveal whether certain biological and biochemical characteristics could serve as reliable indicators of petroleum hydrocarbon contamination in meadow-brown soil, and use these indicators to ...

In CI engines, the evaporation rate of fuel on various hot surfaces, including the combustion chamber, has a significant effect on deposit formation and accumulation, the exhaust emissions of PM and NOx, and their efficiency. Therefore, the evaporation of liquid fuel droplets impinging on hot surfaces has become an important subject of interest to engine designers, manufacturers, and researcher...

An experimental investigation has been carried out for the first law analysis of a DI (direct-ignition) diesel engine running on straight soybean oil (SVO) preheated at 50, 75, 100C with different loads at varying speeds of 1750, 2000, 2250 rpm. The results show that preheated straight soybean oil may be a practical replacement of the conventional diesel fuel with a small power and efficiency d...

The use of plant-based systems to remediate contaminated soils has become an area of intense scientific study in recent years and it is apparent that plants which grow well in contaminated soils need to be identified and screened for use in phytoremediation technologies. This study investigated the effect of diesel fuel on germination of selected plant species. Germination response varied great...

Using low price heavy fuel oil (HFO) in high-speed diesel engines is a practical way to reduce running costs. However, most high-speed diesel engines’ fuel systems and combustion systems cannot adapt to HFO. This causes the problem of deterioration of combustion performance. In order to solve this problem, the authors have modified the fuel injection system and combustion system of a high-speed...

Background: This study aims to measure the output torque and analyze the exhaust elements of a small diesel engine that use the diesel fuel mixed with waste cooking oil to validate the driving and environmental characteristics of this fuel. Methods: The fuel used was diesel fuel mixed with 15% of waste cooking oil, a small quantity of additives and was produced with no complicated refining proc...

in this study, the mf285 tractor engine vibrations resulting from the use of different combinations of biodiesel, bioethanol and diesel as fuel were studied. engine vibrations in three directions and three engine speeds: 1000, 1600 rpm 2000 and ten fuel level was measured. to investigate the influence of measured parameters on engine vibration of factorial design in a randomized complete block ...

The paper discusses the influence of two fatty acid methyl esters (bioesters) derived from soybean oil (SME) and from rapeseed oil (RME) on the lubricity of the petroleum diesel fuels: Ekodiesel (S:26 mg/kg, HFRR: 555 m) and Citydiesel (S: 8 mg/kg, HFRR: 617 m). High-frequency reciprocating rig (HFRR) equipment was used to examine diesel fuels, neat bioesters and blends containing from 0,1 % up...

China’s fuel quality standards and fuel supply management have long been an impediment to improved air quality by hindering the progress of vehicle emission control. This paper summarizes the status of China’s fuel quality standards, fuel supply and vehicle emission standards focusing on the major problems of fuel quality management. The mechanism that China uses to establish its fuel quality s...

Diesel engines are widely used to power trucks, buses, passenger cars, locomotives, and ships. These engines power the heavy equipment that plants and harvests crops, tills soil, clears and reshapes land for roads and buildings, and hauls ores from mines to processing centers. Diesel engines generate electricity as portable power sources, peaking units, and emergency backups when line power is ...
