Long Term Performance of a Sunflower Oil/Diesel Fuel Blend

The article addresses the long term effects of a 50% sunflower oil blend in diesels using the then current engine designs. A study regarding such is reviewed here. The fuel properties, it's characteristics, the apparatus, the procedure and fuel filter problem are given, injection nozzle carbon buildup and it's effects, carbon buildup in the intake port, the lubricating oil analysis, oil consumption and blowby, the condition of pistons, liners, rings and bearings, the turbocharger and fuel injection pump condition comprise this writing

The conception of modular monitor of car exploitation parameters

Current tendencies in electronics and informatics development going towards Internet of Things (IoT), Big Data or Data Cloud technologies create new possibilities in acquiring and utilizing data. The article presents the concept of modular monitoring of vehicles operating parameters. Presented device registers data from the OBD system and a set of independent, configurable sensor modules. Data from the OBD system is acquired via protocol. CAN Bus with a DLC connector. The signal from sensor modules is transferred via a Bluetooth wireless network. The registered data can be storage on board as CD card memory or alternatively on a typical user interface such as laptop, tablet, cell phone etc. The communication with the user interface is realised with USB. Moving vehicles modular monitoring system presented in the article can be used to attain a fuller representation of the vehicles state in relation to its environment. The base assumption of the device is maximal flexibility in term of sensors versality as well as possibilities of assembly on board. In connection with the concept, a prototype of the device was made and tested with an inertial measurement unit (IMU) module and a pressure sensor. Appliances modules are based on Cortex M4 and M0 processing units. A users interface in LabVIEW and examples of registered signals are showed at the end of the article

Short-Term Performance of Diesel Oil and Sunflower Oil Mixtures in Diesel Engines

Two studies are addressed in this article regarding the effects of sunflower oil and methyl ester when used in diesel engines. The first took place in the Department of Agricultural Engineering at the North Dakota State University. The second took place at the Allis-Chalmers Engine Division in Harvey, Illinois. Areas covered in this paper are: fuel properties and characteristics, performance tests on engines in Fargo, N.D., performance tests on engine at Harvey, Illinois. Thermal efficiency, volumetric energy, fuel flow, flow resistance, density and viscosity of test fuels, compression ratios, refinement percentages, the smoke number and exhaust temperature are topics which appear in these studies and paragraphs
