31-86 PROIECTAREA ȘI TESTAREA SOLUȚIEI DE CUPLARE LA CÂRLIG A UNEI REMORCI LA UN AUTOVEHICUL UTILITAR TOT TEREN DE TIP CF MOTO 500-2A

Designing and testing the coupling solution of a trailer at the hook of utility all terrain vehicle CF MOTO 500-2A

 

All-Terrain Vehicles are today quite popular and often known both as entertaining systems as well as utility equipment. The scientific paper shows a small contribution to the design and implementation of a practical solution for coupling the trailer to the ATV tow. There was used a dynamometric sensor in order to measure the inertial forces during braking process in various conditions of driving the ATV CF MOTO 500-2A, considering all the time accelerating and decelerating manoeuvres in the case of trailer towing, when a traction mass is placed on the vehicle’s hook, due to the attached trailer. The importance of studying the kinematic and dynamic aspects of ATV’s driving process resides in significance that the trailer inertia force has on the road train during some driving manoeuvres of cornering, decelerating and accelerating.

Contributions to the experimental research of ELECTRONIC DIESEL CONTROL (EDC) MODULe operation in relation with supply of the n47 engine from BMW 320d (e90) automobile

 

The present scientific paper analyzes through latest technologies in the field the operation parameters obtained in practical measurements. There are few detailed studies related to the problem of the electronic diesel control operating parameters of the N47 engine in the model E90, also known as BMW 320d on the available international data bases. There are many such vehicles on the roads in EU, and USA. The electronic diesel control module has a significant influence on the eco-performances (fuel efficiency and carbon-foot-print). Testing the electronic control systems on BMW diesel engines offers solutions and important ideas for optimizing their environmental pollution and fuel savings, while the operation will not be influenced. This paper is developed by testing the electronic diesel control system in order to gain an insight in its operation. The actual values are captured, close analyzed and interpreted.

The experimental work presented in this paper shows some of the achievements during practical testing of the suspension system and wheel train in order to gain information on their influence upon adherence or road contact stability. The experimental tests were conducted in order to point out the influence of suspension springs, tires and dampers on the adherence and road contact between tires and sustaining surface. There were examined the weight axle and suspension efficiency on each wheel of the vehicle during vibration of the testing plates. In the experimental work are also specified the main vehicle components and the suspension test-bed infrastructure in order to gain further more quality and definition of the practical procedure. The opportunity and main significance of testing the suspension quality at different vibration frequencies and for each wheel of the two vehicle’s axles in order to point out adherence level is based on the capacity of test-bed and on the importance of vibration influences in vehicle’s over-all performance.

contributions to the EXPERIMENTAL RESEARCH OF INJECTION FUEL SUPPLY SYSTEM FROM 3.0i ENGINE OF BMW X 5 ROAD VEHICLES

 

This scientific article shows the results of multiple experimental tests and researches made on the basis of fuel injection process during different operating regimes. Measured parameters are in this case engine speed, fuel consumption, injection timing and engine temperature.

The main objective of these tests is to determine how fuel consumption is influenced by engine speed and engine coolant temperature if the vehicle is operating in neutral gear that means the engine has no load on the crankshaft. In this case the engine speed will be correlated with the accelerating pedal position. The road vehicle on which the tests will be conducted is BMW X5 3.0i model years 2002. There aren’t any detailed studies made on this model. It is a well-known that a considerable number of such vehicles are registered in our country. Besides this body type, BMW Factory equipped other vehicles with this engine.

The experimental tests offer engineers a better understanding of injection process and fuel economy in the case of conventional fuel supply systems. The experimental data are summarized and accurately analyzed and represented.
