This paper investigates the opportunity of using almond oil as a renewable and alternative fuel source. Different fuel blends containing 10, 30, and 50% almond biodiesel (B10, B30, and B50) with diesel fuel (B0) were prepared and the influence of these blends on emissions and some performance parameters under various load conditions were inspected using a diesel engine. Measured engine performa...

This paper presents the implementation of polynomial vector back propagation algorithm (PVBPA) for estimating the power, torque, specific fuel consumption and presence of carbon monoxide, hydrocarbons in the emission of a direct injection diesel engine. Experimental readings were obtained using the biodiesel prepared form the waste low quality cooking oil collected from the canteen of Sri Saira...

three types of vehicles, pride, peugeot 405 glx and paykan were tested from the point of view of exhaust emissions (co, hc, nox) and fuel consumption, on chassis dynamometer running european standard driving cycle with three kinds of fuels, mtbe free unleaded regular gasoline (urg) as base fuel and 10 and 15 volume percent mtbe –gasoline blends as comparable fuels. utilizing mtbe blended fuels ...

This study studies the relationship between tyre pressure and fuel consumption of vehicles using experimental methods and mathematical model to predict vehicle fuel consumption. The model obtained was F = 0.62722.5941p+3.3428p±0.018 where F is the fuel consumed and p is the tyre pressure of a vehicle, which can also be used to predict the amount of fuel consumed by other vehicles. The model was...

Previous research described the use of machine learning algorithms to predict aircraft fuel consumption. This technique, known as Virtual Sensors, models fuel consumption as a function of aircraft Flight Operations Quality Assurance (FOQA) data. FOQA data consist of a large number of measurements that are already recorded by many commercial airlines. The predictive model is used for anomaly det...

Falling oil revenues and rapid urbanization are putting a strain on the budgets of oil producing nations which often subsidize domestic fuel consumption. A direct way to decrease the impact of subsidies is to reduce fuel consumption by reducing congestion and car trips. While fuel consumption models have started to incorporate data sources from ubiquitous sensing devices, the opportunity is to ...

aIn the present study a 4-stroke 5hp diesel engine was tested with Diesel oil plus cottonseed oil blends. The blends in different proportions (10 to 50 percent by volume) were tested at constant speed of 1500 rpm. The said engine is operated at different loads and characteristics like Brake power, Brake thermal efficiency, specific fuel consumption etc. Engine performance for blends resulted in...

This paper builds a model for estimating the fuel consumption of a taxiing aircraft using flight data recorder information from operational aircraft. The taxi fuel burn is modeled as a linear function of several potential explanatory variables including the taxi time, number of stops, number of turns and number of acceleration events, and the coefficients are estimated using least-squares regre...

abstract soil compaction is a main factor that reduces the cane yield in sugarcane fields, in southwest of iran, especially in ratoon cropping system. therefore, sub-soiling practices could alleviate adverse effects of compaction and increased yield. in according to this aim, a study was to evaluate the effect of  ratooning practice systems consisting of control (no subsoiler), two and four sha...
