“…For more than 95% of time during the operation, the electronic injector shut-off valve is in the closed state and the size of the section of the valve clearances during wear is no more than 5% of its bore in the open state [1,9]. Fuel leaks in the closed valve position occur only through the clearance in the valve seat mating (Figure 1).…”

“…Almost all the modern diesel fuel equipment (FE) is provided with microprocessor controls and is characterized by high injection pressures (up to 220-250 MPa), due to high requirements for the level of energy, economic and primarily environmental indicators of internal combustion engines [1][2][3][4][5][6]. The most promising from fulfilling all the strict requirements for emission of harmful substances, noise level and fuel economy are accumulator fuel supply systems of the Common Rail (CR) type [7][8][9][10].…”

This paper presents a method for the vehicle speed estimation with a Fuzzy Logic based algorithm. The algorithm acquires the measurements of the yaw rate, steering angle, wheel velocities and exploits a set of five Fuzzy Logics dedicated to different driving conditions. The technique estimates the speed exploiting a weighted average of the contributions provided by the longitudinal acceleration and the credibility assigned by the Fuzzy Logics to the measurements of the wheels’ speed. The method is experimentally evaluated on an all-wheel drive electric racing vehicle and is valid for the front and rear wheel drive configurations. The experimental validation is performed by comparing the obtained estimation with the result of computing the speed as the average of the linear velocity of the four wheels. A comparison to the integral of the vehicle acceleration over time is reported.

In fuel economy, a rising level of interest in heavy duty diesel engines that industry has witnessed over the last few years continues to go up and this is not likely to change. Lowering the fuel consumption of all internal combustion engines remains a priority for years to come, driven by economic, legislative, and environmental reasons. According to statistics, the share of operating expenses to ensure transport operations in industrial production is 15-20%, wherein 16-30% of the total volume of transport operations concerns a car, tractor, and trailer. During transport operations, the engine load by the torque, in most cases, does not exceed 40-50%. The paper investigates the increase in fuel efficiency of cars and tractors by disconnecting some of the engine cylinders operated in low-load and idling modes. The research has led to the establishment of the theoretical dependencies between the effective power, engine efficiency, mass of the transported cargo, speed of the car (tractor) and the number of disconnected engine cylinders. Results of experiments suggest the interdependencies of the performance parameters of the car (tractor) when disconnecting some of the engine cylinders. It has also been established that the maximum reduction in the hourly fuel consumption occurs in the idling mode while it decreases along with an increase in the load.

The technology used for high-pressure fuel pumps running at fixed camshaft speeds does not provide running-in of friction pairs not only for the pump, but also for its fuel injection advance clutch. The purpose of the research is to develop a device that provides an equally variable angular velocity of the driven clutch half of the fuel injection advance clutch. The uneven speed of rotation of the driven half-coupling makes it possible to run the clutch in dynamic loading conditions by optimizing the stroke of the pushers, the radius of the rollers and the height of the programming washer, while ensuring optimal running-in modes with a combination of specified torsional vibrations in the range of amplitudes that overlap the operating angles of turn of the half-couplings. To achieve this goal, the work determined the range of sizes of the radii of the driven semi-shaft of the proposed device (6…12.5 mm) and its copying roller (5…9 mm), which provides an equally variable angular velocity of the driven half-coupling. For these values of the structural elements of the device, the height of the cam of the programming washer will be in the range of 2.99 ... 5.85 mm. In this range, it is possible to run commercially available fuel injection advance clutches in dynamic mode with an equally variable angular velocity, which improves the quality of running-in of the friction pairs of the pump and its clutch.
