The Influence of Fuel Pump Pressure Variations on the Performance of 2-Stroke Gasoline Direct Injection Engines

The direction of technological development in 2-stroke gasoline direct injection engines is to improve engine performance and reduce exhaust gas pollution, where the solution to achieve this is to use a high-pressure electric fuel pump that produces stable fuel pressure and is practical in its application. This research aims to determine the influence of variations in fuel pressure on the performance, especially torque and power, of a 2-stroke gasoline direct injection engine. Tests were carried out on a 110 cc 2-stroke gasoline direct injection motorcycle engine using Research Octane Number (RON) 90 fuel at varying fuel pressures of 7.5 Bar, 8 Bar, and 8.5 Bar on a chassis dynamometer to obtain engine performance data in the form of torque and power.

The Effect of Fuel Pump Pressure and Number of Injector Holes on 150cc Matic Motorcycle Performance

This study aims to evaluate the effects of increasing fuel pump pressure and varying the number of holes in the injector on engine performance. The fuel system in the engine has evolved from carburettor to injection system to improve the efficiency of fuel usage. In this study, the fuel pump pressure was increased to three levels, namely 2.5 bar, 3 bar, and 3.5 bar. In addition, variations in the number of holes in the injector were also tested using 3-hole, 6-hole, and 8-hole injectors. Engine performance was evaluated based on the power and torque produced. The research method used is experimental with power and torque measurements as engine performance data. The results showed that increasing fuel pump pressure and varying the number of holes in the injector had a significant effect on engine performance. Increasing the fuel pump pressure to 3.5 bar results in an increase in engine power and torque. The best power test results were obtained at a fuel pump pressure of 3 bar with a combination of 6-hole injectors, producing a maximum power of 11.63 HP at 6000 rpm engine speed. While the best torque test results were obtained at a fuel pump pressure of 3.5 bar with a combination of 3-hole injectors, producing a maximum torque of 43.10 Nm at 3000 rpm. The variation in the number of holes in the injector shows that the use of injectors with more holes tends to increase engine power and torque.

Performance analysis of a hybrid pulse detonation engine using liquid hydrogen as fuel

Aimed at enhancing the comprehensive performance of the air turbo rocket engine (ATR), two schemes of hybrid pulse detonation engine (PDE) configurations based on the ATR were proposed. The engines are fueled by liquid hydrogen, and the oxidant is the incoming air or self-carried liquid oxygen. The ideal thermodynamic cycle processes of the engines were analyzed, and the relevant mathematical models were established. The fuel pump pressure ratio of the ATREX and the oxidant-fuel ratio of the ATR-GG are respectively used as iterative variables. The performances of the two engine schemes at the design point were obtained and compared with that of the traditional ATR. The results show that, under ideal conditions, the specific thrust and specific impulse of the hybrid PDE based on the ATREX are about 20% higher than those of the traditional ATREX. Moreover, the mass of the oxidant required by the hybrid PDE based on the ATR-GG is about 49.5% lower than that of the traditional ATR-GG, while the specific thrust and specific impulse are not reduced as compared with those of the traditional ATR-GG.

Diesel Engine Fuel Pump Pressure, Time Setting and Calibration

Abstract: For a diesel engine, fuel pressure time setting and calibration are very important parameters, which influence and increase the engine efficiency, performance, emissions, and combustion. Other injection parameters affecting engine performance are rate of injection, injection pattern, number of injections etc. A single cylinder research engine was used to experimentally determine the effects of fuel injection strategies and injection timings on engine combustion, performance and emission characteristics. The experiments were conducted at constant speed (2500 rpm) with two FIPs (500 and 1000 bars respectively) and different start of injection (SOI) timings. Cylinder pressure and rate of heat release (ROHR) were found to be higher for lower FIPs however advanced injection timings gave higher ROHR in early combustion stages. Brake thermal efficiency (BTE) increased with increased injection pressures while exhaust gas temperature and brake mean effective pressure (BMEP) increased up to 500 bars. These parameters reduced slightly with increase in fuel pressure time pump. Diesel engine combustion quality is based on the formation of fuel-air mixture. Enormous efforts have made to reduce the harmful diesel engine emissions. High engine noise, Particulate matter (PM) and NOx production are the results of improper combustion process and considered as the major constraints. The performance and emission characteristics of diesel engines depend on many parameters. Precise control over the fuel injection process is one of the most important factors and plays a very important role in combustion to increase the engine performance with minimal exhaust emission. The injection system must satisfy high pressure capability, injection pressure control, flexible timing control, and injection rate control. The purpose of this study is to find the performance and exhaust emission of diesel engines by implementing the combination of various high injection pressures and variable injection timings. Present paper is concentrated towords optimization of the best combination of high pressure injection with suitable injection timing in a diesel engine fueled with pure diesel, to reduce the emission and fuel consumption with increased engine power. Keywords: Diesel Engine fuel pump pressure, time,setting and calibration.

추력 30톤급 액체로켓엔진의 에너지 밸런스 해석

An energy balance analysis is conducted for a 30 t thrust level liquid rocket engine. The relations between thrust and combustion pressure, between thrust and propellant flow rate, and between combustion pressure and fuel pump pressure rise are compared against those indicated by a published database of the existing rocket engines. A combustion pressure higher than the old design value is obtained, implying that the present design is high-performance oriented. The thrust to propellant flow rate ratio is the same as that of the existing engines, indicating that the specific impulse performance is at the usual level. The fuel pump pressure rise is found to be slightly high when the combustion pressure is considered, and it is attributed to the pressure budget of the present ground test engine not being optimized.

Development of High Pressure Fuel Pump for DI Engine

Direct injection (DI) is becoming increasingly popular among gasoline automotive engines, due to its benefits for fuel consumption and engine output. A key component of a DI system is the fuel pump, which must deliver fuel at much higher pressures than a conventional spark ignition (SI) engine. For a DI fuel pump, maximum fuel flow rate, maximum operation speed, electrical power consumptions and noise are conflicting requirements. This paper describes the development of a compact single-cylinder DI fuel pump which achieves increased fuel flow rates while consuming decreased electrical power and generating less noise, compared to conventional DI fuel pumps currently in the market. This is achieved by the introduction of a new concept for the flow rate control valve, so called normally close valve. The construction of this valve allows it to have smallest air gap between magnetic surfaces at valve open position, which makes it possible to generate high magnetic force with less electrical energy. Moreover, the magnetic force is used for handling hydraulic force, which makes it possible to handle higher flow rate. In addition, the flow rate control valve moves passively by the hydraulic forces, such that the impact noise at valve opening is reduced significantly.

Leak Fault Detection of Liquid Rocket Engine Based on Strong Tracking Filter

The propellant leak is one of the most common and especially dangerous faults in liquid rocket engine (LRE). By analyzing the performance of the engine, we know that the leak of hydraulic lines can be expressed as the variation of the e uid resistance coefe cients. If leaks occur in the hydraulic line, the corresponding e uid resistance coefe cients will be changed. An approach is presented to detect and diagnose the leak of hydraulic line based on a strong tracking e lter. The method uses a strong tracking e lter to estimate the e uid resistance coefe cients and to compare the estimated e uid resistance coefe cients with their normal values. Then the modie ed bias method is used to detect the leak fault. We simulate the leaks occurring in the main system or in the subsidiary system of LRE. The results show that the approach is feasible.
