fuel feeding - Opis:
- This paper describes the way of modernization of the direct operation fuel feeding system of diesel engine. Effective, ecological and economical characteristics of a modern diesel engine are greatly de-termined by parameters of using fuel-feeding system. Thus, in modern conditions, fuel-feeding systems have to fulfil specified requirements, which are mainly connected with fuel supply process intensification, possibility of adaptable regulation of fuel injection lead angle, cycle fuel delivering and injection characteristic at full range of engine operation regimes. At present time accumulator fuel feeding systems Common Rail type, fulfil these requirements best of all. However, despite its advantages, those kinds of systems have number of disadvantages. The main ones are high price and structural complexity of the system elements. Because of this Common Rail does not have wide using in the diesel engines with number of cylinders less than three. Although that type of diesels exactly is universal mechanical energy, source and can be used in many types of machinery, including ones with strict ecological norms. However, up to now these engines are equipped with the direct operation fuel feeding system that despite its high reliability and low price is worse than accumulator systems in the injection pressure level and possibilities of fuel feeding process control. Thus, main objective of a modernization of the direct operation fuel feeding system is topical. Speed forcing of high-pressure fuel pump was used. Maximal injection pressure is successfully increased 1.42 times. It provides intensification of fuel injection process. Implementation of the electronic control allows counting this method of fuel feeding system modernization promising for small diesel engines.
