“…As illustrated in Figure 1, a typical single-piston high-pressure fuel pump is constructed with control valve assembly, pumping chamber, outlet check valve, pressure relief valve and plunger. 8 The pump pressurizes and transports fuel through the reciprocating motion of plunger driven by a roller tappet, which changes the pumping chamber volume. Figure 1(a) shows the pumping state, during which the armature rod is pushed to the right by a spring with the electromagnetic coil in power-off state.…”

“…6,7 A typical GDi system includes high-pressure fuel pump, fuel line, fuel rail and injector. 8 The low-to-high pressure transmission is the key process for GDi system. As execution apparatus of this process, the high-pressure fuel pump plays an important role and always generates significant noise, which is induced mainly by pressure fluctuation, jet impinging, high aped flow, and operations of control valve or driven mechanism.…”

With the wide application of gasoline direct injection system, its noise problem is becoming increasingly prominent under serious competitive environment. As the primary noise source of the engine in idle condition, the significant noise generated by the low-to-high pressure transmission part of high-pressure fuel pump becomes more and more serious. This paper focuses on the driving component of high-pressure fuel pump, the roller tappet, and experimentally studies effect factors of impact noise induced by it at engine idle. Both the impact occurrence time and position are analyzed from the combined vibration acceleration and crankshaft/camshaft rotation angle signals in the time domain according to the structure and kinematic mechanism of the roller tappet. The influences of the axial clearance between roller and tappet shell, the engine rotation speed and the lubrication conditions are investigated by experiments. The experimental results show that the lubrication is the primary factor for the roller tappet induced impact noise reduction. A significant improvement about 83% can be achieved under pressure lubrication.

“…As aresult, GDI (gasoline direct injection)engines have emerged as serious contenders, having significant advantages in fuel economy,output power and environmental impact,however, GDI engines generate increased noise due to components such as high-pressure fuel pumps, fuel injectors and fuel rails that are integral to the engine itself. Such noise has increasingly become an issue [1],therefore it is important to identify the noise sources and relative contributions for the refinement of the GDI engine.…”

In this paper,the sound intensity and airborne source quantification methods were used to estimate the airborne noise radiating from ag asoline direction injection engine and the relative contributions of each of the engine's components to such airborne noise. In order to estimate noise contribution using airborne source quantification, the sound volume velocity for the source should be estimated. In previous methods, the sound volume velocity wasestimated using the inverse method, whereas in this paper,the sound volume velocity is estimated directly. Forthis work, the sources of noise radiating from thegasoline direction injection engine were first identified by measuring the sound intensity of the noise sources while the engine wasrunning idle. The sound volume velocities of these sources were estimated from the product of the area of that noise source and the directly measured particle velocity.Inorder to validate this method, twospeakers with different frequencies were installed in an anechoic chamber and the contribution of each source wase stimated. Finally,t his proposed method wasa pplied to the identification and contribution of noise sources in agasoline direction injection engine.
