Being Quiet is the Best Way to Be Heard: Minimizing Fuel System Noise

Drivers expect a lot out of their vehicles, and one of these expectations is what you hear – or rather what you don’t hear – while in the driver’s seat. To give vehicle owners the best driving experience possible, Stanadyne has set out to build the quietest high-pressure GDI pumps on the market. With the rise of gasoline direct injection (GDI) in the past decade, automotive fuel systems are operating at higher pressures than ever before – and with higher pressure comes the risk of more noticeable noise from the fuel system.

IMPORTANCE OF NOISE
 There are several factors that contribute to audible noise from the engine. However, noise is subjective. Some drivers prefer the roar of a performance engine while others favor the silence of a luxury sedan. In either case, unwanted sounds from the engine interfere with those expectations. That’s why we are constantly working to make sure noise from the fuel system is the last thing a driver hears from the engine.

ACOUSTICAL ANALYSIS
 The noise that a driver hears is a composite of all the different sources of sound that the vehicle makes. Complicating matters, noises that engine components make can emanate through the engine and vehicle structures to radiate in unexpected ways. At Stanadyne, we understand how important these interactions are, so we optimize the noise signature of all our GDI pumps on-engine in a unique sound isolation chamber. Our engineers use the data from this ultra-advanced facility at our Connecticut headquarters, along with powerful hydraulic and acoustic analysis tools, to optimize our pumps to produce the best possible overall noise signature on the actual engine on which it will run. It’s the only way to get the job done right.

QUIETTECH™
 With help from state-of-the-art facilities, our patented QuietTech™ technology, and customer feedback, we are constantly refining our strategies to reduce hydraulic and mechanical noise. Our latest QuietTech™ components maximize the efficiency of the pump to minimize the volume of fuel flow, reduce the velocity and mass of moving parts, incorporate hybrid materials and material coatings and seal surface finishing techniques. These efforts result in GDI pumps that run as quietly as possible in each engine application.

We are pushing the boundaries of what’s possible in noise reduction through QuietTech™ and advanced analysis techniques. As engine technology continues to progress, demanding better fuel efficiency and lower emissions, new challenges in pump design will emerge. We keep GDI technology moving forward by building solutions that exceed expectations for our customers. These efforts go toward our commitment to fueling innovation.
