Gumout Performance Additives would like to thank you for the great interaction you had with us in our last Q&A session. Hopefully, we were able to provide valuable insights into our products and educate on fuel additives in general.
In this next session, the focus will be on gasoline direct injection (GDI) technology and some of the performance issues that arise from these systems. While this fuel delivery system can add power and increased fuel economy over many of the port injected systems, some of the key components are now either subjected to extreme environments or they are now isolated from where the fuel is introduced to the combustion area of the engine.
For example, direct injectors are located in the combustion chamber, not located in the intake port. The extreme heat and pressure found in the combustion chamber cooks carbon deposits onto the tip of the direct injector causing fuel spray pattern problems. In addition, now that the valves are no longer being sprayed with detergents (either in the fuel itself or in higher doses from fuel additives) by the port fuel injector they begin to accumulate carbon build up through recirculated exhaust via the EGR/PCV valves.
However, there are solutions to these problems. Some take a bit more DIY expertise than others, or require use of more potent additives, but we’d like to open the topic up for discussion and share with you what we know.
Beginning today, the thread will be open for question submissions until 10 p.m. ET on Sunday June 14th, at which time we will send them back to our full team of scientists, engineers and brand representatives to provide answers to as many of the questions as we can within a few weeks.
We are extremely excited to provide you with this service, but do have a few requests:
1. Please use this forum ONLY to submit questions. If you have previously posted questions on other areas of the site we will do our best to find them and provide answers, but your best bet is to repost the question in this thread.
2. Please understand that there will be some questions that we will not be able to answer. Some of our formulation information is proprietary, such as how much of a certain additive we put in our products, and can only provide feedback on our areas of expertise.
3. Please understand that we will not speculate on the products of our competitors, but we may be able provide you with ways to determine what they may have in their formulations. Not all fuel additives are created equal, so question claims and benefits and demand more information on what is in the product, what tests were used to determine efficacy and what were those results.
We look forward to your questions and thank you for your involvement!
