Valve Cleaner for GDI Engines Receives Patent

Feb. 19, 2020

CRC Industries Inc. has received a U.S. patent for its GDI IVD Intake Valve & Turbo Cleaner aerosol Article.

The patent number is US Patent No. 10,267,227.

The company says its patented technology includes systems for the reduction or elimination of intake valve deposits in gasoline direct injection (GDI) engines and related methods, including the delivery device, conduit, and actuator.

CRC GDI IVD Intake Valve & Turbo Cleaner cleans GDI intake valves when applied through the engine's air intake or throttle body and delivered directly to the back of the valves. As vehicle manufacturers began shifting to GDI technology, CRC says it was at the forefront in addressing the unique performance issues caused by carbon deposit buildup on GDI intake valves, such as hard starts, rough idle, poor acceleration, reduced fuel economy, excess emissions, and power loss.

The company says that prior to the invention of CRC GDI IVD Intake Valve & Turbo Cleaner, cleaning GDI intake valves was a costly, labor-intensive process, requiring engine disassembly to remove the valves for manual cleaning or walnut-shell blasting. With the new CRC GDI valve cleaner, the service can be performed up to 75% faster than previous methods and without engine teardown, freeing up valuable bay time for shops and saving hundreds of dollars for consumers.

“The number of vehicles with GDI engines in the U.S. is expected to exceed 80 million by 2021. Our proprietary technology provides a better service alternative to maintain GDI engines for both repair shops and vehicle owners, while also making the job manageable for the skilled DIYer,” says Adam Selisker, global VP of research and development for CRC Industries.
