Latest Patents

Rackmil holds a patent for a "System and method for controlling an engine." This innovative system includes an engine with multiple cylinders and an exhaust manifold. A fuel delivery device and an igniter are strategically placed in the exhaust manifold. The fuel delivery device injects fuel into the exhaust manifold, while the system also features an exhaust aftertreatment setup in fluid communication with the exhaust manifold. A controller communicates with the multiple cylinders, the fuel delivery device, and the igniter. This controller is designed to deactivate at least one cylinder to provide air to the exhaust manifold. It controls the fuel delivery device to inject fuel into the exhaust manifold, creating a mixture of fuel and air from the deactivated cylinder. The igniter is then controlled to ignite this mixture, generating combustion products within the exhaust manifold to heat the exhaust aftertreatment setup. This innovative approach enhances engine performance and efficiency.
