Latest Patents

One of Johnson's latest patents is for a stoichiometric high-temperature direct-injection compression-ignition engine. This innovative engine features a thermal barrier coated combustion chamber and an injection port that injects fuel satisfying a stoichiometric condition with respect to the intake air. Additionally, it includes a mechanical exhaust regenerator that transfers energy from exhaust gas to intake compression stages. The design incorporates an exhaust sensor that inputs to a feedback control system to deliver quantified fuel. A variable valve actuation (VVA) system controls valve positions, while an exhaust gas temperature sensor manages exhaust feedback by closing the exhaust valve early according to the VVA. The engine also utilizes an exhaust-gas-recirculation (EGR) system, heat exchanger, and flow path connecting an air intake, load command input, and a computer that operates the EGR based on exhaust temperature signals and changes in VVA timing.
