Patent number: 9441569Abstract: Systems and methods are provided for an engine. The system comprises a direct injection engine having a cylinder in which a piston is slidingly supported to form in combination with a cylinder head a combustion chamber; a fuel injector for the cylinder having a catalytic coated tip portion that projects into the combustion chamber; and an electronic controller to control the operation of the engine and operates the engine in a heating mode of operation if heating of the fuel injector tip is requested. Various methods for heating the fuel injector tip are proposed including operating the engine on a reduced number of cylinders and varying one or both of fuel injection timing and quantity of fuel injected and the ignition timing in order to increase the temperature of combustion.Type: GrantFiled: May 13, 2013Date of Patent: September 13, 2016Assignee: Ford Global Technologies, LLCInventors: David Skipp, Graham Hoare, Oliver Berkemeier, Nicholas Dashwood Crisp

Patent number: 7240751Abstract: A hybrid electric vehicle powertrain has an engine and a motor at the torque input side of a power transmission. The motor has a single stator and dual rotors. A selectively engageable rotor clutch connects the rotors together for torque delivery during a driving mode. During a key start and a rolling start of the engine, the rotor clutches are selectively engaged and released.Type: GrantFiled: May 9, 2005Date of Patent: July 10, 2007Assignee: Ford Global Technologies, LLCInventors: Graham Hoare, Walt Ortmann
