Publication number: 20140041633Abstract: A dual fuel compression ignition engine operates by injecting gaseous fuel and liquid diesel fuel from a common fuel injector directly into each engine cylinder. The gaseous fuel is ignited by compression igniting a small pilot injection quantity of the liquid diesel fuel. Evaporated natural gas from a cryogenic tank and/or a fuel conditioning module is dosed into an intake manifold of the engine with an electronically controlled supply valve. The electronically controlled supply valve may open to supply evaporated gas to the intake manifold contingent upon combustion conditions in the engine cylinder demonstrating a low risk of methane slip, and the dosing quantities are limited to reduce risk of ignition of an air/gas mixture in the intake manifold.Type: ApplicationFiled: August 8, 2012Publication date: February 13, 2014Applicant: CATERPILLAR INC.Inventors: Hoisan Kim, Mark F.

Publication number: 20140041637Abstract: The method for controlling the operation of an internal combustion engine comprises at least two operating modes. In a first operating mode, the intake valve is closed at a first predetermined crank angle, in accordance with the Miller cycle, before the piston reaches bottom dead center during the intake stroke for reducing pressure in the cylinder, and fuel is injected using first fuel injection means optimized for large amounts of fuel. In a second operating mode the intake valve is closed at a second predetermined crank angle, in accordance with conventional intake valve closing timing, after or slightly before the piston has passed bottom dead center, and fuel is injected using second fuel injection means optimized for small amounts of fuel. The invention also concerns an internal combustion engine.Type: ApplicationFiled: October 12, 2011Publication date: February 13, 2014Inventors: Mikael Troberg, Luca Zuanigh, Anton Wintersteller, Christer Hattar, Gino Rizzetto, Diego Delneri
