    Abstract: An active fuel pressure pulsation cancellation technique includes receiving, at a controller of an engine having a camshaft-driven fuel pump, an unfiltered fuel pressure signal indicative of a measured pressure of fuel in a fuel rail. The technique includes detecting, at the controller, fuel pressure pulsations in the fuel rail based on the unfiltered fuel pressure signal. The technique includes generating, at the controller, a cancellation signal based on an opposite polarity of the fuel pressure pulsations. The technique also includes controlling, by the controller, an actuator associated with the fuel rail using the cancellation signal to cause the actuator to generate liquid-borne cancellation pulsations that cancel the fuel pressure pulsations in the fuel rail.

    Abstract: In a diesel engine, displacement of an amount of fuel injection Δf is calculated on the basis of a reference amount of heat production Qb and an actual amount of. heat production Qr, and an amount of fuel injection from an injector is corrected on the basis of the displacement of an amount of fuel injection Δf. Displacement of a heat production rate gradient AS is calculated by subtracting an actual heat production rate gradient Sr from a reference heat production rate gradient Sb, displacement of an amount of intake air ΔΑ on the basis of the displacement of heat production rate gradient AS and the displacement of the amount of fuel injection Δf, and the amount of intake air is corrected by adjusting a supercharging pressure of a turbocharger on the basis of the displacement of the amount of intake air ΔΑ. Accordingly, it is possible to adjust the amount of fuel injection and the amount of intake air.

    Abstract: A dual-mode fuel injector has an internal part containing a variable volume chamber space which fills with fuel at common rail pressure and a plunger which is operable to force fuel out of the variable volume chamber space and to be injected out of the nozzle through the injection orifices at amplified pressure greater than common rail pressure. The plunger and the internal part have respective surfaces which come into mutual abutment during filling of the variable volume chamber space with fuel at common rail pressure and which, when in mutual abutment, create a seal which seals fuel in the variable volume chamber space against escape from the variable volume chamber space past the seal.

    Abstract: Apparatus for converting an in-line six cylinder engine into a engine having three operational modes including providing (1) a new camshaft which cause the pistons of the inner, outer and intermediate pairs of cylinders which move together to have in phase piston cycles, (2) a new gasket which provides a passage between the inner cylinders and a new computer module which causes the engine with the new camshaft and gasket to selectively operate in the three modes. The method of conversion includes replacing the new apparatus components with existing components of the engine. Also discussed is an inverted V engine having two banks of cylinders converging from separate crankshafts with their combustion chamber closely spaced with passages therebetween.
