Appl. No.:

13/248652

Inventors:

Brad Alan Boyer - Canton MI, US
Matthew Aaron Younkins - San Jose CA, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

F02B 43/00

US Classification:

123298, 123305, 123638, 123527

Abstract:

An engine having cylinders capable of combusting gaseous fuel includes at least one spark plug per cylinder, a gaseous fuel injector extending into each cylinder and having at least one nozzle cluster containing a one or more nozzles positioned to direct gaseous fuel only toward a spark gap of an associated spark plug, and a control system operating each spark plug and each injector to deliver gaseous fuel directly to the cylinder and initiate combustion. A method for controlling an engine capable of operating with gaseous fuel includes injecting the gaseous fuel directly into each cylinder through a centrally located injector having a plurality of clusters of nozzles, each cluster associated with one of at least two spark plugs positioned closer to a cylinder wall than to the injector, each cluster directing the gaseous fuel toward an associated spark plug gap.

Abstract:

An engine system comprises an air cleaner, a combustion chamber coupled to an intake port, and an intake manifold. The intake manifold is configured to receive air from the air cleaner, and, under some conditions to receive exhaust from the combustion chamber. The engine system further comprises a multifunction, barrel-type throttle valve coupled to the intake port via an outlet, the throttle valve having a first inlet coupled to the intake manifold and a second inlet coupled to the air cleaner.

International Classification:

H02P 6/10

Abstract:

A method of controlling an electric motor includes receiving a duty cycle for the electric motor for delivering a target torque from the electric motor, generating a pulse train, and pulsing the electric motor with the generated pulse train. Generating the pulse train being at least partially based on the received duty cycle. The generated pulse train optimized to improve at least one of noise, vibration, or harshness of the electric motor when compared to a constant pulse frequency.

Abstract:

A skip fire engine controller and method of control is described wherein during transitions from a first firing density to a second firing density, a firing density and a pumping density are separately set so as to balance the conflicting demands of (a) torque control, (b) Noise, Vibration and Harshness (NVH), (c) air flow through the engine and (d) air-fuel ratio.

F02D 41/06
F01L 9/16

Abstract:

A system and method for controlling an internal combustion engine involving (1) cylinder trapping strategies where one of several pneumatic spring types are dynamically selected for cylinders based at least partially on a predicted number of upcoming skips for each of the cylinders respectively and/or (2) staggering various valvetrain dependent operational engine strategies as operating conditions permit as the internal combustion engine warms up following a cold start.

Abstract:

In various aspects, internal combustion engines, engine controllers and methods of controlling engines are described. The engine includes a camshaft and a two cylinder sets. Cylinders in the first are deactivatable and cylinders in the second set may be fired at high or low output levels. The air charge for each fired working cycle is set based on whether a high or low torque output is selected. In some implementations, the camshaft is axially shiftable between first and second positions. First cam lobes are configured to cause their associated cylinders to intake a large air charge during intake strokes that occur when the camshaft is in the first position. Second cam lobes for cylinders in the second set cause their associated cylinders to intake a smaller air charge when the camshaft is in the second position. Second cam lobes for cylinders in the first set deactivate their associated cylinders.

Abstract:

The present invention relates generally to techniques for improving fuel efficiency of a vehicle powered by an internal combustion engine capable of operating at various displacement levels.
