Use of pressurized fuels in an internal combustion engine

Номер: US20120085314A1
Автор: James M. Cleeves
Принадлежит: Pinnacle Engines Inc

An amount of inlet air can be delivered to a combustion volume of an internal combustion engine via an air inlet port, and delivery of an amount of a fuel from a compressed fuel reservoir to the combustion volume can be controlled via a pressurized fuel inlet port positioned to the deliver the amount of the fuel directly into the combustion volume separately from the air inlet port. The amount of the fuel can be controlled relative to the amount of the inlet air to create an air-fuel mixture within the combustion volume having a target air/fuel ratio. In other aspects, a vehicle chassis can be designed to incorporate a compressed fuel reservoir as a structural part of the chassis. Methods, system, and articles of manufacture relating to these features are described.

A predictive alignment process for aligning coupled rotating shafts extending from a pair of adjacently located rotating machines. The process includes a step of monitoring the rotating machines to obtain physical characteristics that change during operation and could cause variance in alignment between a non-operating state and an operating state. The process would monitor changes in alignment and correlate the changes in physical characteristics and the operational alignment. The process can monitor and record environmental conditions proximate the rotating machinery and correlate the operational alignment and the environmental changes to provide predictive alignment directions used to guide an alignment engineer to align coupled shafts where the alignment is optimized when in operation.

Disclosed is an energy retriever system and methods for absorbing energy and using that energy elsewhere or converting it to other useful forms of energy or work. The energy retriever system consists of a series of components interconnected by a plurality of conduits containing a fluid. Working as a self-contained thermodynamic system, the energy retriever system allows the fluid to circulate through all of these elements. Heat added to the energy capture subsystem heats the fluid. The fluid becomes more pressurized and moves into the expansion cycle subsystem. The energy extraction subsystem transforms the thermal energy of the fluid into work, kinetic energy or thermal energy. The reservoir subsystem compresses the fluid and reintroduces it into the energy capture subsystem. One-way valves are used throughout the system to keep the flow of the fluid in one direction and separate sections of the system that contain different pressures.

A method and a system for starting an internal combustion engine (ICE) having a crankshaft and an electric turning machine (ETM) operatively connected to the crankshaft are disclosed. An absolute angular position of the crankshaft related to a top dead center position of a piston in a combustion chamber of the ICE is determined. Electric power is delivered to the ETM at a first level to rotate the crankshaft. Electric power is then delivered to the ETM at a second level greater than the first level when the piston reaches a predetermined position before the TDC position. Fuel is injected in the combustion chamber after the piston has passed beyond the TDC position. The fuel is then ignited. In an implementation, the ICE is started in less than 110 degrees of rotation of the crankshaft.

When start control is initiated, the start control device operates in a first operating mode in which an upper limit value of an engine speed is limited to a first upper limit value (NErev 1 ) that is lower than an upper limit value (NErev 0 ) in a non-start control. When an elapsed period of time after a throttle opening has exceeded a predetermined opening in the first operating mode reaches a predetermined standby time, the start control device operates in a second operating mode in which the upper limit value of the engine speed is limited to a second upper limit value (NErev 2 ) that is lower than the first upper limit value. The start control device transitions to an ordinary mode to thereby terminate the start control when a period of time of the second operating mode reaches a predetermined control period of time or a forced cancellation condition holds.
