摘要： Provided herein is a control system for a vehicle. The control system includes an engine including cylinders, each of the cylinders including a fuel injector associated therewith, a vehicle exhaust system coupled in fluid communication with the engine for receiving exhaust gas therefrom, a sensor coupled to the vehicle exhaust system to detect an air-to-fuel ratio of the exhaust gas, and an engine electronic control unit (ECU) communicatively coupled to the sensor and the fuel injector of each cylinder, the ECU including memory and a processor. The ECU is configured to store a sequence of operating states of the cylinders, determine, based on the stored sequence of operating states, expected air-to-fuel ratio (ATFR) value data, receive, from the sensor, actual air-to-fuel ratio (ATFR) value data, determine a difference between the expected and actual ATFR value data, and control operation of the fuel injector based on the determined difference.

摘要： An internal combustion engine includes first and second power cylinders and an expander cylinder, and is configured to operate in an expander mode and a bypass mode by selectively fluidly coupling exhaust flow from the first and second power cylinders to the expander cylinder. Operation includes commanding a transition from the bypass mode to the expander mode, including retarding openings of intake valves of the first and second power cylinders to a LIVC position. Exhaust valves of the power cylinders are controlled to effect fluid flow to the expander cylinder, and opening of an outlet valve of the expander cylinder is controlled to a maximum advanced state. The openings of the intake valves of the first and second power cylinders are controlled to desired positions associated with engine operation in the expander mode.

摘要： A system including a combustion engine is disclosed. The combustion engine includes a first cylinder orientated along a first axis. The combustion engine also includes a first piston, fitted within the first cylinder, to move in reciprocating motion by alternately moving in a first linear direction along the first axis responsive to a first power stroke or a second linear direction along the first axis responsive to a second power stroke. The combustion engine includes a tensile band affixed to a first end and a second end of the first piston. The first piston is to exert a first tensile force on the tensile band in the first linear direction in response to the first power stroke. The first piston is to exert a second tensile force on the tensile band in the second linear direction in response to the second power stroke.

摘要： An illustrative example method of controlling an engine of a vehicle, includes determining a target pressure curve for a cylinder of the engine for a first combustion cycle, determining a heat release model for the cylinder for the first combustion cycle, determining a mass flow of fuel from the heat release model to achieve the target pressure curve during the first combustion cycle, and automatically controlling opening of an injector of the cylinder of the engine during the first combustion cycle to provide the determined mass flow of fuel to the cylinder. The method includes determining a real pressure curve during the first combustion cycle and automatically adjusting at least one of the heat release model or the mass flow for a second, subsequent combustion cycle based on a difference between the target pressure curve and the real pressure curve.
