Control device for internal combustion engine

Номер: US20120010801A1
Автор: Kaoru Ohtsuka, Kiyonori Takahashi, Naoto Kato, Shinichi Soejima
Принадлежит: Toyota Motor Corp

In a control device which uses a specific physical quantity as a control variable of an internal combustion engine, and controls the internal combustion engine by manipulation of one or a plurality of actuators, switching of setting of a manipulation variable based on a required value of a physical quantity and setting of the manipulation variables by direct instruction to individual actuators is performed without generating discontinuity in a realized value of the physical quantity. When a manipulation variable instruction value directly designating a manipulation variable of an actuator is present, the manipulation variable instruction value is converted into a value of a physical quantity which is realized in the internal combustion engine by the operation quantity instruction value. When a deviation between a physical quantity conversion value converted from the manipulation variable instruction value and the physical quantity required value is within a predetermined range, switch of information for use in setting of the manipulation variable of each of the actuators is permitted.

Engine combustion control at low loads via fuel reactivity stratification

Номер: US20120247421A1
Автор: Derek A. Splitter, Reed M. Hanson, Rolf Deneys Reitz, Sage L. Kokjohn
Принадлежит: Individual

A compression ignition (diesel) engine uses two or more fuel charges during a combustion cycle, with the fuel charges having two or more reactivities (e.g., different cetane numbers), in order to control the timing and duration of combustion. By appropriately choosing the reactivities of the charges, their relative amounts, and their timing, combustion can be tailored to achieve optimal power output (and thus fuel efficiency), at controlled temperatures (and thus controlled NOx), and with controlled equivalence ratios (and thus controlled soot). At low load and no load (idling) conditions, the aforementioned results are attained by restricting airflow to the combustion chamber during the intake stroke (as by throttling the incoming air at or prior to the combustion chamber's intake port) so that the cylinder air pressure is below ambient pressure at the start of the compression stroke.

Принадлежит: Toyota Motor Corp

Precise operation of an accelerator operating member ( 7 ) is more difficult to perform in a reversing operation of a vehicle ( 1 ) as compared with an advancing operation. Therefore, behavior of the vehicle ( 1 ) is not smooth and thus tends to be unnatural. In the reversing operation of the vehicle ( 1 ), driving force output from an internal combustion engine ( 2 ) is limited in accordance with vehicle acceleration (D). At this time, it is possible to regulate the driving force of the vehicle ( 1 ) in conformity to the actual operation of the accelerator operating member ( 7 ) by the driver. In addition, limitation of the driving force is not executed in the advancing operation of the vehicle ( 1 ). At this time, the vehicle ( 1 ) can be driven in a state in which the driving force is comparatively small. Therefore, it is possible to prevent the behavior of the vehicle ( 1 ) from being unnatural. Accordingly, limitation of the driving force output from the internal combustion engine ( 2 ) can be properly carried out in accordance with the moving direction of the vehicle ( 1 ).

An engine torque compensation method is based on a change in the concentration of ethanol for a Flexible Fuel Vehicle (FFV). In the method, a concentration of ethanol in fuel that is supplied to an engine is acquired. A driver-required torque based on an opening rate of a throttle valve depending on manipulation of an accelerator by a driver is calculated. A torque correction factor depending on the opening rate of the throttle valve and the concentration of the ethanol is calculated. A final driver-required torque is obtained by multiplying the torque correction factor by the driver-required torque.

An output signal line connects a connection point of the signal lines and an output terminal. A first comparator circuit outputs a signal “1” when a current flowing in the line between the power supply and the connection point is larger than a normal current flowing into the ground from the power supply in a normal state. A second comparator circuit outputs a signal “1” when a current flowing in the line between the connection point and the ground is larger than the normal current. When the signal “1” is output from the first comparator circuit or the second comparator circuit, a cutoff circuit turns off a switch disposed in the output signal line.

Synergistic induction and turbocharging includes the use of one or more throttles in close proximity to each cylinder intake valve to control air flow in each intake port delivering air to combustion cylinders in an internal combustion engine system. A turbocharger may also be affixed in close proximity to each cylinder exhaust valve to enable a synergistic combination of hyper-filling cylinders with combustion air and immediate harvesting of exhaust gas by adjacent turbochargers. In some implementations the turbochargers may be low-inertia turbochargers. The combination of individual throttles per intake port and a turbocharger in close proximity to each cylinder enables faster ramp-up of an engine in the early stages of acceleration. Various implementations thus provide improved fuel economy and improved engine performance in tandem, instead of one at the expense of the other. 1.

Synergistic induction and turbocharging in internal combustion engine systems

Номер: US20180058307A1
Автор: C. Thomas Sylke, James R. Clarke, Richard J. Fotsch
Принадлежит: Bright Acceleration Technologies LLC

Synergistic induction and turbocharging includes the use of one or more throttles in close proximity to each cylinder intake valve to control air flow in each intake port delivering air to combustion cylinders in an internal combustion engine system. A turbocharger may also be affixed in close proximity to each cylinder exhaust valve to enable a synergistic combination of hyper-filling cylinders with combustion air and immediate harvesting of exhaust gas by adjacent turbochargers. In some implementations the turbochargers may be low-inertia turbochargers. The combination of individual throttles per intake port and a turbocharger in close proximity to each cylinder enables faster ramp-up of an engine in the early stages of acceleration. Various implementations thus provide improved fuel economy and improved engine performance in tandem, instead of one at the expense of the other.

Synergistic Induction And Turbocharging In Internal Combustion Engine Systems

Номер: US20200072122A1
Автор: Clarke James R., Fotsch Richard J., Sylke C. Thomas
Принадлежит: Bright Acceleration Technologies LLC

Synergistic induction and turbocharging includes the use of one or more throttles in close proximity to each cylinder intake valve to control air flow in each intake port delivering air to combustion cylinders in an internal combustion engine system. A turbocharger may also be affixed in close proximity to each cylinder exhaust valve to enable a synergistic combination of hyper-filling cylinders with combustion air and immediate harvesting of exhaust gas by adjacent turbochargers. In some implementations the turbochargers may be low-inertia turbochargers. The combination of individual throttles per intake port and a turbocharger in close proximity to each cylinder enables faster ramp-up of an engine in the early stages of acceleration. Various implementations thus provide improved fuel economy and improved engine performance in tandem, instead of one at the expense of the other. 1.
