INTERNAL COMBUSTION ENGINE, IN PARTICULAR AS DRIVE ENGINE FOR A VEHICLE
An internal combustion engine, as a drive engine for a vehicle, including an engine braking device having a throttle element which is associated with an exhaust gas section, for damming an exhaust gas which is emitted by a combustion device, and including a measuring device by means of which the exhaust gas pressure can be measured at a defined measuring region of the exhaust gas section upstream of the throttle element as seen in the exhaust gas flow direction. According to the disclosure, it is provided that at least one further measuring device is provided, by means of which the exhaust gas pressure can be measured at the defined measuring region, for realizing a redundant exhaust gas pressure measurement, and the measurement signals which are determined by means of the measuring devices can be transmitted to a controller for controlling the throttle element.
Inter-connect circuit device for vehicle fuel delivery system
An inter-connect circuit (ICC) device for a fuel delivery system of a vehicle is disposed between an engine control unit (ECU) and a fuel control device. The ECU transmits a drive pulse to the fuel control device by way of a drive pulse line passing through the ICC device. The ICC device includes a housing and a sense circuit. The housing has a first side that is connectable to the ECU and a second side different from the first side that is connectable to the fuel control device. The sense circuit is disposed within the housing. The sense circuit is electrically coupled to the drive pulse line by way of a sense circuit line and is communicably coupled to the ECU by way of a data communication line.
OUTBOARD MOTOR AND MARINE VESSEL
In an outboard motor, one of an engine control unit and a power supply control unit is mounted on a first side surface of an engine, and the other of the engine control unit and the power supply control unit is mounted on an upper surface of the engine.
Flow rate measuring device
The present disclosure provides a flow rate measuring device including a flow rate detecting body, a humidity detecting body, and a base. The flow rate detecting body protrudes inside of an intake passage. The humidity detecting body protrudes inside of the intake passage at a position away from the flow rate detecting body. The base is connected to the flow rate detecting body and the humidity detecting body. The humidity detecting body holds a sensor chip that includes a humidity detecting element sensitive to the humidity of the intake air. A length, along a flow direction of the intake air, of an exposed portion of the humidity detecting body is defined as a referential length. The humidity detecting element exists within a range from an upstream end of the exposed portion of the humidity detecting body to a position of half the referential length.
Method and apparatus for modifying an automobile engine control unit
A secondary controller for controlling the performance of an automobile is described. The secondary controller can be configured to temporarily reprogram one or more vehicle controllers, such as the engine control unit, after the automobile has been powered on. The secondary controller can substitute command sets with different command sets by rewriting the corresponding portion of RAM. The secondary controller can receive vehicle information from the engine control unit to determine the particular type of vehicle to locate the particular command in RAM in order to rewrite the command set. In one embodiment, the secondary controller communicates with the vehicle controller via the vehicle's diagnostic port, such as an OBD-II port. In another embodiment, the secondary controller can be configured to control a variable displacement engine in a vehicle to command the vehicle to operate using all available cylinders.
Temperature management for throttle loss recovery systems
Systems and methods are provided for managing temperatures associated with a throttle loss recovery system. One exemplary system includes a flow control assembly for recovering energy from a fluid bypassing a flow control valve based on an orientation of the flow control valve, a conduit providing fluid communication with the flow control assembly for the portion of the fluid flow bypassing the flow control valve, and an electronics assembly including an electronics module coupled to the flow control assembly. At least a portion of the electronics assembly is in fluid communication with the portion of the fluid flow bypassing the flow control valve, thereby allowing for heat transfer between the electronics assembly and the fluid bypassing the flow control valve.
Electronic device
The present disclosure provides an electronic device including a casing, a terminal, a substrate, an electric connector, and a conductive adhesive. The terminal is fixed to the casing. The substrate is attached to the casing at a position where at least a portion of the substrate faces the terminal. The electric connector is fixed to a circuit wiring formed in the substrate at a position where the substrate faces the terminal. The electric connector protrudes toward the terminal from the circuit wiring. The conductive adhesive electrically and mechanically connects the terminal to the electric connector.
Fuel injection valve with cylinder internal pressure sensor
Within a resin mold portion of a fuel injection valve, an amplifying member having a substrate is provided. An engagement hole that penetrates in an axial direction is formed in another end part of the amplifying member, and an engagement pin, which is formed on a bobbin of a housing, is inserted through the engagement hole. A second connector of a second signal transmitting member, which constitutes part of a signal transmitting unit, is inserted from below into a connecting hole formed in the substrate. In addition, when the resin mold portion is molded, the amplifying member is retained in a state with the engagement pin and the second connector being inserted, respectively, into the engagement hole and the connecting hole.
Motor vehicle internal combustion engine control apparatus
The purpose of the present invention is to provide a motor vehicle internal combustion engine control apparatus which is constructed as a waterproof structure capable of having a long life while minimizing an increase in surface area of a case and a cover, thereby enabling miniaturization, decrease in cost, and increase in reliability to be satisfied. The motor vehicle internal combustion engine control apparatus is equipped with a substrate, a connector, and a case and cover which enclose the substrate, a waterproofing adhesive being disposed at a junction part between the cover and the case. Recessed portions are disposed at the junction part between the case and the cover. The sidewalls of one of the recessed portions are inserted into the other of the recessed portions to form a gap which is folded a plurality of times between the case and the cover and extends between the inside and the outside of the case and cover, said gap being formed so that the size of the gap on the outer side is formed to be larger than the size of the gap on the inner side. The gap is configured to be fluid-tight by the waterproofing adhesive filled in the gap.
