In a vehicle control device for stopping an internal combustion engine when a vehicle is traveling at a predetermined speed or higher and a stop condition of the internal combustion engine is satisfied, fuel is injected to the engine even when the stop condition is satisfied, when an EGR rate of the internal combustion engine is equal to or higher than a set value. Alternatively, when the EGR rate is equal to or higher than the set value, an EGR valve attached to an EGR pipe of the engine is controlled in a valve closing direction when the stop condition is satisfied. Alternatively, when the EGR rate is equal to or higher than the set value, clutch engagement is maintained for a clutch control device that disconnects torque transmission between an output shaft of the internal combustion engine and a vehicle drive shaft, even when the stop condition is satisfied.

A device comprises: an injector for injecting fuel into an engine combustion chamber, a switch formed by an injector housing and an injector nozzle needle and which changes its switching state depending on a closed or open state of the injector, an input line for supplying energy to an actuating element which adjusts the nozzle needle in its two states, an output line for conducting energy away from the actuating element, and an evaluation unit for detecting the switching state of the switch, wherein a first switch contact of the switch is connected to an electrical input line of the injector, a second switch contact of the switch is connected to ground, and the evaluation unit is configured to carry out a signal measurement on the input line and/or an output line to conclude a switch state.

Various embodiments may adjust fuel injections to account for phase differences of the piston stroke and the valve strokes of a reciprocating-piston engine. For example: measuring dynamic pressure oscillations assigned of the air in the intake tract or the gas in the outlet tract; determining a crankshaft phase angle signal; determining the phase positions of selected signal frequencies of the oscillations in relation to the signal; determining lines of equal phase positions based on the phase positions of the selected frequencies; determining a common intersection point of the lines by projection into a common plane spanned by inlet valve stroke phase difference and outlet valve stroke phase difference and signal-frequency-dependent phase shifting; determining the inlet and outlet phase difference from the common intersection point; determining the piston stroke phase difference from the phase shift; and adjusting an amount of a fuel injection based on the determined differences.

A conductive ball stud fastener arrangement for providing energy to a removable electrified component having an electrified element when the component is attached to an electrified substrate is disclosed. The ball stud fastener includes an insulating body, an electrified conductor having a conductive tip that is continuous with a conductive, centrally formed conductive stem, and a conductive attachment portion for attachment to the electrified substrate. The electrified component includes grommets having conductive elements. The ball stud fasteners are easily removed from and attached to the grommets. The conductive elements of the grommets are part of a circuit to which the electrified element of the electrified component is attached. According to one embodiment, the conductive ball stud fastener arrangement and its associated circuit includes a photoelectric sensor that opens and closes the circuit. In another embodiment, the ball studs themselves act as switches to open and close the circuit.

A remaining fuel amount warning device for a vehicle, the remaining fuel amount warning device giving a warning that an amount of fuel remaining in a fuel tank is smaller than a predetermined value on the basis of output of a fuel gauge measuring the remaining fuel amount, includes combustion state changing device for changing the combustion state of an engine. When the remaining fuel amount becomes smaller than the predetermined value, the remaining fuel amount warning device performs remaining amount warning control that produces vibration different than during normal operation by changing the combustion state of the engine by the combustion state changing device. A starter switch for starting the engine is made to serve also as a warning acknowledging button for stopping the remaining amount warning control for a predetermined time on the basis of an operation by an occupant.

Disclosed is a controller for a turbocharged engine. The engine includes a supercharger configured to supercharge intake air using an exhaust gas from the engine, and including movable flaps arranged so that a boost pressure generated in an intake passage is adjustable. If a rotational speed of a turbine and compressor that constitute the supercharger has reached a first threshold lower than an endurance limit, an amount of fuel injected to the engine is reduced to a predetermined amount. If the rotational speed has reached a second threshold lower than the first threshold, the amount of fuel injected is reduced in accordance with an excess of the rotational speed over the second threshold.

A system according to the principles of the present disclosure includes an engine stall module and an actuator control module. The engine stall module identifies a potential engine stall based on a speed of an engine and a rate of change in the engine speed. The actuator control module selectively adjusts an actuator of a powertrain system to prevent the engine from stalling when a potential engine stall is identified.

A starting control device for an engine includes an ECU configured to: i) execute an autonomous starting control in which the ECU injects fuel into the cylinder from a fuel injection valve after a crank shaft rotates reversely before the crank shaft stops its rotation and then ignites an air-fuel mixture using an ignition plug to start the engine without using a starter motor; ii) determine whether a pressure in the cylinder increasing due to the reverse rotation is equal to or greater than a predetermined pressure at a time point of firing of the air-fuel mixture by the ignition; and iii) prohibit starting of the engine under the autonomous starting control when the ECU determines that the pressure in the cylinder is not equal to or greater than the predetermined pressure.

A control apparatus for an internal combustion engine according to the invention is applied to an internal combustion engine in which EGR gas and condensed water generated by an EGR cooler are supplied into a cylinder. The control apparatus calculates an equivalence ratio of the internal combustion engine, and controls an EGR valve and a condensed water supply valve such that, when the equivalence ratio is high, a supply rate of the condensed water increases and a supply rate of the EGR gas decreases relative to when the equivalence ratio is low.

Methods and systems for supplying starting a diesel engine that does not include glow plugs are described. In one example, a flow through a cylinder is limited during engine cranking to heat charge in a cylinder. In another example, a compressor is activated and air supplied to engine cylinders is heated via the engine and the compressor and recirculated to improve engine starting.
