Abstract: Methods and systems are provided for a cooling system. In one example, a cooling system comprises a device for regulating a coolant flow, where the device is in force-fit connection to a plurality of crankshafts, each crankshaft corresponding to a single cylinder of a plurality of cylinders. The cooling system further comprises a plurality of injectors for injecting coolant onto outer surfaces of the plurality of injectors.

Abstract: An autonomous or semi-autonomous vehicle and maneuvering method for a vehicle for overcoming an obstacle may include detecting the obstacle in front of and/or behind the motor vehicle by a detection device, moving the motor away from the obstacle to come to a standstill at a defined distance x, wherein the running direction of a wheel is facing towards the obstacle. The method may also include accelerating the motor vehicle toward the obstacle within a power-limiting range of a drive unit of the vehicle. The power-limiting range may be a power-limiting range of an electric motor powering the vehicle.

Abstract: A turbocharged internal combustion engine is provided with at least a partially variable valve train on an intake side wherein the intake valves are controlled to optimize the actuation of a second inlet valve in relation to a first inlet valve for different load conditions.

Abstract: Systems and methods are provided for operation of fuel injectors within an applied-ignition, direct-injection internal combustion engine. In one example, a needle of a fuel injector is moved from a retracted position to an extended position relative to a plurality of injection holes of a nozzle of the fuel injector, with at least one injection hole being separated from a fuel supply system earlier than each other injection hole. In a partially retracted position, fuel flow along a first side of the needle is decreased relative to fuel flow along a second side of the needle.

Abstract: Methods are provided for an engine including modifying fuel injection timing based on engine operating conditions. A delay time period calculation may be based on a comparison of a first engine load with a second engine load. Further, a modified injection start time, based on a delay time period, may include injecting fuel during the compression cycle of an engine.

Abstract: A folding bicycle has a main-frame with a bottom bracket, crank, pedals, and a seat post. A front is attached to the main-frame by a front hinge having an axis parallel to the crank axis, and has a mono-fork suspension. The front frame rotates about the front hinge to a folded position wherein the mono-fork is behind the front hinge axis. A rear swingarm suspension has a rear sprocket and is attached to the main-frame by a rear hinge that preferably is coincident with the crank axis. The swingarm is of a single-stay configuration and is rotatable about the rear hinge to a folded position wherein the rear sprocket is forward of the crank axis. The main-frame may consist of left and right sidewalls spaced apart from one another, and the mono-fork lies at least partially between the sidewalls when the front frame is in the folded position.
