An electric car draws lots of power that needs to be on board the moving vehicle. An adaptive power supply can combine a variety of sources of electrical energywhich may include an internal combustion engineand use those different sources to efficiently produce the electrical power required. An adaptive power supply provides optimal performance by sensing changing conditions, often hundreds of times per second, and then adapting itself to those conditions in order to optimize efficiency at each particular instant during a car's operation. Those conditions may include changes in user inputs, machine operating conditions, and machine operating parameters. Having multiple sources of electrical power allows effective control of more independent power parameters, enabling greater freedom to adapt to optimize efficiency. That gives adaptive power supplies that are cheaper, smaller, lighter, more powerful, and more efficient than conventional designs.

A reciprocating piston engine is disclosed having a first inner magnetic field unit comprising a first inner magnetic field unit arranged on a first crank arm of a crankshaft including a magnetizable material, and a stationary first outer magnetic field unit. The first inner magnetic field unit and the first outer magnetic field unit together form a first electromechanical converter. The first crank arm has a first securing surface on a face which points radially outwards with respect to a crankshaft axis and which is opposite a first connecting rod bearing. A first counterweight is fixed to the first securing surface in a formfitting manner in the radial direction, said first counterweight including a non-magnetizable material. The first magnetic field unit is arranged on a counterweight face pointing radially outwards with respect to the crankshaft axis.

An intake cam is positioned between first and second shaft supports that support an intake camshaft. An exhaust cam is positioned between third and fourth shaft supports that support an exhaust camshaft. An ignition plug unit extends between the intake camshaft and the exhaust camshaft and inward of the intake cam and the exhaust cam with a cylinder axis defining a reference position. A cylinder head includes a joint plane that is joined to a cylinder body. In a case where a virtual plane is defined by the joint plane and is perpendicular or substantially perpendicular to the cylinder axis, a distance between a portion, closest to the virtual plane, of the intake camshaft and the virtual plane is less than a distance between a portion, farthest from the virtual plane, of the intake port and the virtual plane.

The present disclosure relates to a pipeline for supplying a gas to an internal combustion engine, with a pipeline cross section forming a passage for the gas and a gas mass measuring device for measuring a gas mass flow. The pipeline is characterized in particular in that it comprises a mixing element made from a wire structure upstream from the gas mass measuring device and in that the mixing element serves for the thorough mixing of the gas in order to homogenize an inhomogeneous flow profile which is present upstream from the mixing element.

A vehicle includes an electric motor and an engine selectively coupled to the electric motor. The vehicle has an electric motor controller configured to, in response to (i) an absence of receiving a motor command signal within a predetermined time, (ii) a battery voltage being below a first threshold and (iii) a motor speed exceeding a second threshold, restrict operation of the electric motor to a limited operating mode and control the electric motor to generate a charging torque for a battery.

A vehicle driving device includes an engine, an electric pump, an electric heater, a starter motor, and a control system. The control system calculates a first actual viscosity of an engine oil based on a load torque of an electric pump. The control system causes an electric heater to operate by supplying a first energy to the electric heater and calculates a second actual viscosity of the engine oil based on the load torque of the electric pump. The control system calculates, based on the second actual viscosity of the engine oil and a target viscosity of the engine oil, a second energy that is to be supplied to the electric heater. The control system causes the electric heater to operate by supplying the second energy to the electric heater and then drives a starter motor so as to cause an output shaft to perform starting rotation.

A control method for a hybrid work machine including an internal combustion engine which includes an exhaust gas treatment device, a generator motor which is connected to an output shaft of the internal combustion engine, and an electrical storage device which stores electric power generated by the generator motor or supplies electric power to the generator motor, the control method for the hybrid work machine includes: determining whether the hybrid work machine is in a regeneration state in which a regeneration is performed by the exhaust gas treatment device; setting a threshold value for starting a generation of power by the generator motor to a minimum generation torque as a lower limit value when it is determined that the exhaust gas treatment device performs a regeneration; and controlling the generator motor based on the set threshold value.

An apparatus for controlling a startup of an engine includes an engine, an engine controller configured to check whether the startup of the engine is prepared to generate information on whether the startup is prepared when an ignition is turned on, a hybrid controller configured to check whether communication with the engine controller is normal and to generate information on whether the hybrid controller is normal, the hybrid controller causing a vehicle to be driven only in an EV mode or generating a start control signal for the startup of the engine, according to whether the EV mode is engaged when a start signal is input from a driver, and a starter driver configured to start the engine in response to the start control signal.

A gasifier energy production device including: a gasifier device including a fuel inlet, an air inlet, and a fuel gas outlet; a heat engine including an air inlet, a fuel gas inlet, and an exhaust gases outlet; a battery; an electrical current generator, the heat engine is coupled to at least the electrical current generator and the electrical generator is coupled to the battery; and a controller such that all fuel gas produced by the gasifier device once the gasifier device produces sufficient gas to make the heat engine operate and until the heat engine has stopped is injected into the engine such that energy required at an output from the energy production device is independent of the production of fuel gas.

A motor-assisted non-uniform displacement engine control system includes a non-uniform displacement engine comprising a plurality of cylinders, the cylinders comprising at least two kinds of cylinders having different displacements, a motor connected to a driving shaft of the engine, an energy storage device for supplying electrical energy to the motor, and a motor control unit for controlling the motor, wherein the motor control unit controls the motor to compensate for a difference in torque due to different displacements of the cylinders such that a sum of engine torque and motor torque during an explosion stroke of each cylinder is uniform.
