A heat recovery apparatus having a circuit that during operation circulates a working medium. The circuit may include an evaporator to evaporate the working medium, an expander arranged downstream of the evaporator to expand the working medium, and a condenser arranged downstream of the expander configured to condense the working medium. The expander may include a shaft to draw a torque at the expander. An injector pump may drive the working medium. The injector pump may include a driving fluid inlet, a suction inlet, and an injector outlet. The driving fluid inlet may be fluidically connected to the circuit between the evaporator and the expander. The suction inlet may be fluidically connected to the circuit between the condenser and the evaporator. The injector outlet may be fluidically connected to the circuit between the suction inlet and the evaporator.

The present invention relates to the field of energy recovery from hot exhaust gases, a type of system that is widely used in industrial generator assemblies to produce steam used in industrial processes or cold to cool perishables or to cool environments. The system according to the present invention applies to the recovery of energy from exhaust gases in small generator assemblies, smaller than 10 MW, and comprises a turbo (1) connected to the exhaust gas outlet (2) in a small power plant generator assembly (3) and in which said turbo (1) is connected to a hydraulic pump (4), which generates pressure and transmits this pressure to a hydraulic pressure accumulator (5) which, in turn, sends hydraulic fluid under pressure for a hydraulic motor (6) of constant speed, which moves a pulley (7), and said pulley (7), in turn, moves another pulley (8), installed directly on the alternator shaft (9) of the generator assembly (3). In addition to pulleys (7,8), the movement can be done through a gear/clutch system or through a torque converter.

In some embodiments of the present disclosure, an electric motor is used to generate correction torques to counteract unwanted torque pulses generated by an internal combustion engine during a cylinder deactivation mode. In some embodiments, the electric motor may be mounted to an accessory drive such as a power take-off mechanism or a front end accessory drive (FEAD). In some embodiments, the correction torques may be determined using an engine model. The correction torques help to reduce or eliminate noise, vibration, and/or harshness (NVH) during the cylinder deactivation mode.

In some embodiments of the present disclosure, an electric motor is used to generate correction torques to counteract unwanted torque pulses generated by an internal combustion engine during startup and/or shutdown. In some embodiments, the electric motor may be mounted to an accessory drive such as a power take-off mechanism or a front end accessory drive (FEAD). In some embodiments, the correction torques may be used to enforce an engine speed target profile for startup or shutdown, and may be determined using a feedback control loop based on the engine speed. The correction torques help to reduce or eliminate noise, vibration, and/or harshness (NVH) during startup and/or shutdown.

A hybrid oil pump for a vehicle with an engine. The hybrid oil pump includes an oil pump unit with a pump shaft, a mechanical drive to drive the oil pump unit in a mechanical driving mode, an electrical drive to drive the oil pump unit in an electrical driving mode, a switchable clutch arranged between the motor shaft and the pump shaft, and a freewheel clutch to automatically couple the mechanical drive with the pump shaft when a rotational speed of the mechanical drive is higher than a rotational speed of the electric motor. The oil pump unit pumps pressurized oil to a vehicle component. The mechanical drive is mechanically connected to and driven by the engine. The electrical drive includes an electric motor and a motor shaft. The switchable clutch mechanically disengages the electrical drive from the oil pump unit in the mechanical driving mode.
