Abstract:
An engine assembly includes: a two-stroke internal combustion engine; a turbocharger operatively connected to the engine, the turbocharger having a compressor and an exhaust turbine; an intake pipe fluidly connected to the engine and to the compressor of the turbocharger; an exhaust tuned pipe fluidly connected to the engine and to the exhaust turbine of the turbocharger; a temperature sensor configured to generate a signal representative of a temperature of exhaust gas flowing within the exhaust tuned pipe; and a controller. The controller is configured to: determine a boost target pressure of the turbocharger based in part on the signal generated by the temperature sensor; and control the turbocharger to provide the boost target pressure to the engine. Methods for controlling an engine are also provided.
Abstract:
A drive aggregate for motor vehicles has an internal combustion engine (12) and a gearbox (18) which acts on the driving wheels of the motor vehicle. A gearbox input shaft (20) can be coupled to an output shaft (14) of the internal combustion engine. An electric machine (32) which can be coupled to the gearbox (18) by an intermediate gearbox (34) acts as a starter motor for starting the internal combustion engine (12) and as a generator for supplying the motor vehicle on-board network. In addition, the electric machine should ensure the synchronisation of the gearbox during gear shifts, together with at least one electronically controlled clutch and a flywheel mass (24). For the generator to always supply sufficient electric power, from idle running up to the nominal speed of rotation of the internal combustion engine, its speed of rotation is regulated depending on the engine speed of rotation by changing the transmission ratio of the intermediate gearbox.
Abstract:
A method and device to optimize the cumulative beneficial effect of harvesting all available forms of lost energy, including energy that is lost while a vehicle is in motion (e.g., kinetic, inertia, friction, thermodynamic, and aerodynamic losses). The cumulative energy that is recovered is converted to electrical energy which powers the on-board electrolyzer to produce more hydrogen and oxygen while the system is in operation and stationary. Stationary, passive means of energy, solar, wind, hydro, etc. will also be available to power the electrolyzer. The system also contemplates utilizing passive means of energy to power a non-mobile system which incorporates an internal or external combustion engine in place of a fuel cell.
Abstract:
A vehicle for driving drive wheels by integrating an engine output and a Rankine-cycle device output, wherein an accelerator pedal and a throttle valve are electrically connected via a DBW control device, and, when an accelerator opening ( theta ap) is increased as instructed by a driver, a throttle opening ( theta th) is increased in proportion to an accelerator opening ( theta ap) plus a correction amount ( DELTA theta th) to compensate for an insufficient reaction in output from the Rankine-cycle device due to its delay in output response. When an accelerator opening ( theta ap) is decreased as instructed by a driver, a throttle opening ( theta th) is decreased in proportion an accelerator opening ( theta ap) minus a correction amount ( DELTA theta th) to compensate for a surplus reaction in output from the Rankine-cycle device due to its delay in output response.
Abstract:
An energy conversion system system includes a powertrain (21, 1, 6, 7, 8, 11) capable to transfer mechanical power to (MP2) other devices (24, 10). An electromechanical system (20, 2, 3) is coupled to said powertrain and this system is operable to convert mechanical power provided by said powertrain into a form (SP) that can be stored by an energy storage element (22, 5), drawing energy stored by the energy storage element, and transforming the power drawn from the storage element into mechanical power. The powertrain is capable of transferring mechanical power to and from the electromechanical system. The energy storage element is coupled to said electromechanical system for exchanging power with the electromechanical system and is operable to store energy provided by the electromechanical system, and acts as ballast to stabilize system operation. A controller (23, 4) is provided for regulating powertrain mechanical power, regulating electrical power provided by the electromechanical system to other devices, and regulating the power transferred with the energy storage element in order to regulate the amount of energy stored in energy storage element.
