| 20090273459 | TACHOMETER AND GEAR INDICATING APPARATUS - An apparatus for a vehicle having a multi-gear transmission includes an analogue tachometer display device indicating by continuously displacing a pointer against a graduated scale the number of revolutions per unit of time of a vehicle engine; a computer processing unit CPU receiving input signals representative of the actual engine speed and of the actual vehicle speed and determining at least one forecast engine speed corresponding to the actual vehicle speed, based on at least one speculated transmission gear ratio; and a gear indicator display adjacent to the graduated scale on which a current gear figure corresponding to the currently engaged gear is digitally displayed next to the current position of the pointer, and a speculated gear figure corresponding to the at least one speculated gear is digitally displayed next to the corresponding forecast engine speed on the graduated scale. The apparatus can incite to engage the optimum gear which is achieved by displaying not only the optimum gear but also the consequence on engine speed of engaging the optimum gear. | 11-05-2009 |
| 20090199582 | Air Conditioning System Operating On A Supercritical Cycle For Use In Motor Vehicles - An air conditioning system operates on a supercritical cycle for a vehicle and includes a circuit through which a refrigerant flows, which circuit includes an evaporator where the refrigerant collects heat from the ventilation air to be conditioned, a compressor, a cooler where the refrigerant releases heat into the outside air, an expander, and an arrangement for humidifying the outside air that contacts the cooler. The system has no internal heat exchanger. | 08-13-2009 |
| 20090173060 | EXHAUST GAS CONTROL APPARATUS - An exhaust gas control apparatus is provided for an internal combustion engine having at least two cylinders, a turbine, and an exhaust manifold collecting a flow of exhaust gases formed in each cylinder towards the turbine. The exhaust manifold has an inlet port connected to each cylinder and an output port upon which the turbine is secured. The exhaust gas control apparatus includes at least one seal positioned between two adjacent inlet ports, each seal being articulated relative to the exhaust manifold and being capable of sealing one of the two adjacent inlet ports to reduce the internal volume of the exhaust manifold available for the flow of exhaust gas. The apparatus of the invention makes it possible to reduce the internal volume of the exhaust manifold according to the engine cycle. By doing so, most of the kinetic energy of the exhaust gases is channelled towards the turbine; this is in contrast with a traditional exhaust manifold whereby a part of the kinetic and thermal energy of the exhaust gases is dissipated within the internal volume of all the inlet ports of the exhaust manifold. | 07-09-2009 |
| 20090090336 | INTERNAL COMBUSTION ENGINE AND EGR HEAT EXCHANGER FOR IT - Internal combustion engine wherein a cooling medium inlet of an EGR (Exhaust Gas Recirculation) heat exchanger is fluidly connected to a turbine outlet of a turbocharger so as to use the exhaust gas outputted by the turbine as a coolant. | 04-09-2009 |
| 20080312792 | Drive Assisting Method for Reversal Path with Drawn Vehicle - The invention relates to a drive assisting method for the reversal path of a vehicle which consists of a tow track and a trailer pivotable with respect thereto and is provided with a conventional mechanical steering device. The inventive method consists in selecting a target point (C), which the vehicle path should pass through, Determination in calculating the steering angle instruction β | 12-18-2008 |
| 20080308353 | Lubrication System and Internal Combustion Engine Comprising Such a System - This lubrication system includes a pump feeding a main line which provides oil to a support interface for a crank shaft of oil engine and an auxiliary line connected to at least one piston cooling jet. The pump is a variable flow pump controlled on the basis of oil pressure in the main line. A proportional means is mounted on the auxiliary line. This means is adapted to control oil flow in the auxiliary line depending on the working conditions of the engine, e.g. oil temperature, torque to be delivered or rotational speed of the engine. | 12-18-2008 |
| 20080258472 | Method of Controlling Power Supply to an Electric Starter - The invention relates to a method of controlling the power supply to an electric starter that drives heat engine of a vehicle, in which the starter power supply is stopped after each supply phase for a first pre-determined period T | 10-23-2008 |
| 20080223333 | Control Method For the Intake and Exhaust Valves of and Engine and Internal Combustion Engine Comprising Such Valves - This method is for controlling the intake and exhaust valves of the cylinders of an internal combustion engine which is capable of operating either in four-stroke positive mode or in two-stroke braking mode. The control means pilot the valves so that at least a first exhaust valve of each cylinder ( | 09-18-2008 |
