A closed loop performing a Rankine cycle for a motor vehicle includes a circulation and compression pump for a working fluid, a heat exchanger swept by a hot source for heating said working fluid, expansion means for expanding the hot fluid and a cooling exchanger-swept by a cooling fluid for cooling this working fluid. A method of controlling the closed loop performing a Rankine cycle for a motor vehicle includes, after detecting a vehicle accident situation, in communicating the inside of the loop with the ambient air.

Method of controlling, after detecting a vehicle accident situation, throttling means for an opening provided on a closed loop performing a rankine cycle and loop using same for communicating an inside of the closed loop with ambient air outside the closed loop

The present invention relates to a device for controlling the working fluid with low freezing point circulating in a closed circuit () operating according to a Rankine cycle, said circuit including a compression pump () for the fluid in liquid form, a heat exchanger () swept by a hot source () for evaporation of said fluid, an expander () for expanding the fluid in vapor form and a cooling exchanger () swept by a cold source (F) for condensation of the working fluid. According to the invention, the device includes a fluid collection tank for draining said circuit.

A method for controlling a supercharged engine, that includes determining an overlap of valves by opening a supercharged non-fuel-containing air inlet valve and closing an exhaust valve before the exhaust phase of an engine cylinder and in the vicinity of the top dead center (TDC), actuating a blocking means for blocking a supercharged non-fuel-containing air intake means to admit supercharged air flowing in the supercharged non-fuel-containing air intake means into a chamber to scavenge residual burned gases when a pressure of the supercharged non-fuel-containing air is greater than a pressure of the exhaust gases, and actuating the blocking means to shut off the supercharged air flowing from the supercharged non-fuel-containing intake means into the chamber when pressure of the supercharged non-fuel-containing air is less than pressure of the exhaust gases.

Method for controlling a supercharged engine, particularly an indirect injection engine, and engine using such a method

A combustion method for a supercharged four-stroke engine having at least four cylinders includes a combustion cycle during which a cylinder of the engine is in the exhaust phase while another cylinder is in the supercharged air intake phase with a burnt gas scavenging stage. The start of the exhaust phase of the cylinder in the exhaust phase is shifted in relation to the start of the burnt gas scavenging stage of the cylinder in the intake phase.

Supercharged four-stroke engine combustion method and engine using such a method

The present invention relates to a supercharged internal-combustion, notably indirect-injection engine comprising at least one cylinder () with two types of supercharged air intake means (), one type for non-carbureted supercharged air intake () and another type for carbureted supercharged air intake (), said intake means being supplied with supercharged air by supply means (). According to the invention, supply means () comprise a specific supercharged air supply device () for each type of intake means ().
