The engine comprises a cylinder block which is closed by a cylinder head (1) obtained by a moulding process. The engine is secured to the chassis of the vehicle by way of an intermediate support (2) which is connected directly to the cylinder head (1). The intermediate support (2) is in one piece with the cylinder head (1) and the unit formed by the cylinder head (1) and the intermediate support (2) integrated into the cylinder head (1) is obtained in one and the same moulding operation, such that in this way the interface between the cylinder head (1) and the intermediate support (2) is eliminated. Motor vehicles. Internal combustion engines of motor vehicles. Securing of engines on the chassis of vehicles.

The invention relates to a method for calculating a guideline for adding a reducer fluid, via an appropriate adding means (5), into an exhaust line of a combustion engine (1). Said method is characterized by the following steps: assessing the pressure in the exhaust line at the point where the reducer fluid is added; assessing the pressure of the reducer fluid at the inlet of the adding means (5); and calculating the adding guideline on the basis of the pressure within the exhaust line and the pressure of the reducer fluid.

The invention relates to an active beater for reducing vibration in a mechanical structure, of the type comprising a mobile mass in linear translational reciprocating movement along an axis of movement (D), characterized in that it comprises a balancing piece having a flyweight (11) offset from the axis of movement. The invention also relates to a motor vehicle fitted with such a beater.

The invention relates to a method for desensitizing the air flow Qair entering the cylinders of a heat engine provided with an EGR loop, that is desensitizing in relation to variations DeltaQegr of the gas flow Qegr passing through the EGR valve. According to said method, maximum admissible variations DeltaQegr are determined for points of stabilised operation of the engine; admissible effective section variations DeltaSeff are determined according to the variations DeltaQegr; the required progressivity of the EGR valve is determined according to the admissible effective section variations and the performance of the control system; and said required progressivity is compared with the characteristics of the EGR valve. The points of stabilised operation or the EGR valve itself are modified in such a way as to obtain a correlation between the required progressivity and the characteristics of the EGR valve.

The invention relates to an intake module (100) for a combustion engine, which includes a wall (101) having an outer surface (102) and an inner surface (103). The inner surface (103) at least partially defines an intake path (104) into the intake module (100) through which air can be brought to a cylinder (105) in the combustion engine. The outer surface (102) of the wall (101) includes a projection (106) defining a drilling axis (107) oriented from the outer surface (102) towards the intake path (104).
