This bulletin includes all of the technical information required by authorised repairers and new vehicle and replacement part distributors for the launch EB2of the third generation turbocharged engine, emission control standard Euro 6.4 (STELLANTIS internal standard or European standard EURO 6.E) for passenger vehicles.
This bulletin must be presented and distributed in each dealership of the network by each department manager :
Key information to be noted in particular.
CAUTION : Prerequisite : Refer to the bulletin "Commercial launch of the engines EB2 complying with the emission control standard EURO 6.1", bulletin available on the manufacturer’s aftersales documentation portal.
CAUTION : Prerequisite : Refer to the "Commercial launch of petrol engines that comply with the EURO 6.2 emission control standard" bulletin, available on the manufacturer’s aftersales documentation portal.
CAUTION : Do not use additives in the engine oil and only additives for fuel "UNIK" and "UNIK+" for petrol engines are compatible with the engines EB.
CAUTION : /!\ : Absolutely no versions and generations of the engines EB2 are compatible with the use of ethanol E85, including conversion kits. The use of this fuel and of these systems will cause premature wear and malfunctions which will damage the engine and will not be covered or accepted under the manufacturer’s warranty.
Engine range EB2 of generation 3 is offered in 4 engine bases.

2. Product description
To prepare for the future of petrol power train assemblies after 2022, STELLANTIS must replace the generation 2 turbocharged EB2 engines to comply with the new regulations in Europe and China and also to have an engine in Korea (SULEV30) to achieve objectives CAFE and CAFC.
To do this, STELLANTIS has developed a new generation of the turbocharged EB2 engine compatible with hybridisation (MHEV).
This engine is available in 2 power outputs : 136 ch for launch, then 100 hp.
For Europe, the engine is fitted with the STTd function : Stop and Start by starter motor function.
The Trémery manufacturing plant, in France, is the first factory on the 4 to manufacture and assemble this engine.
The EB2 LTD engine has been designed to meet the emission control standard EURO 6D FULL which has been in force since January 2021 and above all comply with standard EURO 6E which should come into force in January 2025.
For STELLANTIS, this engine :
This engine has been designed to cover a wide range of regulations, including :
Compared to the generation 2 turbocharged EB2 engine, the main differences are :
2.1. Achievement of the objectives of the emission control standard EURO 6.4 and reduction of emissions of CO²
The increasingly strict emission control standards have imposed the adoption of more precise technologies in the control of fuel delivery( This delivery is characterised by the air/fuel mixture richness).
To improve efficiency and save fuel, the following conditions are necessary :
The Air–Fuel Ratio (AFR) (true mass ratio of air to fuel) indicates the mass of air consumed per 1 grammes of fuel.
The lambda ratio is the ideal delivery to fuel delivery ratio and therefore is the opposite of the mixture richness.
The ideal delivery of 1 grammes of fuel for 14,7 grammes of air, also referred to as the "stoichiometric mixture", generates uniform and complete combustion, which creates low levels of pollution. This delivery ensures the best engine efficiency, resulting in lower fuel consumption but at the expense of power.
When the lambda ratio is equal to 1, power and fuel consumption are not optimal but offers better efficiency, uniform and complete combustion, and, above all, low emission of pollutants.
To achieve the objectives of the emission control standard, STELLANTIS has chosen the generation EB2 engine 3 :
Parts and assemblies affected :
The "central direct injection" system includes :
N.B. : A very fine droplet spray by the fuel injectors is produced by means of 6 holes made by a laser process.
The ignition system includes( per cylinder) :
2.2. Reduced fuel consumption
To reduce fuel consumption by 3 % compared to the previous generation turbocharged EB2 engine, a new combustion cycle has been incorporated.
The objective was achieved by using the MILLER combustion cycle, instead of the BEAU de ROCHAS cycle, combined with a higher combustion rate at 11,5 (instead of 10,5) and the operation of a new electrically controlled variable geometry turbocharger.
The compression rate increased to 11,5 is the result of a new combustion chamber design (cylinder head and piston).
Special work has been carried out to losses due to engine friction.
Parts and assemblies affected.

Timing front panel :
2.3. Engine performances
Depending on the engine version, the power has changed from 74 to 100 kW (100 at 136 bhp), slightly higher than the previous generation.
Torque is available over a wide range from 190 to 230 Nm, identical to the previous generation of EB turbocharged engine, with the aim of maintaining the best performance in this category.
In order to achieve these performance targets, the following conditions are necessary :
Parts and assemblies affected.
Air turbocharging :
N.B. : The world engines retain the fixed geometry turbocharger.
