PSA Peugeot Citroën inaugurated the production line for the new EB Turbo PureTech engine at the Française de Mécanique plant in Douvrin, northern France on 29 October 2012. The new three-cylinder petrol engine combines compact dimensions and light weight with breakthrough performance for the capacity level.
PSA Peugeot Citroën used a three-cylinder architecture and a range of technologies to meet demanding technical specifications and ensure outstanding at-the-wheel pleasure:
The EB Turbo PureTech engine will initially be fitted on the Citroën C4 (110 g/km of CO2) and the Peugeot 308 (105 g/km of CO2) in March 2014, followed by the Citroën C3 and DS3 (105 g/km of CO2) in July 2014.
Performance though downsizing. The EB Turbo engines were designed with a high specific performance level to increase yield while reducing capacity. The engines stand as PSA Peugeot Citroën's finest achievement thus far in downsizing and illustrate the Group's extensive know-how in direct-injection turbo engine production (the EP 1.6 l THP engine has won seven awards in the category). The EB Turbo PureTech 1.2 l engines will reduce CO2 emissions by 18% compared with today's 4-cylinder engine, while providing true driving pleasure thanks to generous torque at the lowest engine speeds.
Using a new-generation, high-yield turbo (240,000 rpm), the EB Turbo PureTech unit strikes an ideal compromise between low-speed torque and power, with 95% of torque available from 1,500 rpm through to 3,500 rpm.
The combustion system was honed to fully capitalise on the engine's technologies, including the adoption of centrally positioned, high-pressure 200 bar direct injection. The position of the injector, the shape of the spray (thanks to laser technology), the management of injection pulses (up to three injections per combustion) and the injection pressure (up to 200 bar) ensure optimal spraying in the combustion chamber, the result being the best combustion possible. Fuel consumption and pollutant gas emissions were cut drastically by optimising the internal aerodynamics of the combustion chamber and using a variable intake and exhaust timing system.
The engine architecture and technologies feature the tried-and-tested choices used on the normally-aspirated EB model that set a new standard in the segment. One of the key objectives was to limit mechanical losses through friction, which account for roughly 20% of the power consumed. This objective was met by adjusting the size of the crankshaft, offsetting the cylinders and using a lubricated timing belt.
A diamond-like carbon (DLC) coating was used on the piston pins, rings and push rods to reduce friction. The oil pump is controlled electronically to provide the optimal amount of lubrication.
The result? Friction is a full 30% lower than on the top competing engine. The EB PureTech family is now the standard-setting engine in the segment.
PSA Peugeot Citroën has invested a total €893 million in the EB PureTech engine family as a whole:
With 65% of resources purchased from French suppliers, or 50% of the investment, the new generation of engines is a major priority for the Group and for France's industrial fabric.
Series production is set for launch in March 2014 with an annual output capacity of 320,000 units. The new 3-cylinder engine is efficient, clean, compact and modular.
The new engine will be manufactured in France to be fit on vehicles assembled in PSA Peugeot Citroën automotive plants in Europe. Starting in 2015, it will also be produced in China for the local market. It will be a considerable asset in the Group's international expansion.
Featuring the finest environmental technologies, the engine will enable PSA Peugeot Citroën to strengthen its leadership in low-emissions vehicles.
