Renault's Euro 3 engine

Flexible injection systems allowed Renault VI engineers to balance many conflicting priorities in developing Europe's first heavy-duty diesel engine with a fully electronic high-injection-pressure common-rail injection system.

Customer power requirements for the European long-haul segment are now above 280 kW(375 hp) and are increasing continuously, consistent with the demands of the North American market. Fuel consumption plays an important role in the profitability of trucking companies. It, therefore, is a major competitive issue between truck manufacturers, especially in Europe.

With fuel consumption and exhaust emissions driving demand, truck manufacturer Renault VI has designed a completely new engine with full electronic injection to meet Euro 3 emissions standards. These standards call for 5 g/kW·h oxides of nitrogen (NOx), 2.1 g/kW·h carbon monoxide (CO), 0.66 g/kW·h hydrocarbons (HC), and 0.10 g/kW·h particulate matter (PM). The new technology also allowed the company to satisfy demands for high output, producing 300 kW (400 hp) and 1800 N·m (1327 lb·ft).
