Study no. 1: Reducing emissions for toxic substances

The study was carried out on a direct injection diesel engine (1896 cm³, 66 KW at 4,000 rpm). Three journeys were considered: 3.2 km, 15 km and 34 km with an ambient temperature of +25°C. Pollution and total consumption weighted without a engine heater with an outdoor temperature of 25°C. CO emissions (g/km) HC emissions (g/km) Consumption (litres/100 km) For 3.2 km 0.131 0.794 5.87 For 15 km 0.042 0.184 5.21 For 34 km 0.024 0.084 4.97 Pollution and total consumption weighted with a Carlor engine heater at an engine temperature of 50 °C.
