Abstract (en)
[origin: GB2436855A] A combustion apparatus such as a diesel engine (16) has an air inlet system (20,22) through which air can be drawn air from the atmosphere to the engine, a fuel supply system (28,30,32) for supplying fuel to the engine, an exhaust system (34,36,38,40,42) for exhausting combustion gas from the engine to the atmosphere and an exhaust gas recirculation system (44,46) for feeding a proportion of the exhaust gas from the exhaust system to the air inlet system so as to reduce NO and NO2 emissions by the engine. A heat exchanger (48) is provided between the exhaust gas recirculation system and the fuel supply system so that, in use, heat is transferred from the recirculating exhaust gas to the fuel not only so as to cool the recirculating exhaust gas and thus enhance the reduction of NO and NO2 emissions but also so as to warm the fuel and thus improve the combustion efficiency of the engine. In a front-engined motor vehicle, the heat exchanger can conveniently be disposed beneath the vehicle so as not to take up space in the vehicle's engine compartment.
