Abstract

A combustion apparatus such as a Diesel engine (16) in a motor vehicle (1) 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, and an exhaust system (34, 36, 38, 40, 42) for exhausting combustion gas from the engine to the atmosphere. A heat exchanger (48) is provided between the exhaust system and the fuel supply system so that heat is transferred from the exhaust gas to the fuel so as to warm the fuel and thus improve the combustion efficiency of the engine. When applied to a conventional layout of motor vehicle the heat exchanger can conveniently be disposed beneath the vehicle away from the engine compartment so as not to cause overcrowding thereof. The heat exchanger may form part of an EGR system (44, 46) for feeding a proportion of the exhaust gas from the exhaust system to the air inlet system so as to cool the recirculating exhaust gas and thus enhance the reduction of NO and NO2 emissions.
