Summary
Honda has developed a 3rd-generation diesel engine, seeking to balance further CO2 reductions with dynamic performance. This development focused on downsizing the engine and succeeded in developing a compact, lightweight and high-efficiency 1.6 L in-line 4- cylinder turbocharged i-DTEC diesel engine. Optimization of engine rigidity in the newly developed 1.6 L diesel engine has made it possible to use an aluminum cylinder block with an open-deck structure. Furthermore, weight could be reduced by means of an efficient structure and engine layout. In addition, mechanical friction has been minimized via reducing weight of the reciprocating components and downsizing auxiliary equipment. These innovations made it possible for the engine to achieve the same level of friction as a Honda petrol engine of the same displacement.
