It took Honda an awful long time to get enthusiastic about the idea of diesel power. In fact, the 1.6-litre i-DTEC unit we're going to look at here powering this tenth generation Civic is actually only the second diesel the company has ever designed for the European market. It's been significantly improved for use in this tenth generation Civic model.
The enhancements include a reduction in cylinder friction, thanks to 'super plateau honing' of the bores to enable smoother piston movement. The 1,597cc engine uses the same advanced Bosch fuel injection system as before, and features a small, high-efficiency turbocharger, a low-pressure exhaust gas recirculation system and a high-intake flow, high-swirl cylinder head port. A high-strength, lightweight slender crankshaft and all-aluminium, open-deck, high-pressure, die-cast engine block minimise the engine's weight. For the new i-DTEC, additional cast ribs have been added to the cylinder block to increase structural rigidity and, consequently, improve the management of noise, vibration and harshness. It all sounds quite promising doesn't it?
