engine versions of Honda’s UK-built Civic three and five door hatchback models
will make their world debut at the Frankfurt Motor Show next month.

The Isuzu-sourced 1.7-litre turbodiesel has common rail direct injection and
variable nozzle turbocharger and accelerates the three-door version from 0 to
100km/h (62 mph) in 11.2 seconds. EC combined cycle fuel consumption is 57.7

Power output is 100 PS at 4400 rpm and peak torque of 220 Nm is delivered at
1800 rpm. The DOHC, four-valves-per-cylinder engine features a number of items
unique to Honda including the fuel filter and accelerator position sensor.



Additional NVH measures for the diesel include an engine undercover, thicker
urethane foam insulation in the front bulkhead area, thicker floor mat insulators
and noise-absorbing felt backing on the fascia.

The engine itself features a high-performance acoustic cover, a dual damper-type
crank pulley and a higher inertia flywheel.

The diesel Civics, badged 1.7 CTDi, share liquid filled mounts attached to
either side of the sub-frame with their petrol siblings – one for the transmission,
the other for the engine. These minimise the transfer of engine vibration, particularly
at idle.

Honda says that the compact dimensions of the Isuzu engine were a significant
factor in its selection for the Civic because it fits in the confines of the
model’s ‘short nose’ design.

The Isuzu diesel is matched to a unique five-speed manual transmission with
ratios optimised to the engine’s characteristics. A triple cone synchroniser
between first and second gears ensures smooth shifting.

High strength, shot-peened gears are used, and despite the need to cope with
high levels of torque, the gearbox is compact; at 359.5 mm, it is just 7.5 mm
longer than the manual transmission of the 1.4 and 1.6 litre petrol engine cars.

Diesel vehicles accounted for one third of Western Europe’s C-segment
three door hatchback sales during 2000, compared with a fifth in 1997.
