Visto l'interesse per il 1.2 TCE, vi giro un estratto da un comunicato Renault che avevo recuperato quando stavo scegliendo la macchina.
Se a qualcuno può interessare....
"Punch, response and power under the right foot thanks to turbo technology
Developed from the 1.2 16V 75hp block, it is equipped with a low inertia turbo that ensures
minimal lag thanks to its small diameter turbine and compressor. Its maximum power of 100hp
and peak torque of 145Nm are available at 5,500rpm and 3,000rpm respectively. The marriage
of a small cubic capacity and a low inertia turbo ensures lively response from low revs, while
maximum torque is available from low engine speeds and remains available across a broad revband.
The turbocharger includes an "overpower" feature which temporarily boosts power output
in 2nd, 3rd and 4th gears at engine speeds of more than 4,500rpm (5hp extra power and 6Nm
extra torque).
Some 30 per cent of the TCE 100hp's components are new compared with the 75hp block. The
new engine also benefits from several evolutions, notably sodium cooled valves for enhanced
resistance to heat, oil jet-cooled pistons and optimized cylinder head cooling. The injectors,
sparkplugs and coil are all specific to the TCE 100hp, while its sump is made from aluminium.
The four-into-one exhaust manifold has been carefully designed to optimize the flow of exhaust
gases in order to maximize the delivery of energy to the turbine. Meanwhile, a tumble-effect
movement of the air inside the cylinders favours combustion speed for enhanced chamber-filling
efficiency and improved stability at idle.
A fuel efficient, environmentally-friendly engine
With a cubic capacity of 1,149cc, this small engine enables Modus, New Twingo and Clio III to
claim record combined cycle fuel consumption of 5.9 litres/100km, a figure to which its low idling
speed of 650rpm contributes. ^
With CO2 emissions homologated at 140g/km, the TCE 100hp engine will also contribute to the
"CAFE 2008" commitment made by Renault to be selling one million vehicles with CO2
emissions of less than 140g/km by 2008. This engine is also a response to the anticipated
demand for petrol engines compared with small diesels when the Euro5 standard comes into
effect in Europe. The TCE 100hp is coupled to a manual five-speed gearbox. It is produced in
Douvrin, (France) which has a weekly production capacity of 13,500 1.2-litre engines. Renault
invested 80 million euros in its development."
ma non sai, forse, che il nostro amico romano è un esteta, per questo, avendo sempre letto in passato della mascherina, ho supposto che credesse fossero anche più belli
