Toyota introducing diesel powered Lexus
Toyota has introduced its first diesel powered Lexus model. The new
Lexus IS, unveiled at the Geneva Motor Show, comes with two engine
options: a 2.5 liter V6 gasoline engine, and a 2.2 liter diesel. The
vehicle is intended for the EU market.
The new 2,231 cc common rail diesel unit is constructed entirely from
aluminum. It features a variable geometry turbocharger and a piezo
common rail injection system, capable of up to 4 separate injections
per cycle. High injection pressure of 1,800 bar is combined with--
according to Toyota--the world's lowest diesel engine compression
ratio of 15.8:1, which facilitates quiet combustion and lower NOx.
The engine generates 130 kW/177 hp at 3,600 rpm and 400 Nm/295 lb-ft
of torque between 2,000 and 2,400 rpm. It is the same engine--the
production of which was just started by Toyota in Poland--that was
recently introduced in the new Toyota Avensis.
The new 2.2 liter diesel is also equipped with "Lexus Clean Diesel
Technology", the integrated NOx adsorber/particulate filter emission
package, which was called "D-CAT" and/or "DPNR" in the Avensis model
(the durability of the NOx adsorber in the DPNR system was recently
questioned by German car makers, see DieselNet Update - February
2005).
