После проверки давления дополнительного насоса, проверен "первичный" и "основной" топливный фильтры: |

и результат "на лице" как и запах. Понятна грусть этого японского парня при такой их загрязненности (35 тыс. км по Украине - это "что-то" :-)
Для реализации столь заявленных производителем технических характеристик (см. табл.), необходимо, как минимум, регулярное ТО (Regular SERVICE).

После замены фильтров и промывки (Wynn's) топливной магистрали, Gasoline High Pressure Fuel Pump и форсунок - автомобилю значительно полегчало.
As writed Toyota:
"Toyota launched the Toyota direct-injection D-4 gasoline engine as a fuel efficiency improvement measure in 1996. It was further improved to be adopted for use in the new Crown.
In addition, a high-pressure slit nozzle, which spreads atomized fuel in a fan shape during formation of the fuel-air mixture, was developed and has served as central technology for lean burn engines. The 3.0-liter D-4 (2JZ-FSE) engine achieved fuel efficiency of 11.4km/liter (according to the fuel test in 10-15 mode), which is in the top level in its class, and already meets the new fuel efficiency standards set to go into effect in 2010...".
