From the Toyota website with the GXL lowdown-
"Mounted above the engine there’s an air-to-air intercooler
which cools the air going into the engine, by drawing cold
air through the bonnet scoop. So with cooler, denser air
going into the engine, you get more power out of it.
The intercooler also means increased reliability through
lower air intake temperatures. A cross over pipe draws
boost from one bank of cylinders to the other, for a
balanced turbocharging eff ect. There are also two fuel
coolers, to keep the fuel charge concentrated.
Electronic direct injection and water cooled ‘Exhaust
Gas Recirculation’ (EGR) help reduce emissions. Further
effi ciencies are gained by using lighter weight aluminium
alloy pistons which reduce friction. Of course with less
rotating weight, the engine revs freer and easier while
engine wear is also reduced. Roller rockers also reduce
friction improving fuel effi ciency and reducing wear.
This advanced V8 is also equipped with a catalytic
converter which optimises exhaust fl ow and further
reduces emissions. For longer life, the V8 features
Toyota’s fi rst ever oil scavenging pump which works together
with the primary oil pump. The aluminium cylinder heads
have been carefully heat treated for durability. Even the
engine block has been cast using a higher grade graphite
iron for greater strength but lighter weight. The crankshaft
has been engineered using a special high strength carbon
steel to reduce weight, while balance weights limit vibration
and noise. Also helping it run quieter is an advanced gear
and chain driven timing system.
So if you think an engine that gives you more power from
less fuel, while satisfying Euro IV emissions regulations
sounds too good to be true, better take one for a test run
and find out for yourself."
Cant find any mention of whether they're fitted with a DPF to meet Euro IV emissions standards or is this the last Cruiser that won't be fitted with them?
