<4A9>
The newly-developed 4A9 engine has been installed
to realise small-size, light-weight, high-performance,
and better fuel economy with the state-of-the-art
technologies such as the aluminium die-cast cylinder
block, direct attack driven-type DOHC MIVEC, timing
chain-type cam drive, and rear exhaust.

The A TF warme r (A TF cooler) is adop ted for the
mode ls with 4A9 en gine. (the A TF cooler incorporat
-
ing the radiator is no t adopted)
At the start of runn ing, the tempe rature of th e engine
coolant rises earlier tha n that of the AT F. The A TF
war mer ut ilizes this ch aracteristic to raise the ATF
tempe rature a s ea rly a s po ssible to an a ppropriate
leve l (70
−80 °C). It also co ntrols flu id tempera ture st
ably and reduces A TF agitation resist ance to
imp rove f uel consump tion ra tio.
In addition , a thermo-valve has bee n adopted to
restrict the eng ine coolant supply to the A TF warmer
(A TF coole r) until the engine co olant temperature
reach es th e appro priat e temperature when low tem
-
perature start in winter , giving the priority to th e heat-
ing performance .
