FEATURES

High performance and low fuel consumption

l The rocker arm reduces the valve-actuation torque as well as fuel consumption.

l Air-intake efficiency improved through the adoption of the optimum air-intake system layout.

l Improved response and fuel consumption has been achieved by electronic control multipoint

fuel injection.

l Water-cooled turbocharger. <Turbo>

Quiet operation

l Noise and vibration have been decreased by the adoption of roller rocker arms.

l Noise generated by the valve mechanism has been decreased by the hydraulic auto lash adjusters.

l Vibrations have been decreased by the adoption of bearing caps with beams which increase the

rigidity of the crankshaft support points.

Serviceability

l Complete self-diagnosis functions.

l Enhanced reliability through the adoption of gold-plated connector terminals.

l Use of an auto tensioner achieves maintenance-free, automatic adjustment of timing belt

tension.

l Use of the auto lash adjusters achieves maintenance-free, automatic adjustment of valve clearance

The

2coil

ignition system without a distributor supplies sufficient ignition energy even during

high speed operation.
