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

General Information

The front suspension has a simple construction, the

McPherson strut type independent suspension featuring light unsprung weight. The front Suspension has the following features:

l Excellent driving stability, thanks to the

“antidive” geometry.

l Excellent braking stability, thanks to the

negative-offset geometry.

ANTI-DIVE GEOMETRY

Ordinarily, when the brakes are applied, the load is moved toward the front of the vehicle as the result of inertial force, and this causes the phenomenon known as “nose dive”, in which the front of the vehicle is caused to tilt forward and downward.

For this front suspension, however, the suspension link design

-which has a high arm is tilted forward in order to counteract the “nose dive” phenomenon. In other words, braking force F is divided into force components F, and the front spring, with an effect that reduces the “nose dive” phenomenon.

NEGATIVE-OFFSET GEOMETRY

For negative-offset geometry. the king pin offset angle is outside the center point of tire-to-ground contact. Thus, for example, if a tire on the right side

is punctured during driving, or if the brakes are applied while the left tires are on a slippery surface

(ice, etc.), the vehicle would be inclined to swerve to

the side (in this case the right side) of greater road

surface resistance to the tires, but, because of the

negative-offset geometry construction, a certain force would be generated to cause rotation in direction C, employing point A as the fulcrum point. At the same time, there would be generated at the tires on the opposite side a corresponding force to

cause rotation in direction D, also employing point A

as the fulcrum point, but, because that force is

greater in direction C (where road surface resistance is greater), the tires themselves will tend to turn in the left direction. As a result,. because

t.he

tires automatically countersteer in the left direction, even though the force applied to the vehicle by the road surface resistance is to the right, the system thus functions to maintain the vehicle on a relatively straight-ahead course.

NOTE The king pin offset is the distance from the center point of tire-to-ground contact when a line (extended to the road surface) is drawn to connect the

ball joint center point and the center point of the strut upper installation part.

OFFSET SPRING

Because struts are installed at an angle, the road surface reaction force to act vertically upon the tyre centre, and that force tries to bend the strut toward the inside of the vehicle. When this happens, the force trying to bend the strut toward the inside of the vetiicle acts upon the strut bearing component as bending moment

reaction force FL (because the upper part of the strut is fixed in place), thus increasing the friction of the bearing, and, as a result of the bending of the strut,

amplifying the moving resistance of the shock

Offset Spring

Ro2EMA

Then, because the coil spring is installed so that

its

centre is greatly offset (toward the outside of the vehicle) from the centre of the strut, the counteractive force for the spring tends to become great toward the outside of the vehicle, thus resulting in the generation of bending force FL opposite to the

bending of the strut, and thereby decreasing the friction applied to the strut bearing. As a result, the shock absorber’s internal movement friction is reduced, thereby improving riding comfort as well as the durability of components.

LOWER ARM

The lower arm is an A-type arm, and is connected, via a rubber bushing, to the crossmember. The rod bushing is optimum tuned, including the spring constant of the arm bushing, to provide
