1. Description
The tilt steering mechanism allows selection of the steering wheel position (in the vertical direction) to match the driver’s driving posture. The tilt steering mechanisms are classified Read more What is Tilt Steering Mechanism?

Suspension and Steering Camber
The front wheels of the car are installed with their tops tilted outward or inward. This is called “camber” and is measured in degrees of tilt from the vertical. When the top of a wheel is tilted outward, Read more Suspension and Steering Camber
Engine Auto Tensioner
Timing Chain Auto-tensioner
The timing chain auto-tensioner uses a spring and engine oil pressure to maintain proper tension at all times. It also suppresses noise from the timing chain. Using an internal Read more Engine Auto Tensioner
ESA (Electronic Spark Advance)
The engine ECU, which receives signals from various sensors, calculates the ignition timing and transmits ignition signals to the igniter. The ignition timing is calculated continuously in accordance with Read more ESA (Electronic Spark Advance)
Spark Plug
The high voltage generated in the secondary winding of the ignition coil produces a spark between the center and ground electrodes of the spark plug in order to ignite the air-fuel mixture that is compressed Read more Spark Plug
Engine Piston Ring
1. Description
The piston ring is designed to prevent pressure from leaking out of the gap between the piston and the cylinder. There are three piston rings that function to keep the combustion chamber Read more Engine Piston Ring
Platinum/Iridium-tipped Plug
On the platinum-tipped and iridiumtipped spark plugs, the center electrode and the opposing ground electrode are covered with a thin platinum or iridium tip. Therefore, these spark plugs provide a longer Read more Platinum/Iridium-tipped Plug
Engine Valve Mechanism
The valve mechanism opens or closes the intake valve and exhaust valve at the proper timing in order to draw the air-fuel mixture into the cylinder and discharge the combustion gas into the outside.
Ignition Performance
The following factors affect the ignition performance of a spark plug:
1. Electrode shape and discharge performance
Rounded electrodes make discharging difficult, while squared-off or pointed electrodes Read more Ignition Performance
Engine Scissors Gear Mechanism (Sub-gear Mechanism)
There is a scissors gear (sub-gear) on the driven gear of the camshaft for the compact DOHC which serves to reduce gear noise associated with changes in torque. The sub-gear is pushed toward the rotational Read more Engine Scissors Gear Mechanism (Sub-gear Mechanism)
