CYLINDER BLOCK
System Characteristics
• Rib design by considering strength against engine
vibrations and weight
• Cambering type skirt design on case housing wall to
reduce the engine noise
• Water jacket design to increase the cooling efficiency
of cylinder bore bridge
• Deep head bolt thread to prevent the deformation at
cylinder bore surfaces
• Reinforcement of strength
- Main bearing housing / Main bearing cap
- Extended main bearing cap bolt
• Reducing the noise, vibration and harshness (NVH)
- Minimize the vibration by adding external ribs
- Adding the ribs around oil pan parting surface

Knock Sensor
Two knock sensors are located on the cylinder block (intake manifold side).
To detect engine vibration under abnormal combustion, knock sensor has piezoelectric element fixed on the
vibration plate and this vibration plate is fixed on the base. If happens knocking, pistons or connecting rods
vibrate and occurs heavy sounds that hit metal. Knock sensor is used to detect those knockings caused by
abnormal combustions. It controls idling stabilities and turns on the engine warning light when detects injector
damages. And also controls pilot injection very precisely during MAP learning.
When knock sensor is defective, engine ECU corrects injection timing based on MAP values like engine speed,
intake air volume and coolant temperature.
Before checking the knock sensor unit, be sure to check the tightening torque of the sensor and connector
connecting conditions.
