Lubrication System
Continuous Variable Displacement Oil Pump
The variable displacement oil pump is designed to have the ability to change its running displacement upon command. Working together with a pressure regulation proportional solenoid valve, it can vary its displacement to produce the required oil pressure without wasting energy through bypassed oil flow or excessively high oil pressure. Therefore, its power consumption is reduced for a better fuel economy, comparing to a fixed displacement oil pump.
The oil pressure in the control chamber is balanced by the force from the pump spring in a running pump. When a given duty cycle control signal is sent to the solenoid valve, it will command a given oil pressure. If the actual oil pressure is higher than the commanded oil pressure, the solenoid valve will supply more oil to the control chamber, produce more pressure in the chamber, push the spring and the eccentric ring down, and reduce its running displacement and the oil pressure till the pressure is at the commanded level. Or vice versa, if the actual oil pressure is lower than the commanded oil pressure, the solenoid valve will supply less oil to the control chamber or even vent the chamber, produce less pressure in the chamber, bring the spring and the eccentric ring up, and increase its running displacement and the oil pressure till the pressure is at the commanded level.
The required oil pressure, i.e. the commanded oil pressure, depends on the operation conditions of the engine. Therefore, the engine runs with oil pressure at its required level without waste in such a system in order to minimize its parasitic energy loss

Engine Oil Filter and Housing

| Item | Description |
|---|---|
| 1 | Oil filter housing assembly (includes oil filter reservoir and stem) |
| 2 | Oil filter |
| 3 | Oil filter housing-to-engine front cover seals (requires 2, included with service filter) |
| 4 | Oil filter housing stem-to-oil reservoir drain port seal (included with service filter) |
During oil filter removal and installation:
- The oil filter housing and stem must be inspected for damage including cracks or separation of the stem from the housing. If damaged, a new oil filter housing assembly must be installed.
- The 2 oil filter housing-to-engine front cover seals are included with the service filter and must be replaced to prevent oil leakage.
- The oil filter housing stem-to-oil reservoir drain port seal is included with the service filter and must be replaced. If this seal or filter housing stem is damaged or missing, the oil will flow through the reservoir drain port and a loss of engine oil pressure will occur.
Twin Independent Variable Cam Timing (Ti-VCT)
The twin independent VCT system allows variable control of the valves which optimizes combustion at full load providing improved power and low speed torque (broadening the torque curve) which enables variable valve overlap which provides better fuel economy and emissions and provides optimized cold start operation with improved exhaust emissions.
