Valve Train
The valve train uses Direct Acting Mechanical Buckets (DAMB). The camshaft lobes are positioned directly above mechanical buckets which are positioned on top of the valves.
Ti-VCT
The Ti-VCT system allows variable control of the valves closing 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.
Switchable Engine Mounts
The switchable engine mounts are a hydro dampening design to improve engine vibration at idle.
The switchable engine mounts consists of:
2 glycol filled engine mounts.
Vacuum reservoir and vacuum solenoid switch mounted on the drivers side of the engine compartment frame rail.
Vacuum hoses with check valves.
Vacuum On trigger is set when all three conditions are satisfied:
Vehicle speed is below 20 MPH (drive) or vehicle speed is below 10 MPH. (reverse/neutral/park).
Engine speed is between 360 RPM and 860 RPM.
Run Time greater than 1.5 seconds.
Vacuum OFF trigger is set when:
Engine speed is greater than 960 RPM.
Engine speed is less than 260 RPM.
Vehicle speed is greater than 22 MPH.
