INVERTED FUNCTION TURBOCHARGER * or  IFT* :

INTAKE VALVE CARBON BUILD-UP:  
a problematic condition affecting UAIC  (uncontrolled air Intake cycle engines)  affecting direct fuel injection Otto cycle I.C.E.  either C.I.  (diesel) or S.I. direct (gasoline) fuel injection system
stratified charge or homogeneous charge fuel system that injects fuel directly into the cylinder and therefore does not permit any fuel spray to flow and clean deposits that can have collected
on backside of intake valves creating troublesome air flow disturbances from intake valve carbon build-up possibilities. Accumulation of carbon-deposits build-up on intake valve's backside
negatively affects the critically important smooth air-flow in the cylinder and disrupts air-fuel optimized critical atomisation charge mist increasing raw emissions as well as specific fuel
consumption.  This problem can be more prevalent with larger displacement S.I. Otto cycle ICUA engine strategy and negatively affects engine operation and emissions of direct fuel injection
system since no fuel passes over to clean the carbon deposit accumulated on the intake valves to clean them. Conventional PCV system  allow crankcase oil vapour mist and combustion
blowby  vapours to be carried over back to the intake valve ports to deposit on the backside of the intake valve after the engine has been frequently operating at critical sustained light-load
operating conditions* . The solution requires more frequent and more strictly enforced oil change schedule to alleviate this condition. Otto cycle LTCev CAIC and NCAIC engines are more
robust in this regard, and immune to this problem insuring long term dependable trouble-free required operation. (refer to:

MILD-HYBRID: essentially conventional fossil-fuel vehicles equipped with one motor/generator in a parallel configuration) allowing the engine to be turned off whenever stopped, yet restart
quickly. Mild hybrids may employ regenerative brake some level of power assist to the I.C.E.  but mild hybrids do not have an exclusive electric-only mode of  propulsion.


MILD-HYBRID Assist-Mode: essentially an assistance mode for conventional fossil-fuel MILD-HYBRID vehicles equipped with an electrically assisted inverted function turbocharger can allow
the engine to be turned off yet to be able to restart quickly just as a MILD-HYBRID.

Mini-Hybrid typically employ electric assisted IFT to assist an CAIC strategy ICE whenever a vehicle must remain in motion and move slowly at very light engine load either at idle or just above
engine idle speed. Useful for working utility vehicles (pick-up) and for personal marine craft (day cruiser) during docking manoeuvres.

V,
VVICC*:  Variable Volume Individual Cylinder-Crankcases: are individual crankcase's dry-sump partitions  for turbo compound pneumatic coupling requirements
smaller volume dry-sump partitions of the crankcase housing for the crankshaft & connecting rods, they are pneumatically distinct and separated from the usual larger wet-sump crankcase
housing of an engine oil (Oil sump). The unique wet-sump/dry-sump (patented) LTCev engine crankcase configuration insures special considerations to only allow minimal stray oils droplets in
the evacuated air from the dry-sump to enter the IFT , before entering into neightboring VVICC.  Note:LTCev's VVICC are somewhat similar to two cycle engine multiple cylinder's crankcase's
partitions.
