Returnless Multi-Pressure-Level Fuel Injection System
September 15, 2015
The following Returnless Multi-pressure-Level Fuel Injection system is protected by U.S. Patent #7,318,414, Canadian Patent #2,485,599, U.S. Patent #7,775,191, Japanese Patent #4,808,400 and pending foreign patent applications. TMC Fuel Injection System, LLC, incorporated in the State of Delaware, has been established for intellectual property of the Returnless Fuel System and business matters in America.
The fuel injection system setting pump at a predetermined substantially constant speed can instantly create multi-pressure levels by partially disposing fuel from main fuel line upstream of fuel rail to fuel tank, through at least one fuel by-pass line with flow restraint, creating off-line fuel recirculation loops to stabilize fuel pressure of entire fuel system. A binary control valve is used to select proper pressure level in four off-line configurations. The system operates under high pressure in highway driving with power; under low pressure in city driving to save fuel and reduce exhaust emissions when gas pedal is released including idle. The same system can instantly deliver additional fuel on-demand producing super power beyond engine rating for a sport-car-like performance.
Software setting limits and manual override by-pass are used to safeguard super power operation preventing uncontrollable runaway. When engine fuel demand exceeds injection dynamic range at a given pump speed in a system, fuel pump can be set at another predetermined substantially constant speed allowing automaker greater choices to set additional pressure levels extending dynamic range for superior performance.
