A fuel injection system for a multibank engine having separate intake manifolds and throttle valves for each bank. Separate manifold pressure sensors for each bank are employed to determine injection signals for corresponding cylinders within each bank.
A seat for receiving a fuel injecting valve, is provided in an intake pipe at a portion closer to an intake port, than a straight line connecting a crossing point P, of a first and a second center lines CL, and CL, to a curved center C. of the bent pipe portion; fastening seats and for fastening the mounting member, to the intake pipe, is provided on the intake pipe, at such a position as to put the straight line between the seat and the fastening seats and; and the seat and the fastening seats and are formed in parallel to each other.
An engine throttle valve linkage includes an improved construction that can be placed in a space around an engine in an internal cavity of a protective cowling so as to control throttle valves under a synchronized condition. In a preferred mode, the engine includes first and second air intake conduits communicating with combustion chambers in the respective cylinder banks of the V-shaped engine and extending generally along side surfaces of the engine body. The first and second intake conduits have first and second throttle valves, respectively, both regulating an amount of air flowing through the respective intake conduits. A manipulator actuates both the first and second throttle valves. The manipulator includes a pair of manipulating members coupled with the first and second throttle valves. The manipulator is disposed generally between the first and second air intake conduits so as to be positioned on the engine body.
An improvement in liquid measuring apparatus and method of the type in which a desired amount by weight of a liquid is measured by the placement of a corresponding volume of liquid in a liquid metering chamber compensates for changes in the density of the liquid resulting from variations in the temperature of the liquid in the metering chamber by selectively operating one or more of a plurality of separate incremental volume elements to establish changes in the volumetric capacity of the metering chamber in predetermined increments of volume corresponding to the predetermined volume of each of the selected separate incremental volume elements, the improvement further including selectively dispensing one or more fractions of the total amount of liquid in the liquid metering chamber to dispense the desired amount of liquid.
An engine control system that is configured to be attached to the intake port or intake manifold of a reciprocating engine. The system can be designed to allow installation as original equipment or as a retrofit unit. In either case, the system provides the engine with a dual ignition and electronically controlled fuel-injection. The system includes a master control unit (MCU) that utilizes a firmware operated microprocessor. The MCU is connected to a plurality of sensors that sense critical system parameters that determine the engine settings. All system parameters are user-controlled by three system command switches that are located on a control display unit (CDU). The CDU is attached to the MCU by an electrical cable and is positioned on the vehicle to provide easy accessibility.
