Abstract: There are provided a resin composition that is suitable for the production of a flame-retardant molded article and that can provide high flame retardancy even with a small amount of flame retardant added, and a flame retardancy determination method for determining the flame retardancy of a resin composition. The resin composition of the present invention contains a thermoplastic resin, a cellulosic material, and a phosphate flame retardant and satisfies relational expressions (1) and (2) (where in expressions (1) and (2), TP, TB, and TCMP are temperatures at weight loss rate peaks in thermogravimetric analysis, TP is a temperature (° C.) at a weight loss rate peak of the thermoplastic resin, TB is a temperature (° C.) at a weight loss rate peak of the cellulosic material, and TCMP is a temperature (° C.) at a weight loss rate peak of the resin composition. When the resin composition has two weight loss rate peaks, TCMP is a temperature at a peak on a lower temperature side).

Abstract: A fuel supply control system for internal combustion engines with an air flow mounted in a intake manifold, a throttle valve opening sensor and a control unit, in which at quick acceleration the control unit generates a correction air flow quantity signal in accordance with the change of the output of the throttle valve opening sensor and corrects the output signal of the air flow sensor by the correction air flow quantity signal, whereby estimating real air flow quantity sucked into the engine cylinders.

Abstract: To improve the operating efficiency of a diesel engine, a plurality of engine operating parameters are detected and the engine cylinders to which the fuel supply is to be cut off are computed in accordance with the operating parameters, thereby stopping the generation of fuel control pulses in response to crank angle sensor output pulses indicative of the computed cylinders. A fuel injection pump is so constructed that the fuel is metered in response to the fuel control pulses and the metered fuel is pressurized, compressed and distributed to the cylinders, and the distribution of the pressurized and compressed fuel to the cylinders is stopped by stopping the application of the fuel control pulses.

Abstract: A method and a system are disclosed for controlling the amount and advance of fuel injection of a diesel engine using an injection pump of the type which defines the fuel supply period and the compression period, alternately, in synchronism with explosion-exhaustion and intake-compression strokes of each cylinder of the engine, and includes first and second pressure chambers to be supplied with fuel through first and second electromagnetic valves, respectively, during the fuel supply period, and the fuel in the amount equivalent to the fuel amount supplied to said second pressure chamber being injected into the cylinder at an injection timing determined from the total amount of the fuel supplied to said first and second pressure chambers. The open time intervals of the first and second electromagnetic valves are determined from the fuel amount to be injected into each cylinder and the injection timing advance which are determined in accordance with the engine operating conditions.
