Abstract: One aspect of the present application relates to a polyphenylene ether resin composition including a modified polyphenylene ether compound (A) that is terminally modified with a substituent having a carbon-carbon unsaturated double bond, and a crosslinking-type curing agent (B) having two or more carbon-carbon unsaturated double bonds in each molecule, the modified polyphenylene ether compound (A) including a modified polyphenylene ether compound (A-1) having a specific structure, and a modified polyphenylene ether compound (A-2) having a specific structure.

Abstract: A starting system of an engine according to the present invention comprises an electromagnetically-operated fuel resupply pump for supplying auxiliary fuel to an intake passage of the engine, and various detectors for detecting the operating conditions of the engine, e.g., engine speed, temperature of engine cooling water, drive of a starting motor, etc., and a control circuit for controlling the drive of the fuel resupply pump in accordance with signals from the detectors. The control circuit is partially formed of a microcomputer, which controls the pump so that a pulse voltage is applied to a solenoid of the pump for a longer time when the engine is in a cranking state than when the engine is in any other operating state.

Abstract: A warming-up system of an engine for an automobile according to the present invention is provided with main and auxiliary nozzles in an air intake passage of a carburetor. The auxiliary nozzle is connected to an electromagnetically-operated fuel resupply pump. The warming-up system is further provided with a position detector for determining whether or not a throttle valve is in an open position, a rotation detector for detecting the rotational frequency of the engine, and a control circuit for controlling the drive of the pump in accordance with signals from the detectors. Based on the rotational frequency of the engine detected by the rotation detector, the control circuit determines whether the engine is in a cranking state or in a complete detonation state. When the engine is in the complete detonation state, the control circuit drives the pump to supply a predetermined quantity of auxiliary fuel to the intake passage through the auxiliary nozzle.
