摘要： A control system employs a microcomputer, which controls the starting operation of a spark ignition type engine provided with a fuel injection system. The control system is loaded with, at least, contact information of an ignition switch for connecting an ignition device to a power supply and a starter switch for connecting a starter motor to the power supply, and an output signal of a temperature sensor for detecting the temperature of cooling water of the engine. Where the cooling water temperature is not higher than a predetermined temperature, a fuel pump which supplies pressurized fuel to an injector of the fuel injection system is started simultaneously with the closure of the ignition switch, and this fuel pump is stopped during the operation of the starter motor.

摘要： PROBLEM TO BE SOLVED: To improve sealed properties even when supply fuel pressure is high such as an inter-cylinder direct fuel injection method, by respectively connecting the upper and lower ends of a cylindrical ring to a core and a yoke in a condition that the remaining compressed stress is maintained which is larger than the remaining stress generated when connecting. SOLUTION: A core 1 is inserted in a yoke 2, and the core 1 and the yoke 2 are mutually connected in the upper end part of the yoke 2. A coil bobbin 13 is inserted in a space between the core 1 and the yoke 2. A coil 10 is retained in this space. Also, a ring 9 is fixed between the core 1 and the yoke 2, and the material of the ring 9 is a SUS material harder in comparison with the core 1 and the yoke 2. The upper end part of the ring 9 and the lower end part of the ring 9 are respectively bitten into the lower end surface of the core 1 and the inside lower part of the yoke 2. The core 1 and the yoke 2 are connected to each other after the core 1 is previously pressurized, therefore the remaining compressed stress is generated in the upper and lower end parts of the ring 9, and sealed properties can be improved.

摘要： PURPOSE:To activate an adsorbent and improve the adsorption performance by connecting a conduit means guiding the hot air around an exhaust pipe to the air inlet of a canister in a control device having the canister absorbing the adsorbed evaporation fuel into an engine. CONSTITUTION:An adsorbent 2 is filled in the canister main body 1 of a canister 3, the top section of the canister main body 1 is connected to a fuel tank 5 via a fuel pipe 4 and to an intake tube 8 via an intake pipe 6 respectively. An air inlet 11 is provided at the bottom section of the canister main body 1. In this case, a guide pipe 13 with a gas escape hole 12 is connected around the air inlet 11, a flexible hot air purge hose 15 with one end 15A opened on the periphery of an exhaust pipe 14 is connected to the guide pipe 13. When the evaporation fuel adsorbed to the canister 3 is absorbed to an engine 7, the hot air around the exhaust pipe 14 is guided into the canister 3 to activate the adsorbent 2, and the working capacity of the canister 3 is improved.
