Title: Fuel supply device of multi-cylinder internal combustion engine
Inventor: YONEKAWA MASAO
IPC: F02M55/02
Filed: 1989-01-11
Abstract: PURPOSE:To keep good restarting characteristic at high temp. by changing the fuel stagnation capacity of a holder part for supplying fuel depending upon the air temp. and maintaining fuel supply by the use of residual high-boiling point component (liquid) of the fuel. CONSTITUTION:After an engine 10 is restarted, fuel in a fuel tank 13 is fed, and at the inlet side 3 cylinder, the holder parts of injection valves 17a-17c are soon filled with cool fuel. If all six cylinders have small fuel stagnation capacity the residual liquid will flow off, which should cause stall or rough idling. On the other hand, the injection valves 17d-17f of the outlet side 3 cylinder have large fuel stagnation capacity, so that is takes long time for the residual liquid of the fuel in the holder parts to all becomes new fuel, and supply to the engine 10 can be made while residual liquid is stagnating. Thereafter the residual liquid in the outlet 3 cylinder 3 is consumed off, so that vapor will be generated. If all six cylinder have large fuel stagnation capacity, stall, etc., will be generated after the residual liquid is consumed off, but the injection valves 17a-17c sink sufficiently below the vapor generating temp., so that there is no problem with fuel supply.

A connection information storage device 3 stores connection information of Kana characters of the single syllable. An operating device 4 attains priorities of partial Kana character strings in accordance with Kana character strings in the device 2 and connection information by operation and selects, for example, 5 Kana character strings having higher priorities and stores selected them in a storage device 5. Five Kana character strings having higher priorities are selected though 5<2> two- syllable partial Kana character strings are generated, and selected them and the likelihood of the third single syllable are operated in 5<2> operations, and this operation is repeated to select the Kana charater string having a higher priority. Thus, the trouble of the Kana-Kanji conversion operation is reduced to make the operation easy.

Abstract: PURPOSE:To provide a combustion furnace which is free from deposition of a scale on the inner wall surface of a furnace body and enables continuous combustion operation, by providing a feed port for secondary air for main combustion, a main fuel injection nozzle for forming a main flame, and a feed port for tertiary air for main fuel combustion. CONSTITUTION:Main fuel F, injected through a main fuel injection nozzle 8 toward as assist combustion flame, is burnt by means of secondary air A2 fed from the inner peripheral part thereof and tertiary air A3 fed from the outer peripheral part thereof to form a vertical down main flame at the central part of the interior of a furnace body 1. In this case, since the tertiary air A3 is fed from the peripheral part of the main fuel F toward the main flame, a combustion product is prevented from making direct contact with the inner wall surfaces of a furnace top part 1a and a furnace side wall part 1b. Even when fuel containing an ash content is used as the main fuel F, the ash content forms scales which are adhered on the inner wall surfaces of the furnace top part 1a and the furnace side wall part 1b, and is prevented from growing. This constitution enables execution of long-term continuous operation.
