Title: Preparation of coal/water slurry
Inventor: IGARASHI TAIZOU
IPC: C10L1/32
Filed: 1982-07-24
Abstract: PURPOSE:To obtain a low-viscosity coal/water slurry with addition of a small amt. of water by milling coal in water by fractionally adding the dispersant at intervals during milling of the coal. CONSTITUTION:In a method of preparing coal/water slurry by milling coal in water, a dispersant is fractionally added to the mill at intervals.

Title: Method of controlling air-fuel ratio of internal combustion engine
Inventor: TAKIMOTO TOSHIYUKI
IPC: F02D41/00
Filed: 1984-06-22
Abstract: PURPOSE:To prevent the air-fuel ratio from being enriched when the control of increment of fuel is carried out instead of the feed-back control of air-fuel ratio, by carrying out the feed-back control of air fuel ratio for every predetermined time to learn deviations in air-fuel ratio due to variations in the density of intake-air. CONSTITUTION:During operation of an engine, an electronic control circuit 8 determines whether the demand which requires the control of increment of fuel is present or not in accordance with the turn-on or turn-off of a power switch 12, and if the demand is not present, feed-back control is carried out such that the amount of fuel injection from a fuel injection valve 2 is compensated in accordance with the output of an O2 sensor 4. On the contrary, if the demand is present, the control of increment of fuel is carried out while the above-mentioned feed-back control is creased. In this stage, when the control of increment of fuel is continued for a predetermined time, it is interrupted for a predetermined time while the feed-back control of air-fuel ratio is carried out. Further, the deviation between an actual air-fuel ratio during control of fuel increment and a stoichiometric air-fuel ratio is leanred, and is used for compensating the actual air-fuel ratio during control of fuel increment which is carried out thereafter.

Title: Control system for direct-injection engine
Inventor: IZUMIURA ATSUSHI
IPC: F02D41/04
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To control the air-fuel ratio of an engine in consideration of changes in engine load resulting from changes in viscosity of its automatic transmission fluid. SOLUTION: The engine control system for a vehicle mounted with an automatic transmission 40 has a target air-fuel ratio decision means 33 for deciding a target engine air-fuel ratio depending on engine operating parameters, and a correction means 34 for correcting the target air-fuel ratio depending on the temperature of automatic transmission fluid(ATF) in the automatic transmission 40. An ATF temperature of or below a preset value prohibits an engine operation at a lean air-fuel ratio mode. The correction of the target air-fuel ratio according to the ATF temperature permits this air-fuel ratio control to reflect changes in engine load caused by changes in ATF viscosity, and resolves the state wherein the ATF viscosity disables the engine from outputting a desired driving force.
