Abstract: In a fuel control system of an engine having an air conditioner driven by the engine, fuel supply is cut during deceleration of the engine when the engine speed is higher than a first preset value with the air conditioner on and when the engine speed is higher than a second preset value with the air conditioner off, the first preset value being higher than the second preset value. When the air conditioner is turned off during the deceleration of the engine, fuel supply is cut when the engine speed is higher than the first preset value, and when the air conditioner is turned on during the deceleration of the engine, fuel supply is cut when the engine speed is higher than the second preset value.

Abstract: A control system for a vehicle, including an automatic transmission provided with a multiple transmission gear mechanism, automatically establishes a specific gear stage of a speed ratio from among a plurality of gear stages in accordance with an vehicle operatiing condition. A shift control signal producing device produces a shift control signal in order to produce a shift operation between different gear stages in accordance with the vehicle operating condition. An engine output control device reduces an engine output in synchronism with the shift operation so as to suppress a torque shock due to the shift operation. A detecting device detects a specific vehicle operating condition in which a change in a time lag between a generation of the shift control signal and an actual initiation of the shift operation in the transmission is greater than a predetermined level and produces a signal denoting the specific vehicle operating condition.

Abstract: A gear-shifting shock suppressing system for a vehicle provided with an automatic transmission which shifted to a desired gear-speed on the basis of a gear-shifting signal controls the output of the engine of the vehicle in order to suppress gear-shifting shock which occurs when the automatic transmission shifts. The gear-shifting shock suppressing system detects the interval between successive two gear-shifting signals and controls the output of the engine when the interval between successive two gear-shifting signals is longer than the predetermined time in a manner different from the manner in which the gear-shifting shock suppressing system controls the output of the engine when the interval between successive two gear-shifting signals is shorter than the predetermined time.

Abstract: An air-to-fuel ratio control system executes a feedback control of air-to-fuel ratio based on an output of an oxygen sensor.

Abstract: A heavy hydrocarbon feed stock is, after being heat-treated in a first cracking zone, introduced into a second thermal cracking zone for obtaining a thermally cracked product and a pitch product. The second cracking zone has a plurality of cracking reactors which are connected in series, through which is successively passed the treated feed stock and to each of which is supplied a gaseous heat transfer medium to maintain the liquid phase therein at a temperature sufficient for effecting the thermal cracking and to strip the resulting distillable, cracked components from the liquid phase. The thermal cracking temperature in one reactor is so controlled as to become higher than that in its adjacent upstream-side reactor. The distillable, cracked components in respective reactors are removed overhead therefrom and separated into a heavy fraction and a light fraction, while the liquid phase in the downstream-end reactor is discharged therefrom for recovery as the pitch product.
