摘要： A method for economically manufacturing an iron-boron-silicon alloy through simple steps, which comprises the steps of: adding a boron raw material and a carbonaceous reducing agent to a molten iron received in a vessel; blowing oxygen gas into the molten iron to reduce the boron raw material in the molten iron by means of the carbonaceous reducing agent to prepare a boron-containing molten iron; continuing the blowing of oxygen gas to decarburize the boron-containing molten iron until the carbon content in the boron-containing molten iron decreases to up to 0.2 wt. %; and adding at least one of silicon and ferrosilicon to the boron-containing molten iron while stirring the boron-containing molten iron, thereby manufacturing an iron-boron-silicon alloy.

摘要： A lean burn internal combustion engine has a basic fuel injection amount calculated and multiplied by a lean correction factor, the resulting amount controls the air fuel ratio of the engine. The lean correction multiplied by factor is calculated from a first map based on intake pressure and engine speed. However, when the degree of opening of the throttle valve is larger than a predetermined value, a second correction map based on the degree of opening of the throttle valve and engine speed is used to obtain the lean correction factor. When the second correction map is employed, an ignition timing map based on the degree of opening of the throttle valve and engine speed is used to obtain an ignition timing; instead of the usual ignition timing, based on intake pressure and engine speed.

摘要： An air-fuel ratio control device for an engine, by which the air-fuel ratio of the air-fuel mixture supplied to the engine is changed. The device set the air-fuel ratio to a lean mixture when the engine load is lower than a set load value and predetermined set speed, and when the engine load become higher than the set load value, or the engine speed exceeds the set speed, the device switches the air-fuel ratio from a lean mixture to a rich mixture to obtain higher engine output. The set load value is varied in accordance with the engine speed such that it is reduced as the engine speed is increased.

摘要： A traction control device comprising a fuel supply control device for controlling the supply of fuel fed into the engine cylinders. When the temperature of the engine is high, if the speed difference between the rotating speed of the free running wheel and the rotating speed of the driven wheel exceeds a predetermined value, the supply of fuel fed into some of the cylinders or all of the cylinders is stopped. Conversely, when the temperature of the engine is low, even if the speed difference exceeds the predetermined value, the feeding of fuel to all of the cylinders is continued.

摘要： When an ECU determines that an accelerator is “ON” and a brake is “ON”, the ECU determines whether or not the brake previously depressed is “OFF”. When the ECU determines that the brake previously depressed is “OFF” and that the vehicle is in the reduced speed state, the vehicle control apparatus is configured to execute an engine output reduction control process under the condition that the simultaneous depressions of the accelerator and brake pedals continues for less than 10 seconds and the vehicle speed is not less than 7 km/hr. When the simultaneous depressions of the accelerator and brake pedals continues for no less than 10 seconds, the ECU is configured to make an output reduction prohibition flag “ON” and not to execute the engine output reduction control process until a predetermined time elapses.

摘要： Disclosed is a vehicle control apparatus which can prevent a drivability of a vehicle from being deteriorated. When an ECU determines that an accelerator is “ON” and a brake is “ON”, the ECU determines whether or not the brake previously depressed is “OFF”. When the ECU determines that the brake previously depressed is “OFF” and that the vehicle is in the reduced speed state, the vehicle control apparatus is operative to execute an engine output reduction control process under the condition that the simultaneous depressions of the accelerator and brake pedals continues for less than 10 seconds and the vehicle speed is not less than 7 km/hr. When the simultaneous depressions of the accelerator and brake pedals continues for no less than 10 seconds, the ECU is operative to make an output reduction prohibition flag “ON” and not to execute the engine output reduction control process until a predetermined time elapses.

摘要： An apparatus for controlling an air-fuel ratio in a lean burn internal combustion engine, such that three different air-fuel ratio zones are set, the three zones being an ultra lean zone with a low load, a medium lean zone with a medium load, and a non-lean zone with a high load. When the engine is under low load conditions, a map FLEANPM is selected to obtain an ultra lean air-fuel ratio based on detected intake pressure PM values and engine speed NE. When the engine is under medium load conditions, a map FLEANTA is selected to obtain a medium lean air-fuel ratio based on a detected throttle opening values TA and engine speed NE. When the engine is under high load, conditions the lean correction control is canceled, thereby obtaining a theoretical air-fuel ratio or an air-fuel ratio smaller than the theoretical air-fuel ratio, and when the engine remains at a point in the medium lean zone, the air-fuel ratio decreases gradually toward the theoretical air-fuel ratio as time elapses.
