摘要： A requested injection amount of fuel necessary during ignition cut-off at the time of start at an extremely low temperature is calculated (step ST2), injection start timing and injection end timing between which wetting of a spark plug by fuel is less likely are set (step ST3), and the number of times of ignition cut-off is calculated based on the injection start timing and the injection end timing and the requested injection amount (step ST4). The injection start timing and the injection end timing are thus restricted to timings between which plug wetting is less likely, and the number of times of ignition cut-off is calculated based on the injection start timing and the injection end timing and the requested injection amount, so that wetting of the spark plug by fuel at the extremely low temperature can be avoided even in an in-cylinder direct-injection engine.
摘要翻译：计算在极低温度下起动时的点火切断期间所需要的燃料喷射量（步骤ST2），喷射开始时刻和喷射结束时刻之间不太可能用燃料对火花塞进行润湿（步骤ST3），并且基于喷射开始正时和喷射结束定时以及所请求的喷射量计算点火切断次数（步骤ST4）。因此，喷射开始时刻和喷射结束定时被限制在不太可能的插头润湿之间的定时，并且基于喷射开始正时和喷射结束时刻以及所请求的喷射量计算点火切断次数，因此即使在缸内直喷式发动机中也能够避免火花塞在极低温度下的燃料润湿。

摘要： A fuel-injected engine is operated in a compression stroke injection mode or an intake stroke injection mode. The intake flow rate appropriate for the compression stroke injection mode is greater than that of the intake stroke injection mode. When the engine is cold, the ECU determines the amount of fuel injected in accordance with the actual intake flow rate. The ECU controls a throttle valve such that the intake flow rate is appropriate for the selected fuel injection mode before the fuel injection mode is actually switched. As a result, fluctuations of the engine speed caused by switching the fuel injection mode are reduced.

摘要： An engine has an injector, which directly injects fuel into a combustion chamber. When the coolant temperature during the cranking of the engine is low, an ECU controls the injector such that the engine is operated in a compression stroke injection mode. When the engine is operated in the compression stroke injection mode, the ECU controls the injector to advance the fuel injection timing in accordance with an increase of the coolant temperature. As a result, the engine reduces the amount of unburned discharge gas, provides improved ignition and combustion, and provides stable idling.

摘要： A concrete filled steel tube column. The concrete filled steel tube column includes a steel tube having an inner face; a concrete core disposed within the steel tube; and a separating layer interposed between the inner face of the steel tube and the concrete core for separating the concrete core from the inner face of the steel tube so that the steel tube may not be bonded to the concrete core. After the separating layer is formed on the inner face of the steel tube, the concrete is charged into the steel tube to form a concrete core.

摘要： A DPD tracking error signal detection apparatus includes the following. Four differentiators remove DC components and differentiate four signal with varying differential phases. The signals are then sampled and quantized by four A/D converters, and output to a non-inverting unit and an inverting unit. A phase inverter/compositor then leaves as-is or phase-inverts the output signals, according to a control signal. The non-inverting and the inverting unit each include two Hilbert transformers that phase-shift the output from the A/D converters, two delay units that delay the output of the other A/D converters to match the delay of the Hilbert transformers, two cross-correlators that calculate the cross-correlation between pairs of Hilbert transformers and delay units, and an adding unit that combines the cross-correlator results and outputs the combined result to the phase inverter/compositor.

摘要： The system of the invention includes a circuit breaker switching control section (100) and a setting control section (700) connected therewith through a communication network (500). The circuit breaker switching control section (100) transmits a circuit breaker state quantity acquired by a signal input section (120) through the communication network to a set value calculation section (740) of the setting control section (700). The set value calculation section (740) of the setting control section calculates a set value to be set in the switching control section (100) of the circuit breaker, using the state quantity of the circuit breaker that was transmitted thereto. The setting control section (700) transmits to the circuit breaker switching control section the set value calculated by the set value calculation section (730) through the communication network. A switching control calculation processing section (140) provided in the switching control section of the circuit breaker corrects the circuit breaker switching actuation time in accordance with this set value and calculates a delay time in respect of the zero-cross point in accordance with this corrected switching actuation time and power system period.

摘要： A valve characteristic control apparatus is provided in an internal combustion engine including a variable valve mechanism that can change at the least, among valve characteristics of an exhaust valve, a closing timing of the exhaust valve, and in which a number of injections of fuel is changed during one engine cycle. The valve characteristic control apparatus sets the closing timing of the exhaust valve to a retard side during an engine warming up operation. When setting to the retard side is performed, if two injections are performed, an exhaust side target displacement angle VTTex of the exhaust valve is calculated based on a dual injection use map. On the other hand, if one injection is performed, the exhaust side target displacement angle VTTex of the exhaust valve is calculated based on a single injection use map.
