摘要： PROBLEM TO BE SOLVED: To provide a failure diagnosing device capable of surely determining the micro leakage, and the abnormality caused by the micro leakage in a system for preventing transpiration of evaporated fuel.
SOLUTION: In a case when a first pressure recovery amount (ΔP) measured after depressurizing a failure diagnosis area, is over a first or second determination value (L11, L12), a second pressure recovery amount (reΔP) is measured after the failure diagnosis area is opened to the atmospheric air, and then sealed. The second pressure recovery amount is compared with a third determination value (L21), when the first pressure recovery amount is between the first determination value and the second determination value, on the other hand, when the first pressure recovery amount is over the second determination value, the second pressure recovery amount is compared with a fourth determination value (L22). When the first pressure recovery amount is over the first determination value, and the second pressure recovery amount is not over the third determination value, or when the first pressure recovery amount is over the second determination value, and the second pressure recovering amount is not over the fourth determination value, the leakage is determined.

摘要： PROBLEM TO BE SOLVED: To provide a failure determining device for a water temperature sensor which positively determines a failure of the water temperature sensor irrespective of an operating situation.
SOLUTION: It is determined whether an internal combustion engine at warming up is in an operating state of affecting a cooling water temperature WT on the basis of a calorific value estimated from a suction air capacity detected by an air flow sensor. Clocking by a timer is started from a point of time when it is determined that the internal combustion engine is in the operating state of affecting the cooling water temperature. The clocking by the timer is carried out under a condition that it is determined that the internal combustion engine is in the operating state of affecting the cooling water temperature after starting clocking. It is judged that there is a failure when a sensor detected value does not fluctuate out of a set water temperature range throughout a predetermined time (300 sec) even though it is determined that the internal combustion engine is in the operating state of affecting the cooling water temperature. Since determination is carried out by the timer in consideration of the calorific value fluctuating in response to an operating state of the internal combustion chamber, easy and accurate failure determination is enabled.

摘要翻译：要解决的问题：提供一种用于水温传感器的故障确定装置，其可以肯定地确定水温传感器的故障，而不管操作情况如何。解决方案：根据由空气流量传感器检测到的吸入空气容量估计的发热量，确定预热的内燃机是否处于影响冷却水温度WT的运行状态。从确定内燃机处于影响冷却水温度的运行状态的时刻起，通过定时器进行计时。在确定内燃机处于开始计时后影响冷却水温度的运行状态的条件下，通过定时器进行计时。即使确定内燃机处于影响冷却的运行状态，传感器检测值在规定时间（300秒）内不会在设定水温范围内波动的判定为失败水温。由于考虑到响应于内燃机的运行状态而变动的发热量，由定时器进行判定，因此能够进行容易且准确的故障判定。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine, for providing good startability, by appropriately controlling an air-fuel ratio in start of an engine, even if fuel biased to a property not susceptible to vaporization caused by vaporization of fuel along with increase in temperature of a fuel tank is supplied to the internal combustion engine.

摘要： PROBLEM TO BE SOLVED: To correctly judge the presence or absence of a slight or trace amount of leak in an evaporative emission control system for an evaporative fuel without being affected by change in atmospheric pressure. SOLUTION: If a 1st restored pressure (ΔP) measured after evacuation of a failure-diagnosis object domain exceeds a 1st or 2nd judgement value (L11, L12), a 2nd restored pressure (second ΔP1) is measured in a closed state after release of the failure-diagnosis object domain to atmospheric pressure. Then, the 2nd restored pressure is compared with a 3rd judgement value (L21) or a 4th judgement value (L22) depending on a relationship small or big between the 1st restored value and the 2nd judgement value. If the 1st restored pressure exceeds the 1st judgement value, and the 2nd restored pressure does not exceed a 3rd judgement value, or if the 1st restored pressure exceeds the 2nd judgement value, and the 2nd restored pressure does not exceed a 4th judgement value, then the presence of leak is judged. If atmospheric pressure (BP) drops at least in a specified value during the measurement of the 1st restored pressure, then the 4th judgement value is replaced by the 3rd judgement value.

摘要： PROBLEM TO BE SOLVED: To provide a thermostat failure diagnostic device for internal combus tion engines that can efficiently diagnose failures in thermostats, while preventing errors in diagnosis. SOLUTION: After the start-up of an engine 1, the thermostat failure diagnostic device detects failures in a thermostat 22 from the time the cooling water temperature upstream of the thermostat 22 takes to rise by a preset degree or to a preset temperature, as long as a parameter value correlating with the intake air amount or fuel injection quantity of the engine 1 remains not less than a preset value and the cooling water temperature in general is practically equal to the intake air or outside air temperature. A thermostat failure diagnosis is thus performed, for appreciable reasonableness, not under small engine- generation heat quantity or high cooling water temperature conditions, when errors in diagnosis are liable to occur, but under relatively large engine- generating heat quantity conditions, which are immune to the errors in diagnosis.

摘要： PURPOSE: To surely diagnose the fault of PCV provided at a fuel evaporation gas suppressor, clogging of a pipe, etc. CONSTITUTION: An ECU 50 stores the average value I of the integration term of air-fuel feedback control, the revolution of an engine, etc., in the first place, and then, introduces purge air by opening PCV 46. And, after introduction of purge air, it stores the average value I of the integration term, the revolution of an engine, etc., again, and in case that a change is scarcely detected in the values before and after the introduction of purge air in each, this judges that PCV 46 is faulty. And, in time of introduction of purge air, until the amount of introduction reaches the specified value, the amount of introduction is increased at a relatively small rate of increase ΔDPR, and after it reaches the specified value, the amount of introduction is increased at a relatively large rate of increase ΔDLA.
