摘要： A compressed natural gas-fueled automotive vehicle is disclosed in which the fail-safe control operation is performed thereby to secure the safety of the vehicle when the gas pressure drops. If the remaining amount of the gas is very small, an engine misfire occurs. If the catalyst temperature is high, the uncombusted gas begins to burn on contact with the high-temperature catalyst in the catalyst unit. In view of this, upon detection of both a gas pressure drop and the vehicle moving condition or upon detection of both a gas pressure drop and an increased catalyst temperature, the fuel supply is stopped or the vehicle speed is reduced to thereby reduce the catalyst temperature. As a result, uncombusted gas is not burnt in the catalyst unit and the catalyst unit is prevented from being destroyed.
摘要翻译：公开了一种压缩天然气燃料汽车，其中执行故障保护控制操作，从而当气体压力下降时确保车辆的安全。如果气体的剩余量非常小，则发生发动机失火。如果催化剂温度高，则未燃烧的气体在与催化剂单元中的高温催化剂接触时开始燃烧。鉴于此，当检测到气体压降和车辆移动状况时，或者在检测到气体压降和增加的催化剂温度两者时，停止燃料供应或降低车辆速度，从而降低催化剂温度。结果，未燃烧的气体不会在催化剂单元中燃烧，并且防止催化剂单元被破坏。

摘要： A method and apparatus is provided that can detect even small amounts of gas leakage and can perform a proper fail-safe operation when gas leakage is detected. When an engine is stopped and a gas shut-off valve is closed, the amount of decrease of gas pressure is calculated by comparing initial gas pressure with the gas pressure detected after the elapse of a prescribed time, to detect gas leakage. In one embodiment, gas leakage is detected by calculating the accumulated value of the amount of decrease of gas pressure each time the engine is stopped. In another embodiment, gas leakage is detected by calculating the rate of decrease of gas pressure from the initial gas pressure to the gas pressure detected after the elapse of a prescribed time. In a further embodiment, gas leakage is detected by calculating the accumulated value of the rate of decrease of gas pressure each time the engine is stopped. Further, when gas leakage is detected, the gas shut-off valve is closed and a warning is issued.

摘要： The valve drive apparatus of the invention comprises an exhaust valve drive mechanism capable of changing an open/close timing of an exhaust valve, and a control device which controls the exhaust valve drive apparatus so as to release the exhaust valve during an intake stroke, independently of an exhaust stroke, in an EGR mode. Preferably, the exhaust valve drive mechanism comprises a first exhaust cam which defines the exhaust valve releasing timing and the amount of valve lift in the exhaust stroke, and a second exhaust cam which defines the exhaust valve releasing timing and the amount of valve lift during the intake stroke. In an normal mode, the displacement of the first exhaust cam is transmitted to the exhaust valve, and in the EGR mode, the displacement of the second exhaust cam is transmitted to the exhaust valve, in addition to the displacement of the first exhaust cam.

摘要： A variable valve mechanism has a switching mechanism for transmitting cam displacement to a first rocker arm from a second rocker arm. A camshaft is disposed obliquely above a rocker shaft. A first abutting portion and a second abutting portion are disposed in a dead space between an upper side of the rocker shaft and a side of the camshaft. The first abutting portion rotationally displaces in a rotational direction of rocker arms together with the first rocker arm. The second abutting portion rotationally displaces together with the second locker arm. The second abutting portion abuts on the first abutting portion from a rotating direction of rocker arms. In the switching mechanism thus configured, displacement of the second rocker arm is transmitted to the first rocker arm with reduced stress burden.
