一种汽车燃油效率改良装置 技术领域
本实用新型涉及一种汽车节油的装置，尤其涉及一种可用以协助汽车减少行进 间引擎室各皮带驱动系统的空转，及减少行进间因各类交通因素须较长时间暂停时 的怠速燃油消耗， 以达省油兼顾行车舒适的节能装置。 背景技术
近年来汽车产业迅速发展， 大幅缩短了交通所需的时间， 但燃烧汽油产生的二 氧化碳却导致温室效应， 破坏空气质量。 汽车引擎所燃烧的汽油， 大约只有 30%用 于产生能量推动汽车， 其余的能量皆转化成热量， 经由散热系统及废气系统浪费掉 了。 面对日益枯竭的石油能源与不断升温的地球暖化问题， 改善既有科技与使用习 惯， 以提升燃料效率即为大家共同的责任， 特别是还伴随着都市空气与噪音污染的 - 汽车产业。 据报导， 美国的石油使用量占全世界的 1 /4， 而其中 55%是用在两亿三 千多万辆的汽车上； 如果按这个比例计算， 全世界的石油使用量， 约有一半是做为 汽车燃料之用， 因此， 汽车对石油的依赖与对环境的破实在太大了。
然而， 即便各大汽车公司过去十年来竭尽全力来开发下世代汽车， 例如气电混 合车等等； 但至今传统的汽、 柴油动力引擎汽车仍占生产量的绝大部分 (估计约九 成以上）， 因此整体而言， 能源节约的成效非常有限。
传统汽、 柴油引擎汽车之所以耗油的原因之一， 是在于引擎怠速时仍在运转， 怠速的时间短者数秒， 长则数分钟， 甚至更长， 如果手动关闭引擎， 则须将排档切 换至空档（N档）或停驻档（P档）才能重新启动； 为了防止过度消耗电力导致电池剩 余电量不足， 车内的电器则必须同时关闭电源， 十分不便。 再如图 1所示， 现有的 汽车驱动装置， 是在引擎 1曲轴同轴地串设一第一主动传动轮 11与一第二主动传 动轮 12 ,第一主动传动轮 11藉由第一传动组件 32连接设在发电机系统 3的第一被 动传动轮 31 ;第二主动传动轮 12藉由第二传动组件 42连接设在空调系统 4的第二 被动传动轮 41。 驾驶者操作第一启动点火开关 9A时， 由电池 6供应电力至设在引 擎 1的引擎启动点火系统 1 3以启动引擎， 引擎运转时， 则同时带动第一主动传动 轮 1 1与第二主动传动轮 12 , 因此， 无论是否使用空调， 空调系统 4都必须被驱动 运转； 无论电池 6的蓄电量是否已满， 引擎 1也必定同时带动发电机系统 3来继续 产生电力对电池 6进行充电。 同样的， 即使车辆行进间须暂停， 引擎在怠速中也维 持运转， 使得引擎的负荷过重， 直接增加了油耗， 降低了燃油效率。 发明内容

本实用新型所述的汽车燃油效率改良装置中， 所述的主、 被动传动轮， 以及传 动组件， 可以采用一般汽车驱动机构中常用的皮带轮与皮带， 或是链轮与链 。

本实用新型所述的汽车燃油效率改良装置中，可进一步在驾驶座的前舱设置一 电性连接于前述控制电路的信息显示单元，让驾驶者从该信息显示单元清楚查看电 池的电量与各项耗电信息。
本实用新型所述的汽车燃油效率改良装置中，不直接将第一主动传动轮及第二 主动传动轮固定连接于引擎曲轴， 而是在引擎曲轴与第一主动传动轮的间设置第一 离合器， 以及在第一主动传动轮与第二主动传动轮的间设置第二离合器， 并提供一 控制电路来控制第一离合器与第二离合器适时动作 , 以控制第一主动传动轮及 /或 第二主动传动轮被驱动旋转。 另藉由侦测汽车电池储存的电量高于一设定值， 且不 使用空调系统时， 第一离合器与第二离合器均不动作， 让引擎在最轻的负荷状态下 运作。 当侦测到电池的电量低于一设定值， 但不使用空调系统时， 则控制第一离合 器将第一主动传动轮与引擎曲轴连结， 使引擎驱动发电机产生电力充入电池。 当电 池的电量高于一设定值， 且要使用空调系统时 则第一离合器不动作， 而控制第二 离合器动作将第一主动传动轮与第二主动传动轮连结，转换为由电池提供电力驱动 发电 转， 进而经由第一主动传动轮与第二主动传动轮驱动空调系统运转。 当侦 测到电池的电量低于一设定值， 且要使用空调系统时， 则控制第一离合器与第二离 合器同时动作， 藉由第一离合器将第一主动传动轮和曲轴连结， 且第二离合器动作 将第一主动传动轮与第二主动传动轮连结，使引擎运转时， 同时带动发电机产生电 力充入电池， 以及带动空调系统运转。

图 9 为本实用新型中的第二实施例的第一离合器连结引擎曲轴与第一主动传 动轮， 以及第二离合器连结第一主动传动轮与第二主动传动轮的示意图。 具体实施方式
以下配合说明书附图对本实用新型的实施方式做更详细的说明，以使本领域技 术人员在研读本说明书后能据以实施。
如图 2所示为本实用新型的第一实施例， 包括有一引擎 1、 一发电机系统 3、 一空调系统 4与一控制电路 5 ; 其中， 引擎 1连接至汽车的传动系统， 用来提供汽 车动力； 引擎 Γ还设有一引擎转速侦测系统 14。发电机系统 3设有一第一被动传动 轮 31 ; 空调系统 4设有一第二被动传动轮 41。 引擎 1的曲轴 10活动地连接一中心 轴， 该中心轴活动地串设有一第一主动传动轮 11与一第二主动传动轮 12， 该第一 主动传动轮 11利用第一传动组件 32连接设于发电机系统 3的第一被动传动轮 31 ; 第二主动传动轮 12利用第二传动组件 42连接设于空调系统 4的第二被动传动轮 41。第一主动传动轮 11与曲轴 10之间的中心轴活动地串设一第一离合器 2A; 第一 主动传动轮 1 1与第二主动传动轮 12之间的中心轴活动地串设一第二离合器 2B。在 本实用新型的实施例中， 所述第一主动传动轮 11、 第二主动传动轮 12、 第一被动 传动轮 31与第二被动传动轮 41可以采用目前十分普遍使用的皮带轮，且第一传动 组件 32与第二传动组件 42配合采用皮带。 第一主动传动轮 11、 第二主动传动轮 12、第一被动传动轮 31与第二被动传动轮 41也可以采用链轮，且第一传动组件 32 与第二传动组件 42配合釆用—链条。
所述控制电路 5电性连接第一离合器 2A、 第二离合器 2B、 发电机系统 3、 引 擎转速侦测系统 14与配备于汽车的电池 6。该控制电路 5在接收到一讯号时，可控 制第一离合器 2A与第二离合器 2B同时或不同时动作， 使引擎曲轴 10与第一主动 传动轮 11连结或分离，及 /或该第一主动传轮 11与第二主动传动轮 12连结或分离， 该控制电路 5还依前述讯号而决定是否由电池 6直接供应电力予发电机系统 3运转， 进而驱动空调系统 4。
在实际运作时， 控制电路 5会侦测电池 6储存的电量， 若电量高于一设定值且 不使用空调系统时， 控制电路 5不会驱使第一离合器 2A与第二离合器 2B动作（如 图 2所示）， 因此， 引擎 1运转时不会驱动发电机系统 3与空调系统 4 , 让引擎在最 轻的负荷状态下运作。
如图 3所示， 当控制电路 5侦测到电池 6的电量低于一设定值（第一设定值） 的讯号时， 即自动从电池 6提供电力驱动发电机系统 3运转， 并侦测到第一主动传 动轮 11的转速与引擎曲轴 10的转速接近或相同时， 驱使第一离合器 2A动作， 使 第一主动传动轮 1 1和曲轴 10连结， 并停止供应电力予发电机系统 3 , 此时即转由 引擎 1驱动发电机系统 3运转产生电力充入电池 6。 当控制电路 5侦测到电池 6的 电量高于另一设定值（第二设定值）的讯号时， 即自动驱使第一离合器 2A解除对第 一主动传动轮 11与曲轴 10的连结， 引擎 1不再驱动发电机系统 3运转， 改由电池 6供应电力予发电机系统 3; 如此反复地控制动作。
如图 4所示， 当控制电路 5侦测到电池 6的电量高于一设定值（第一设定值）， 且要使用空调时， 则第一离合器 2A不受控制电路 5驱使动作， 而控制电路 5驱使 第二离合器 2B动作将第一主动传动轮 11..与第二主动传动轮 12连结， 此时， 直接 由电池 6的电力驱动发电机系统 3运转， 进而经由第一主动传动轮 11与第二主动 传动轮 12驱动空调系统 4运转； 直到电池 6的电量不足时，控制电路对仍由电池 6 供电的发电机系统 3的转速加以调节， 使第一主动传动轮 1 1的转速与引擎曲轴 10 的转速接近或相同时， 再驱使第一离合器 2A动作将第一主动传动轮 1 1与曲轴 10 连结， 由引擎带动发电机系统 3产生电力充入电池 6 ; 如此反复地控制动作。 如图 5所示， 当控制电路 5已经侦测到电池 6的电量低于一设定值（第一设定 值）而正在驱使发电机系统 3运转以产生电力充入电池 6，电量尚未高于另一设定值 (第二设定值)且要使用空调时的状况， 控制电路 5驱使第一离合器 2A由原先的动 作改为不动作， 然后控制电路 5驱使第二离合器 2B动作， 控制电路要求电池 6供 电予发电机系统 3 , 同时对转速加以调节使第一主动传动轮 1 1 的转速与引擎曲轴 10的转速接近或相同时再驱使第一离合器 2A动作将第一主动传动轮 11与曲轴 10 连结，此手续可消除引擎运转时开启冷气空调且仍须发电时因系统间角速度不一致 导致的不顺畅。 之后控制电路 5驱使第一离合器 2A与第二离合器 2B同时动作， 藉 由第一离合器 2A将第一主动传动轮 11和曲轴 10连结，且第二离合器 2B动作将第 一主动传动轮 11与第二主动传动轮 12连结， 因此引擎 1运转时， 能同时带动发电 机系统 3产生电力充入电池 6， 以及带动空调系统 4运转； 直到电池 6的电量回复 到第二设定值以上时， 控制电路 5 自动驱使第一离合器 2A解除对第一主动传动轮 11与曲轴 10的连结， 改由电池 6提供电力驱动发电机系统 3及空调系统 4运转； 如此反复地控制动作。
图 6至图 9显示本实用新型的另一实施例，可以在图 2所示及前述的装置基础 上进一步包含均与控制电路 5电性连接的一档位侦测系统 7、 一增设的第二启动点 火开关 9B、 一原本配备于汽车的第一启动点火开关 9A、 一设于引擎 1的引擎启动 点火系统 13， 以及一信息显示单元 8。 驾驶者行车中因各种交通因素需要暂停时， 可将排档杆打入空档（N档）或停驻档（P档） , 此时档位侦测系统 7会侦测到车辆排 挡系统位于空档或停驻档， 并由控制电路 5开始计算时间， 到达一设定的时间时， 控制电路 5即对引擎起动点火系统 13执行熄火指令， 但仍供应车内配备的各项电 器设备所需的电力， 引擎即不再运转而节省燃料的消耗， 控制电路 5会监控电池 6 剩余电量， 当电池 6的电量低于一设定值（第一设定值） ， 控制电路 5会启动点火 系统 13将引擎 1重新启动。 需要继续行驶时， 如引擎仍处于熄火状态， 驾驶者必 须操作第一启动点火开关 9A或第二启动点火开关 9B才可由引擎起动点火系统 13 重新起动引擎。 所述增设的第二启动点火开关: 9B主要是为方便驾驶者操控， 因此. 可以设置在排挡杆的适当位置上， 便于在排档的同时按压操作。
所述信息显示单元 8可以配合显示器设置在汽车驾驶座的前舱，让驾驶者从信 息显示单元 8清楚查看电池的电量与各项耗电信息。所述信息显示单元 8可以显示 包括单位时间的耗电量， 发电机的充电量， 发电机停止供电时根据耗电量、 实时的 电池电量所推算的用电剩余时间等信息。 本实用新型的特点在于尽量减少压缩机与发电机系统对引擎的依赖，大幅降低 引擎的负荷， 以及减少引擎在怠速状态下所消耗的燃料， 达到整体减少燃料消耗而 提升燃油效率的目的。
以上所述仅为用以解释本实用新型的较佳实施例，并非企图据以对本实用新型 做任何形式上的限制 , 因此， 凡有在相同的创作精神下所作有关本实用新型的任何. 4爹饰或变更， 皆仍应包括在本实用新型意图保护的范畴。
