    • Fuel oil clouding caused by formation of wax crystals in diesel fuel at low temperatures, which clouding restricts flow through and may plug the fuel filter of a diesel engine powered motor vehicle causing poor drivability, power loss and eventual flameout, is obviated by a fuel oil heater unit (10) which can readily convert a non-heated diesel engine spin-on type fuel filter (24) into one containing an electric heater for heating fuel above its cloud temperature. The heater unit (10) includes a spacer (22) insertable between the fuel manifold (12) and the filter (24) of the engine. The spacer (22) has a diameter comparable to that of the manifold (12) and filter (24) to present a flush overall outside surface and is provided with a star-shaped temperature self-limiting PTC heater (44) having radially extending finger-like portions (46) between each pair of which is provided a flow passage (26) through which the fuel flows and is heated enroute to the filter (24) from inlet (14) of the manifold. In an alternate arrangement a modified fuel manifold (12') is provided and includes an integralbowl-shaped recess (72) constituting a fuel reservoir in which is immersed a flat strip-like spirally coiled electric resistance heating element (78) connected in series with a combination thermostat/heating element (80) and defining a spiral heating passage for the fuel from manifold inlet (14') to the filter (24').
    • 在低温柴油燃料中形成蜡晶引起的燃料油混浊,这种混浊限制了流动,并且可能会堵塞柴油发动机动力汽车的燃油滤清器,从而导致驾驶性能差,功率损失和最终熄火,燃料油被消除 加热器单元(10),其可以容易地将未加热的柴油发动机旋转型燃料过滤器(24)转换成包含用于将燃料加热到其云温度以上的电加热器。 加热器单元(10)包括可插入燃料歧管(12)和发动机的过滤器(24)之间的间隔件(22)。 间隔件(22)具有与歧管(12)和过滤器(24)的直径相当的直径以呈现冲洗的整个外表面,并且设置有具有径向延伸的手指的星形温度自限制PTC加热器(44) 每一对之间设置有一个流动通道(26),燃料流过该通道,并从歧管的入口(14)被加热到过滤器(24)。 在替代方案中,提供了一种改进的燃料歧管(12'),并且包括构成燃料储存器的整体式弯曲形凹部(72),其中浸入与扁平状的螺旋卷绕的电阻加热元件(78)串联连接 组合恒温器/加热元件(80)并且限定用于燃料从歧管入口(14')到过滤器(24')的螺旋加热通道。
