摘要： A compression ignited, spark ignited, or surface ignited engine single or multi-cylinder low temperature starting system is positioned permanently or temporarily in the intake system during the engine starting and warming-up period for an extremely cold temperature engine condition. The low temperature starting system for these engine types is capable of starting on a wide variety of liquid fuels, E.G., high or low fuel volatility, high or low fuel boiling range and gaseous fuels. A pre-heat device which is fuel fired, electrically heated, chemically heated, heated by thermal storage or other means is used to pre-heat the air or air-fuel mixture. In any one of four different configurational modes, after an initial pre-heat period, air or an air-fuel mixture is drawn through a heat exchanger with an inlet restriction that acts to increase the air residency time in the heat exchanger which increases the temperature of the inducted air that in-turn reduces the opportunity for cold air to reach the combustion chamber and yields a rich air-fuel mixture in the combustion chamber. The heated rich air-fuel mixture in the combustion chamber is further heated by compression during the compression stroke to permit combustion to occur in a sustained manner prior to and after start-up. This invention allows engine startup at extremely low ambient temperatures. Cold cranking time and energy are substantially reduced due to the rapid build-up of heat in the combustion chamber.
摘要翻译：发动机起动和预热期间，对于极冷的发动机状态，压缩点火，火花点火或表面点火发动机单缸或多缸低温起动系统被永久地或临时地定位在进气系统中。这些发动机类型的低温启动系统能够从各种各样的液体燃料（例如，高燃料挥发性，低燃料沸点，低燃料沸点范围和气体燃料）开始。燃料燃烧，电加热，化学加热，通过热存储或其他方式加热的预热装置用于预热空气或空气 - 燃料混合物。在四种不同结构模式中的任一种中，在初始预热期之后，空气或空气 - 燃料混合物通过具有入口限制的热交换器被吸入，该入口限制用于增加热交换器中的空气驻留时间，这增加了温度导入的空气，这反过来又降低了冷空气到达燃烧室的机会，并在燃烧室中产生了丰富的空气 - 燃料混合物。在压缩冲程期间，通过压缩将燃烧室中的加热的富空燃混合物进一步加热，以在启动之前和之后持续地进行燃烧。本发明允许在极低的环境温度下启动发动机。由于燃烧室中的热量迅速积聚，冷启动时间和能量显着降低。

摘要： A lightweight back-pack generator set having a spark-ignited engine operating on middle distillate fuels (e.g., JP-5, JP-8 and F-34) has been provided. The generator set includes a back-pack frame; an alternator; and a spark-ignited combustion engine adapted to operate on a middle distillate fuel. The engine uses a preheater for heating the intake manifold to facilitate start-up operation of the engine. The present invention also provides a simple and inexpensive method for converting a spark-ignited gasoline engine to operate on a middle distillate fuel for providing a lightweight engine suitable for driving an alternator, a portable generator, or other portable equipment.
