摘要： Braking systems for use with internal combustion engine have in the past used a variety of mechanical mechanisms to activate the braking system in addition to the conventional cam, lifters, pushrods and rocker arms. Many of these systems fail to provide the option of controllably and modulatively varying the sequence and amount of the opening and closing of an intake or exhaust valve relative to a piston position in a cylinder bore. The present invention provides an electronic control system outputting an discrete control signal, an opening device for unit actuation of each of the pair of valves independently. The electronic control system is programmable to respond in a first predetermined logic pattern for conventional operation of the engine at which time each of the pair of valves are in the closed position during the compression stroke. The electronic control system is programmable to a second predetermined logic pattern to vary the operation of the valves associated with the respective bore in the generally open position during the compression stroke when the piston in near the top dead center position. The preestablished logic pattern controllably, sequentially and modulateably actuate the device for unit actuation, moving each of the valves independently between the open and closed position to effectively resist the movement of a piston from a bottom dead center position to a top dead center position.

摘要： An annoying problem with diesel engines is combustion noise especially under high speed, low load conditions. The problem is caused by the relatively long ignition delay period or the period of time from the start of fuel injection into the combustion chamber until ignition occurs. The length of the ignition delay period influences the severity of the noise produced as it determines the amount of fuel that is ready to be burned. The length of the ignition delay period is strongly dependent on cylinder gas temperature during the initial part of the fuel injection schedule. The present invention provides an apparatus to reduce the ignition delay period by elevating the temperature of the air in a selected one of the combustion chambers so that at the start of the compression stroke the air is elevated reducing the ignition delay period.

摘要翻译： 柴油发动机的一个令人讨厌的问题是燃烧噪声，特别是在高速，低负载条件下。 该问题是由较长的点火延迟期或从燃料喷射开始到燃烧室直到发生点火的时间段引起的。 点火延迟时间的长短会影响产生的噪音的严重程度，因为它决定了准备燃烧的燃料量。 点火延迟时间的长短很大程度上取决于在燃料喷射计划的初始部分期间的气缸温度。 本发明提供了一种通过提高所选择的一个燃烧室中的空气的温度来减少点火延迟时间的装置，使得在压缩冲程开始时，空气升高，从而降低点火延迟时间。
