摘要： The noise level of a V-type diesel engine is reduced by providing a multi-piece intake manifold system including a pair of separate intake manifolds mounted on the inside valley defining walls of the engine cylinder banks and joined by an air supplying manifold connector mounted on both manifolds with isolation mounting means that limit the transmission of noise creating vibrations to the connector and between the manifolds and their respective cylinder banks.

摘要： An oil cooled diesel engine piston is designed to restrict heat loss from the combustion chamber through provision of a combustion chamber insert defining a central non-oil-cooled chamber and a surrounding annular insulating air gap. The air gap controls heat flow primarily between the combustion gas exposed wall of the insert and an adjacent coolant exposed wall of the main piston volume.The insert is press fitted into a recess in the main piston body and is positively locked therein by a retaining ring. A seal ring closes expansion clearance provided at the upper edge of the insert against significant gas flow into the insulating air gap. Insulating efficiency of the air gap is maximized by forming the gap with a thickness throughout a major portion of its extent of between about 0.040 and 0.060 inches.Numerous additional features are also disclosed.

摘要： A method for advising a motor vehicle operator of the need to change the lubricating oil in a direct or an indirect injection diesel engine. The rate of degradation of the engine oil is determined from monitoring engine revolutions, engine oil temperature and engine oil contamination content. At the start of service after an oil change has occurred, a value corresponding to the maximum allowed number of engine revolutions for the useful life of the oil is stored in the memory of the vehicle's computer. Periodically during each period of vehicle operation, an effective engine revolutions value is determined in relation to the product of measured engine revolutions, an engine oil temperature dependent penalty factor and an oil contaminant content dependent penalty factor. The penalty factors increase the effective engine revolutions value to compensate for engine operating conditions that tend to cause increased degradation of the engine oil. The effective engine revolutions value is subtracted from the stored maximum number of engine revolutions resulting in a remaining allowed revolutions value. Each time the effective engine revolutions value is calculated and subtracted from the remaining allowed engine revolutions value, a new remaining allowed revolutions value is stored in memory, replacing the old value. When the stored remaining allowed revolutions value is decreased below a predetermined threshold value indicating the end of the oil's useful life, an indicator advising the operator that the engine oil needs to be changed is activated.
摘要翻译：一种为直升机或间接喷射式柴油发动机改变润滑油需要的机动车辆驾驶员的方法。发动机机油的劣化速率是通过监测发动机转数，发动机机油温度和发动机油污染物含量来确定的。在发生换油之后的服务开始时，将与油的使用寿命的最大允许发动机转数相对应的值存储在车辆的计算机的存储器中。在车辆操作的每个周期期间，相对于所测量的发动机转数，发动机油温度依赖性罚因子和油污染物含量相关罚因子的乘积确定有效的发动机转数。惩罚因素增加了有效的发动机转速值，以补偿容易引起发动机油劣化的发动机工作条件。从所存储的最大发动机转数中减去有效的发动机转数，导致剩余的允许转速值。每当计算出有效的发动机转速值并从剩余允许的发动机转速值中减去时，将新的剩余允许转数值存储在存储器中，代替旧值。当存储的剩余允许转数降低到指示油的使用寿命结束的预定阈值以下时，启动指示操作者需要改变发动机油的指示器。

摘要： A fuel distributing pump for a multi-cylinders, internal combustion engine having a sinuously profiled cam member providing a plurality of discrete compound cam pumping stations, each comprising primary and auxiliary cams serially arranged and interconnected by an intermediate cam segment which cooperate with pumping plungers of a pump rotor to shape and vary the pulse waves of fuel delivered to the combustion chambers for varying engine operations. For low horsepower requirements, such as idle and light loads, only the primary cam with fast initial pumping rate and following low rate camming ramps or surfaces are utilized to shape the pulse wave with a fast beginning and a graduated end of injection for even and progressive fuel burn for reducing smoke and engine noise. For higher engine loads, the primary cam, the interconnecting cam segment and a large part of the auxiliary cam are employed for a fast beginning and end of injection for shaping and increasing the quantities of fuel in the pulse waves pumped for effective high horsepower operation with cleaner exhaust.
