A top portion (140) of a piston (128) of the engine is received by a skirt portion (142) of the cylinder head. The skirt portion has a diameter D4 that is greater than the piston diameter D3 but more than the diameter D1 of a cylinder liner (126). A coolant passage (148) may be formed in the cylinder head proximate the integral anti-polishing ring.

摘要： A method of cooling a locomotive engine wherein the temperature of the coolant flowing into the engine is controlled in response to the temperature of the lube oil flowing out of the engine so that the difference between these two temperatures is limited to a predetermined value in order to limit the differential expansion between parts within the engine. The predetermined value may be a function of the lube oil temperature, and it may have an absolute maximum value. In the event that the temperature difference exceeds a predetermined value, the power output of the engine may be reduced as a function of the length of time that the temperature difference limit has been exceeded. The rate of change in coolant temperature may be limited during periods of decreasing lube oil temperature in order to limit the duty cycle demand on coolant system components.
摘要翻译：一种冷却机车发动机的方法，其中响应于流出发动机的润滑油的温度来控制流入发动机的冷却剂的温度，使得这两个温度之间的差被限制在预定值，以便限制发动机内部件之间的差速膨胀。预定值可以是润滑油温度的函数，并且其可以具有绝对最大值。在温度差超过预定值的情况下，可以根据超过温差极限的时间长度来减小发动机的功率输出。在润滑油温度降低期间，冷却剂温度的变化率可能受到限制，以限制对冷却剂系统部件的占空比要求。

摘要： A diesel locomotive engine (10) having a combustion chamber (30) formed into the cylinder head (16) to have a diameter (D2) greater than the diameter (D1) of the cylinder liner (14). A piston (20) is disposed for reciprocating motion in the cylinder. The piston has a top wall (36) with a convex surface to form a generally ring-shaped combustion volume. A fuel injection nozzle (28) directs a flow of fuel into the combustion chamber in a direction generally along a radius of the generally ring-shaped combustion volume at a pressure of more than 1800 bar in one embodiment. A cooling passage (42) is formed in the cylinder head to remove heat energy, thereby reducing the production of the oxides of nitrogen during engine operation.

摘要： A diesel engine (E) has a combustion chamber (C), a piston (T) movable in the chamber, air intake and exhaust valves (IV, EV), and a nozzle (N) injecting fuel into the combustion chamber. By controlling characteristics of an air-fuel mixture, emissions produced by combustion of the air-fuel mixture in the chamber are reduced to levels which satisfy the Tier 2 requirements established by the Environmental Protection Agency (EPA) for the engine. This may include controlling hydraulic flow characteristics through the nozzle, increasing the compression ratio within the combustion chamber, lowering the manifold air temperature (MAT), and retarding the start of fuel injection (SOI) within the chamber.

摘要： A system for controlling fuel flow in an internal combustion engine receives a command specifying a desired fuel flow rate from an electronic control module. The system generates a feedforward estimate of actuator current required to produce the desired flow rate. This estimate is combined with a fueling current offset value generated using a proportional-integral feedback controller. A differential pressure between the fuel rail and cylinder gas is converted, by surface interpolation based on a lookup table, to an estimate of actual fuel flow rate. The difference between this actual fuel flow rate and the desired flow rate is provided to the feedback controller as an error signal. The feedback controller preferably uses different gain values depending on an operating mode of the engine (speed control and torque control modes).
