摘要： An engine combustion chamber includes a cylinder head, a cylinder wall and a piston. The piston has a bowl volume formed therein. A fuel injector is disposed adjacent one edge of the bowl and an ignition source is within a predetermined distance of another, substantially opposite, edge of the bowl. The bowl has a transporting surface which directs a fuel-air charge from the bowl volume toward the ignition source. The piston, bowl and cylinder head cooperate through a plurality of design features to provide an efficient combustion chamber.

摘要： A method is disclosed for controlling the air-fuel ratio in a four-stroke gasoline direct-injection controlled auto-ignition combustion. The engine is operated with two sequential pairs of expansion and contraction strokes during two revolutions of the engine crank, the two revolutions defining a combustion cycle. A system is employed for variably actuating the intake and exhaust valves and adjusting the flow of air and burned gases entering the combustion chamber. Adjusting the flow affects the resulting air-fuel ratio in the combustion chamber. The valve actuating system is employable to operate the intake and exhaust valves with an exhaust re-compression or an exhaust re-breathing valve strategy. Either valve strategy affects the air-fuel ratio in the cylinder and causes a proportion of burned gases from previous combustion cycles to be retained in the cylinder to provide the necessary conditions for auto-ignition of the air-fuel mixture.

摘要： A method and apparatus for controlling engine operation to compensate for effects of combustion chamber deposits (CCDs) on combustion in a controlled auto-ignition engine is presented. Control methodologies comprise operation of variable valve actuation, fuel injection, spark timing, and intake air and coolant temperature to dynamically compensate for the effect of CCDs. A sensitivity to core gas temperature and chamber wall thermal conditions is shown, which is correlatable to in-cylinder CCD formation. Intake charge or coolant temperature control can be used to compensate for CCD effects. An engine control scheme relies upon a parametric input that quantifies instantaneous CCD formation in the combustion chamber. The result is further applicable to control pre-ignition in a conventional spark-ignition engine.

摘要： A method to control combustion in an HCCI engine, to mitigate effects of combustion chamber deposits is detailed. The method comprises applying a specific surface coating to a combustion chamber surface. The surface coating has thermal properties substantially similar to the combustion chamber deposits. The thermal properties preferably include a) thermal conductivity, b) heat capacity, and c) thermal diffusivity. Applying a surface coating results in a reduction of combustion variability due to variation in combustion chamber deposits, and an improvement on combustion stability at low loads due to reduced heat loss. A preferred thermally insulating surface coating includes thermal parameters of a heat capacity in a range of 0.03×106 J/m3-K to 2.0×106 J/m3-K; a thermal conductivity in a range of 0.25 W/m-K to 2.5 W/m-K; and, a thermal diffusivity in a range of 1×10−7 m2/s to 8×10−6 m2/s.

摘要： A direct injection controlled auto-ignition engine is operated at steady state, within a homogeneous charge compression-ignition (HCCI) load range and with fuel-air-diluent mixtures at predetermined conditions, for each speed and load, of engine control inputs, including at least fueling mass flow rate, injection timing (FI), spark timing (SI) and exhaust recompression obtained by negative valve overlap (NVO). During load change rates below a predetermined threshold, SI, FI and NVO change rates are synchronized to current changes in the fueling mass flow rate. For fast load increases above the threshold, the cylinder charge is temporarily enriched by increasing the percentage of residual gas or reducing the percentage of fresh air mass in the charge sufficiently to maintain auto-ignition temperature during the load change. This may be done by delaying NVO action for a predetermined speed-dependent number of engine cycles. At very low loads, stable fuel rate reduction may require an alternate method involving deceleration fuel cut-off followed by a step change during refire.
摘要翻译：直喷式控制自动点火发动机在均匀充气压缩点火（HCCI）负载范围内以及燃料 - 空气 - 稀释剂混合物在预定条件下对于发动机控制输入的每个速度和负载运行，包括至少燃料质量流量，喷射正时（FI），火花正时（SI）和通过负阀重叠获得的排气再压缩（NVO）。在负载变化率低于预定阈值时，SI，FI和NVO变化率与加油质量流量当前的变化同步。对于快速负载增加超过阈值，通过增加残余气体的百分比或减少充电中的新鲜空气质量百分比来充分地保持气缸充量，以在负载变化期间保持自燃温度，从而暂时增加气瓶充量。这可以通过将NVO动作延迟到预定的速度相关数量的发动机循环来完成。在非常低的负载下，稳定的燃油速率降低可能需要一种替代方法，包括减速燃料切断，然后在重新启动期间改变阶跃。
