摘要： Embodiments for operating an engine with direct injection are provided. In one example, a method for operating an applied-ignition internal combustion engine having at least one cylinder and direct injection comprises raising a component temperature of an injection device of the at least one cylinder at least locally in a region of a catalytic coating in order to initiate and assist oxidation of coking residues. Thus, deposits of coking residues may be counteracted even in part-load operation.

摘要： In a method for operating an internal combustion engine with direct fuel injection, in which air and a first fuel quantity are fed to a combustion chamber, in such a manner that a homogenous lean base mixture is formed in the combustion chamber, and a second fuel quantity is introduced into the combustion chamber in the region of a top dead center position of the piston, in such a manner that an ignitable mixture cloud is formed within the homogenous lean base mixture in the region of an ignition source, and the mixture cloud formed by the second fuel quantity is ignited by means of the ignition source, so that the lean homogenous base mixture which is present in the combustion chamber is compressed by the combustion of the mixture cloud formed by the second fuel quantity and ignited thereby.

摘要： The invention provides a scheme for combusting a hydrocarbon fuel to generate and extract enhanced translational energy. In the scheme, hydrocarbon fuel is nanopartitioned into nanometric fuel regions each having a diameter less than about 1000 angstroms; and either before or after the nanopartitioning, the fuel is introduced into a combustion chamber. In the combustion chamber, a shock wave excitation of at least about 50,000 psi and with an excitation rise time of less than about 100 nanoseconds is applied to the fuel. A fuel partitioned into such nanometric quantum confinement regions enables a quantum mechanical condition in which translational energy modes of the fuel are amplified, whereby the average energy of the translational energy mode levels is higher than it would be for a macro-sized, unpartitioned fuel. Combustion of such a nanopartitioned fuel provides enhanced translational energy extraction by way of, e.g., a reciprocating piston because only the translational energy mode of combustion products appreciably contributes to momentum exchange with the piston. The shock wave excitation provided by the invention, as applied to combustion of any fuel, and preferably to a nanopartitioned fuel, enhances translational energy extraction and exchange during combustion by enhancing translational energy mode amplification in the fuel and by enhancing transfer of an appreciable amount of energy from that translational mode to the piston before the combusted fuel re-equilibrates the translational energy into other energy modes.
摘要翻译：本发明提供一种用于燃烧碳氢化合物燃料以产生和提取增强的平移能量的方案。在该方案中，碳氢化合物燃料被纳米级纳入每个直径小于约1000埃的纳米燃料区域; 并且在纳米颗粒之前或之后，将燃料引入燃烧室。在燃烧室中，至少约50,000psi的冲击波激发和小于约100纳秒的激发上升时间被施加到燃料。分配到这种纳米量子限制区域中的燃料使得能够扩大燃料的平移能量模式的量子力学条件，由此平移能量模式水平的平均能量高于对于大型未分配燃料的平均能量。这种纳米颗粒燃料的燃烧通过例如往复活塞提供增强的平移能量提取，因为只有燃烧产物的平移能量模式明显有助于与活塞的动量交换。本发明提供的冲击波激发，适用于任何燃料的燃烧，优选应用于纳米颗粒的燃料，通过增加燃料中的平移能量模式扩增，并通过增强转移可观量的燃料来增强燃烧过程中的平移能量提取和交换在燃烧的燃料将平移能量重新平衡到其他能量模式之前，从该平移模式到活塞的能量。

摘要： A Stratified Charge Engine where the main combustion chamber is made into one part of the cylinder head is described. The main combustion chamber in this engine is smaller than in Pre-Mixture Combustion Engines. Other main features of this engines are direct fuel injection, installation of a squish area and prevention of combustion in the end-gas zone. The thermal load and the weight of the piston in this engine are lower than in normal Stratified Charge Engines with fuel jet impingement. The fuel jet is kept inside the main combustion chamber, resulting in an higher anti-knocking quality of this engine as compared to Pre-Mixture Combustion Engines.
