    摘要： A control method of an internal combustion engine and an internal combustion engine applying the same. Each cylinder is provided with a throttle valve, or a plurality of paralleled throttle valves are employed to supply air for different cylinders or cylinder groups, so that different cylinders are provided with different inlet pressure and inlet airflow, different spark ignition timing (phase angle), different injection timing (phase angle), and different injection quantity, and in a complete work cycle, some cylinders of the engine operate under a compression ignition combustion mode, and some cylinders of the engine operate under a spark ignition combustion mode. When the conditions for compression ignition combustion mode are satisfied, the cylinders adopt the compression ignition combustion mode as much as possible, so as to improve the thermal power efficiency of the engine. The internal combustion engine or vehicle installed with the control method has wide adaptability to different fuel with different ignition points, can detect the octane number of gasoline, and consume various octane number gasoline.

    摘要： Disclosed is a homogeneous charge compression ignition and diffusion compression ignition combined ignition control method for low-octane gasoline, using a diffusion compression ignition control mode as a forced ignition measure, to ignite a premixed homogeneous lean oil and gas mixture, and meanwhile to achieve homogeneous charge compression ignition of the oil and gas mixture. During an intake stroke, a fuel is partially injected into the cylinder or an intake manifold, to form a low-concentrated, homogeneous, premixed oil and gas mixture. Before the piston reaches a top dead center during the compression stroke, the remaining part of fuel is injected into the cylinder, diffuses in the air, and spontaneously ignites, thus achieving diffusion compression ignition. A flame is generated in the diffusion compression ignition, and ignites the premixed oil and gas mixture in the cylinder, to achieve ignition and combustion of the homogeneous lean fuel. As the temperature and the pressure rise in the cylinder, multi-point spontaneous ignition occurs within the homogeneous lean oil and gas mixture, thus achieving homogeneous charge compression ignition. Such a combined ignition control method achieves a high compression ratio, lean combustion, stratified combustion, and fast combustion, without causing any knocks. Also disclosed are an insulation method of an internal combustion engine exhaust system, and a product thereof.

    摘要： The present invention relates to a method for joint production of low octane gasoline and high octane gasoline. In the process of oil or light oil rectification, the extraction points of the distillates therein are finely divided, and the temperature ranges for extraction of fractions are narrowed down. Each of the low and high octane components having a high content in the range from C6-C12 (which may be extended to C5-C14 where necessary) is then separately extracted. After that, low octane components are combined into compression ignition low octane gasoline products, while high octane components are combined into high octane gasoline products. The remaining fractions are respectively added as supplementing agents into the low octane gasoline products or high octane gasoline products dependent on their octane ratings. Low octane gasoline is used in compression ignition gasoline engines, while high octane gasoline is used in spark ignition gasoline engines.

    摘要： A compression-ignition low octane gasoline engine. The engine uses low octane gasoline and a compression-ignition method, does not require a spark plug, and compared with ordinary gasoline engines, increases thermal efficiency by approximately 40% and reduces green-house effects caused by emissions by approximately 45%. The “compression-ignition” of the low octane gasoline engine is a diffusion charge compression-ignition, differing from a homogeneous charge compression-ignition. The compression ratio in a cylinder can be 14 to 22, while an ordinary gasoline engine has a compression ratio of 7 to 11. The low octane gasoline engine has a simple structure, easy combustion control, a low noise level, and a low failure rate. As the low octane gasoline can be free of aromatic hydrocarbons, and not require the addition of antiknock agents such as MTBE and MMT, the present novel gasoline engine is a highly efficient, clean, and environmentally friendly internal combustion engine.

    摘要： A hybrid combustion mode of an internal combustion engine and a controller thereof, an internal combustion engine, and an automobile. The hybrid combustion mode of an internal combustion engine comprises: directly injecting fuel in a cylinder, using ignition combustion control when the internal combustion engine is started, and increasing the inlet temperature and inlet pressure by using a turbocharger; using homogeneous charge compression ignition combustion mode when the internal combustion engine is run, and except when the engine flames out, opening all throttles, not performing exhaust relief control on the turbocharger, increasing filled gas amount by using the turbocharger, and increasing the combustion temperature and pressure of a tail end of a cylinder compression stroke; and when the internal combustion engine is low in load, or when it cannot be determined, through the temperature of a water tank and the inlet pressure behind the throttle, that a compression ignition condition is met, switching a combustion control mode from ignition to compression ignition, if a compression ignition state can be switched to smoothly, maintaining the compression ignition combustion mode, and if the compression ignition state cannot be switched to smoothly and therefore the rotation speed of the engine decreases abnormally, quickly recovering the ignition combustion control mode. Cool start of low-octane gasoline internal combustion engine in a low-temperature environment can be implemented.
