Problems solved by technology

[0006] With such a dramatic increase in combustion efficiency, the use of this system has limitations, especially in naturally aspirated diesel engines, where the engine cannot draw in enough air to burn the increased diesel efficiently
This limitation is a result of the manufacture and design of engines configured to burn diesel fuel relatively inefficiently compared to engines operating the methods and systems described above

Embodiment Construction

[0010] specific implementation plan

[0011] A method for engine flameout protection control, characterized in that, according to the pre-calibrated atmospheric pressure in the ECU, the engine target idle speed, the relationship table between the first flameout protection speed and the second flameout protection speed, to determine the measured atmospheric pressure The engine target idle speed calibration value corresponding to the pressure, the first flameout protection speed calibration value and the second flameout protection speed calibration value, wherein the engine target idle speed is greater than the first flameout protection speed, and the first flameout protection speed greater than the second flameout protection speed; engine revolutions per minute of the engine; voltage output of the alternator or other engine signal source of the diesel fuel engine; engine manifold absolute pressure; turbocharger pressure ; throttle valve position; exhaust gas temperature; nitrou...

Abstract

The invention relates to an engine flame-out protection control method. The engine flame-out protection control method is characterized by comprising the step that according to a relation table among the atmospheric pressure, the engine target idle speed, the first flame-out protecting rotation speed and the second flame-out protecting rotation speed which are marked in an ECU in advance, the absolute pressure of an engine manifold, the turbocharger pressure, the throttling valve position, the exhaust temperature, the nitrous oxide gas emission concentration and an engine dynameter are determined.

Description

technical field [0001] The invention relates to a method for engine flameout protection control, in particular to a method for burning diesel fuel in a diesel fuel engine. Background technique [0002] Over the years, diesel fueled engines have been widely used in a large number of applications, such as in transportation, heavy machinery or power generation applications, and form an important part of many pieces of equipment in agriculture, mining, construction, and freight and passenger transportation. It is well known that combustible gases can be added to the intake air of diesel fueled engines. The mixing of the combustible gases with the regular intake air enhances the combustion conditions within the cylinder, thereby increasing the efficiency of the diesel combustion process. [0003] Typically in the prior art, a source of combustible gas, such as liquefied petroleum gas (LPG), is connected to the air inlet of a diesel fueled engine and injected at a certain predete...
