Embodiment

[0031] The present invention will be further described in detail below through specific embodiments. The following embodiments may enable those skilled in the art to understand the present invention more comprehensively, but do not limit the present invention in any form.

[0032] Such as Figure 1-3 As shown,

[0033] The constant volume combustion bomb system that simulates engine combustion includes:

[0034] Combustion bomb with a cylindrical cavity. The combustion bomb is normalized forged with 16MnRE steel to form a uniform high-temperature and iso-volume high-temperature and high-pressure environment, which can simulate the high-temperature, high-pressure, and constant-pressure conditions of the diesel engine piston at the top dead center position. Containment environment; the two end faces of the combustion bomb body are respectively installed with high-temperature and high-pressure-resistant high-transmittance quartz glass to form an optical path. The high-transmission quar...

Abstract

The invention relates to a constant-volume firebomb system for simulating combustion of an engine, for solving the technical problems of difficult observation of a flame combustion process in an actual engine, difficult evaluation and determination of a charcoal smoke generation amount at certain time in the combustion process and difficult realization of real-time sampling analysis of combustion products under the condition of a single variable. The constant-volume firebomb system for simulating the combustion of the engine comprises the following components: a firebomb body with a cylindrical cavity; a heating interlayer nested in the periphery of the firebomb body; a fuel injector; a pressure sensor; a temperature sensor; an air inlet channel; an exhaust sampling system; a high-pressure injection fuel oil supply system; a synchronization data acquisition system; a highs-speed shooting system; and a single-chip microcomputer control system. The constant-volume firebomb system provided by the invention has the following advantages: compared to a specially reconstructed single-cylinder machine or a rapid compressor, the cost is lower, and accurate control of the single variable is easily realized.

Description

Technical field: [0001] The invention relates to a constant volume combustion bomb test device for engine combustion, and further relates to a constant volume combustion bomb system for simulating engine combustion. Background technique: [0002] With the rapid increase in the number of vehicles, the impact of vehicle exhaust emissions on air pollution has become increasingly serious, and vehicle exhaust pollutants have become the main source of air pollution. In order to further reduce the emission of soot particles and nitrogen oxides of the engine and meet the requirements of increasingly stringent emission regulations, the high-pressure common rail technology and the intake port premixed high-octane fuel are directly injected into the cylinder with high cetane fuel. Combined combustion technology has received extensive attention and applications. [0003] Chinese patent CN1470752A discloses Diesel Methanol Compound Combustion (DMCC) technology. It proposes a methanol-diesel co...
