A high-temperature and smoke-resistant monitoring lens for fuel injector combustion

Abstract

The invention proposes a high-temperature-resistant and smoke-resistant monitoring lens for the actual combustion of the fuel injection port, which includes a fuel injector body and a fuel injector nozzle. A temperature cover, and the temperature-resistant cover can rotate relative to the monitoring lens. The temperature-resistant cover is a hollow ring with an unsealed bottom end. The monitoring lens is set in the hollow inner cavity of the hollow ring. The bottom of the connecting block is provided with a wiping layer that touches the lens of the monitoring lens. The heat-resistant cover for this application has excellent high temperature resistance and anti-fogging effects, which provides a guarantee for the precise monitoring of the monitoring lens. The thermal effectiveness is significantly extended, the lens protection effect is good, efficient and practical, and the application is cost-effective.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to a high-temperature-resistant and smoke-resistant monitoring lens for live fuel injection port combustion. Background technique [0002] The fuel injector is a precision device with very high machining accuracy, which requires a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The fuel injector receives the fuel injection pulse signal sent by the ECU to precisely control the fuel injection quantity. [0003] The spray characteristics of the injector include atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle, etc. These characteristics should meet the requirements of the diesel engine combustion system, so that the formation and combustion of the mixture can be perfected, and higher power and thermal efficiency can be obtained. [0004] The fuel injector is one of the ...

Problems solved by technology

[0004] The fuel injector is one of the very important components in the application of the engine. Once a failure occurs, the operation of the entire device will be interrupted, which will greatly affect the work efficiency. Therefore, it is necessary to set the fuel injector operation monitoring

When the fuel injector is running, the oil mist combustion will generate high temperature and even smoke, which has caused great troubles for the accurate monitoring of the monitoring device. In this regard, this application proposes a high temperature resistant anti-corrosion smoke lens
