Problems solved by technology

A high intake air temperature will reduce the cylinder charging efficiency, lead to an increase in combustion temperature, increase the heat load on the piston, cylinder head and cylinder liner, and increase the NOx content in the exhaust gas, making the NOx emission prediction value of the single-cylinder engine higher, resulting in Single-cylinder engines are not accurate enough to predict overall machine performance, reliability and emissions

Abstract

The invention relates to an air inlet boundary control apparatus of a single-cylinder engine. The air inlet boundary control apparatus comprises an air compressor, a plate-type heat exchanger, a freezer dryer, an air inlet heater and other components. Under different environment conditions and different operation conditions, the single-cylinder engine acquires a same air inlet temperature with the air inlet temperature of a whole machine. Compared to an existing single-cylinder engine air inlet system, by using the air inlet boundary control apparatus of the single-cylinder engine of the invention, an air inlet temperature adjusting range is large so that the single-cylinder engine can accurately simulate an air inlet boundary condition of the whole machine under the different environment conditions and the different operation conditions, which is good for accurately predicting performance and discharge of the whole machine. In addition, the invention also provides an air inlet boundary control method of the single-cylinder engine.

Description

technical field [0001] The invention relates to an intake system of an engine, in particular to an intake boundary control device and method for a single-cylinder engine. Background technique [0002] The single-cylinder engine has the advantages of simple design and manufacture, strong independence of each parameter during the test, a small number of test pieces to be replaced, and a significant reduction in test cost. It is a commonly used testing machine. In the process of developing a new engine model, it is necessary to screen the component matching scheme and verify the reliability of the main components through the single-cylinder engine test, so as to reduce the test cost and development risk of the whole machine. For large marine engines, due to the high cost of the whole machine and the high cost of testing, it is more important to carry out component development and performance verification tests in advance by simulating the whole machine with a single-cylinder en...
