Automobile engine development and test system

Abstract

The invention provides an automobile engine development and test system. The automobile engine development and test system comprises a dynamometer, a vacuumizing device, a high-pressure oil supply device, a combustion analyzer, an air inlet pressure control device and a control device, the dynamometer is in transmission connection with the single-cylinder engine through a transmission shaft; the vacuumizing device is connected with an engine crankcase; the high-pressure oil supply device is communicated with an air inlet of the single-cylinder engine so as to provide required oil supply pressure; the combustion analyzer is communicated with a combustion chamber of the single-cylinder engine so as to collect combustion data; the air inlet pressure control device is communicated with an air inlet of the single-cylinder engine, so that the air inlet pressure of the single-cylinder engine is adjusted; the control device is electrically connected with the dynamometer, the high-pressure oil supply device, the combustion analyzer and the air inlet pressure control device; by the adoption of the scheme, the engine design scheme with the most cost performance is obtained by integrating technology combination comparison tests of variable compression ratio, variable air inlet tumble ratio, variable valve timing lift and the like, and the engine design scheme has the advantages of being short in development period and low in development cost.

Description

technical field [0001] The invention belongs to the technical field of automobile engine development and testing systems, and in particular relates to an automobile engine development and testing system. Background technique [0002] With China's accession to the WTO (World Trade Organization) in 2003, all aspects of China's economy have achieved rapid development. Among them, the auto industry has become increasingly competitive with the addition of many independent national brands, constantly breaking the monopoly of foreign auto companies on the market. With the rapid development of the economy, people's economic income has increased significantly, and cars, as people's daily consumer goods, have gradually entered ordinary families. However, since China's car ownership per 1,000 people is still low, the overall car ownership will continue to increase; with the increase in car ownership year by year, energy consumption and environmental pollution have gradually attracted n...
