Experimental Study on the Valve Gap in the Gasoline Engine
Powertrain Engineering Department, Dongfeng Motor Corporation Technical Center, 430056, Wuhan, China
The influences of the installations of the camshaft support, and timing system and the heat release on the valve gap of the gasoline engine were analyzed in the present. The experiments were carried out on 50 4-cylinder 4-stroke gasoline engines, and the results indicate that to tighten the camshaft support has a great impact on valve gap, the indicated mean there was an obvious deformation in cylinder head after the camshaft support was tightened. The timing system also has a significant influence on the valve gap because it produces a downward force to the camshaft, leading to a smaller valve gap near the timing system and a bigger valve gap on the other side. It was also found that with the increase of temperature the valve gap was 0.1 mm larger than that in the normal state.
