Fluid Flow, Combustion and Efficiency With Early or Late Inlet Valve Closing
(1997) In SAE Transactions, Journal of Engines 106(SAE Technical Paper 972937).- Abstract
- This paper is a study of the effects of valve timing and how it influences the in-cylinder fluid flow, the combustion, and the efficiency of the engine. An engine load of 4.0 bar imepdndedt was achieved by setting the inlet valve closing time early or late to enable unthrottle operation. Inlet valve deactivation was also used and asymmetrical valve timing, i.e., valve timing with the two inlet valves opening and closing at different times. The valve timing was altered by switching cam lobes between the experiments.
