The tuning of a small four-stroke spark ignition engine for flexible valve timings through numerical approach

Variable valve timing has been implemented by various manufacturers to improve internal combustion engine performance while operating at wide speed and load ranges. A novel flexible valve timing system for a small four-stroke engine is currently under development by Automotive Engineering Research G...
