A Fully Variable Valve In An Optimized 2-Stroke Diesel Engine
Added Jul 16, 2014 | Rate View top rated
Future engines must meet tough fuel economy and emissions standards without sacrificing power. Variable valve actuation (VVA) can help, but current engines with VVA all have camshafts, so they are not fully variable. LIM Technology has invented a pneumatically actuated, digitally managed valve which is fully variable and requires no camshaft. The video shows how a LIM valve works in our 2-stroke engine, and how it might work in a 4-stroke engine.
