Increasing fuel efficiency of automobile engines has become a prime motive, as the fossil fuel reserves are limited. This has forced automakers to look into technologies that help utilising the available reserves effectively. A typical three cylinder engine at urban driving speed devours more fuel developing excess power than required. Fuel cutoff is a technique that minimises the excess fuel being burnt. The present work concentrates on performance characteristics obtained by integrating Scuderi Split Cycle concept with Spark Ignited (SI) engine that employs fuel cutoff technology. In the current numerical investigation, performance characteristics of a three cylinder SI engine (used in Volkswagen Polo car) was estimated by extrapolating the results obtained for single cylinder using commercially available Ricardo VECTIS tool. The simulation results are validated against analytical results ascertained in concern to engine working volume and compression ratio.
