Spark ICE compared to diesel have a substantially lower initial cost, a higher power density, low specific gravity, the relatively simple catalytic treatment, but at the same time, at 15 ... 35% lower fuel efficiency. According to experts, the introduction of independent valve timing drive in the design of automobile spark-ignition engines will reduce average fuel consumption by 20 ... 25% by optimizing valve timing, reducing pumping losses and cutting off the cylinders at low loads. Despite the fact that the independent drive has not reached the industrial implementation it rational application today requires some elaboration. This applies, above all, the choice of optimum operating conditions of drive in terms of maximum efficiency workflow engine. Part of this work with some simplifications carried out on the engine is not having a full-fledged system naturally. Experimental research of idle mode and selection of an appropriate management scheme presented.
