Abstract
Propulsion of non-road mobile machinery dedicated for the waste wood chipping these are mainly internal combustion engines. Their construction mainly affects the efficiency of wood chipping processes. Liberal homologation regulations for combustion engines used by non-road mobile machinery lead not only to relatively high emissions of harmful ex-haust gases but also do not force manufacturers to develop these types of machinery. These propulsions are not equipped with systems, structure and subassemblies that are characteristic of today's construction used in passenger cars that are highly efficient with low emissions to the environment. This article presents the most modern review of ignition-injection control systems to be used in spark-ignition internal combustion engines intended for the drive of non-mobile machinery. With a review of the fifty-seven manufacturers of this type of engine conducted in January 2017, only six offer engines with injection systems. Collected data of control systems referring to motor vehicles has shown that the constructions offered by manufacturers as innovative are constructions still significantly different from modern standards. In addition, the available systems for modernization of the systems and research projects were analysed. The results of the analysis will be the basis for modifying existing structures.
