Abstract

There is a growing interest in spark-ignited engines, which could operate on heavy fuels (jet and diesel fuel). The explanation is in good power to weight characteristic of spark-ignited engines unlike diesels. At the same time, the main disadvantage of engines with spark ignition is high fuel consumption under high loads using heavy fuels. This explains the necessity of applying low compression ratio in comparison to gasoline analogues. This study describes the operation process of 2-stroke spark-ignited piston engine, which can conserve the compression ratio of the base gasoline engine (10.5) when operating on heavy fuels. It is explained by using a compressed-air atomizer in combination with spray-guided concept. Ignition is carried out via a standard single-spark automotive ignition system. It is shown that the experimental engine is able to run on heavy fuels without knocking in all base engine load ranges. In addition, the unthrottled control is possible in this concept. The cold start investigation was carried out. The experimental engine is successfully started at an ambient temperature up to −20 °C.
