- Summary:
- Due to their high average workload and operation in rural areas, substituting internal combustion engines in non-road machinery is still today a challenge. Therefore, sustainable and renewable fuels are in key position for decarbonizing the non-road sector. Fuels compatible with spark-ignited engines have their advantages: Ethanol and biomethane fuels are relatively simple to produce locally from e.g. agricultural residuals and wastes. Furthermore, engines operating stoichiometric require only a three-way catalyst (TWC) to fulfill Stage V emission regulations. The simplicity and cost effectiveness brings several advantages. A bi-fuel (and dual-fuel) engine working on both ethanol and biogas could potential offer a flexible option for e.g. farmers being able of producing the fuels locally and simultaneously get new source of income. The largest technical challenges concerning spark-ignited (SI) engines compared to its diesel counterparts are mainly related to lower engine efficiency. In bi-fuel operation, also the great variation of different fuels stoichiometry sets limitations on regular SI engines. The main focus of this study was therefore to study possible methods for developing a flexible spark-ignited non-road engine fulfilling Stage V emission requirements. The studied test engine was a port fuel injected (PFI) SI-conversion based on a commonly used non-road diesel engine for agricultural application. The engine was equipped with two injectors per cylinder, one directed into the swirl port, the other to the tangential flow portrait Additionally, a single gas injection mixer was added to distribute gaseous fuel for all cylinders at once. Four different injection methods was studied: Single liquid fuel injection separately in both swirl and tangential ports, dual port liquid injection and dual-fuel mode, utilizing both ethanol and methane. The results are compared with both a corresponding Stage V diesel and SI gas engine
