“…• There are many literature items presenting specific solutions aimed at reducing emissions, often of a comparative nature (the use of different fuels or non-engine exhaust gas treatment systems). These publications include such solutions as: the development of an electronic fuel injection system [64], the modification of the catalytic coating of a three-function catalytic reactor [65] and the comparative analysis of the use of fuel with different sulfur contents [66]. Moreover, items such as [67][68][69][70] describe the research and analysis of particulate emissions unregulated until 2020 and the introduction of the Euro 5 standard.…”

Two-wheeled vehicles, due to their population, constitute a significant share of road vehicles in Europe. Therefore, this article presents an overview and analysis of the applicable legal regulations regarding two-wheeled vehicle engines in terms of toxic exhaust emission tests. For the correct interpretation of emission standards, the authors of this work made the necessary analysis of the categorization of two-wheeled vehicles based on Polish law and the criteria of European regulations. The presented analysis concerns not only the current regulations, but also their development trends over the years. These considerations are supplemented with a literature review, which includes the problems of the ecology, energy consumption and construction of the considered group of vehicles. The work presented in this article also concerns the assessment of the conditions for conducting tests on objects belonging to category L in laboratory conditions on chassis dynamometers. On this basis, considerations were made to evaluate the currently applicable WMTC (World Motorcycle Test Cycle) test by comparing it with the actual operation of two-wheeled vehicles. This resulted in the formulation of conclusions regarding the need to introduce procedures for testing pollutant emissions in road conditions in the approval process.

<div class="section abstract"><div class="htmlview paragraph">The cold starting and cold-state running cycle (i.e. engine warming up) of gasoline engines are the key points of exhaust emissions formation of modern engines, and also one of the very important targets for the increasingly stringent emissions regulations. The combustion stability in gasoline engine cold starting and warming up will impact the formation of its exhaust emissions. This paper introduces the improvement in cold starting and warming up combustion process for the motorcycle gasoline engine by high-energy, dual-spark plug based rapid burning system. Test results showed that the high-energy, dual-spark plug based rapid burning system was very helpful to rapid ignition under the engine cold starting condition. Meanwhile, because of increasing the burning velocity of the engine mixture, this solution can realize the larger ignition retard and stable combustion process under the engine warming-up condition. As a result, it was very helpful to increase the exhaust gas temperature and shortened the light-off time of TWC to achieve the improvement exhaust emission performances for gasoline engines with EFI.</div></div>
