Improvements in vehicle efficiency will be a key factor in ensuring that liquid fuels remain a vital partner in the future of road transport. This article looks at the role of high-octane petrol (HOP) in improving engine efficiency, and summarises the findings of a...
Concawe’s modelling and vehicle testing study shows that fuels and vehicles can be optimised together to take advantage of higher-RON fuels, and achieve significant improvements in efficiency and CO2 emissions.
Gasoline combustion has traditionally been measured using Research Octane Number (RON) and Motor Octane Number (MON) which describe the fuel’s resistance to auto-ignition (commonly known as ‘knock’) under different conditions. All modern European gasoline cars must be...
Report no. 6/20: Stoichiometric engines running on natural gas rely on three-way catalysts to meet limits e.g. Euro 6 regarding emissions of hydrocarbons (including methane), carbon monoxide and oxides of nitrogen. As is well known from decades of industry experience...
Report no. 5/20: In Europe, the development and implementation of new regulatory test procedures including the chassis dynamometer (CD) based World Harmonised Light Duty Test Procedure (WLTP) and the road-based Real Driving Emissions (RDE) procedure, has been driven...
