WebApr 3, 2024 · Development of a Virtual CFR Engine Model for Knocking Combustion Analysis Full Record Related Research Abstract Knock is a major bottleneck to achieving higher thermal efficiency in spark ignition (SI) engines. The overall tendency to knock is highly dependent on fuel anti-knock quality as well as engine operating conditions. WebApr 10, 2024 · The CFR engine is the widely accepted platform to test standard Research Octane Number (RON) and Motored Octane Number (MON) for determining anti-knock characteristics of motor fuels.

WebMar 19, 2024 · Since the standardised methods for obtaining information about fuel properties are time consuming and expensive (for example, CFR Knock Engines), chemometric methods linking the IR method with fuel properties became popular. WebIt is, therefore, critical to gain a better understanding of fuel-engine interactions in order to develop robust knock mitigation strategies. In the present work, a numerical model based on three-dimensional (3-D) computational fluid dynamics (CFD) was developed to capture knock in a Cooperative Fuel Research (CFR) engine. WebThe components include the detonation pickup that screws into the cfr engines cylinder, a detonation meter, a power supply, and an electronic display knock-meter. Knock … river thames boating map
