Abstract: Changes in ambient light intensity are detected by processing image data from an image capture device to determine, iteratively, a signal-to-noise ratio of the image data. The signal-to-noise ratio is a ratio of average to variance of pixel values for some of the pixels forming the image. A control outputis generated, based on the signal-to-noise ratio, that is responsive to changes in ambient light intensity. The control output is used control a light source of a vehicle.

Abstract: A method of monitoring the usage of an internal combustion engine comprises performing an engine monitoring routine using a local monitoring device attached to an internal combustion engine. The engine monitoring routine includes generating data representative of a plurality of vibrations of an internal combustion engine using a vibration sensor of the local monitoring device, processing the generated data to determine a first value representative of a firing frequency of the internal combustion engine, generating an aggregated summary based on the first value and transmitting the aggregated summary and identification data for the local monitoring device to a remote application. The remote application processes the transmitted aggregated summary based on the identification data to determine engine speed usage data.

Abstract: An engine assembly comprises: an internal combustion engine having: a combustion chamber; an air inlet for supplying air to the combustion chamber; a fuel injector for supplying fuel to the combustion chamber; an exhaust outlet for releasing exhaust gas from the combustion chamber and a rotatable drive shaft, wherein combustion of fuel in air within the combustion chamber results in rotation of the drive shaft. The engine assembly further comprises: a turbocharger system comprising: a turbine configured to recover energy from exhaust gas provided via the exhaust gas outlet; and a turbocharger compressor configured to receive energy from the turbine and thereby to compress air for use in combustion of fuel in the combustion chamber. The engine assembly further comprises: a supercharger system comprising a supercharger compressor configured to receive kinetic energy from the drive shaft and to compress air for use in combustion in the combustion chamber. The engine assembly further comprises: a flywheel configured for kinetic energy storage; a first linkage between the drive shaft and the flywheel, wherein the linkage comprises a variable belt drive; and a second linkage between the first linkage and the supercharger compressor.

Abstract: The present disclosure is directed towards an engine assembly comprising a crankcase, a crankshaft, a lubrication system and fluid guide arrangement. During rotation the crankshaft is configured to drive a crankcase fluid flow in a crankcase chamber. The lubrication system comprises a lubricant drain for a drain fluid flow therethrough extending to a drain aperture at the crankcase chamber. The fluid guide arrangement is located adjacent or in proximity to the drain aperture. The fluid guide arrangement is configured for guiding crankcase fluid flow away from the drain aperture and/or for reducing the pressure of the crankcase fluid flow past the drain aperture, such that drain fluid flows from the lubricant drain.
