Cold start emissions of traffic
Science of The Total Environment, 1990Abstract CO, HC, NOx, particulate emissions and fueld consumption were measured on a chassis dynamometer for both hot and cold start. Three urban driving cycles were used, two ECE15 cycles for tuned and as received vehicles and one representative of the actual driving patterns. 51 cars (gasoline and diesel engines) were tested using this method. From

PHEV Cold Start Emissions Management
SAE International Journal of Alternative Powertrains, 2013<div class="section abstract"><div class="htmlview paragraph">Plug-in hybrid electric vehicles (PHEV) operate predominantly as electric vehicles (EV) with intermittent assist from the engine. As a consequence, the engine can be subjected to multiple cold start events.

Engine Lubrication in Cold Start-Up
SAE Technical Paper Series, 1989<div class="htmlview paragraph">Simulated start-up tests were made in a cold chamber with two gasoline-fueled four-cylinder passenger car engines. The engine was motored with a hydraulic motor according to a certain test programme.</div> <div class="htmlview paragraph">The time required for the oil pressure to build up was measured on

Abatement of automotive cold start hydrocarbon emissions
SAE Technical Paper Series, 2001<div class="htmlview paragraph">This paper reports the results of a study on adsorption properties of zeolitic materials with different pore opening and Si/Al ratio towards engine cold start hydrocarbon emissions. Some selected zeolites were deposited on cordierite honeycomb support by a novel technique. Dynamic adsorption tests were performed at

Recommendation Engine: Semantic Cold Start
SSRN Electronic Journal, 2020In this document, we explore methods to provide useful recommendations until activity data is gathered. We refer to this situation as the cold start: users have no activity history, and items have no ratings. Particularly we explore how to successfully cold start recommendations by applying natural language processing.
