A Study of the Rankine Cycle Generating System for Heavy

Apr 01, 2014 · In heavy duty (HD) trucks cruising on expressway, about 60% of input fuel energy is wasted as losses. So it is important to recover them to improve fuel economy of them. As a waste heat recovery system, a Rankine cycle generating system was selected. And this paper mainly reports it.In this study, e

Using the Equal-Power-Based MCE to Transform Driving

Sep 09, 2021 · Chassis dynamometer testing based on representative driving cycles is commonly performed in the evaluation of the fuel economy of heavy-duty vehicles. However, the requirement for a zero or fixed grade when using a traditional chassis dynamometer results in the inaccurate testing of the fuel economy of a vehicle to be driven on hilly roads. Against this background …
