Abstract:In this paper we demonstrate the potential of combining electric hybridization with a dual-fuel natural gas-Diesel engine. We show that carbon dioxide emissions can be reduced to 43 gram per kilometer with a subcompact car on the New European Driving Cycle (NEDC). The vehicle is operated in charge-sustaining mode, which means that all energy is provided by the fuel. The result is obtained by hardware-in-the-loop experiments where the engine is operated on a test bench while the rest of the powertrain as well as the vehicle are simulated. By static engine measurements we demonstrate that the natural gas-Diesel engine reaches efficiencies of up to 39.5%. The engine is operated lean at low loads with low engine out nitrogen oxide emissions such that no nitrogen oxide aftertreatment is necessary. At medium to high loads the engine is operated stoichiometrically, which enables the use of a cost-efficient three-way catalytic converter. By vehicle emulation of a non-hybrid vehicle on the Worldwide harmonized Light vehicles Test Procedure (WLTP), we demonstrate that transient operation of the natural gas-Diesel engine is also possible, thus enabling a non-hybridized powertrain as well.

“…A performance test of the proposed PMS, as well as a dynamic vehicle model development, was carried out in a Matlab/Simulink® environment. The 2-L, 4-stroke Volkswagen engine [42] was modelled using two lookup tables. The generator and traction motor were approximated using DC motor models.…”

“…In this work, the range extender can operate at five different rates, as presented in Table 1. Fuel economy and inertia effect are significant concerns in selecting load points from the fuel consumption map of the 2-L, 4-stroke Volkswagen engine [42]. This work utilises six binary variables to represent on-off states of the load points: n RE ={n RE,1 ,…,n RE,6 } and n RE,i ∈{0,1}.…”

Optimisation-Based Power Management System for an Electric Vehicle with a Hybrid Energy Storage System

Hybridisation of energy storage sources is necessary for extending mileage of electric vehicles. However, coordination of multiple devices with different characteristics is challenging. This paper presents a power management system (PMS) for an electric car equipped with a battery pack, supercapacitor bank, and range extender. The proposed PMS deals with vehicular load distribution by solving a power management problem, formulated as a constrained quadratic program (CQP). Then, the optimised variables, such as the desired speed and optimised operation points of the car’s components, are implemented by controllers at a component level. Complete knowledge about the trip is unwanted because the proposed PMS considers a power management problem only over a controlled horizon of one sampling period. Furthermore, this work varies weight factors to tackle various difficulties, for instance, regenerative power management. The simulation results revealed that the proposed system optimally allocated an electric power load to the car components, without violating any physical constraints. Also, the comparative study showed that the performance of the CQP in power management was comparable to that of the benchmark, based on a nonlinear model predictive control.

Conventional and low temperature diesel combustion systems are reviewed from a broad perspective, beginning with a summary of practical design considerations. This material will provide practicing engineers a comprehensive review, and for those new to the field, an overview of what is essential and references for further information. The practical considerations are followed by a description of the fundamental physical processes controlling the combustion process. With this background, an overview of the evolution of the combustion process is provided and the impact of various design parameters on this evolution is discussed. Our objective is to provide the combustion system designer a strong physical understanding to guide his development of modern, low emission, high efficiency diesel combustion systems.
