Mitsubishi SUW

High Quality Content by WIKIPEDIA articles! The Mitsubishi SUW (Smart Utility Wagon) is a series of concept cars sharing a common design theme, and first exhibited by Japanese automaker Mitsubishi Motors at the 1999 Frankfurt and Tokyo Motor Shows. The Smart Utility Wagon theme was introduced late in 1998 as a demonstration of the company's corporate slogan of the time, "Innovation in Motion", which was itself to represent "smart design" and "ecology conscious[ness]". Specifically, SUWs shared the company's gasoline direct injection (GDI) engine technology, a taller roofline for easier entry and exit, and interior space competitive with larger vehicles. The three individual vehicles Mitsubishi produced were the SUW Advance, a five door hatchback family car, the SUW Compact a three door hatchback small car, and the SUW Active sport utility vehicle.

Air/fuel mixing and combustion in DISI engines

The Direct-Injection (DI) combined with downsizing, variable valve timing and turbocharging promises a strong reduction of fuel consumption for Spark-Ignition (SI) engines. The advantages of DI have been widely demonstrated in terms of fuel economy, transient response, air-to-fuel ratio (AFR) control and reduced emissions. The control of fuel spray and air-fuel mixture formation is fundamental for fully taking advantages of DI in SI engines. This work investigates the influence of injection parameters on air/fuel mixture and combustion processes in a DISI engine. In the first part the main fuel spray parameters were investigated: Particle Image Velocimetry allowed to characterize the spray velocity field while Phase Doppler Anemometry was applied for droplets size and velocity measurements. An innovative X-ray tomography technique allowed to investigate the inner structure of the fuel spray in the region immediately downstream of the nozzle. Finally, the effect of the injection duration and phasing on the combustion process and pollutant emissions formation was studied in a GDI optically accessible engine, through UV-visible imaging and spectroscopy.

Mitsubishi 8A8 engine

High Quality Content by WIKIPEDIA articles! The Mitsubishi 8A8 engine is a range of V8 powerplants produced by Mitsubishi Motors since 1999. The only variant to date is the 8A80, a 4.5 L with double overhead camshafts and gasoline direct injection (GDI) technology. Financial pressures forced the company to discontinue sales of the Proudia and Dignity, the only vehicles in its range to which it was fitted, after only fifteen months. However, the two vehicles were developed in partnership with the Hyundai Motor Company of South Korea, with whom Mitsubishi has had a longstanding relationship.[3] While Mitsubishi makes the cylinder heads and other GDI-related equipment, Hyundai casts the aluminium block, and other major internal components. Hyundai's version of the Proudia/Dignity, the Equus, proved more successful, and this has been the sole application of the powerplant since 2001. Hyundai replaced the engine with its newly developed Tau V8 in 2008 when the second generation rear wheel drive Equus replaced the first model.

The development and introduction of new engine technologies are primarily motivated by the need to comply with increasingly stringent emissions legislation and to reduce fuel consumption. One of the most important of these new engine technologies is Gasoline Direct Injection (GDI), which is considered to be an important and cost-effective measure to meet both targets. Computational Fluid Dynamics (CFD) simulations and optical methods are important tools in the development of direct injection gasoline engines. The aim of this work was to develop models, methods, and a numerical platform for simulating the behavior of GDI engines using a variety of fuels, including gasoline-ethanol blends. One of the most important goals of this work was to devise improvements to OpenFOAM (a free, open source CFD package) that would increase its utility as a tool for studying GDI engines, as there is strong industrial demand for inexpensive software. This book addressed two important problems relevant to modelling combustion in a GDI engine, including combustion chemistry and spray modelling.

Understanding highly complex nature of flow in an IC engine is essential to optimize its performance. However, the events like reciprocating motion of piston, motion of valves, turbulence generation, spray and mixing lead to a complex flow pattern. CFD is very useful in computing and understanding this complex flow pattern. In this book, all aspects of CFD technique to simulate the mixing of fuel with air in GDI engines are explained. The book covers the governing equations, numerical techniques for solving them, method of analysis of data (in the context of mixing processes) and programming techniques. The book will be useful for professionals who are performing CFD analysis using CFD softwares for thermal systems specifically reciprocating systems like engines, compressors and systems involving sprays, mixing etc. It is also useful for those who are developing CFD tools.

High Quality Content by WIKIPEDIA articles! The Mitsubishi Dignity, whose name was derived from "the English to describe the peerless grandeur and majestic stateliness of the model", is a limousine manufactured by Mitsubishi Motors from late 1999 as the flagship of the company's domestic range, alongside the smaller Proudia luxury car. The entire Proudia/Dignity range was designed by Mitsubishi Motors and co-manufactured with Hyundai of South Korea, who marketed their own version as the Hyundai Equus. The Yen 9,990,000 Dignity featured Mitsubishi's 8A80 4498 cc V8, a 90-degree aluminium- block GDi engine producing 280 PS (206 kW) at 5000 rpm and 412 N m (304 lb ft) at 4000 rpm,[1] and an extension of the Proudia's exterior dimensions in order to liberate more interior space for the rear occupants, the roofline was raised by 10 mm (0.4 in) and the wheelbase by 250 mm (9.8 in). The car was equipped with several advanced features like CCD cameras to monitor adjacent lanes and behind the car, and a laser activated adaptive cruise control.

The flow behavior of liquid fuel through injectors greatly affects its atomization and combustion efficiency inside an engine. A computational fluid dynamics (CFD) model is developed using the open source CFD library OpenFOAM to predict the fuel flow in injectors that are used in the gasoline direct injection systems (GDI). Additionally, a method is formulated to couple this model with fluids that represent the physical properties of gasoline-ethanol blends like E85.

Common Rail System for GDI Engines

Progressive reductions in vehicle emission requirements have forced the automotive industry to invest in research and development of alternative control strategies. Continual control action exerted by a dedicated electronic control unit ensures that best performance in terms of pollutant emissions and power density is married with driveability and diagnostics. Gasoline direct injection (GDI) engine technology is a way to attain these goals.This brief describes the functioning of a GDI engine equipped with a common rail (CR) system, and the devices necessary to run test-bench experiments in detail. The text should prove instructive to researchers in engine control and students are recommended to this brief as their first approach to this technology. Later chapters of the brief relate an innovative strategy designed to assist with the engine management system, injection pressure regulation for fuel pressure stabilization in the CR fuel line is proposed and validated by experiment. The resulting control scheme is composed of a feedback integral action and a static model-based feed-forward action, the gains of which are scheduled as a function of fundamental plant parameters. The tuning of closed-loop performance is supported by an analysis of the phase-margin and the sensitivity function. Experimental results confirm the effectiveness of the control algorithm in regulating the mean-value rail pressure independently from engine working conditions (engine speed and time of injection) with limited design effort.
