In this thesis work, a new technique for designing logic circuits called the Modified Gate Diffusion Input (MGDI) logic is discussed. This logic is adopted from the Gate Diffusion Input (GDI) technique. GDI was first proposed in the year 2002 for solving the problems associated with different CMOS logic styles. GDI cell can be used to implement wide variety of complex logic functions using only two transistors. GDI technique allows design of high speed and low power circuits with reduced number of transistors as compared to static CMOS and Pass Transistor Logic (PTL) techniques. This work aims to design a various high performance adders and multipliers.

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.

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. 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.
This book presents design of a low power high speed 1-bit ALU in 45nm CMOS technology. Low power high speed circuit design has emerged as a challenging and an emerging field among circuit designers and researchers. A 1-bit ALU is designed in 45nm CMOS technology by using CMOS, nMOS PTL and GDI circuit techniques and its performance characteristics such as power dissipation, delay, power-delay product and number of transistors are compared. GDI technique provides better performance characteristics for designing a low power high speed VLSI circuit. This circuit technique reduces power dissipation, delay, and it also maintains low complexity in the integrated circuit design. This technique is suitable for designing a low power high speed VLSI circuit by using very less number of transistors as compared to other circuit design techniques. This technique has emerged as an effective circuit technique for designing a low power high speed VLSI circuit. The contributions made in this book would help circuit designers and researchers in designing low power high speed integrated circuits.

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, 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.
Stringent emission regulations aim to restrict soot emissions by particle mass and particle number in the transport sector. Whilst the concept of direct-injection gasoline (GDI) engines is very promising with respect to efficiency, complying with the legislative soot emission limits is challenging for GDI-engines. A sufficient reduction of soot emissions in GDI engines requires a detailed understanding and accurate modeling of soot formation processes of gasoline fuels in engines. This study provides fundamental investigations of the soot formation process of common gasoline surrogate components.Soot volume fraction profiles in laminar counterflow flames burning ethylene, n-heptane, iso-octane, and toluene were determined experimentally for a wide range of flame conditions. Simulations of these flames reveal that applied models are capable of predicting the soot volume fraction with remarkable accuracy for ethylene. For the gasoline surrogate components, however, the overall soot volume fractions are overpredicted. Reaction pathway analysis suggests that, in these flames, more soot precursors are formed via the reaction pathways involving fuel pyrolysis products.Furthermore, flame structure, local gas temperature, local soot volume fraction, and primary soot particle diameter were simultaneously detected by means of optical diagnostics in turbulent toluene flames. Joint statistics of flame and soot properties indicate that, due to differential diffusion of soot, high soot concentrations are present at conditions of low temperatures and low OH concentrations. In the soot oxidation region, the presence of large particles suggest that the oxidation is not sufficiently fast to burn soot completely.
